NUCLEAR REGULATORY COMMISSION

[Docket No. 50-302; NRC-2015-0042]


Duke Energy Florida, Inc.; Crystal River Unit 3 Nuclear 
Generating Station

AGENCY: Nuclear Regulatory Commission.

ACTION: Exemption; issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is granting 
exemptions in response to a request from Duke Energy Florida, Inc. (DEF 
or the licensee) regarding certain emergency planning (EP) 
requirements. The exemptions will eliminate the requirements to 
maintain an offsite radiological emergency plan and reduce the scope of 
onsite emergency planning activities at the Crystal River Unit 3 
Nuclear Generating Station (CR-3) based on the reduced risks of 
accidents that could result in an offsite radiological release at a 
decommissioning nuclear power reactor.

I. Background

    The CR-3 facility is a decommissioning power reactor located in 
Citrus County, Florida. The licensee, DEF, is the holder of CR-3 
Facility Operating License No. DPR-72. The license provides, among 
other things, that the facility is subject to all rules, regulations, 
and orders of the NRC now or hereafter in effect.
    By letter dated February 20, 2013 (ADAMS Accession No. 
ML13056A005), DEF submitted to the NRC a certification in accordance 
with section 50.82(a)(1)(i) of Title 10 of the Code of Federal 
Regulations (10 CFR) indicating it would permanently cease power 
operations, and 10 CFR 50.82(a)(1)(ii) that it had permanently defueled 
the reactor vessel at CR-3. On May 28, 2011, DEF completed the final 
removal of fuel from the reactor vessel at CR-3. As a permanently 
shutdown and defueled facility, and in accordance with section 
50.82(a)(2), DEF is no longer authorized to operate the reactor or 
emplace nuclear fuel into the reactor vessel. CR-3 is still authorized 
to possess and store irradiated (i.e., spent) nuclear fuel. The spent 
fuel is currently being stored onsite in a spent fuel pool (SFP).
    During normal power reactor operations, the forced flow of water 
through the reactor coolant system (RCS) removes heat generated by the 
reactor. The RCS, operating at high temperatures and pressures, 
transfers this heat through the steam generator tubes converting non-
radioactive feedwater to steam, which then flows to the main turbine 
generator to produce electricity. Many of the accident scenarios 
postulated in the updated safety analysis reports (USARs) for operating 
power reactors involve failures or malfunctions of systems,

[[Page 19359]]

which could affect the fuel in the reactor core, which in the most 
severe postulated accidents, would involve the release of large 
quantities of fission products. With the permanent cessation of reactor 
operations at CR-3 and the permanent removal of the fuel from the 
reactor vessel, such accidents are no longer possible. The reactor, 
RCS, and supporting systems are no longer in operation and have no 
function related to the storage of the spent fuel. Therefore, EP 
provisions for postulated accidents involving failure or malfunction of 
the reactor, RCS, or supporting systems are no longer applicable.
    Based on the time that CR-3 has been permanently shutdown 
(approximately 64 months), there is no longer any possibility of an 
offsite radiological release from a design-basis accident that could 
exceed the U.S. Environmental Protection Agency's (EPA) Protective 
Action Guidelines (PAGs) at the exclusion area boundary.
    The EP requirements of 10 CFR 50.47, ``Emergency plans,'' and 
appendix E to 10 CFR part 50, ``Emergency Planning and Preparedness for 
Production and Utilization Facilities,'' continue to apply to nuclear 
power reactors that have permanently ceased operation and have removed 
all fuel from the reactor vessel. There are no explicit regulatory 
provisions distinguishing EP requirements for a power reactor that is 
permanently shutdown and defueled from a reactor that is authorized to 
operate. In order for DEF to modify the CR-3 emergency plan to reflect 
the reduced risk associated with the permanently shutdown and defueled 
condition of CR-3, certain exemptions from the EP regulations must be 
obtained before the CR-3 emergency plan can be amended.

II. Request/Action

    By letter dated September 26, 2013 (ADAMS Accession No. 
ML13274A584), ``Crystal River Unit 3--License Amendment Request #315, 
Revision 0, Permanently Defueled Emergency Plan and Emergency Action 
Level Scheme, and Request for Exemption to Certain Radiological 
Emergency Response Plan Requirements Defined by 10 CFR 50,'' DEF 
requested exemptions from certain EP requirements of 10 CFR part 50 for 
CR-3. More specifically, DEF requested exemptions from certain planning 
standards in 10 CFR 50.47(b) regarding onsite and offsite radiological 
emergency plans for nuclear power reactors; from certain requirements 
in 10 CFR 50.47(c)(2) that require establishment of plume exposure and 
ingestion pathway emergency planning zones for nuclear power reactors; 
and from certain requirements in 10 CFR 50, appendix E, section IV, 
which establishes the elements that make up the content of emergency 
plans. In a letter dated March 28, 2014 (ADAMS Accession No. 
ML14098A072), DEF provided responses to the NRC staff's request for 
additional information (RAI) concerning the proposed exemptions. In a 
letter dated May 7, 2014 (ADAMS Accession No. ML14139A006), DEF 
provided an additional supplemental response to a separate set of RAIs, 
which contained information applicable to the SFP inventory makeup 
strategies for mitigating the potential loss of water inventory due to 
a beyond-design-basis accident. In a letter dated August 28, 2014 
(ADAMS Accession No. ML14251A237), CR-3 provided a supplement, which 
amended its request to align with the exemptions recommended by the NRC 
staff and approved by the Commission in staff requirements memorandum 
(SRM) to SECY-14-0066, ``Request by Dominion Energy Kewaunee, Inc. for 
Exemptions from Certain Emergency Planning Requirements,'' dated August 
7, 2014 (ADAMS Accession No. ML14219A366). The information provided by 
DEF included justifications for each exemption requested. The 
exemptions requested by DEF will eliminate the requirements to maintain 
formal offsite radiological emergency plans, reviewed by the Federal 
Emergency Management Agency (FEMA) under the requirements of 44 CFR 
part 350, and reduce the scope of onsite emergency planning activities. 
DEF stated that application of all of the standards and requirements in 
10 CFR 50.47(b), 10 CFR 50.47(c) and 10 CFR part 50, appendix E is not 
needed for adequate emergency response capability based on the reduced 
risks at the permanently shutdown and defueled facility. If offsite 
protective actions were needed for a very unlikely accident that could 
challenge the safe storage of spent fuel at CR-3, provisions exist for 
offsite agencies to take protective actions using a comprehensive 
emergency management plan (CEMP) under the National Preparedness System 
to protect the health and safety of the public. A CEMP in this context, 
also referred to as an emergency operations plan (EOP), is addressed in 
FEMA's Comprehensive Preparedness Guide 101, ``Developing and 
Maintaining Emergency Operations Plans.'' Comprehensive Preparedness 
Guide 101 is the foundation for State, territorial, Tribal, and local 
emergency planning in the United States. It promotes a common 
understanding of the fundamentals of risk-informed planning and 
decision making and helps planners at all levels of government in their 
efforts to develop and maintain viable, all-hazards, all-threats 
emergency plans. An EOP is flexible enough for use in all emergencies. 
It describes how people and property will be protected; details who is 
responsible for carrying out specific actions; identifies the 
personnel, equipment, facilities, supplies and other resources 
available; and outlines how all actions will be coordinated. A CEMP is 
often referred to as a synonym for ``all hazards planning.''

III. Discussion

    In accordance with 10 CFR 50.12, ``Specific exemptions,'' the 
Commission may, upon application by any interested person or upon its 
own initiative, grant exemptions from the requirements of 10 CFR part 
50 when: (1) The exemptions are authorized by law, will not present an 
undue risk to public health or safety, and are consistent with the 
common defense and security; and (2) any of the special circumstances 
listed in 10 CFR 50.12(a)(2) are present. These special circumstances 
include, among other things, that the application of the regulation in 
the particular circumstances would not serve the underlying purpose of 
the rule or is not necessary to achieve the underlying purpose of the 
rule.
    As noted previously, the current EP regulations contained in 10 CFR 
50.47(b) and appendix E to 10 CFR part 50 apply to both operating and 
shutdown power reactors. The NRC has consistently acknowledged that the 
risk of an offsite radiological release at a power reactor that has 
permanently ceased operations and removed fuel from the reactor vessel 
is significantly lower, and the types of possible accidents are 
significantly fewer, than at an operating power reactor. However, 
current EP regulations do not recognize that once a power reactor 
permanently ceases operation, the risk of a large radiological release 
from credible emergency accident scenarios is significantly reduced. 
The reduced risk for any significant offsite radiological release is 
based on two factors. One factor is the elimination of accidents 
applicable only to an operating power reactor, resulting in fewer 
credible accident scenarios. The second factor is the reduced short-
lived radionuclide inventory and decay heat production due to 
radioactive decay. Due to the permanently defueled status of the 
reactor, no new spent fuel will be added to the SFP and the 
radionuclides in the

[[Page 19360]]

current spent fuel will continue to decay as the spent fuel ages. The 
irradiated fuel will produce less heat due to radioactive decay, 
increasing the available time to mitigate the SFP inventory loss. The 
NRC's NUREG-1738, ``Technical Study of Spent Fuel Pool Accident Risk at 
Decommissioning Nuclear Power Plants,'' dated February 2001 (ADAMS 
Accession No. ML010430066), confirmed that for permanently shutdown and 
defueled power reactors bounded by the assumptions and conditions in 
the report, the risk of offsite radiological release is significantly 
less than for an operating power reactor.
    EP exemptions similar to those requested by DEF were granted to 
permanently shutdown and defueled power reactor licensees, such as for 
Zion Nuclear Power Station in 1999 (ADAMS Legacy Accession No. 
9909070079) and Kewaunee Power Station in 2014 (ADAMS Accession No. 
ML14261A223). However, the exemptions did not relieve the licensees of 
all EP requirements. Rather, the exemptions allowed the licensees to 
modify their emergency plans commensurate with the credible site-
specific risks that were consistent with a permanently shutdown and 
defueled status. Specifically, approval of the prior exemptions was 
based on demonstrating that: (1) The radiological consequences of 
design-basis accidents would not exceed the limits of the EPA PAGs at 
the exclusion area boundary; and (2) in the unlikely event of a beyond-
design-basis accident resulting in a loss of all modes of heat transfer 
from the fuel stored in the SFP, there is sufficient time to initiate 
appropriate mitigating actions, and if needed, for offsite authorities 
to implement offsite protective actions using a CEMP approach to 
protect the health and safety of the public.
    With respect to design-basis accidents at CR-3, the licensee 
provided analyses demonstrating that none would warrant an offsite 
radiological emergency plan meeting the requirements of 10 CFR part 50.
    With respect to beyond-design-basis accidents at CR-3, the licensee 
analyzed two bounding beyond-design-basis accidents that have a 
potential for a significant offsite release. One of these beyond-
design-basis accidents involves a complete loss of SFP water inventory, 
where cooling of the spent fuel would be primarily accomplished by 
natural circulation of air through the uncovered spent fuel assemblies. 
The licensee's analysis of this accident shows that as of September 26, 
2013, air cooling of the spent fuel assemblies was sufficient to keep 
the fuel within a safe temperature range indefinitely without fuel 
damage or offsite radiological release. The second beyond-design-basis 
accident analysis performed by the licensee could not completely rule 
out the possibility of a radiological release from an SFP. This more 
limiting analysis assumes an incomplete drain down of the SFP water, or 
some other catastrophic event (such as a complete drainage of the SFP 
with rearrangement of spent fuel rack geometry and/or the addition of 
rubble to the SFP) that would effectively impede any decay heat removal 
through all possible modes of cooling. This analysis is commonly 
referred to as an adiabatic heat-up. The licensee's analysis 
demonstrates that, as of September 26, 2013, there would be at least 
19.7 hours under adiabatic heat-up conditions before the spent fuel 
cladding would reach a temperature where the potential for a 
significant offsite radiological release could occur. This analysis 
conservatively does not consider the period of time from the initiating 
event causing a loss of SFP water inventory until all cooling means are 
lost.
    The NRC staff has verified DEF's analyses and its calculations. The 
analyses provide reasonable assurance that in granting the requested 
exemptions to DEF, there is no design-basis accident that will result 
in an offsite radiological release exceeding the EPA PAGs at the 
exclusion area boundary. In the unlikely event of a beyond-design-basis 
accident affecting the SFP that results in adiabatic heat-up conditions 
(i.e., a complete loss of heat removal via all modes of heat transfer), 
the NRC staff has reviewed and verified that there will be at least 
19.7 hours available before an offsite release might occur and, 
therefore, at least 19.7 hours to initiate appropriate mitigating 
actions to restore a means of heat removal to the spent fuel. If a 
radiological release were projected to occur under this unlikely 
scenario, a minimum of 10 hours is considered sufficient time for 
offsite authorities to implement protective actions using a CEMP 
approach to protect the health and safety of the public.
    The NRC staff reviewed the licensee's justification for the 
requested exemptions against the criteria in 10 CFR 50.12(a) and the 
bases for prior EP exemption request approvals, as discussed above. The 
staff determined, as described below, that the criteria in 10 CFR 
50.12(a) are met, and that the exemptions should be granted. Assessment 
of the DEF EP exemptions is described in SECY-14-0118, ``Request by 
Duke Energy Florida, Inc., for Exemptions from Certain Emergency 
Planning Requirements,'' dated October 29, 2014 (ADAMS Accession No. 
ML14219A444). The Commission approved the NRC staff's intention to 
grant the exemptions in the SRM to SECY-14-0118, dated December 30, 
2014 (ADAMS Accession No. ML14364A111). Descriptions of the specific 
exemptions requested by DEF and the NRC staff's basis for granting each 
exemption are provided in SECY-14-0118 and summarized in a table at the 
end of this document. The staff's detailed review and technical basis 
for the approval of the specific EP exemptions are provided in the NRC 
staff's safety evaluation enclosed in an NRC letter dated March 30, 
2015 (ADAMS Accession No. ML15058A906).

A. Authorized by Law

    The licensee has proposed exemptions from certain EP requirements 
in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR 50, appendix E, 
section IV, that would allow DEF to revise the CR-3 Emergency Plan to 
reflect the permanently shutdown and defueled condition of the station. 
As stated above, in accordance with 10 CFR 50.12, the Commission may, 
upon application by any interested person or upon its own initiative, 
grant exemptions from the requirements of 10 CFR part 50. The NRC staff 
has determined that granting of the licensee's proposed exemptions will 
not result in a violation of the Atomic Energy Act of 1954, as amended, 
or the NRC's regulations. Therefore, the exemptions are authorized by 
law.

B. No Undue Risk to Public Health and Safety

    As stated previously, DEF provided analyses that show the 
radiological consequences of design-basis accidents will not exceed the 
limits of the EPA PAGs at the exclusion area boundary. Therefore, 
formal offsite radiological emergency plans required under 10 CFR part 
50 are no longer needed for protection of the public beyond the 
exclusion area boundary.
    Although very unlikely, there is one postulated beyond-design-basis 
accident that might result in significant offsite radiological 
releases. However, NUREG-1738 confirms that the risk of beyond-design-
basis accidents is greatly reduced at permanently shutdown and defueled 
reactors. The NRC staff's analyses concludes that the event sequences 
important to risk at permanently shutdown and defueled power reactors 
are limited to large earthquakes and cask drop events. For EP 
assessments, this is an important difference relative

[[Page 19361]]

to operating power reactors where typically a large number of different 
sequences make significant contributions to risk. Per NUREG-1738, 
relaxation of offsite EP requirements under 10 CFR part 50 a few months 
after shutdown resulted in only a small change in risk.
    NUREG-1738 further concludes that the change in risk due to 
relaxation of offsite EP requirements is small because the overall risk 
is low, and because even under current EP requirements for operating 
power reactors, EP was judged to have marginal impact on evacuation 
effectiveness in the severe earthquakes that dominate SFP risk. 
Specifically, for ground motion levels that correspond to SFP failure 
in the central and eastern United States, it is expected that 
electrical power would be lost and more than half of the bridges and 
buildings (including those housing communication systems and emergency 
response equipment) would be unsafe even for temporary use within at 
least 10 miles of the plant. This approach is also consistent with 
previous Commission rulings on San Onofre and Diablo Canyon in which 
the Commission found that for those risk-dominant earthquakes that 
cause very severe damage to both the plant and the offsite area, 
emergency response would have marginal benefit because of offsite 
damage. All other sequences including cask drops (for which offsite 
radiological emergency plans are expected to be more effective) are too 
low in likelihood to have a significant impact on risk.
    Therefore, granting exemptions that eliminate the requirements of 
10 CFR part 50 to maintain offsite radiological emergency plans and 
reducing the scope of onsite emergency planning activities will not 
present an undue risk to the public health and safety.

C. Consistent With the Common Defense and Security

    The requested exemptions by DEF only involve EP requirements under 
10 CFR part 50 and will allow DEF to revise the CR-3 Emergency Plan to 
reflect the permanently shutdown and defueled condition of the 
facility. Physical security measures at CR-3 are not affected by the 
requested EP exemptions. The discontinuation of formal offsite 
radiological emergency plans and the reduction in scope of the onsite 
emergency planning activities at CR-3 will not adversely affect DEF's 
ability to physically secure the site or protect special nuclear 
material. Therefore, the proposed exemptions are consistent with common 
defense and security.

D. Special Circumstances

    Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii), 
are present whenever application of the regulation in the particular 
circumstances is not necessary to achieve the underlying purpose of the 
rule. The underlying purpose of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), 
and 10 CFR part 50, appendix E, section IV, is to provide reasonable 
assurance that adequate protective measures can and will be taken in 
the event of a radiological emergency, to establish plume exposure and 
ingestion pathway emergency planning zones for nuclear power plants, 
and to ensure that licensees maintain effective offsite and onsite 
radiological emergency plans. The standards and requirements in these 
regulations were developed by considering the risks associated with 
operation of a power reactor at its licensed full-power level. These 
risks include the potential for a reactor accident with offsite 
radiological dose consequences.
    As discussed previously, because CR-3 is permanently shutdown and 
defueled, there is no longer a risk of offsite radiological release 
from a design-basis accident and the risk of a significant offsite 
radiological release from a beyond-design-basis accident is greatly 
reduced when compared to an operating power reactor. The NRC staff has 
confirmed the reduced risks at CR-3 by comparing the generic risk 
assumptions in the analyses in NUREG-1738 to site specific conditions 
at CR-3 and determined that the risk values in NUREG-1738 bound the 
risks presented by CR-3. Furthermore, the staff has recently concluded 
in NUREG-2161, ``Consequence Study of a Beyond-Design-Basis Earthquake 
Affecting the Spent Fuel Pool for a U.S. Mark I Boiling Water 
Reactor,'' dated September 2014 (ADAMS Accession No. ML14255A365), 
that, consistent with earlier research studies, SFPs are robust 
structures that are likely to withstand severe earthquakes without 
leaking cooling water and potentially uncovering the spent fuel. The 
NUREG-2161 study shows the likelihood of a radiological release from 
spent fuel after the analyzed severe earthquake at the reference plant 
to be about one time in 10 million years or lower.
    The licensee has analyzed site-specific spent fuel air-cooling and 
adiabatic heat-up beyond-design-basis accident scenarios to determine 
the risk of cladding damage, and the time to rapid cladding oxidation. 
The air-cooling analysis shows that as of September 26, 2013, in the 
event of a complete SFP drain down due to a loss of water inventory, 
assuming that natural circulation of air through the spent fuel racks 
was available, the peak fuel clad temperature would remain below 
1049[emsp14][deg]F (565[ordm]C), the temperature at which incipient 
cladding failure may occur. Therefore, in this postulated accident, 
fuel cladding remains intact.
    The beyond-design-basis adiabatic heat-up accident analysis of the 
spent fuel evaluates a postulated condition involving a very unlikely 
scenario where the SFP is drained in such a way that all modes of 
cooling or heat transfer are assumed to be unavailable. DEF analysis of 
this beyond-design-basis accident shows that as of September 26, 2013, 
19.7 hours would be available between the time the fuel is uncovered 
(at which time adiabatic heat-up begins), until the fuel cladding 
reaches a temperature of 1652[emsp14][deg]F (900[ordm]C), the 
temperature associated with rapid cladding oxidation and the potential 
for a significant radiological release.
    Exemptions from the offsite EP requirements in 10 CFR part 50 have 
previously been approved by the NRC when the site-specific analyses 
show that at least 10 hours is available following a loss of SFP 
coolant inventory accident with no air cooling (or other methods of 
removing decay heat) until cladding of the hottest fuel assembly 
reaches the zirconium rapid oxidation temperature. The NRC staff 
concluded in its previously granted exemptions, as it does with the DEF 
requested EP exemptions, that if a minimum of 10 hours is available to 
initiate mitigative actions consistent with plant conditions, or if 
needed, for offsite authorities to implement protective actions using a 
CEMP approach, then formal offsite radiological emergency plans, 
required under 10 CFR part 50, are not necessary at permanently 
shutdown and defueled facilities.
    Additionally, DEF committed to maintaining SFP makeup strategies in 
its letter to the NRC dated May 7, 2014 (ADAMS Accession No. 
ML14139A006). The multiple strategies for providing makeup to the SFP 
include: Using existing plant systems for inventory makeup; supplying 
water through hoses to connections to the existing SFP piping using the 
diesel-driven fire service pump; and using a diesel-driven portable 
pump to take suction from CR-3 intake and discharge canals. These 
strategies will continue to be required as license condition 2.C.(14), 
``Mitigation Strategy License Condition.'' Considering the very low 
probability of beyond-design-basis accidents affecting the SFP, these 
diverse strategies provide

[[Page 19362]]

multiple methods to obtain additional makeup or spray to the SFP before 
the onset of any postulated offsite radiological release.
    For all the reasons stated above, the NRC staff finds that the 
licensee's requested exemptions to meet the underlying purpose of all 
of the standards in 10 CFR 50.47(b), and requirements in 10 CFR 
50.47(c)(2) and 10 CFR part 50, appendix E, acceptably satisfy the 
special circumstances in 10 CFR 50.12(a)(2)(ii) in view of the greatly 
reduced risk of offsite radiological consequences associated with the 
permanently shutdown and defueled state of the CR-3 facility.
    The NRC staff has concluded that the exemptions being granted by 
this action will maintain an acceptable level of emergency preparedness 
at CR-3 and, if needed, that there is reasonable assurance that 
adequate offsite protective measures can and will be taken by State and 
local government agencies using a CEMP approach in the unlikely event 
of a radiological emergency at the CR-3 facility. Since the underlying 
purposes of the rules, as exempted, would continue to be achieved, even 
with the elimination of the requirements under 10 CFR part 50 to 
maintain formal offsite radiological emergency plans and reduction in 
the scope of the onsite emergency planning activities at CR-3, the 
special circumstances required by 10 CFR 50.12(a)(2)(ii) exist.

E. Environmental Considerations

    In accordance with 10 CFR 51.31(a), the Commission has determined 
that the granting of this exemption will not have a significant effect 
on the quality of the human environment as discussed in the NRC staff's 
Finding of No Significant Impact and associated Environmental 
Assessment published March 2, 2015 (80 FR 11233).

IV. Conclusions

    Accordingly, the Commission has determined, pursuant to 10 CFR 
50.12(a), that DEF's request for exemptions from certain EP 
requirements in 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 
50, appendix E, section IV, and as summarized in the table at the end 
of this document, are authorized by law, will not present an undue risk 
to the public health and safety, and are consistent with the common 
defense and security. Also, special circumstances are present. 
Therefore, the Commission hereby grants DEF exemptions from certain EP 
requirements of 10 CFR 50.47(b), 10 CFR 50.47(c)(2), and 10 CFR part 
50, appendix E, section IV, as discussed and evaluated in detail in the 
staff's safety evaluation dated March 30, 2015. The exemptions are 
effective as of March 30, 2015.

    Dated at Rockville, Maryland, this 30th day of March, 2015.

    For the Nuclear Regulatory Commission.

10 CFR 50.47(b)..............  In the Statement of Considerations (SOC)
The NRC is granting             for the final rule for emergency
 exemptions from portions of    planning (EP) requirements for
 the rule language that would   independent spent fuel storage
 otherwise require offsite      installations (ISFSIs) and for monitor
 emergency response plans.      retrievable storage installations (MRS)
                                (60 Federal Register (FR) 32430; June
                                22, 1995), the Commission responded to

                               In a nuclear power reactor's permanently
                                defueled state, the accident risks are
                                more similar to an ISFSI or a MRS than
                                an operating nuclear power plant. The EP
                                program would be similar to that
                                required for an ISFSI under section
                                72.32(a) of 10 CFR when fuel stored in
                                the spent fuel pool (SFP) has more than
                                5 years of decay time and would not
                                change substantially when all the fuel
                                is transferred from the SFP to an onsite
                                ISFSI. Exemptions from offsite EP
                                requirements have previously been
                                approved when the site-specific analyses
                                show that at least 10 hours is available
                                until the hottest fuel assembly reaches
                                900[deg]C from a partial drain-down
                                event without any spent fuel cooling.
                                The technical basis that underlied the
                                approval of the exemption request is
                                based partly on the analysis of a time
                                period that spent fuel stored in the SFP
                                is unlikely to reach the zirconium
                                ignition temperature in less than 10
                                hours. This time period is based on a
                                heat-up calculation, which uses several
                                simplifying assumptions. Some of these
                                assumptions are conservative (adiabatic
                                conditions), while others are non-
                                conservative (no oxidation below
                                900[deg]C). Weighing the conservatisms
                                and non-conservatisms, the NRC staff
                                judges that this calculation reasonably
                                represents conditions, which may occur
                                in the event of an SFP accident. The
                                staff concluded that if 10 hours were
                                available to initiate mitigative
                                actions, or if needed, offsite
                                protective actions using a comprehensive
                                emergency management plan (CEMP), formal
                                offsite radiological emergency plans are
                                not necessary for these permanently

                               As supported by the licensee's SFP
                                analysis, the NRC staff believes an
                                exemption to the requirements for formal
                                offsite radiological emergency plans is
                                justified for a zirconium fire scenario
                                considering the low likelihood of this
                                event together with time available to
                                take mitigative or protective actions
                                between the initiating event and before

                                drained, air cooling will prevent the
                                fuel from reaching the lowest

                                failure may occur (565[deg]C). In the

                                from the reactor vessel.
                               The NRC excluded non-power reactors from
                                the scope of ``hostile action'' at the
                                time of the rulemaking because, as
                                defined in 10 CFR 50.2, a non-power

                                power reactor and a regulatory basis had
                                not been developed to support the
                                inclusion of non-power reactors within
                                the scope of ``hostile action.''
                                Similarly, a decommissioning power
                                reactor or an ISFSI is not a ``nuclear
                                reactor'' as defined in 10 CFR part 50.
                                A decommissioning power reactor also has
                                a low likelihood of a credible accident
                                resulting in radiological releases
                                requiring offsite protective measures.
                                For all of these reasons, the NRC staff
                                concludes that a decommissioning power
                                reactor is not a facility that falls
                                within the scope of ``hostile action.''
                               Similarly, for security, risk insights
                                can be used to determine which targets
                                are important to protect against
                                sabotage. A level of security
                                commensurate with the consequences of a
                                sabotage event is required and is
                                evaluated on a site-specific basis. The
                                severity of the consequences declines as
                                fuel ages and, thereby, removes over
                                time the underlying concern that a
                                sabotage attack could cause offsite
                                radiological consequences.
                               Although, this analysis provides a
                                justification for exempting CR-3 from
                                ``hostile action'' related requirements,
