NUCLEAR REGULATORY COMMISSION
[Docket No. 50-368]
Entergy Operations, Incorporated; Notice of Consideration of
Issuance of Amendment to Facility Operating License, Proposed No
Significant Hazards Consideration Determination, and Opportunity for a
Hearing
The U.S. Nuclear Regulatory Commission (the Commission, NRC) is
considering issuance of an amendment to Facility Operating License No.
NFP-6, issued to Entergy Operations Incorporated (the licensee), for
operation of Arkansas Nuclear One Unit 2 (ANO-2), located in Pope
county.
The proposed amendment would define spent fuel loading restrictions
for the Holtec International HI-STORM 100 Cask System Multi-Purpose
Canister (MPC)-32. The licensee will be removing spent fuel from the
spent fuel pool and placing it in dry storage as early as September
2005. This activity will restore the full-core offload capability at
ANO-2.
The licensee believed that the calculation that considered the
requirements of 10 CFR 50.68 for loading/unloading an MPC-32 met the
criteria of 10 CFR 50.59 and 10 CFR 50.36, and did not require NRC
review and approval. However, based on Regulatory Information Summary
(RIS) 2005-05, ``Regulatory Issues Regarding Criticality Analyses for
Spent Fuel Pools and Independent Spent Fuel Storage Installations,''
the licensee submitted a pre-application letter to the NRC outlining
the plans to submit a non-exigent technical specification (TS) change
and justification for continued operations without prior NRC approval
based on guidance contained in Administrative Letter 98-10,
``Dispositioning of Technical Specifications that are Insufficient to
Assure Plant Safety,'' and Generic Letter 91-18, ``Information to
Licensees Regarding Two NRC Inspection Manual Sections on Resolution of
Degraded and Nonconforming Conditions and on Operabiltiy.'' In a
teleconference between the licensee and the NRC staff held on July 19,
2005, the NRC stated that it did not believe ANO-2 was in compliance
with 10 CFR 50.68 and, therefore, the proposed change required NRC
approval prior to proceeding with cask loading activities.
Before issuance of the proposed license amendment, the Commission
will have made findings required by the Atomic Energy Act of 1954, as
amended (the Act) and the Commission's regulations.
Pursuant to 10 CFR 50.91(a)(6) for amendments to be granted under
exigent circumstances, the NRC staff must determine that the amendment
request involves no significant hazards consideration. Under the
Commission's regulations in 10 CFR 50.92, this means that operation of
the facility in accordance with the proposed amendment would not (1)
involve a significant increase in the probability or consequences of an
accident previously evaluated; or (2) create the possibility of a new
or different kind of accident from any accident previously evaluated;
or (3) involve a significant reduction in a margin of safety. As
required by 10 CFR 50.91(a), the licensee has provided its analysis of
the issue of no significant hazards consideration, which is presented
below:
1. Does the proposed change involve a significant increase in
the probability or consequences of an accident previously evaluated?
Response: No.
The fuel handling accidents described below can be postulated to
increase reactivity. However, for these accident conditions, the
double contingency principle of ANS N16.1-1975 is applied. This
states that it is unnecessary to assume two unlikely, independent,
concurrent events to ensure protection against a criticality
accident. Thus, for accident conditions, the presence of soluble
boron in the SFP [spent fuel pool] water can be assumed as a
realistic initial condition since its absence would be a second
unlikely event.
Loading/unloading a storage cask in the SFP does not affect the
previously evaluated fuel handling accidents (i.e., criticality
effects) in the SFP. The ANO-2 TS for SFP boron concentration
ensures subcritical conditions in the SFP during fuel movement
activities, whether within the SFP racks or to a storage cask during
normal and accident conditions.
The cask configuration for the storage cask (MPC-32) is
sufficiently similar to spent fuel racks in the SFP as to not induce
new or different spent fuel assembly damage in the unlikely event of
the occurrence of a fuel handling accident during storage cask
loading/unloading activities. The fuel handling accident includes
four drop scenarios (fuel drop horizontally on a cask, fuel drop on
a fuel assembly, fuel drop next to a cask, and a fuel drop on the
cask basket). The same equipment and procedural controls for
controlling fuel within the SFP are utilized when loading/unloading
a storage
[[Page 48197]]
cask. In addition, the postulated fuel handling accidents associated
with loading/unloading a storage cask are bounded by current ANO-2
TS SFP requirements for minimum boron concentration.
Loading/unloading a storage cask will have no impact on the
boron dilution event probability. The same controls for prohibiting
a dilution event during spent fuel movement activities in the SFP
are in use when loading/unloading fuel in a cask located in the cask
pit.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
2. Does the proposed change create the possibility of a new or
different kind of accident from any accident previously evaluated?
Response: No.
The storage casks have the same basic design and control of a
SFP rack. The cask cell walls are thicker than the SFP rack walls;
the outside wall on the cask is thicker than the SFP racks and the
space for mishandling is tighter than around the racks. When the
cask loading pit gate is open and the Technical Specifications are
applicable, the pit is in direct communications with the spent fuel
pool. Boron concentrations and decay heat removal for fuel in the
cask loading pit is controlled in the same manner as it is for fuel
in the spent fuel pool proper.
An accident analysis for the MPC-32 was performed assuming the
same SFP rack accidents that are discussed in the ANO-2 SAR [safety
analysis report]. The ANO-2 TS boron concentration assures that a
subcritical margin is maintained during any postulated accident
condition (i.e., keff [effective neutron multiplication
coefficient] is less than or equal to 0.95).
Therefore, the proposed change does not create the possibility
of a new or different kind of accident from any previously
evaluated.
3. Does the proposed change involve a significant reduction in a
margin of safety?
Response: No.
The ANO-2 TSs require for criticality concerns in the SFP that
keff remain less than or equal to 0.95. For the MPC-32,
the criticality analysis demonstrated that when the ANO-2 TS for SFP
boron concentration is met, a loading restriction is required to
ensure keff remains less than or equal to 0.95. The
proposed change to the ANO-2 TS will ensure the criticality margin
is maintained.
Therefore, the proposed change does not involve a significant
reduction in a margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 10 CFR 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.
The Commission is seeking public comments on this proposed
determination. Any comments received within 14 days after the date of
publication of this notice will be considered in making any final
determination.
Normally, the Commission will not issue the amendment until the
expiration of the 14-day notice period. However, should circumstances
change during the notice period, such that failure to act in a timely
way would result, for example, in derating or shutdown of the facility,
the Commission may issue the license amendment before the expiration of
the 14-day notice period, provided that its final determination is that
the amendment involves no significant hazards consideration. The final
determination will consider all public and State comments received.
Should the Commission take this action, it will publish in the Federal
Register a notice of issuance. The Commission expects that the need to
take this action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D59, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays. Documents may
be examined, and/or copied for a fee, at the NRC's Public Document Room
(PDR), located at One White Flint North, 11555 Rockville Pike (first
floor), Rockville, Maryland.
The filing of requests for hearing and petitions for leave to
intervene is discussed below.
Within 60 days after the date of publication of this notice, the
licensee may file a request for a hearing with respect to issuance of
the amendment to the subject facility operating license and any person
whose interest may be affected by this proceeding and who wishes to
participate as a party in the proceeding must file a written request
for a hearing and a petition for leave to intervene. Requests for a
hearing and a petition for leave to intervene shall be filed in
accordance with the Commission's ``Rules of Practice for Domestic
Licensing Proceedings and Issuance of Orders'' in 10 CFR Part 2.
Interested persons should consult a current copy of 10 CFR 2.309, which
is available at the Commission's PDR, located at One White Flint North,
Public File Area 01F21, 11555 Rockville Pike (first floor), Rockville,
Maryland. Publicly available records will be accessible from the
Agencywide Documents Access and Management System's (ADAMS) Public
Electronic Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/reading-rm/doc-collections/cfr/. If a request for a hearing
or petition for leave to intervene is filed by the above date, the
Commission or a presiding officer designated by the Commission or by
the Chief Administrative Judge of the Atomic Safety and Licensing Board
Panel, will rule on the request and/or petition; and the Secretary or
the Chief Administrative Judge of the Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.309, a petition for leave to intervene
shall set forth with particularity the interest of the petitioner in
the proceeding, and how that interest may be affected by the results of
the proceeding. The petition should specifically explain the reasons
why intervention should be permitted with particular reference to the
following general requirements: (1) The name, address and telephone
number of the requestor or petitioner; (2) the nature of the
requestor's/petitioner's right under the Act to be made a party to the
proceeding; (3) the nature and extent of the requestor's/petitioner's
property, financial, or other interest in the proceeding; and (4) the
possible effect of any decision or order which may be entered in the
proceeding on the requestor's/petitioner's interest. The petition must
also identify the specific contentions which the petitioner/requestor
seeks to have litigated at the proceeding.
Each contention must consist of a specific statement of the issue
of law or fact to be raised or controverted. In addition, the
petitioner/requestor shall provide a brief explanation of the bases for
the contention and a concise statement of the alleged facts or expert
opinion which support the contention and on which the petitioner
intends to rely in proving the contention at the hearing. The
petitioner/requestor must also provide references to those specific
sources and documents of which the petitioner/requestor is aware and on
which the petitioner/requestor intends to rely to establish those facts
or expert opinion. The petitioner/requestor must provide sufficient
information to show that a genuine dispute exists with the applicant on
a material issue of law or fact. Contentions shall be limited to
matters within the scope of the amendment under consideration. The
contention must be one which, if proven, would entitle the petitioner/
requestor to relief. A petitioner/requestor who fails to satisfy these
[[Page 48198]]
requirements with respect to at least one contention will not be
permitted to participate as a party.
Those permitted to intervene become parties to the proceeding,
subject to any limitations in the order granting leave to intervene,
and have the opportunity to participate fully in the conduct of the
hearing.
If a hearing is requested, the Commission will make a final
determination on the issue of no significant hazards consideration. The
final determination will serve to decide when the hearing is held. If
the final determination is that the amendment request involves no
significant hazards consideration, the Commission may issue the
amendment and make it immediately effective, notwithstanding the
request for a hearing. Any hearing held would take place after issuance
of the amendment. If the final determination is that the amendment
request involves a significant hazards consideration, any hearing held
would take place before the issuance of any amendment.
Nontimely requests and/or petitions and contentions will not be
entertained absent a determination by the Commission or the presiding
officer of the Atomic Safety and Licensing Board that the petition,
request and/or the contentions should be granted based on a balancing
of the factors specified in 10 CFR 2.309(c)(1)(i)-(viii).
A request for a hearing or a petition for leave to intervene must
be filed by: (1) First class mail addressed to the Office of the
Secretary of the Commission, U.S. Nuclear Regulatory Commission,
Washington, DC 20555-0001, Attention: Rulemaking and Adjudications
Staff; (2) courier, express mail, and expedited delivery services:
