NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-321 and 50-366]
Environmental Assessment and Finding of No Significant Impact,
Georgia Power Co., et al.; Edwin I. Hatch Nuclear Plant, Units 1 and 2
This U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of amendments to Facility Operating License Nos.
DPR-57 and NPF-5, issued to Georgia Power Company (GPC or the
licensee), for operation of the Edwin I. Hatch Nuclear Plant, Units 1
and 2, located in Appling County, Georgia.
Environmental Assessment
Identification of the Proposed Action
The proposed amendments will replace the existing Technical
Specifications (TS) in their entirety with the Improved Technical
Specifications (ITS). The proposed action is in accordance with the
licensee's amendment request dated February 25, 1994, and supplemented
July 8, August 8 and August 31, September 23, October 19, and November
1, 1994.
The Need for the Proposed Action
It has been recognized that nuclear safety in all plants would
benefit from improvement and standardization of TS. The ``NRC'' Interim
Policy Statement on Technical Specification Improvements for Nuclear
Power Reactors,'' (52 FR 3788 dated February 6, 1987) and later the
Final Policy Statement, formalized this need. To facilitate the
development of individual ITS, each reactor vendor owners group (OG)
and the NRC staff developed standard technical specifications. For
General Electric (GE) plants, the standard TS (STS) are found in NUREG-
1433, ``Standard Technical Specifications, General Electric Plants,
BWR/4,'' dated September 1992, which formed the basis of the Hatch ITS.
The NRC Committee to Review Generic Requirements (CRGR) reviewed the
STS, made not of its safety merits, and indicated its support of
conversion by operating plants to the STS.
Description of the Proposed Change
The proposed revision to the TS is based on NUREG-1433 and on
guidance provided in the Policy Statement. Its objective is to
completely rewrite, reformat, and streamline the existing TS. Emphasis
is placed on human factors principles to improve clarity and
understanding. The Bases section has been significantly expanded to
clarify and better explain the purpose and foundation of each
specification. In addition to NUREG-1433, portions of the existing TS
were also used as the basis for the ITS. Plant-specific issues (unique
design features, requirements, and operating practices) were discussed
at length with the licensee, and generic matters were discussed with
the licensee, GE, and other OGs.
The proposed changes from the existing TS can be grouped into four
general categories, as follows:
Non-Technical (administrative) changes were intended to make the
ITS easier to use for plant operations personnel. They are purely
editorial in nature or involve the movement or reformat of requirements
without affecting technical content. Every section of the Hatch TS has
undergone these types of changes. In order to ensure consistency, the
NRC staff and GPC have used NUREG-1433 as guidance to reformat and make
other administrative changes.
Relocation of requirements includes items that were in the existing
Hatch TS, but did not meet the criteria set forth in the Policy
Statement for inclusion in TS.
In general, the proposed relocation of items in the Hatch TS to the
Final Safety Analysis Report (FSAR), appropriate plant-specific
programs, procedures, and ITS Bases follows the guidance of the GE STS,
NUREG-1433. Once these items have been relocated by removing them from
the TS to other licensee-controlled documents, the licensee may revise
them under the provisions of 10 CFR 50.59 or other NRC staff-approved
control mechanisms which provide appropriate procedural means to
control changes.
More restrictive requirements are those proposed Hatch ITS items
that are either more conservative than corresponding requirements in
the existing Hatch TS, or are additional restrictions which are not in
the existing Hatch TS, but are contained in NUREG-1433. Examples of
more restrictive requirements include: placing a Limiting Condition of
Operation (LCO) on plant equipment which is not required by the present
TS to be operable; more restrictive requirements to restore inoperable
equipment; and more restrictive surveillance requirements.
Less restrictive requirements are relaxations of corresponding
requirements in the existing Hatch TS which provided little or no
safety benefit or placed unnecessary burden on the licensee. These
relaxations were the result of generic NRC actions or other analyses.
They have been justified on a case-by-case basis for Hatch as described
in the Safety Evaluation to be issued with the license amendment, which
will be noticed in the Federal Register.
Environmental Impacts of the Proposed Action
The Commission has completed its evaluation of the proposed
revision to the TS. Changes which are administrative in nature have
been found to have no effect on technical content of the TS, and are
acceptable. The increased clarity and understanding these changes bring
to the TS are expected to improve the operator's control of the plant
in normal and accident conditions.
Relocation of requirements to other licensee-controlled documents
does not change the requirements themselves. Future changes to these
requirements may be made by the licensee under 10 CFR 50.59 or other
NRC-approved control mechanisms, which assure continued maintenance of
adequate requirements. All such relocations have been found to be in
conformance with the guidelines of NUREG-1433 and the Policy
Statements, and, therefore, to be acceptable.
Changes involving more restrictive requirements have been found to
be acceptable.
Changes involving less restrictive requirements have been reviewed
individually. When requirements have been shown to provide little or no
safety benefit or to place unnecessary burden on the licensee, their
removal from the TS was justified. In most cases, relaxations
previously granted to individual plants on a plant-specific basis were
the result of a generic NRC action, or of agreements reached during
discussions with the OG and found to be acceptable for Hatch. Generic
relaxations contained in NUREG-1433 have also been reviewed by the NRC
staff and have been found to be acceptable.
In summary, the proposed revision to the TS was found to provide
control of plant operations such that reasonable assurance will be
provided that the health and safety of the public will be adequately
protected.
These TS changes will not increase the probability or consequences
of accidents, no changes are being made in the types of an effluent
that may be released offsite, and there is no significant increase in
the allowable individual or cumulative occupational radiation exposure.
Therefore, the Commission concludes that there are no significant
radiological environmental impacts associated with the proposed TS
amendments.
With regard to potential non-radiological impacts, the proposed
amendment involves features located entirely within the restricted
areas as defined in 10 CFR Part 20. It does not affect non-radiological
plant effluent and has no other environmental impact. Therefore, the
Commission concludes that there are no significant non-radiological
environmental impacts associated with the proposed amendment.
Alternatives to the Proposed Action
Since the Commission has concluded there is no measurable
environmental impact associated with the proposed amendments, any
alternatives with equal or greater environmental impact need not be
evaluated. The principal alternative to the amendments would be to deny
the amendment request. Such action would not enhance the protection of
the environment.
Alternative Use of Resources
This action does not involve the use of resources not considered
previously in the Final Environmental Statement for the Hatch Nuclear
Plant, Units 1 and 2.
Agencies and Persons Consulted
The NRC staff consulted with the State of Georgia regarding the
environmental impact of the proposed action.
Finding of No Significant Impact
Based upon the environmental assessment, the Commission concludes
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the Commission has
determined not to prepare an environmental impact statement for the
proposed amendment.
