UNITED STATES NUCLEAR REGULATORY COMMISSION ENTERGY-OPERATIONS, INC.
MISSISSIPPI POWER &~ LIGHT COMPANY-SYSTEM ENERGY RESOURCES,'INC.
SOUTH MISSIS $1PPI ELECTRIC POWER ASSOCIATION DOCKET NO. 50-416 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Consnission (the Commission) is considering issuance of an amendment to Facility Operating License No. NPF-29 issued to the licensees, for operation of the Grand Gulf Nuclear Station (GGNS),
Unit 1, located in Claiborne County, Mississippi.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendment would change =the Technical Specifications (TS) in accordance with the guidance provided in Generic Letter 87-09, "Section 3.0 and 4.0 of the Standard Technical Specifications (STS) on the
. Applicability of Limiting Conditions for Operation and Surveillance Requirements." The general requirements in TS 3.0.4, applicable to each limitingconditionforoperation(LCO)withinSection3.0,wouldbechanged to' allow operational condition changes without meeting the LC0 requirements provided the remedial actions in the associated action statements do not
. require reactor shutdown if the LCO is not met in a specified time.

ik For those TS which presently have an exception to TS 3.0.4, the exception would be deleted because'the change in TS 3.0.4 would achieve the same effect by
'itself.
For applicable TS which do not presently have an exception to TS 3.0.4, the change in TS 3.0.4 provides increased operational flexibility.
TS 4.0.3 would be changed to allow up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> additional time to run missed surveillance' tests. TS 4.0.4 would be changed to clarify that it does not prevent changing operational conditions to comply with action requirements. The Bases for TS 3.0 and 4.0 would be changed to reflect the changes in the TS.
The proposed action is in accordance with_ the licensee's application for amendment dated August 19, 1988, as revised Novenber 9,1988, December 14, 1988, March 28, 1989, July ~27, 1989, April 6, 1990, and May 23, 1990.
_The Need for the Proposed Action:
The proposed change is needed'to permit operational flexibility-by eliminating unnecessary restrictions to changing from one Operational Condition to another and providing additional time to run surveillances when the specified surveillance interval is inadvertently exceeded.
In addition, the-clarification of TS 4.0.4 is needed to assure that completion of' action requirements will take precedence over surveillance requirements when there is an apparent conflict.

Environmental Impacts of the Proposed Action:
The Commission has completed its evaluation of the proposed change to-TS and has concluded that the proposed TS would provide a level of safety consistent with the updated Final Safety Analysis Report. Therefore, the J
proposed amendment-does not significantly increase the probability or consequences of 6ny accident. The Commission also concludes that the
- amendment involves no significant increase in the amounts and no significant change in the types of any effluents that may be released offrite.and that there should be no significant increase in individual or-cumulative occupational radiation exposure. Accordingly, the Commission concludes'that this proposed action would result in no significant radiological environmental impact.
With regard to potential non-radiological impacts, the proposed change to the 1S involves requirements with respect to installation or use of a facility-component located within the restricted. area as defined 'in 10 CFR Part 20.-
It does not affect non-radiological plant effluents.and has no other environmental impact. Therefore, the C" mission concludes that there are no significant non-radiological environmental impacts associated with the proposed amendment.

4 Alternative to the' Proposed Action:
Since the Con. mission concludeds that there are no significant environmental effects that would result from the proposed action, any
- alternatives with equal or greater environmental impacts need not be evaluated.
c l
The principal alternative would be to deny the requested amendment. This l
L would not reduce erivironmental impacts of plant operation and would result. in reduced operational flexibility.

Alternative Use of Resources:
1 p
This action does not involve the use of any resources not previously considered in the Final Environmental Statements related to the operation-1 l
of Grand-Gulf Nuclear Station, Units 1 and 2, dated September 1981.
1 Acencies and Persons Consulted:
The NRC staff reviewed the licensee's request-and did not consult other
- agencies or persons.
FINDING 0F NO SIGNIFICANT IMPACT The Connission has determined not to prepare an environmental impact statement for-the proposed-license amendment.
Dased upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human.
environment.
