Docket No. 50-458 May 13, 1994 Entergy Operations, Inc.
River Bend Station ATTN: Mr. John R. McGaha, Jr.
Vice President Operations Post Office Box 220 St. Francisville, Louisiana 70775
Dear Mr. McGaha:
SUBJECT:
RIVER BEND STATION - CHANGES TO THE ASIATIC CLAM CONTROL PROGRAM (TAC NO. M88672)
Technical Specification 6.8.4.d for the River Bend Station states that a Biofouling Prevention and Detection program must be established, implemented, and maintained to prevent biofouling of safety-related equipment.
In addition, this specification states that changes to this program must be submitted to and approved by the NRC (both the Region and NRR) prior to j
implementation.
River Bend Station implements this requirement through the Asiatic Clam Control Program (ACCP).
Your letter of January 14, 1994 (RBG-39896),
requested changes in this program to delete the current requirements to:
sample sediments in the intake embayment and cooling tower basins, sample the clarifier influent and effluent, and inspect and monitor safety-related heat exchangers.
These changes were requested based on the fact that, following conversion of the service water system to a closed-cycle system during the last refueling outage, Mississippi River water is no longer the source of makeup water for the service water system. Also, operating experience gained since the conversion shows no evidence of further clam infestation.
The staff has completed its review of your request.
Based on our determination that the proposed modifications to the Biofouling Prevention and Detection Program do not prevent it from performing its stated function, we find the proposed change acceptable.
The Region IV Office has concurred in this finding. Our Safety Evaluation is enclosed.
