Subject:

Follow-up questions on LAR (TAC No. ME3421)

Billy, The following email was sent to you on June 28, 2010, and inadvertently did not get into our ADAMS system. The RAI is being resent to you so that it can be put into the system. Entergy has already provided the responses to the questions here and need not take any further action.

Thanks Kaly Plant: Waterford Steam Electric Station, Unit 3 Docket No.: 50/382 Subject Follow-up questions on your supplement dated June 8, 2010 on the LAR, Addition of Isolation Valves to TS Table 3.4-1 TAC Nos.: ME3418 SUNSI Review Done: Yes. Publicly Available, Normal Release, Non-sensitive, From: N. Kalyanam To: W. Steelman

Billy, By letter dated February 22, 2010, as supplemented by letter dated June 8, 2010, Entergy Operations, Inc. (Entergy) made application to amend the Technical Specifications (TS) of the Waterford Steam Electric Station, Unit 3 (Waterford 3).

The proposed amendment adds valve SI-4052A (Reactor Coolant Loop 2, Shutdown Cooling Suction, Inside Containment Bypass Isolation) and valve SI-4052B ((Reactor Coolant Loop 1, Shutdown Cooling Suction, Inside Containment Bypass Isolation) to Technical Specification Table 3.4-1. The purpose of this line is to equalize the shutdown cooling system pressure down stream of valve SI-405A (Reactor Coolant Loop 2, Shutdown Cooling Suction Inside Containment Isolation) and valve SI-405B

((Reactor Coolant Loop 1, Shutdown Cooling Suction Inside Containment Isolation).

After an initial review, the NRC staff has the following 2 comments on your response dated June 8, 2010, to RAI on subject LAR.

The staff requests you to provide required additional information as soon as possible, but within 30 days of the receipt of this request.

Thanks Kaly REQUEST FOR ADDITIONAL INFORMATION ENTERGY OPERATIONS, INC.

1) RAI 6.b response - We need a summary of the licensees EQ calculation. All design information has to be completed before we can review the application.
2) RAI 7 - The licensee needs to provide a protective coordination curve that shows the penetration, loads, and cables are protected by the fuses/breakers.
