Subject:
Waterford 3 SES Docket No. 50-382 License No. NPF-38 Planned Implementation of Generic Letter 90-00 Gentlemen:
On June 25, 1990, the Nuclear Regulatory Commission (NRC) published' the 3
l subject generic letter (GL) to advise licensees of their position on two pressurized water reactor (PWR) issues.
Two enclosures to the. GL document the' staff position resulting from the resolution of Generic: Issue -70 (GI-70, " Power-Operated Rollef Valve' and Block Valve Rollability"),- and Generic Issue 94 --(GI-94, " Additional 1 Low-Temperature Overpressure Protection for Light-Water Reactors").
The staff requests certain actions to be taken by Entergy to enhance safety at Waterford 3.
The purpose of-this letter is to document Entergy's plan of implementation of GL 00-06; relating the PORVs and block valves and to low-tomperature overpressure protection.
The GL contains two enclosures, each addressing.one _of the--two: generic ^
issues. ' Enclosure A to the GL describes _the staff's position on ' the ' _
resolution of GI-70 addressing PORVs and-block valves.
Waterford 3 does 2
not have PORVs nor block valves.
Therefore, no actions are necessam/ to i
meet requirements identified in Enclosure A..
Enclosure B to the GL~ identifies the staff position on low-temperature--
overpressure protection. -It describes changes made to Technical Specification (TS) =3.4.8.3, Overpressure Protection Systems.
Entergy.
. intends to submit a license amendment request. to modify _ the TS consistent.
with the text supplied with the_ GL enclosure.
Two exceptions already_
identified are described below.

A footnote to Waterford 3-TS 3.4.8.3 will be retained specifying its applicability in Mode 4 to ' temperatures:less than or equal.to 260 F during. inservice-leak and hydrostatic testing with the -
Reactor Coolant System temperature -changes restricted.in accordance with TS 3.4.8.lg.
This was an. amendment granted
- i
- by the NRC on May 30, 1986, to allow compliance with TS requirements to establish the integrity of. all ASME Code Class 1, 2 and 3 components.
2)
The text of the GL TS Surveillance Requirement requires operability of the PORVs to be Tdemonstrated.
Waterford 3 does not have PORVS.
Therefore, - the required snalog channel operation tests and channel calibrations will be unnecessary.
Ilowever, operability of the: Shutdown Cooling System suction line rollef valves should be demonstrated.
Therefore, the modification will require each valve in the suction path between.
the Reactor Coolant System and the shutdown cooling relief valve to be verified as open at least once every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Additionally, Enclosure B is under consideration --by-both Entergy and the Combustion Engineering Owners Group.
Other exceptions may be identified as a result of this review.
The request to modify the TS for low-temperature overpressure protection.
will be made in accordance with the schedule specified in the GL.
If there are any questions or comments on this,. please direct them to. David Rothrock on (504) 739-6693.
Very truly -yours, J
