SUBJECT:
Waterford SES Unit 3 Docket No. 50-382 Request for a Change to the Bases Section of the Waterford 3 Technical Specifications

W3P87-2049 dated August 28, 1987 2.
W3P87-2306 dated December 10, 1987 Gentlemen:
The purpose of this letter is to submit a change to the Waterford 3 Technical Specification Bases Section to describe the design bases for Technical Speci-fication 3.5.2, ECCS Subsystems.
The Emergency Core Cooling System (ECCS) Subsystem Technical Specification is divided into two parts. The first part, Technical Specification 3/4.5.2, is for operational modes 1, 2, and 3 (with RCS temperature greater than or equal to 350 F).
The second part is for operational modes 3 (with RCS temper-ature less than 350 F) and 4.
In 1987 the referenced letters requested that the bounding RCS temperature for Technical Specifications 3.5.2 and 3.5.3 be changed from 350 F to 500 F, and the titles of these Specifications be changed to reflect modes of operation rather than RCS temperature.
During the review, the NRC reviewer commented that the bases for the subject specifications is incomplete in that no dis-cussion of the intent of Technical Specification 3.5.2 is present.
Upon l
further review, LP&L concurs with this comment. The intent of Technical Specification 3.5.2 is to ensure that sufficient emergency core cooling capa-bility is available to mitigate an uncontrolled RCS cooldown while in mode 3 l
I with RCS temperature greater than 500*F.
The proposed change, therefore, is requested to incorpurate this statement in the Technical Specification Bases Section.
