SUBJECT:

TMI ACTION ITEM II.K.3.5, AUTOMATIC TRIP'0F REACTOR i COOLANT PUMPS (TAC NO. 49667) )

1 On. June 28, 1985, Generic Letter (GL) 85-12 was issued to all. applicants and 1 licensees with Westinghouse-designed nuclear steam supply systems. This letter l generically approved the Westinghouse Owner's Group (WOG) reactor coolant pump  !

- (RCP) trip criteria that had been submitted by +.he WOG in response to Generic )

Letter 83-10c and d. GL 85-12 also provided guidance concerning implementation )

of the approved RCP trip criteria. Specifically,Section IV of the generic safety  !

evaluation included in GL 85-12 regt'asted that aaplicants and licensees provide )

plant-specific RCP trip criteria-to supplement the information previously ,

submitted under the WOG generic program. j By letter dated March 5,1987, Connecticut Yankee Atomic Power Company (CYAPC0) I responded to Generic Letter 85-12. CYAPC0 stated that the revised mall break LOCA analysis would resolve this issue and that the analysis indicated that the RCP_ trip was not required. By letter dated August 3,1988, the NRC staff approved your small break LOCA analysis and its conclusion that it is unnecessary to trip the RCPs to assure acceptable emergency core cooling system performance at the Haddam Neck Plant.  ;

CYAPCO, by letter dated August 19, 1988, requested the HRC to close TMI Action  !

Item II.K.3.5 based on the staff's approval of the small break LOCA analysis. 1 l

On this basis, the NRC staff concludes that the RCP trip issE in TMI Action '!

Plant Item II.K.3.5 has been satisfactorily resolved for Haddam Neck. With this- i letter, the staff concludes its efforts on Generic Letter 85-12, Multiplant i Action G-01, TMI Action Plant Item II.K.3.5, and TAC Ho. 49667. If you have any i

. questions regarding this matter, please contact us. j Sincerely, Original signed by 8905170161 090510 PDR ADOCK 05000213 i P PNU Alan B. Wang, Project Manager  !
