Office of-Nuclear. Reactor-Regulation-f Charles W. Hehl, Director FROM:
D hision of Reactor Projects-j Region I-
- I PROPOSED TASK It TERFACE REGARDING
SUBJECT:
COMPLIANCE OF MILLSTONE UNIT 2 WITH r
GENERAL DESIGN CRITERION 17 Your assistance is requested in resolving'a concern originally.
l identifled.by an SSFI conducted by the licensee approximately two 1
years ago and subsequently classified as.an allegation by the NRC.
l The technical concern involves the compliance of:M111 stone' Unit 2 with-General Design Criterion Number 17; specifically, a scenario j
wherein a single fault on an onsite bus and eventual loss of the j
- f. t
- (-
Reserve Station Service Transformer (RSST).could'cause the simultaneous disruption of power to both Unit 2l redundant.4ky l!i class IE divisions.- Our preliminary assessment has identified one involving a protective relaying question ~of 1
two issues:
1 breaker coordination; and, the other a licensing question regarding GDC17 acceptability.
The implications -- if true - -
1 are of-such significance that. an. independent. assessment by' the-Enclosed is an' internal Northeast Utilities
.i NRC is warranted.
Li document dated May 2,1991,- containing an independent, third-party analysis of GDC-17 compliance for M111 stone. Unit' 2.
j We would appreciate your prompt attention'to this satter-andial l
preliminary assessment by July f i991: so that, if a significant-i veakness is identified, action can be taken'to ensure that^the.
~
station can mitigate the effects:of alblackout. -The Region I:
l point of contact-is Edward Wenzinger, Chief, Reactor Projects-
.l Branch 4 (FTS 346-5225).- This TIA proposal has been discussed with John Stolt of NRR.
