SUBJECT:
COMPLETION OF REVIEW 0F SAFETY INJECTION LINE BREAK ANALYSIS -
JOSEPH M. FARLEY NUCLEAR PLANT'(FARLEY), UNITS 1 AND'2 (TACS 66983 AND66894)
Dear Mr. Hairston:
In December 1987. Farley, Unit 2, experienced a crack in the 6-inch safety injection.line attached to one of the reactor coolant system cold legs. ' The' generic' aspects of this event ~are incorporated into Bulletin 88-08 to which you have responded. 'In addition to the generic aspects of such an unisolated pipe break, we expressed a concern to your staff regarding the small break r
loss-of-coolant accident (LOCA) analysis of record. Of specific concern was whether the effect of direct spilling of the safety injection flow to the containment had been appropriately modeled in the analysis.
o By letter dated January 14, 1988 you provided an evaluation of this concern.
t l
The evaluation showed that the effect of modeling direct spilling of the safety injection flow would increase fuel peak cladding temperatures by 46*F above I:
that reported in the Final Safety Analysis Report.
1 L
We have completed our review of your evi.luation and have concluded that your l
analysis demonstrates that Farley meets the performance requirements of 10 CFR 50.46. We further conclude that the 46 F error does not represent a significant error, as defined by 10 CFR 40.46(3)(1), in the application of an acceptable LOCA L
