COT!ENT ON LEAF-BEFORE-BREAK TECHNOLO_GX
Dear Sirs:
We believe that further use of the Leak-Before-Break technology for emergency core cooling systems would in fact R. EDUCE safety assurances and safety benefits.
previous experience har shown that pipe-thinning and deterioration has progressed faster than expected, and in reactor.ystems where thinning was not expected, as the.Surry and Trojan plants demonstrated.
We believe that there are no short cuts t.o safety, that Its present use of leak-before-break technoloey is obviously unreliable, and that mandatory, periodic piping inspections of all pipine should be required at all operating nuclear power plants.
We urce the NRC to use the most conscientious care in helping insure puM1 : safety and henith.
Thank sou.
Sincerely, ggh h t
