Narrative

Report for LER 50-366/1980-155 Gn 11-7-80, with Unit 2 it cold shutdown, a local leak rate test, per procedure HNP-2-3952, " Primary Containment Periodic performed on the RhR Type B and Type C Leakage Tests," was oest line isol,ation valve 2E11-F024B and the condensate drain isolation valve 2B21-F016.

On 11 8 0',

t h e LLRT coordinator reviewed the test data sheets and determined that both valve eriteria,, The RRR test l'eakages exceeded specified acceptance n line isolation valve 2E11-F024B leaka'ge of 6027 accci-wou1dl 3

have caused that t oru s'y water valves specified by 10CFR50

(')

criteria for all section III.C.3 to be exceeded.

The 200 acem leakage of the condensate drain isolation valve 2B21-F016 was such that the

.009 La (544 acem) overall allowable leakage limit for bypass specified by Tech Specs 3.6.1.2.B.2 would path penetration as see LER repetitive occurrence have been exceeded.

This is a 50-366/1980-154.

There were no effects on public health or safety due to this event.

The cause of the leakages is unknown at present.

Investiga-tion is underway; an update report will be submitted.

The valves will be repaired prior to startup.
