Docket No. 50-289 MEMORANDUM FOR:
K. V. Seyfrit, Chief, Technical Assistance Branch IE:HQ THRU:
Cpje-E. J. Brunner, Chief, Reactor Operations and Nuclear f Support Branch, Region I FROM:
E. C. McCabe, Jr., Chief, Nuclear Support Section No.1, Reactor Operations and Nuclear Support Branch SUBJECT:
THREE MILE ISLAND 1 PERIODIC CILRT SCHEDULE (AITS F14545Hl)
Reference:
Inspection 50-289/77-11 Section III.A.6.(a) of Appendix J to 10 CFR 50 states that:
"If any periodic Type A test fails to meet thc applicable acceptance criteria in III.A.5.(b), the test schedule applicable to subsequent Type A tests will be reviewed and approved by the Commission".
Detail 8.a of the referenced report describes the initial failure of the first periodic Type A test (CILRT) at Three Mile Island-1 on April,16 and April, 17, 1977 The failure appears to be due to packing and fitting leaks corrected during the two day period.
Definitive analysis was precluded by repair of the leaks without prior local leak rate measurement and significant diurnal variations in the measured cor.tain-ment leak rate. To provide continued assurance of containment accept-ability between Type A tests, Region I recommends that either the inter-val between Type A tests be shortened or the Three Mile Island Type B and C testing program be upgraded to assure regular measurement and correction of possible leakage paths of the types identified during this and subsequent Type A tests. Also, this Type A test failure needs consideration when the exemptions from Appendix J, that this licensee has requested, are evaluated by the NRC.
