Revision 1 Report Titles Testin Criteria for Intcetra'ad Leakage Rate Testirg of Primary Containment StruCLures for uclear Power Plants Report Date:
November 1, 1972 Driginating OrgafizaLio:
Bechtel Corporation, San Francisco, Calif.
Reviewed By. 1. B. Fsitti.le, aterials Eingineering Branch,. ABC Directoate of Licensing SUMMIARY OF TCPICALREORTZ Bechtel vresents criterin to first estalish that the contanment has attained tczmperaturc cquilibrium as required by Appendix A of 10 CfR 50 in erems of rate of chanpe of temperature prior to start of test, Criteria are next given for the test duration bcised on stcbilization or decline of lea rate iiith time in turn based on the observed upper bound 95% confidence
-ltmit being less than 75% of the allowable leek rate in no less than six hoiut.
Final criteria require a superimposed known leak rate to verify the test results. The balance of tho topical report presents the calculationsl viethods, instrumnztaLion, crror a-alyses, the Ecchtel computtr progrtsm,
-printouts, and the graph of thQ results of uix ruA and ona HTR imitearated l.eak rate tests.
SULMA O OF REULATORY EVMUATION; The testins criteria presented in this report meet the requirements of
- 10 CFR 50 Appcndix: J, "Reactor Containment leakage Testing for Wate Cooled rower Reactors," and ANSI N45.4-1972, "Ameican National Standard LeAkage Rate Testing of Containment Structures for Nucleaz lleactors."
We cheelCd sample calculations for accuracy nnd comnpleteness and in addition applied standard statistical nlalyses to the data provided and found the Bechtel calculatioral todel and error analyses acceptable.
SUMIARY OF BTGULATORY POSITION1 The Beebtel Topical Report 1W-tOP-1, Rcvisiof 1 dated November 1, 1972, is acceptable for referencing in Safety Analysis Reports.
