May 31,1985 MEMORANDUM FOR: Thomas M. Novak, Assistant Director for Licensing, DL FROM:
R. Wayne Houston, Assistant Director for Reactor Safety, DSI
SUBJECT:
RIVER BEND STATION: REQUEST FOR EXEMPTION FROM AIR LOCK TESTING REQUIREMENTS OF APPENDIX J In its letter dated May 15, 1985, the applicant has requested an exemption from paragraph III.D.2.(b)(ii) of Appendix J to 10 CFR Part 50. This paragraph requires air lock testing at the end of periods when the containment integrity is not required and the af r lock has been used. Specifically, at the end of such periods, the air lock is to be tested at P, (peak calculated accident pressure).
The applicant proposes to test the air lock seals rather than the air lock at P and to test within 3 days of closin r$quirements of paragraph III.D.2.(b)(g the air lock, instead of the ii).
The applicant's justification for the exemption is that Appendix J paragraph III.D.2.(b)(iii) allows testing of air lock seals at P within 3 days of closing when containment integrity is required instead,of overall air lock testing at P,.
In this regard, we note thiii the requirements of paragraph III.D.2.(b)(iii)
C were introduced into Appendix J to avoid multiple. testing of the air lock when the air lcok is.used frequently and when containment integrity is required.
Furthermore, during the period when containment integrity is required, the use of the air lock follows stringent administrative procedures by authorized personnel. However, during periods when containment integrity is not required, l
frequent use of the air lock with less stringent administrative procedures can occur.
l Therefore, we find the applicant's request for an exemption from the requirements l
of paragraph III.D.Z(b)(ii) to be unacceptable and should be denied.
