O NUCLEAR REGULATORY COMMIS3!ON REGloN lit 799 ROOSEVELT RO AD CLEN ELLYN, ILLINOl5 40137 December 9, 1976 K. V. Seyfrit, Chief, Reactor Technical Assistance Branch Office of Inspection and Enforcement, Headquarters THRU G. Fiorelli, Chief, Reactor Operations and uclear Support Branch LEAK TESTING OF CONTAINMENT EQUIPMENT HATCH During the review of the Davis-Besse program, it was determined that there were no regulatory requirements for the openings that occur subsequent to the integrated containment leak rate tests. The licensee's FSAR does state that a local leak rate test will be performed following each opening but no acceptance criteria is provided.
(See attached memo from R. D. Martin.)
A review of the Technical Specifications for Point Beach 1/2, Zion 1/2, Prarie Island 1/2, and D. C. Cook indicates that only the Point Beach 1/2 Technical Specifications require the testing following the opening of the equipment hatch. The remaining Technical Specifications are mute on this point.
Appendix J also does not address the requirement to test following each opening unless you were to consider the opening a modification or replace-ment of the component as defined in Section IV A of Appendix J which appears to be stretching the point.
Since the seal of the equipment hatch could be a significant leakage path if they were damaged during closure, it is requested that I and E initiate action to modify the provisions of Appendix J to include the requirement for testing following each opening.
If the equipment hatch does not have provisions'for pressurizing between the seals, Appendix J should require a Class A test following each opening.
Because of the potential time span required in modifying Appendix J it is recommended that in the interim an I and E circular should be distributed to all facilities having equipment hatches.
for your use.
