Dear Mr. Papanic:

SUBJECT:

EXEMPTION'FROM'THE REQUIREMENTS OF APPENDIX J TO 10'CFR PART 50, PARAGRAPH'III.A.3 The Commission has issued an exemption from certain requirements of Ap'pendix J to-10 CFR Part 50 in response to your letter dated April 17. 1987. The. exemption pertains to certain requirements of 10 CFR Part 50, Appendix J, " Primary Reactor Containment Leakage Testing for Water-Cooled Power Peactors," for all Type A. -

(Containment Integrated Leakage Rate) tests to be' perfonned in accordance with the provisions of the American National Standard (ANSI) N45.4-1972, Leakage Rate Testing of Containment Structures.for Nuclear Reactors March 16, 1972.

This standard requires that containment. leakage rate calculations be performed using either the Point-to-Point method or the Total Time method.

In your letter dated April 17, 1987, you requested an exemption to allow use

.; of the Mass Point method (as provided in ANSI /ANS 56.8-1981). The Consission -l grants the exemption to use the Mass -Point method for calculating containment  :

leakage, with the explicit condition that such tests be conducted with a minimum  !

i test duration of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The exemption is granted until Section III.A.3 of Appendix J is modified.- The exemption applies only to the method of calculating 4 leakage by use of the Mass Point method and not to any other aspects of the tests. ,

The bases for this action are included in the enclosed Exemption. Your letter I has noted that you will propose an amendment to' the Technical Specifications  !

(TSs) to maintain consistency _ between the TSs and the requested exemption. We will respond to the proposed amendment by separate correspondence.~  !

In your letter dated April 1 1987, you requested an exemption to allow use of the mass-plot method (as provided in ANSI /ANS-56.8-1981). The Commission grants the exemption to us the mass-plot method for calculating containment leakage. The exemption }d granted until any final changes in rulemaking of Appendix J become effective. The exemption applies only to the method.of-calculating leakage by se of the mass-plot and not to any other aspects of

.the tests. The bases for this action are included in the enclosed Exemption.
