l ATTACHMENT 4 TO AEP:NRC: 1204D Page 1 Regulatory Requirement:

10 CFR 50, Appendix J provides the requirements for primary containment leakage testing for the Cook Nuclear Plant.

J Appendix J requires that a Type A test be performed in conjunction with the shutdown for the 10-year plant inservice inspection.

Effect of Requirement:

The effect of the requirement is to ensure that the primary

~

reactor containment and systems and components penetrating j

conteinment shall not exceed allowable leak rate values as specified in the technical specifications.

Rationale for Regulatory Change:

The performance of a Type A test will not provide assurance of the containment integrity commensurate with the cost of performing the test.

The data history from previous tests and the performance of the Type b and C testing program sill provide reasonable assurance that the containment leakage rates are well within the allowable limits of Appendix J and the Cook Nuclear Plant Technical Specifications. As a result, the deferment of the Type A test by one cycle will not affect the ability to assess the leak tight capability of the containment structure.

Approximate Cost of Requirement:

Historically, the critical path time associated with performin5 a Type A test is between 36 and 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br />.

The labor time savings for performanc>, of the Type A test, including set-up and breakdown is estimated to be approximately $54,000.

Equipment rental and calibration services are estimated to be approximately $56,000.

It is also estimated that approximately 2 manrem of dose can be saved by not performing the Type A test. At an associated cost of $10,000 per manrem, this represents a savings of

$20,000.

Therefore, the total savings in 1995 associated with not nerforming the Type A test is $130,000, not including che costs of replacement power.
