Monticello Nuclear Generating Plant Response to Re. quest for Additional Information Regarding ISI Relief Recuest No. 8 i Requested Information ,

i The licensee must state the specific paragraph of the regulations (10 CFR 50.55e) under which the request is submitted and provide supportingjustification as discussed below.

Monticello Response 5 The specific paragraph of the regulation used as a basis for the relief request is 10 CFR 50.55a(a) (3) (ii) which states-1 Compliance with the speci6ed requirements of this section would result in hardship or l unusual difficulty without a compensating increase in the level of quality and safety, i l

l The existing calibration blocks, although not possessing the full documentation currently required by ASME Code Section V Article 4 or Section XI, Appendix lli, are acceptable. Existing records l l Indicate they were fabricated from the appropriate P-number grouping material, thereby providing i l adequate assurance that the blocks will establish the proper ultrasonic calibration and sensitivity.  ;

i Purchasing new calibration blocks would be an unnecessary expense that would not result in an ,

increase in the level of quality or safety, and is therefore imprudent. j l

Any new calibration blocks will be obtained with the documentation necessary to demonstrate  ;

compliance with the material specification requirements. [
