SUBJECT:

James A. FitzPatrick Nuclear Power Plant Docket No. 50-333 Proposed Change to the Technical Specifications Regarding Augmented inservice inspection of Main Steam and Feedwater '

Piping Welds (JPTS-89.01,3} ,

Dear Sir:

This application for an amendment to the James A. FitzPatrick Technical Specifications deletes the augmented inservice inspection (ISI) requirements imposed on the main steam and feedwater piping welds. Specification 4.6.F.2 requires 100%

inspection of these welds every ISI interval. This requirement was imposed by the Atomic Energy Commission in 1972, during their review of the Authority's application to - .

operate the Fitzpatrick plant, because it was not practicable to backfit pipe whip restraints on the main steam and feedwater piping inside the drywell. During future ISI intervals,25% of the piping welds will be examined in accordance with the requirements of 10 CFR 50.55a.

1 The proposed changes are based on leak-before break technology, as allowed by .

General Design Criterion 4 in 10 CFR 50 Appendix A, to eliminate the dynamic effect of pipe ruptures from the piping design bases. A leak before-break evaluation has been performed for the Authority by Structural Integrity Associates. A report of this evaluation, entitled " Evaluation of Leak Before Break for Feedwater and Main Steam Piping Inside Containment at the James A. Fitzpatrick Nuclear Power Plant," is enclosed as Attachment Ill. This evaluation concludes that the main steam and feedwater piping systems comply with the general criteria of NUREG 1061, Volume 3 and that augmented inservice inspections of weld locations which are unrestrained against postulated pipe :

breaks are not necessary.

The Authority plans to implement the reduced inspection frequency during the 1990 I refueling outage currently scheduled to start in March. A significant reduction in

)

occupational radiation exposures will be realized if this proposed amendment is approved before the start of the outage.

Specification 4.6 F.2, " Structural Integrity," and associated Bases on pages 144 and 153 are deleted by this amendment.
