$r'ehr'c$e*ct the southem electnc system April 22, 1996 Docket No.: 50-364 10 CFR 50.90 U.S. Nuclear Regulatory Commission ATTN.: Document Control Desk Washington, D.C. 20555 Joseph M. Farley Nuclear Plant - Unit 2 L* Tubesheet Region Plugging Criterion Ladies and Gentlemen:
In accordance with the provisions of 10 CFR 50.90, Southern Nuclear Operating Company (SNC) hereby proposes changes to the Joseph M. Farley Nuclear Plant (FNP) Unit 2 Technical Specifications concerning L* Tubesheet Region Plugging Criterion. FNP, Unit 2, currently operates with an F* tubesheet region plugging criterion. The F* criterion was approved in amendment 64 to the Unit 2 Technical Specifications in an NRC letter dated September 21, 1987. However, as eddy current technology evolves, more accurate methods are available to ensure the structural integrity of steam generator tubes. Consequently, an L* tubesheet plugging criterion has been developed.
. L' allows a steam generator tube to remain in service with bands of axial degradation in the tube sheet region provided sufficient non-degraded tubing remains to satisfy regulatory guidance concerning structural and leakage integrity. This submittal is similar to a previously i
approved V. C. Summer nuclear plant submittal.
l Approval of the amendment is requested by October 1,1996, in order to allow use during the l
upcoming Unit 2 steam generator inspections. SNC has determined that the proposed license amendment will not significantly increase the amount of any effluent that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. SNC willimplement the proposed license amendment within 30 days of NRC issuance. contains a Significant Hazards Consideration analysis. Attachment 2 provides i~
page change instructions and revised TS and TS bases. The technical specification pages are based on approval of the alternate repair criteria for outside diar'neter stress corrosion cracking at tube support plate intersections. Attachment 3 provides corres'ponding marked-up existing
. TS and TS bases pages. Attachment 4 contains the technical basis'for the L* criterion.
