Schwencer, Chief Licensing Branch No. 2 Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Dear Mr. Schwencer:

Subject:

NUCLEAR PROJECT NO. 2 SAFETY EVALUATION REPORT (NUREG-0892)

CONFIRMATORY ISSUES (9) FUEL ROD MECHANICAL FRACTURING, AND (10) FUEL ASSEMBLY STRUCTURAL DAMAGE FROM EXTERNAL SOURCES; CLOSURE OF The Licensing Review Group (LRG) generic response to the subject issues, NEDE-21175-3-P, was submitted to the NRC in July, 1982. Subsequent correspondence and meetings lead to a final meeting with the staff on June 10, 1983, at the generic response was accepted. Additionally, it was agreed that whichplant specific closure would be contingent on a plant unique assessment of vertical displacement and combined loads. The attached table, to be submitted in FSAR Amendment No. 32, provides these values. With this submittal NUREG-0892 confirmatory issues (9) and (10) are closed.

Should you have any further questions, please contact Mr. P. L. Powell, WNP-2 L'icensing.

Very truly yours, c~= S4~~
