Docket No. 50-348 50-364 U. S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 Joseph M. Farley Nuciear Plant Steam Generator Tuh support Plate Alternate Pluaqina Criteria

Dear Sirs:

In a letter dated January 29, 1992, the NRC Staff indicated to Southern Nuclear Operating Company that the stuam generator tube support plate alternate plugging criteria amendment would not be approved prior to the upcoming Unit 2 Spring 1992 outage. At that time, the Staff indicated that a more conservative submittal might be approved on a one cycle basis. On February 6, 1992, Southern Nuclear met with the NRC Staff to discuss a proposed interim plugging criteria and to respond to Staff questions concerning the alternate plugging criteria.

Attached are copies of Westinghouse slides used in presentations at that meeting. These copies are provided as:

1. WCAP-13221 - Steam Generator Tube Alternate Pluggiag Criteria Presentation Materials (Proprietary).

2. WCAP-13222 - Steam Generator Tute Alternate Plugging Criteria Presentation Materials (Non-Proprietary).

As the Staff requested, the voltage / burst and voltage / leakage correlations for 3/4 inch tubes are being compiled into a separate WCAP. Included in that WCAP is one method which could be used to combine the 3/4 inch and 7/8 inch tube data. This methodology is not necessarily the most correct manner to combine the data.

Unfortunately, time constraints have precluded further evaluation of the data. This WCAP will be forwarded to the NRC Staff separately as soon as-it is received from Westinghouse.

Also enclosed are a Westinghouse authorization letter, CAW-92-272, accompanying affidavit, Proprietary Information Notice, and Copyright Notice. As Item 1 contains information proprietary to Westinghouse Electric Corporation, it is supported by an affidavit signed by I
