Dear Mr. Denton:

Attached are proposed license amendments for McGuire Nuclear Station Facility Operating Licenses NPF-9 (Unit 1) and NPF-17 (Unit 2).

The proposed Technical Specification changes support a planned station modifi-cation, removal of the Resistance Temperature Detector (RTD) Bypass Manifold.

The changes relate to response time and time constants in the calculation of overpower AT and overtemperature aT trip setpoints.

The planned removal of the RTD Bypass Manifold System is being performed to improve plant operation and reduce radiation exposure to workers.

Attachment I is a~ Westinghouse report which describes the RTD Bypass removal modification and the analyses which were performed to support continued operation with the new system. Please note that Attachment I is a Westinghouse Electric Corporation proprietary document, and as such is requested to be withheld from public disclosure. A non-proprietary version is presented as Attachment V.

In addition to this report, there is currently testing being conducted at i McGuire Nuclear Station which is expected to further support the conclusions

(

grio of this report relative to the proposed Technical Specification changes. The results of this testing will be made available upon completion of testing.

.L of Attachment II contains the Technical Specification changes which will be required o)o as a result of the modification Attachment III contains a Technical Justification

. g:c and Safety Analysis, and Attachment IV provides an analysis conforming to the J standards contained in 10 CFR 50.92 as required by 10 CFR 50.91. This analysis g concludes that the proposed amendments would not have adverse safety impact.

I Mr. Harold R. Denton, Director October 29, 1985 Page 2 Please note that because these changes involve hardware modifications which may not occur coincident with staff approval of the amendments, it is necessary to provide both pre- and post-modification values for the affected Technical Specifications.

This request involves one application for amendment to the McGuire's Technical Specifications. Accordingly, pursuant to 10 CFR 170.21, a check for $150.00 is enclosed.

Please note that in order to implement the modification on McGuire Unit I during the upcoming 1986 refueling outage, approval of this amendment will be needed and is requested by February 1,1986.

Please feel free to contact us if you require any additional information.

Very truly yours, d$
