Docket Nos.-50-282 and 50-306 ,

9 c ,

- Mr. D. M. Musolf, Manager J Nuclear Support Services Northern States Power Company 1 ,;

414 Nicollet Mall Midland Square,.4th Floor-Minneapolis, Minnesota 55401- ,

Dear Mr.'Musolf:

By , letters dated November 4, 1983 and July 6, 1984 you responded'to the requirements of the Salem ATW Item 4.5.2 of Generic Letter 83-28 as related to the Prairie Island Nuclear Generating Plant Unit Nos. 1 and-2. Item 4.5.2 of Generic Letter 83-28 requires licensees of plants not currently designed to permit periodic on-line testing of the reactor trip system to justify not making necessary niodifications to allow such testing.. Your. response confirms that the Prairie Island Units are designed to permit on-line testing of the reactor trip systems and independent testing of the undervoltage and shunt-trip attachments of the reactor trip breakers.

The staff finds that you meet our position of Item 4.5.2 for the Prairie  !

Island Units by your confirming statement on the design capability permitting on-line testing of the reactor trip systems. We, therefore, consider Item  ;

4.5.2 of Generic Letter 83-28 to be closed by this action. ,

This action, however, does not close out TACs 54015.and 54016 associated-with Item 4.5.2 since staff review of Item 4.5.3 which also falls under the work -

scope of these TACs remains to be completed. ,

Sincerely,

/sI Dominic C. Dilanni Project Manager Project Directorate #1 Division of PWR Licensing-A
