NORTHERN STATES POWER COMPANY Minneapolis, Minnesota 55401 February 7, '.975 Mr. J. G. Teppler, Director Region III Office of Inspection and Enforcement United States Nuclear Regulatory Comission 799 Roosevelt Road Glen Ellyn, Illinois 60137

Dear Mr. Keppler:

lDNTICELLO NUCLEAR GENERATING PIAhT Docket No. 50-263 License No. DPR-22 This letter is submitted in reply to the two apparent violations of AEC requirements identified as items A and B under Enforcement Action in the Summary of Findings section of R0 Inspection Report No. 050-263/74-10. A copy of these items is attached for your reference.

Response to Item A.

The teittporary bypass line around the 102 valve for CRD 46-27 was installed in early June, 1974 Since that time a number of changes to Administrative Control Directives and administrative forms have been incorporated, The Work Request Authoritation (WRA) forms, which are used to initiate, authorite and control work such as the bypass line installation, were revised in late June,1974. The plant directive governing the processing and use of the WRA forms was revised in July, 1974. All of the plant Directives related to design changes, including ACD-7.1, were superseded by Power Production Department directives in November, 1974. These changes include the addition of a blank on the WRA forms which must be signed by the Superintendent of Plant Engineering and Radiation Protection before work involving a design change is allowed to commence. This provides a means for assuring that proper review and approvals are obtained prior to opera-tion of safety-related design changes.

The RO Inspection Report refers in several places to " Approval" by the Operations Commit tee. As a point of clarification, it should be noted that the Committee is only required to reviev and make recommendations; approval is a management function.

2 Response to Item B.

In January, 1975, Administrative Control Directive 4 ACD-4.8, Bypass Control, was revised to incorporate the use of a Jumper Bypass Form. The form has clearly identified spaces for each required signature or initial, including those required to docinent independent verification.

Instructions are printed on the back of the form. The problem has been discussed with the Shift Super-visors.

It is believed that these measures will minimize the probability of a recurrence.

Yours very truly, h
