NORTHERN STATES POWER COMPANY M I N N E A PO LI S. b 'I N N E SOTA 55401 October 31, 1979 Mr. R. F. Heishman, Chief Reactor Operntions and Nuclear Support Branch Region III United States Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, Illinois 60137

Dear Jr. Heishman:

PRAIRIE ISLAND NUCLEAR GENERATING 7 LANT Dockets No. 50-282 and No. 50-306 The following is submitted in response to your request for additional information, IE Bulletin 79-01, dated September 21, 1979:

I~em No. 1 The equipment discussed in IE Circular 78-08 and IE Bulletin 79-01 is listed by component type in the attachel tables. The referenced documentation is available at the plant site and has previously been inspected. See Inspection Reports No. 50-282/78-19 and No. 50-306/78-19.

Item No. 2 Ancillary components such as lubricants, gaskets, hermetic seals, and "0" rings were qualified as part of a major component as indicated in the attached tables. Unqualified subst4tute ancillary components are not utilized.

Splicing materials, tapes, and coatings are included in the tabulated list of equipment along with the qualification documentation reference.

Item No. 3 In responce to IE Circular 78-08, a special Task Force was established to review all pertinent Plant Construction Quality Assurance documents, Motor Lists, Mechanical Components Lists, and Calibration and Maintenance Records.

For electrical cable and splice material, it was necessary to assemble all contra *.or daily work sheets, identify the safety-related items, and determine that prcper qualification documentation existed. For instrumentation, it was necessary for Instrument sad Control Specialists to enter the containment.

and directly observe transmitter sub-component part numbers. nr-fa 9.

NORTHERN STATES POWER COMPANY Mr. R. F. Heishman i October 31, 1979 Page 2 pressurizer pressure transmitters were replaced with qualified devices on an emergency procurement basis due to the plant task force inspection.

Item No. 4 Limit switches of the type described in IE Bulletins 79-01 and 78-04 are used for position indication for valves inside the containment. As a result of IE Bulletin 78-04, qualified "open" limit switches have been installed on all safety-related air-operated valves inside containment.

Limit switches for other valve position indications are not qualified.

Item No. 5 - Response to IE Bulletin 79-OlA Asco solenoids are used in safety-related systems at Prairie Island; howevar, not all valves are required to operate in a LOCA environment.

As a result of TE Circular 78-08, all solenoid valve installations or safety systems were identified and a determination was made on the valve operability requirements. All solenoid valves which were required to be functional in a LOCA environment or which are normally energized during operat.on and thus might fail to vent (close) when de-energized, were replaced with Asco NP-1 valves. The remaining solenoid valves are normally de-energized, are not required to operate in a LOCA environment, and therefore fail-safe in a closed valve positior..

A preventive maintenance program for the newly installed solenoid valves will be established within the time requirement immended by the manufacturer.

Yours very truly, L.
