NPPD Response to IE Inspection Report 50-298/79-03

Dear Mr. Se3 frit:

This letter is written in response to the letter dated >brch 7, 1979 transmitting IE Inspection Report 50-298/79-03 which indicated that certain of our activities were not conducted in full compliance with NRC re qu i r em e n'.s .

Statement of Deficiency Technical Specificat ions 6. 3.1 and 6. 3. 3 require that detailed written procedures be used for maintenance of systers and components that could have an affect on nuclear sa fety. Cooper Nuclear Station Maintenance Procedure 7.5.4 and ISC Calibration Procedure 7.5.4.2 require that ISC shop test equipment be periodically calibrated ag tinst a bench standard.

Contrary to the above, during the December 1978 calibration of the I&C shop pneumatic calibrator, IS-2529, a bench sta.id m was not used.

This item is a deficiency.

Discussion During the December 1978 calibration of pneumatic calibrator IS-2529, dif ficul ty was experienced in getting good data due to error in reading the canometer 15-1753. In accordance with procedure 7.5.4.2, the I&C Supervisor approved replacing the spec ified bench standard with a com-parable calibrated precision test gauge. k'e believe that the replace-ment gauge was an acceptable substitute and provided for an accurate calibration.

Mr. K. 'eyfrit March 979 Page 2.

Corrective Steps Which Have Been Taken and the Results Achieved Instrument IS-2529 has been sent to the nanufacturer for calibration check and repair if required. IS-2529 was found to be within the t.1%

full scale tolerance specified by procedure 7.5.3.2.

Corrective Steps Which Will be Taken to Avoid Further Noncompliance We are presently obtaining information to purchase a low range dead weight tester to be used as a bench standard for IS-2529 instead of the mercury canometer.

Date When Full Cocpliance Will be Achieved Since procedure 7.5.4.2 states "the specified bench standard can be replaced by a comparable calibrated precis ion test gauge upon approval of the I&C Supervisor", we believe that CNS has been in compliance with 7.5.4.2.

Should you have any questions concerning this matter, please contact me.

Sincerely, M
