DPR-58 IE REPORT 50-315/80-16 Mr. James G. Keppler, Regional Director U.
S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region III
~ Glen Ellyn, Illinois 60137
Dear Mr. Keppler:
This letter responds to Mr. R.
F. Heishman's letter of November 24, 1980 which we received on November 26, 1980 and which transmitted to us IE Report No. 50-315/80-16.
We provide below our response to the Notice of Violation attached as Appendix A to Mr. Heishman's letter.
Res onse to the Notice of Violation The reported deficiency was due to a failure of the performance engineer to write a temporary change sheet to procedure No.
12-THP 6040 PER.
- 020, Rev. 2, which would have waived the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> calibration require-ment under Step 3.1.
The deficiency does not represent failure to perform a needed calibration, since a calibration had been performed under cali-bration procedures for steam generator mismatch protection just one month
- earlier, on September 15, 1980 at the 18 month recalibration frequency re-quired by Technical Specifications.
In addition, the thermal power measure-ment was being performed during the testing part of the startup period after the refueling outage
- and, the instrument in question had seen only one month's service since its September 15 calibration.
Hence, there was rea-son to believe that the accuracy of the thermal power measurement would be acceptable under existing calibration procedures, and that a recalibration of the instrument was unnecessary.
