APPENDIX A NOTICE OF VIOLATION Northeast Nuclear Energy Company Docket No. 50-336 Millstone Unit 2 License No. OPR-65 During routine safety inspection from March 22 to May 2, 1988, the following violation was identified in accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C.
Plant Technical Specification 6.8.1.a. requires implementation of written procedures covering the applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33 (February,1978). Section 8.b.1 of Regulatory Guide 1.33 includes procedures for area, portable, and airborne radiation monitor calibration.
Calibration procedure SP-2404BA "Control Room Ventilation Radiation Monitor Calibration," section 7.4 requires in part that the Control Room Ventilation Monitors be exposed to a known gamma flux dose rate on the bottom decade (0.1 to 10.0 mR/hr) and on the top decade or as high as practicable (1.0 to 10.0 R/hr) during calibration.
Contrary to the above, during calibrations performed during December 1986, the recorded test data shows that neither of the Control Room Ventilation Monitors were exposed to a gamma flux dose rate equivalent to the top decade of the monitor. Both monitors were exposed to two points on the bottom decade.
It was also noted that supervisory review of the completed test results failed to identify the test discrepancy.
This is a Severity Level IV violation (Supplement I).
Pursuant to 10 CFR 2.201, Northeast Nuclear Energy Company is hereby required to submit to this office, within thirty days of the date of the letter which trans-mitted this Notice, a written statement or explanation in reply including: (1) the corrective steps taken and the results achieved; (2) corrective steps to be taken to avoid further violations; and (3) the date wFen full compliance will be achieved.
Where good cause is shown, consideration will be given to extending this response time.
