APPENDIX A NOTICE OF VIOLATION Florida Power Corporation License No. DPR-72 Crystal River Unic 3 Based on the NRC inspection August 5-9, 1979, certain of your activities were apparently not conducted in full compliance with NRC requirements as indicated below. These items have been categorized as described in correspondence to you dated December 31, 1974.
A.
As required by Technical Specification 3.1.3.4, individual safety and regulating rod drop times from the fully withdrawn position shall be verified to be less than or equal to 1.66 seconds from power interruption at the control rod drive breakers to 3/4 insertion (25 percent position) prior to proceeding to Mode 1 and 2.
Contrary to the above, Mode 2 was entered on July 29, 1979, although rod drop data, obtained on July 27, 1979 could not be verified to meet the 1.66 second time requirement, since no timing marks appeared on the oscillograph paper used in the measurements.
Alternate verification of the acceptability of rod drop time results was not performed until August 8,13 and 14,1979.
This is an infraction.
B.
As required by Technical Specification 6.8.1, as implemented by the Crystal River Plant Operating Quality Assurance Manual Control document AI-400, written procedures shall be established, implemented, maintained and followed step-by-step.
Contrary to the above, on July 2/,1979, the reactor coolant loop RID normalization constants, as calculated by the IBM-5100 RTD Normalization Routine, were not input into the IBM-5100 Heat Balance 11 routine as required by step 12, Enclosure 1 of PT-100 prior to the first F 4t balance taken at approximately 15 percent FP per PT-120.
The constants were not properly input into the computer software until August 6, 1979 at a power level of 75 percent.
This is an infraction.
