O Arkansas Power and Light Company Arkansas Nuclear One, Unit No. 2 Docket No. 50-368 NOTICE OF VIOLATION Based on the results of an NRC inspection conducted during the period of February 22 through March 21, 1980, it appears that certain of your activities were not conducted in full compliance with NRC regulations and the conditions of your license (NPF-6), as indicated below:
1.
Technical Specification 6.8.1 requires that, " Written procedures shall be established, implemented, and maintained covering.
. a.
The applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33."
Surveillance Procedure 2304.87, Testing of ESF Time Delay Relays, has been established in accordance with this Technical Specification.
Step 6.3.2.6 and numerous other steps in this procedure state, "If any of the measured values is outside of this range, readjust and verify repeatability in accordance with Supplement I."
This supplement gives instructions for adjusting and retesting the time delay relays and for data recording and calculation of Repeat Accuracy.
Contrary to the above, the licensee failed to adhere to the procedural requirements relating to the use of Supplement I during the performance of Procedure 2304.87, performed under Job Order 5804 on March 13, 1980.
This is an Infraction.
(368/80-05-02) 2.
Technical Specification 4.8.1.1.2.c.2 requirea that each diesel generator shall be verified operable at least once per 18 months by " Verifying that the automatic sequence time delay relays are OPERABLE with tha it.terval between each load block within + 10% of its design interval."
The load block design intervals are obtained from the component start times given in the Table 8.3-1 of the Final Safety Analysis Report.
This table lists component start times as 5 seconds for Service Water (SW) Pumps, 10 seconds for High Pressure Safety Injection (HPSI) Pumps, and 15 seconds for Low Pressure Safety Injection (LPSI) Pumps. Thus, the design intervals are 5 seconds between the SW and HPSI pumps and 5 seconds between the HPSI and LPSI pumps.
Contrary to the above, the as-left data from the Integrated Safeguards Test, 2105.03, performed on February 21, 1980, and from the Testing seenS"N
2 of ESF Time Delay Relays, 2304.87, performed on March 13, 1980, indicate that the interval between 2P89C (HPSI)'and 2P60B (LPSI) was 4.38 seconds and the interval between 2P4B (SW) and 2P89C (HPSI) was 4.23 seconds.
This is an infraction.
