NOTICE OF VIOLATION IES Utilities Inc.
Duane Arnold Energy Center Docket No. 50-331 License No.
DPR-49 During an NRC inspection conducted on June 6 through July 18,
- 1996, two violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," the violations are listed below:
Part 50.59 of 10 CFR requires, in part, that records of changes to the facility include a written safety evaluation which provides the bases for the determination that the change did not involve an unreviewed safety question.
Contrary to the above, Safety Evaluation No. 95-06, written to support the low emergency service water makeup flow rate to the spent fuel pool (SFP), identified on February 20,
- 1995, assumed a value for heatup rate that was much lower than published data for the SFP configuration in place during refuel outage 13, which began February 23, 1995.
Therefore, the safety evaluation did not provide sufficient bases to determine if the condition may have involved an unreviewed safety question.
(50-331/96005-03)
This is a Severity Level IV violation (Supplement 1).
2.
Part 50 of 10 CFR, Appendix 8, Criterion V, requires in part that activities affecting quality be prescribed by procedures of a type appropriate to the circumstances.
Contrary to the above, the inspectors identified the following deficiencies in plant operating and alarm response procedures that made the procedures not appropriate to the circumstances:
Operating Instruction (OI) 878.8, "NUMAC Rod Worth Minimizer System,"
Revision 9, Section 8.2.4, contained no requirement or steps to be performed to correct a rod substitution value once the "SUBSTITUTE" key had been pushed.
In OI 358, "Reactor Protection System," Revision 26, Attachment 4, "RPS Power Supply Transfer Half-Scram Recovery Checklist,"
contained no requirement or step to reset the carbon bed vault radiation monitor.
Annunciator response procedure for annunciator 1C03A, C-5, "SRV/SV TAILPIPE HI PRES OR HI TEMP," Revision 4, Section 3.6.a, required the operator to reduce reactor power 25X and cycle the affected Safety/relief valve's hand switch.
The step contained no guidance on how to accomplish the 25K downpower.
