NOTICE OF VIOLATION Southern Nuclear Operating Company Docket Nos.-
50-348 and 50-364 Farley Nuclear Plant. Units 1 and 2 License Nos.
NPF-2 and NPF-8 During a NRC inspection conducted on September 1 through October 12. 1996, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions." NUREG-1600, the violation is listed below:
Technical Specifications (TS) 6.8.1.a requires that applicable written procedures recommended in Appendix A of Regulatory Guide 1.33. Revision
- 2. dated February 1978, shall be established, implemented, and maintained.
Regulatory Guide 1.33. Appendix A. Sections 3.s(2)(a) and 3.n recommends procedures for startup, operation and shutdown of emergency power sources (e.g.. diesel generators) and the Chemical and Volume Control System (including Letdown / Purification System).
Contrary to the above, non-licensed system operators (50) in two separate events failed to properly implement applicable system o)erating procedures (SOP) as written, resulting in mispositioned valves t1at adversely affected operability of the 1B emergency diesel generator (EDG) and initiated two plant transients.
These events were as follows:
On August 23. 1996, two valves (Transfer Header To Storage Tank valve 0$YS2V524 and Manual Pump Discharge To Transfer Header valve 529A) in the IB EDG fuel oil transfer system were inadvertently left open after operators completed refilling the 1B fuel oil storage tank (FOST).
Step 4.8.13 and 4.8.14 of FNP-0-SOP-42.0.
Diesel Generator Fuel Oil Storage And Transfer System required that both valves be closed once fuel oil transfer was complete.
On August 27, 1996, the licensee discovered both valves open and concluded that makeup of fuel oil from the 1B FOST to the IB EDG day tank would not have been possible during the intervening time.
On October 8. 1996, a S0 mispositioned two valves on two separate occasions while attempting to fluff the 2B mixed bed demineralizer in accordance with FNP-2-50P-50.4. Demineralizer Resin Removal And Addition.
During the first incident, while performing Step 4.5.1.3 of S0P-50.4 which required closing demineralizer outlet valve V167B. the 50 inadvertently operated valve V167A and partially closed the valve.
This initiated an overpressure transient of the letdown line.
Shortly afterwards, the 50 proceeded to Step 4.5.1.5 which directed him to open demineralizer Johnson screen outlet valve V1618.
However, the S0 misread the I
procedure and selected V161A, which he opened.
This caused a significant loss of inventory from the volume control tank.
This is a Severity Level IV violation (Supplement I).
