PREDECISIONAL ENFORCEMENT CONFERENCE

Dear Mr. Gambhir:

This refers to the predecisional enforcement conference conducted in the Region IV office on October 7,1997. This conference was convened to discuss apparent violations related to disabling the containment spray system for a period of about 12.5 hours on August 21, 1997, when an operator erroneously placed the control switches for the two containment spray header valves in the " OVERRIDE" position during a surveillance test. This meeting contributed to a better understanding of the events that led to the apparent violations in question and of the corrective actions the Omaha Public Power District has taken and plans to take to prevent recurrence of similar events. During this open meeting, a closed session was held to discuss private plant personnel information. This session lasted approximately 15 minutes, in accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this ictter will be placed in the NRC's Public Document Room. Should you have any questions concerning this matter, we will be pleased to discuss them with you. Sincerely, ( O Thomas P. Gwynn Dir or Division of Reactor je t Docket No.: 50-285 License No.: DPR-40 9710160025 971014 gaa ^=ck **gg5 Illlllll!EIlIlllJillll!Il ]

i APPARENT VIOLATION i 1. Technical Specification 5.8.1, requires that written procedures and administrative policies be established, implemented and maintained that meet or exceed the minimum requirements of Sections 5.1 and 5.3 of ANSI N18.7-1972 and Appendix A of Regulatory Guide 1.33. Regulatory Guide 1.33, Appendix A, Section 3.f(4) requires procedures for startup, operation, and shutdown of containment cooling systems. Procedure OP ST-SI 3008, " Safety injection and Containment Spray Pump Inservice Test and Valve Exercise Test," Revision 19, established, in part, written procedures for testing the containment spray system. Step 7.10 required that Containment Spray Valves HCV 344 and HCV-345 be placed in the closed position and that the containment spray valve test switches be placed in the test position. Contrary to the above, Step 7.10 of Procedure OP ST-SI-3008, was not properly implemented in that on August 21,1997, in addition to placing the containment spray valves and the containment spray valve test switches in the required position, the control switches for Containment Spray Valves HCV-344 and HCV-345 were placed in the override position. This would have prevented the automatic actuation of either containment spray header if required. f 't 1 THIS APPARENT VIOLA TION IS SUBJECT TO FURTHER REVIEW AND MA Y BE REVISED 1

APPARENT VIOLATION 2. Technical Specification 2.4, " Containment Cooling " limiting condition for operation requires, in part, that Containment Spray Pumps SI-3A, SI 38, and SI 3C and their associated valves, piping and interlocks be operable during power operation. The modification of minimum requirements for the specification allows for two of these pumps to be inoperable at any one time during power operation. Technical Specification 2.0.1 requires in part that, in the event that the limiting condition for operation cannot be satisfied because of circumstances in excess of those addressed in the specificatio,1, the unit shall be placed in at least hot shutdown within 6 hours, and in at least subcritical and < 300*F within the next 6 hours. Contrary to the above, the unit was not placed in at least hot shutdown within 6 hours and was not in at least subcritical and <300 F within the next 6 hours on August 21,1997, when the containment spray system was rendered inoperable from approximately 8 a.m. CDT to 8:38 p.m. because of the control switches for both containment spray header isolation valves being placed in the override position. THIS APPARENT VIOLA TION IS SUBJECT TO FURTHER REVIEW AND MA Y BE REVISED

APPARENT VIOLATION 3. Technical Specification 5.8.1, requires that written procedures and administrative policies be established, implemented and maintained that meet or exceed the minimum requirements of Sections 5.1 and 5.3 of ANSI N18.7-1972 and Appendix A of Regulatory Guide 1.33, Regulatory Guide 1,33, Appendix A, Section 1.h requires procedures for shift and relief turnover, Procedure SO 0-1, " Conduct of Operations," Revision 33, provides procedural requirements for the conduct of shift and relief turnover, These requirements include: (1) the oncoming shift shall familiarize themselves with the conditions in areas for which they are responsible; (2) each person will brief his/her relief on the condition and status of that portion of the plant to which he/she is assigned, including abnormal conditions or alignments and inoperable equipment; and (3) prior to assuming the shift, each operator shall personally verify the status of important syster,, operating parameters, especially those relating to safety systems, Contrary to the above, on August 21,1997, the licensee failed to conduct an adequate shif t turnover in that the oncoming shif t did not identify that the control switches for both containment spray valves were in override, rendering the containment spray system inoperable, and that the off-going crew did not brief the oncoming crew about this condition, .THIS APPARENT VIOLA TION IS SUBJECT TO FURTHER REVIEW AND MA Y BE REVISED

APPARENT VIOLATION \\ 4. Technical Specification 5.8.1, requires that written procedures and administrative policies be established, implemented and maintained that meet or exceed the minimum requirements of Sections 5.1 and 5.3 of ANSI N18,71972 and Appendix A of Regulatory Guide 1.33. Regulatory Guide 1.33, Appendix A, Sect on i 1.h requires procedures for log entries. Star. ding Order 50 01, " Conduct of Operations," Revision 33, required that log entries into the official control room log be made when major plant equipment / systems were place in or out of operation, and to document compliance with the requirements of a Technical Specification Limiting Condition for Operation. Contrary to the above, on August 21,1997, operators f aile1 to log that the containment spray header isolation valves had been rendered inoperable by placing the control switches in override. Operators f ailed to properly log the operability of High Pressure Saft y injection Pemps SI 2A and SI 2C in that they were declared operabie prior to rendering the pumps operable by opening their respective discharge valves, in addition, as of 7 p.m. on August 28, operators had f ailed to log that Containment Spray Pump SI 3C was operable per Technical Specification. 2.4(1)b. The pump had been restored to an operable status on August 21. s THIS APPARENT VIOLA TION IS SUBJECT TO FURTHER REVIEW AND MA Y BE REVISED

Open or check open the pump suction Isolation Valve HCV-2967. / CAUTION Closing the pump discharge valve or o)ening the minimum recirculation valve renders t1e pump INOPERABLE. The applicable LCO action statements of Technical Specifications 2.1.1, 2.4, and 2.7 must be i Il implemented. Starting SI-3B with the pump discharge L valve closed renders the interlock for HCV 344 inoperable. Tech Spec 2.4(2)d (24 hour LCO) must be implemented for the interlock for HCV 344. / LSO 3. The Licensed Senior Operator has reviewed Technical Specifications 2.1.1, 2.4, and 2.7 and, if applicable, has logged the appropriate LCO into the Control Room Log. 4. Unlock and open SI-146, minimum recirc valve. / 3. Station a dedicated operator at the control switch for 51-38. The operator's function is to place the control switch for SI-38 in PULL-TO LOCK if any Engineered Safeguards actuation occurs. This prevents HCV-344 from opening and protects the remaining CS pumps.
