{{#Wiki_filter:- -. _. - . - - ~ - - ENCLOSURE 1 NOTICE OF VIOLATION TU Electric Docket Nos.: 50-445 Comanche Peak Steam Electric Station 50-446 License Nos.: NPF-87 NPF-89 During an NRC inspection conducted on September 29 through November 9,1996, 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 Specification 4.0.5 requires that inservice testing of ASME Code Class 1,2, and 3 pumps and valves be performed in accordance with Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda as required by 10 CFR 50.55a. Section XI, Subsection IWV, " Inservice Testing of Valves in Nuclear Power Plants," requires that valve testing be performed in accordance with the requirements stated in ASME/ ANSI OM, Part 10. Paragraph 4.3.1 of Part 10 states, in part, that safety and relief valves shall meet the inservice test requirements of Part 1. ASME/ ANSI OM, Part 1, Paragraph 7.3, " Periodic Testing," states, in part, that no maintenance, adjustment, disassembly, or other activity which could affect "as found" set pressure or seat tightness data is permitted prior to testing. Contrary to the above, a procedure change dated September 30,1996, to Procedure MSM-GO-0204, Revision 4, required that valves be cycled to remove entrapped air, an activity that could affect the "as found" set pressure. Four Unit 1 relief valves were cycled to remove entrapped air, prior to "as found" testing, usir.g licensee Procedure MSM-GO-0204 during the Unit 1 refueling outage as follows: (1) the containment sump to Containment Spray Pump 1-02/1-04 suction l isolation valve bonnet relief valve on October 9,1996 L (2) the containment ventilation chilled water return header outside containment relief valve on October 16,1996 l (3) the demineralized water / reactor makeup water outside containment building relief valve on October 17,1996 (4) the reactor makeup water to Pressurizer Relief Tank 1-01 outside l containment building relief valve on October 18,1996 l This is a Severity Level IV violation (Supplement l} (50-445/9612-03). l Pursuant to the provisions of 10 CFR 2.201, TU Electric is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: } Document Control Desk, Washington, D.C. 20555 with a copy to the Regional { Administrator, Region IV,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, and a 9612050069 961127 PDR ADOCK 05000445 ( PM ...gm v
