Title | Relates to the air binding of the common low pressure core spray and residual heat removal (RHR) A water leg pump following August 14, 2003, loss of offsite power event. |
Description | During an NRC inspection conducted from October 1 through December 31, 2003, 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 5.4 requires, in part, that procedures shall be established, implemented and maintained as recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Appendix A, Section 4, Procedure for Startup, Operation, and Shutdown of Safety Related BWR Systems, recommends the establishment of written procedures for venting of emergency core cooling systems. Contrary to the above, as of August 14, 2003, the licensee had not established adequate written procedures to periodically vent the high point on the discharge of the common Low Pressure Core Spray (LPCS) and Residual Heat Removal (RHR) train A water leg pump. Specifically, the licensee did not include Valve N27F786 in Procedures SVI-E21-T1181, LPCS Venting and Valve Lineup Verification, Revision 4 or SVI-E12-T1182A, RHR A LPCI Valve Lineup Verification and System Venting, Revision 2. As a result, gas accumulated in the vertical section of piping on the discharge of the water leg pump and, following a loss of offsite power on August 14, 2003, the accumulated gas expanded, air bound the water leg pump and rendered LPCS and RHR A inoperable. This violation is associated with a White Significance Determination Process finding. Pursuant to the provisions of 10 CFR 2.201, FirstEnergy Nuclear Operating Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555 with a copy to the Regional Administrator, Region III, and a copy to the NRC Resident Inspector at the Perry Nuclear Power Plant, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a \\\\\\\\\\\\\\\"Reply to a Notice of Violation; EA-04-020\\\\\\\\\\\\\\\" and should include for each violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation or severity level, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved. Your response may reference or include previous docketed correspondence, if the correspondence adequately addresses the required response. If an adequate reply is not received within the time specified in this Notice, an order or a Demand for Information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time. |
