The inspectors identified an apparent violation of
Technical Specification 5.4.1.a, which requires that written procedures be established, implemented, and maintained covering the applicable procedures recommended in
Regulatory Guide 1.33, Revision 2, Appendix A, February 1978.
Regulatory Guide 1.33, Revision 2, Appendix A, Item 4.n requires instructions for operation of the condensate system. System Operating Procedure SOP-0007, Condensate System, Revision 21, required Condensate Prefilter Vessel Bypass Flow Control Valve CNM-FCV200 to be locked open. On September 18, 2002, Valve CNM-FCV200 was found to be not properly locked open. The failure to properly lock Valve CNM-FCV200 in the open position resulted in unexpected closure of the valve and a loss of
feedwater flow to the reactor vessel following a reactor
scram. The final significance of this issue will be determined using the
Significance Determination Process (Section 3.5).
