10 CFR 50.73.b requires, in part, that Lic … 10 CFR 50.73.b requires, in part, that Licensee Event Reports (LER) shall contain a brief abstract describing the major occurrences during the event, including all component or system failures that contributed to the event and significant corrective action taken to prevent recurrence. In addition, the LER shall contain a narrative description of the cause of each component or system failure, the effect of each failed component, and operator actions that affected the course of the event, including procedural deficiencies that contributed to the event</br>Contrary to the above, on February 16, 2001, Licensee Event Report (LER) 50-321/00- 02: Reduction in Reactor Feedwater Flow Results in Automatic Reactor Shutdown on Low Water Level, dated February 25, 2000, did not contain all information as required by 10 CFR 50.73.b. Specifically, the LER did not contain the significant complications encountered with the Reactor Core Isolation Cooling (RCIC) system failure, the cause of the RCIC system failure, or the effect of the RCIC system failure on the event. The LER did not identify several unsuccessful attempts to restart the RCIC system after the RCIC turbine tripped on high reactor water level following a reactor trip. The LER also did not document certain operator actions that affected the course of the event involving the RCIC system, including an operating procedure that allowed the operator to restart the RCIC system turbine by opening the Trip and Throttle valve with the steam supply valve full open and the turbine control system demanding maximum speed. This method of restarting the tripped RCIC system contributed to repetitive overspeed trips of the RCIC turbine during the event. In addition, the LER did not contain a description of the significant corrective actions taken or planned to prevent recurrence of the RCIC system failure.ent recurrence of the RCIC system failure. +
