Licensee Action on Previous Inspection Findings None Unresolved Items Unresolved items were not identified during this inspectio.
Followup on Previously Identified Items (Closed) Item 261/79-11-06 Review of Controls on an electrical Distribu tion Manual - During the inspection reported in IE Report 50-261/79-11, the inspector observed an electrical distribution manual in the control room which did not appear to be administratively controlled to assure appropriate updating and revie The item was identified as open pending a review to determine use of the manual for safety-related activitie On January 22, 1980, the licensee reissued the manual, into the control led document system, as Appendix A to "Systems Description N ".
This action places the manual in a system which is administratively controlled for updating and review of proposed revision (Closed) Item 261/79-12-07 Revised Operator Training Procedure - The inspector reviewed Administrative Instruction N, Paragraph 1 entitled "Operator Requalification Program" which requires that shift personnel be trained on shift in alarm settings, safety limits, abnormal condition symptoms, limiting condition for operations, operating sequences, and emergency immediate action step Individual reviews, instructional sessions walk through of controls and instrumentation will be conducted such that information in the above areas is covered quarterly except during the refueling quarte The administrative instruction further requires that a report be prepared quarterly detailing the information covered for each member of the shift opera tion crew and will contain the shift foreman's judgment of each operator's familiarity with the information indicated as well as each operator's ability to the actions required in abnormal and emergency situation (Closed) 261/79-17-01 Performing Procedural Steps out of Sequence -
On inspection 261/79-17 conducted August 1979, the inspector had observed that in performing general procedures some steps in the procedures were not performed in chronological orde A licensee representative stated they had reviewed the open item and had concluded that insertion of the following paragraph into each General Procedure would authorize the performance of procedural steps out-of sequence if appropriat All steps shall either be initialed when performed or if the step is met by existing plant conditions, it may be marked (not applicable) and initialed by the shift forema If the safe efficient operation of the plant so dictates, the steps may be performed simultaneously or out of sequenc The inspector concurred with their approac.
Plant Operations Facility Tours The inspector conducted several facility tours during normal and backshifts. Inspection activities in this area included observation to insure that; instrumentation was operating and calibrated as required, radiation controls were established and properly adhered to, fire protection equipment was located as specified and appeared operabl In addition, selected valves, breakers and control switches were verified to be properly aligned as required by Technical Specifications and plant procedure No items of noncompliance were identifie Control Room Operations Control room operation was observed and discussed with control room personnel to assure compliance with Technical Specifications and plant
-3 administrative requirement Inspection activities included observation of selected instrumentation to assure plant operation within required limits, observation of surveillance testing and shift turnover, verifi cation of control room manning in conformance with the requirements of 10 CFR 50.54(k),
and discussions with control room operators pertaining to selected parameters and annunciator No items of noncompliance in this aer.
Reactor Protection System Logic Train Testing While performing a monthly periodic test of Reactor Protection Logic Trains, sequential failure of two NBFD-31S relays occurred in the "A" logic trai The failed relays are Westinghouse 125/130 volt DC and are the same type as the three relays which failed in the "B" logic train on March 24, 198 The relays are normally operated energized and the failures which have occurred would not have prevented required safety circuit action The problem appears to be generi There are ten of the NBFD Relays in each logic train. They were installed in May 1979. Westinghouse has been supplied six used relays removed from service in the Robinson reactor protection system logic train plus six unused relays of the same type removed from the licensee's store The licensee stated accelerated testing would begin on the relays in the near futur The most recent type of failure experienced on the relays is
"failsafe" in that failure would not prevent required safety circuit action This item will remain open pending completion of Westinghouse tests (261/
80-18-01).
