Equipment examined included the TDAFW pump, system piping and valves, and main control room controls and instrumentation, and the accessability of equipment required to be manually operated during an SBO. In addition, a walkdown was also performed to examine the 6900 VAC emergency buses 1A-SA and 1B-SB, the 480 VAC emergency buses 1A3-SA and 1B3-SB, the 125 volt direct current (VDC) Class 1E system, and non-nuclear safety related 125 and 250 VDC systems. The walkdowns were performed to assess material condition, identify degraded equipment and verify installed configuration were consistent with design drawings and calculation design inputs.
Operation The team reviewed the performance history and surveillance records for the TDAFW pump and system flow and vibration trending data to evaluate the performance of the TDAFW pump and to identify any trends indicating degrading equipment. The team also reviewed parameter trending and corrective maintenance history for the EDGs.
Parameter trending included lube oil pressure, temperature, cooler performance, and strainer delta P; fuel oil pressure; left and right bank exhaust temperatures; jacket water temperature, pressure, and heat exchanger performance; stator temperatures; governor rack position; fast start times; and crankcase pressure. Additionally, the team reviewed the vendor manuals and the preventive maintenance procedures for the EDGs, TDAFW pump, turbine, and trip and throttle valve to verify maintenance practices were consistent with the manufacturers recommendations.
Design EDG Support Systems The team performed a design review of the EDG support systems such as the fuel oil system and the ESW system to determine if the design bases assumptions of system capability were verified. This included flow verification for EDG ESW supply lines and equipment required to respond to an SBO. The review included design documentation, drawings, calculations, vendor manuals, test documentation, surveillance and maintenance procedures for installed equipment. Additionally, the implementation of the Harris SBO coping strategy for a four-hour coping period was reviewed.
Essential Alternating Current Power System The team reviewed selected portions of calculation E-6000 to verify that the degraded voltage relay dropout setting ensured that steady state voltage criteria were not violated on downstream emergency power system buses during switchyard degraded voltage conditions. The team reviewed the calculation to determine the maximum expected diesel generator loading during each sequencer load block, including the diesel generator terminal voltage response, during sequencing. The team also reviewed selected portions of calculation E-6003 to determine the adequacy of the class 1E bus voltages. In addition, the team reviewed coordination studies for 6900 VAC emergency bus 1A-SA, 480 VAC power centers 1A2-SA and 1A3-SA and selected 480 VAC motor control center power supplies. The review was performed to determine that selective circuit breaker coordination had been established for the Class 1E electrical distribution system.
Station Blackout DC (SBO- 10 CFR 50.63)
The team evaluated the battery sizing calculations to ensure proper considerations were taken in sizing the battery and to verify that the 125 VDC Class 1E and the Non-Class 1E Batteries have adequate capacity to support the decay heat removal for the required four-hour coping duration. The team reviewed vendor data, maintenance procedures and maintenance history for each battery system to determine whether adequate monitoring had been established. The team also reviewed plant procedure, EOP-EPP -
Loss of AC Power to 1A-SA and 1B-SB, to verify that the procedure instructions were consistent with the SBO calculations in identifying the direct current (DC) loads that are required to be shed during an SBO event.
Testing EDG and EDG Support Systems The team reviewed surveillance testing and inspection documentation for the EDGs to verify performance monitoring was adequate to assure that design capability was maintained and equipment degradation would be identified. The team also reviewed the surveillance test procedures which control testing of the TDAFW pump to verify testing requirements specified in the procedures were adequate. Additionally, completed test and inspection results were reviewed to assess the licensees actions to verify and maintain the safety function, reliability, and availability of the TDAFW pump. Response time testing of critical valves was included in the review. Test and inspection results were reviewed to verify that the results were consistent with design specifications, that test acceptance criteria and test results appropriately considered differences between testing conditions and design requirements during accident conditions, and that test and inspection results met established acceptance criteria.
DC Battery Systems The inspectors reviewed results of tests performed on the station batteries to verify all surveillance requirements as established by TS 4.8.2.1.d were properly being met. The team also reviewed test results performed to determine if LOOP mitigation loads could be adequately supplied by the batteries and without overloading the batteries during load sequencing. Time-current coordination studies were reviewed to verify that adequate selective coordination had been established for selected 125 VDC and 118 VAC loads (e.g. 125 VDC emergency bus panels, 118 VAC instrument panels). The EDG field flashing circuit (circuit No. 13) was also evaluated to ensure it could perform its function of fast-starting the EDG during an emergency. The inspectors reviewed EDG fast-start testing procedures, maintenance history, and circuit wiring diagrams to assess the performance of the field flashing circuit.
