REACTOR SAFETY Cornerstones: Initiating Events and Mitigating Systems 1R21 Safety System Design and Performance Capability (71111.21)
.1 System Needs a.
Inspection Scope Process Medium The team reviewed the availability, reliability, and adequacy of the condensate storage tank (CST) and the service water (SW) system supply for the auxiliary feedwater (AFW)
system to determine their capability to perform their design functions. This review included the protection of the CST against freezing weather and tornado missiles, the water volume of the CST, and the suction head pressure provided to the AFW pumps by the CST. The review also included the licensees actions to identify and prevent degradation of the SW supply piping to the AFW system due to clams, debris, and biofouling. To accomplish this review, the team inspected design documentation, drawings, calculations, test documentation, surveillance and operating procedures, and installed equipment.
The team also reviewed plant Technical Specifications (TS), the Updated Final Safety Analysis Report (UFSAR), and system descriptions to determine the requirements for the CST and the SW systems. This review also included a system walkdown, discussions with the system engineer, and review of operating and emergency procedures to verify that the installed system and procedures were consistent with these requirements.
Energy Source The team reviewed the reliability and availability of the steam supply to the turbine driven (TD) AFW pump. This was done to determine that the design and performance requirements of the steam supply valves and piping as specified in design documents were met. The licensees program to prevent condensate accumulation in the steam supply lines that could cause the pump to overspeed when started was also reviewed.
To accomplish this review, the team inspected design documentation, drawings, calculations, vendor manuals, test documentation, surveillance and operating procedures, and installed equipment.
Electrical Signals
The team reviewed electrical elementary and schematic drawings depicting the start logic for the motor driven (MD) and TD AFW pumps to verify that the logic design was consistent with the UFSAR and the AFW Functional System Description (FSD). The MD AFW pumps starting logic design was specifically reviewed to verify that the pumps
would automatically start on either 1) a loss of both feedwater pumps, 2) 2 out of 3 low-low level in any steam generator, 3) loss of offsite power, or 4) a safety injection signal.
Also, the team reviewed the start logic for the MD AFW pump room coolers to verify that the cooler motors were interlocked to automatically start on an AFW pump motor start when the control switch was in the Auto position. Similar to the above, the team reviewed the TD AFW pump start logic to verify that the pump would automatically start on either 1) 2 out of 3 reactor coolant pump bus undervoltage (blackout) signal or 2) 2 out of 3 low-low level signals on 2 out of 3 steam generators.
The team also reviewed the control logic for the AFW feed regulating valves and AFW SW supply valves to verify that the controls were consistent with design documents.
In addition to the above, the team reviewed the latest surveillance and functional test records for the AFW system to verify that all start circuitry was functionally tested periodically in accordance with test procedures, design drawings, and TS. The calibration test records for selected AFW process instruments were reviewed to verify that they were being calibrated and tested in accordance with the calibration program.
Electrical Power Sources The team reviewed electrical one-line drawings for the 4160 volt alternating current (VAC) switchgear, 600 VAC load centers and motor control centers (MCCs), the 120 VAC vital power system, and the 125 volt direct current (VDC) system to identify and ensure adequate power sources were available for the AFW system loads. The team reviewed the licensees evaluation of minimum expected voltage conditions to verify adequate protection was provided for the cables from overloads and short circuit conditions. In addition, the team reviewed fuse and breaker coordination studies on selected loads to verify protection between breakers and fuses was in accordance with equipment specifications.
The team evaluated the AFW uninterruptible power supply (UPS) and 48 VDC batteries to verify proper loading consideration was given to selected AFW components. The team reviewed periodic testing performed to demonstrate onsite AC emergency power supplies were capable of providing adequate voltage and current for the AFW loads in accordance with design requirements.
Instrumentation and Controls The team reviewed electrical elementary and schematic drawings depicting permissives and interlocks for valves and motor logic to verify that control logic was consistent with system functional requirements.
The team reviewed process drawings for the AFW system to ensure adequate alarms and indications were available to operators to make decisions regarding operation of the system. The team also reviewed completed surveillance test procedures to verify that valve position indications associated with selected AFW valves were being functionally tested on a periodic basis. In addition, the team reviewed calibration test records to verify that the instruments were included in a periodic calibration test program.
Operator Actions The team reviewed pertinent operator instructions, including emergency operating procedures, performed a system walkdown with a licensed operator to determine access to components listed in operating procedures, reviewed an ongoing surveillance test of the TD AFW pump to determine procedural control, adequacy of testing, and communications. The inspectors also reviewed the list of operator work arounds to determine if there were any AFW related issues.
Heat Removal
The team reviewed availability and reliability of the subsystems required to remove heat from the AFW pumps and pump rooms during normal and accident conditions as specified in design basis documents. To accomplish this review, the team reviewed drawings, test documentation, surveillance procedures, operating procedures, and installed equipment.
b.
Findings No findings of significance were identified.
.2 System Condition And Capability a.
Inspection Scope
Installed Configuration The team performed field walkdowns of the AFW system to assess material condition, identify degraded conditions, and verify that the installed configuration was consistent with the design drawings and design inputs to calculations. Additionally, the team inspected the flood detection devices, watertight doors, drains, and sump pumps to verify the capability to detect and limit the effects of internal flooding in or near the AFW pump rooms.
The team performed selective field inspections of the AFW pump rooms and pumps; isolation, flow control, and turbine steam supply valves; and the CST. Particular attention was focused on the installation and configuration of piping, components, and instruments; the placement of protective barriers and systems; the susceptibility to flooding, fire, tornados, cold weather, or other environmental concerns; physical separation; provisions for high energy line breaks; accessibility for operator action; and the conformance of the installed configurations with the design and licensing bases.
The team performed a walkdown inspection of 600 VAC MCCs (i.e. MCC 1U and 2V) to verify that the installed configuration was consistent with design drawings. The team performed visual inspections inside of selected MCC compartments to verify that the types and sizes of installed fuses, overloads, reversing starters, and molded case breakers, were consistent with design documents. The material condition of the internal electrical wiring was also visually inspected for any signs of apparent physical degradation from conditions such as overheating. The team also observed, during walk-
downs, the material condition of other AFW related equipment such as motor operated valves, (MOVs), temperature recorders, TD AFW and MD AFW pumps, AFW hot shutdown panels, AFW process instrumentation, and AFW UPS and 48 VDC battery banks.
Design Design and test documents were reviewed to determine if the design basis assumptions of system capability were verified. This included pump discharge pressures, net positive suction head (NPSH), and valve stroke times. To accomplish this review, the team inspected design documentation, drawings, calculations, vendor manuals, test documentation, and surveillance and maintenance procedures.
The team reviewed the design calculations that sized the feeder cables for the AFW pump motors to verify that the cables were sized to provide adequate voltage and current to the motors. The team reviewed calculations that determined voltage drop on the 4160 VAC buses when starting an AFW pump from the diesel generator. The team reviewed the environmental qualification for selected AFW system components to verify compliance with 10 CFR 50.49.
The team reviewed design calculations, vendor manuals, and motor data sheets to verify that the ground and phase overcurrent relays for the AFW pump motors were set at appropriate thresholds to allow adequate protection without causing spurious trips.
The team reviewed design calculations that determined the required opening and closing stem thrust for MOVs to verify that during a design basis event, the AFW MOVs would be able to perform their desired function.
Testing The team reviewed the programs and procedures using TS and design basis requirements for inservice testing and inspection of the safety-related valves and pumps in the AFW system. The team also reviewed the testing of pump vibration and lubricating oil. These reviews included testing results for selected pumps and valves, pump manufacturer pump curves, pump and valve inservice test trend records, and oil and vibration testing. On March 19, the team observed actual surveillance testing of the Unit 2 TD AFW pump.
The team reviewed calibration test records and functional test procedures to verify that critical AFW system level, flow, and pressure instrumentation were being monitored and calibrated in accordance with calibration procedures. The team reviewed the as-found and as-left instrument calibration records to verify that the instrument settings met procedural requirements. The team assessed whether identified test deficiencies or out of tolerance conditions were properly evaluated and corrected by reviewing the last two completed calibrations performed to determine if instruments were continuously drifting outside the allowable response band between calibrations. The team also reviewed functional test procedures to verify that the AFW pump start/stop switch, local/remote switch, flow control valve reset, and AFW valve position indication were functionally tested.
The team reviewed the latest calibration records for the AFW pump motors and bus supply breaker protective relays to verify that relay setpoints (i.e., as-found and as-left) were in accordance with approved plant procedures and TS.
Operation The team reviewed periodic testing procedures and results to determine if the system performance satisfied design analysis and TS requirements. The team also reviewed the AFW systems operation by conducting system walkdowns; reviews of normal, abnormal, and emergency operating procedures; review of the UFSAR, TS, design calculations, drawings, system engineer notebooks and procedures; and discussions with operators and system engineers. Inspection emphasis was placed on modifications of the design and changes to the normal and emergency operating procedures to ensure system availability, reliability, and functional capability had been maintained. The team also reviewed the TS required surveillance to determine that each requirement was in the test program.
The team performed a system walkdown of the AFW system to assess system material condition, verify configuration, and identify potentially degraded conditions. During this walkdown, the team reviewed the cold weather preparations in effect, required Appendix R lighting in some of the AFW pump rooms, administrative controls of combustion material, and temporary system alterations. The team also performed a control board walkdown and discussed system performance history with several licensed operators.
b.
Findings No findings of significance were identified.
.3 Selected Components a.
Inspection Scope Component Inspection The team reviewed maintenance and testing documentation to assess the licensees actions to verify and maintain the safety function, reliability, and availability of selected components. Specifically, the team reviewed at least 2 years of both preventive and corrective maintenance history, for a selection of 4160 VAC and 600 VAC breakers, AFW pump motors, AFW pump room sump pump motors, and AFW motor operated valves. Additionally, potential common cause failure mechanisms due to flooding, maintenance, and parts replacement were reviewed. The selected equipment included pumps, tanks, and a risk-based selection of critical valves.
The team reviewed completed work orders for the replacement of environmentally qualified limit switches that had reached the end of life qualification.
Design Changes The team reviewed design changes of equipment performed through the licensees design change process and component level design changes accomplished through the procurement process to verify that system and equipment function were appropriately evaluated and maintained.
