The inspection found that maintenance, testing, and operation of the low head and high head safety injection systems were consistent with the design and licensing basis.
During this inspection the licensee initiated several Condition Reports which are listed in the Appendix. No violations were identified.
REPORT DETAILS
REACTOR SAFETY
CORNER STONES MITIGATINGSYSTEMS R21 SAFETY SYSTEM DESIGN INTRODUCTION The objective of this Safety System Design and Performance Capability Inspection was to assess the adequacy of calculations, analyses, other engineering documents, and maintenance practices that were used to support the performance of the low head safety injection (LHSI)function of the residual heat removal (RHR) system and the high head safety injection (HHSI)system during normal and accident or abnormal conditions.
The inspection was performed by a team of inspectors that included a Team Leader, four Region II Specialist Inspectors, and a Resident Inspector.
The systems, structures, and components (SSCs) examined during the inspection were selected by reviewing the licensee's probabilistic risk model to determine the dominant SSCs ranked by importance in their potential contribution to dominant accident sequences and/or initiators.
Acceptance criteria utilized by the NRC inspection team included the Shearon Harris Technical Specifications (TS), applicable sections of the updated Final Safety Analysis Report (UFSAR), Section=11 of the American Society of Mechanical Engineers (ASME) Code, industry initiatives implemented by the licensee, licensee procedures, and the design bases for the systems.
Prior to this inspection, the licensee performed a self-assessment which included review of the design and licensing basis of the LHSI and HHSI systems.
SYSTEM REQUIREMENTS WATER SOURCE The team conducted a walk down inspection of the "A"train RHR and "B"train safety injection (Sl) systems to verify that a sufficient quantity of borated water willbe available and unimpeded during accident/event conditions for the HHSI and LHSI systems.
The team reviewed the calculations for sizing the refueling water storage tank (RWST) and establishing various level requirements in the RWST to verify that sufficient quantities of water are available for accident and normal operating conditions, and calculation SC-N-157 which established RWST level instrumentation setpoints.
The team also reviewed the results of monthly surveillance tests performed in accordance with OST -1107 which verifies that the ECCS piping is full of water, thereby reducing potential for occurrences of a water hammer during system initiation, and tests performed in accordance with MST-1004 which demonstrate that RWST level transmitters calibrations are accurate.
Observations and Findin s There were no findings identified and documented during this inspection.
ELECTRICALPOWER SOURCE POWER SUPPLY TO PUMP MOTORS Ins ection Sco e
The team reviewed the pump performance curve forRHR pump 18-SB to verify that the LHSI pump motors had been adequately sized based on process system parameters.
The team performed alternate calculations in order to verify that the HHSI pump motors had been adequately sized and the plant electrical distribution system would be adequate for motor operation during a design basis loss of coolant accident (LOCA).
Using applicable design input information from Calculation E-6000, AuxiliarySystem Load Study, the team performed alternate calculations to evaluate the capability of the plant electrical distribution system to support operation under the most degraded voltage condition and to verify that the plant electrical distribution system would be adequate for LHSI and HHSI motor operation during a LOCA.
Observations and Findin s There were no findings identified and documented during this inspection.
CONTROL SYSTEM CHARGING / SAFETY INJECTION SYSTEM OPERATION
'
Ins ection Sco e
The team reviewed design output documents and calculations to verify that the control system
'logic generated by the volume control tank (VCT) level switches and the engineered safeguard "S" signal enabled the charging/safety injection pumps (CSIPs) to take suction from the VCT during normal conditions and from the RWST during accident conditions. The team reviewed the logic for the VCT level transmitters 1-LT 112 and 1-LT115 which provide the control signals which automatically realign the suction of the from the VCTto the RWST by closing motor operated valves (MOVs) 1CS-165 and 1CS-166.
Observations and Findin s There were no findings identified and documented during this inspection.
COLD LEG RECIRCULATION PHASE Ins ection Sco e
The team reviewed design output documents and calculations to verify that the control circuit protection logic which provide control signals to open containment sump isolation valves 1SI-
300, 1SI-301, 1SI-310, and 1SI-311 and align the two RHR pumps to take suction from the containment sump during the recirculation phase following a design base accident were adequate.
Observations and Findin s There were no findings identified and documented during this inspection.
TRANSITION FROM INJECTION TO RECIRCULATION PHASE Ins ection Sco e
The team reviewed design output documents and calculations to verify that the control systems provide desired control during transition from the injection phase to the recirculation phase during accident conditions. The team reviewed the electrical interlock of the RHR to CSIP isolation valves 1RH-25 and 1RH-63 to verify that controls permitted the operators to manually isolate the RWST from the RHR pumps and align them to deliver flowto the CSIP suction header as specified in system description SD-111.
Observations and Findin s There were no findings identified and documented during this inspection.
OPERATOR ACTIONS The team reviewed operating procedures for transferring emergency core cooling systems (ECCS) from injection phase to cold leg recirculation phase, and between cold leg and hot leg recirculation, to verify that the procedures specify correct operator actions, and can be performed in the time required as described in the UFSAR. The team performed a walkdown of the reactor turbine gauge board (RTGB) in the control room to verify that instrumentation and alarms for RWST level, VCT level, Sl and RHR flows and pressures were available and adequate for the operators to make the necessary decisions during performance of the emergency operating procedures (EOPs), and that placement of controls and indications allowed operators to perform the required actions in the times specified in the USFAR.
Observations and Findin s There were no findings identified and documented during this inspection.
ENVIRONMENTALQUALIFICATION Ins ection Sco e
