COMMON SENSORS FAII,URES EVALUATION REPORT APRIL 1983 PREPARED FOR WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO.2 PREPARED BY P.R.SC1iEKR GENERAL ELECTRIC COMPANY, NUCLEAR ENERGY BUSINESS OPERATIONS SAN JOSE, CALIFORNIA 95125 APPROVED: T.R.Wortham, Manager Technical Iicensing Nuclear Control and Instrumentation DePartment P.B..Kingston, Licensing Engineer Safety and Licensing Operation 12-0288 PDR 5~8~phip AD0cg PgPPO~9y PDR I

COMMON SENSORS FAIT URES EVALUATION REPORT FOR WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT NO.2 l.0 OBJECT This document constitutes:

An analysis in response to the NRC concern that the failure of an instrument line which contains sensors to multiple control systems could result in consequences outside the bounds'f the Washington Public Power Supply System Nuclear Project No.2 (WNP-2)Final Safety Analysis Report (FSAR)Chapter 15 analysis and beyond the capabil>>ities of operators or safety systems.~A positive demonstration that adequate'common'sensor review and analysis has been performed to ensure that despite such failure the WNP-2 FSAR Chapter 15 analyses are bounding, and no consequences beyond the capability of operators or safety systems would result.A comprehensive approach was developed to analyze the control systems capable of affecting reactor water level, pressure, or power in the Nuclear Plant No.2 Evaluation Report for Control Systems Failures.This Cosmon Sensor Report uses the knowledge of which systems affect reactor water level, pressure or power, gained in Evaluation Report for Control Systems Failures, for valid restriction of this analysis to only those systems.This report was prepared by General Electric Company for Washington Public Power Supply System Nuclear Pro]ect No.2 with a significant technical contribution from Burns 6 Roe, Incorporated (BSR Inc.), the Principal Architect Engineer.

2.0 CONCLUSION

S This report, supplemented by existing FSAR Chapter 15 transient analysis, documents an evaluation of WNP-2 Nuclear Power Station for common sensor failures.No new transient category events have been postulated as a result of this study.All the uncovered consequences (Reactor Scram, Turbine trip, Feedwater increased/decreased flow)are bounded by FSAR Chapter 15 analysis.3.0 ANALYSIS METHODOLOGY The common sensor failure analysis was conducted in the following manner by GE and BSR Inc: 12-0288 2

Activit~Identify Common Sensors Determine Failure Mode Summarize Common Sensor Failures~Analyze Combined Effects Compare Results to Chapter 15~Analyze Exceptions

~Modify/Augment Chapter 15 if Necessary BSR Inc 8 GE BSR Inc S GE GE 3.1 IDENTIFY COMMON SENSORS The systems that effect reactor water level, pressure or power were analyzed for instrument lines with sensors for more than one system.The Evaluation Report for Control Systems Failure identified those systems that effect reactor water level, pressure or power as follows: SPL~Sstess NB Nuclear Boiler RRC Reactor Recirculation CRD CRD Hydraulic RFT Feedwater Turbine NMS Neutron Monitoring PRM Process Radiation Monitoring ARM Area Rad Monitoring RWCU Reactor Water Cleanup MS Main Steam ES Exhaust Steam BS Bleed Steam-Extraction Steam HV Heater Vents HD Heater Drains MD'iscellaneous Drains MV Miscellaneous Vents SPL~Settee MS Main Turbine Generator CW Circulating Water SW Service Water CAS Control and Service Air AR Air Removal COND Condensate DEH Main Turbine Control TO Main Turbine and Feedwater Turbines Lube Oil Seal Steam Main Generator Cooling Main Generator Hydrogen and C02 Purge RCC RB Cooling Water TSW TB Cooling Water 3.2 DETERMINE FAILURE MODE The postulated probable failures are either that an instrument line is plugged (pinched)or broken.The worst case would be any total combination of common sensor failures that can, be postulated from a single failure.12-02SS 3

3.3 SUMMARIZE COMMON SENSOR FAIIURES The common sensor failure table (attachment to this report)lists all the instrument lines with sensors and their failure modes.The combined failures are the consequences that the NRC is concerned with.3.4 ANALYZE COMBINE EFFECTS This step used two approaches.

The first approach totaled all effects as worst case failure of the instrument line.There were no single effects that mitigated the total failure consequences.

The second approach considered piobable failures where the reactor scram had taken precedent over the other failure effects.In these instances the instrument line was analyzed as to whether a probable failure could be postulated without the reactor scramming.

No such failure could be postulated.

3.5 COMPARE RESULTS TO CHAPTER 15 The combined effects as identified in common sensor table were reviewed and evaluated.

Section 4 includes these evaluations, considering worst case effects.3.6 ANALYZE EXCEPTIONS There were no exceptions to FSAR Chapter 15 analysis.3.7 MODIFY/AUGMENT CHAPTER 15 IF NECESSARY This step was not necessary in the WNP-2 analysis.4.0 COMMON SENSOR
