COMMON SENSORS FAITURES 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 CONCLUSIONS 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 BSR Inc 8 GE Determine Failure Mode BSR Inc S GE Summarize Common Sensor Failures

~ Analyze Combined Effects GE Compare Results to Chapter 15

~ Analyze Exceptions

~ Modify/Augment Chapter 15 if Necessary

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 SPL ~Settee NB Nuclear Boiler MS Main Turbine Generator RRC Reactor Recirculation CW Circulating Water CRD CRD Hydraulic SW Service Water RFT Feedwater Turbine CAS Control and Service Air NMS Neutron Monitoring AR Air Removal PRM Process Radiation Monitoring COND Condensate ARM Area Rad Monitoring DEH Main Turbine Control RWCU Reactor Water Cleanup TO Main Turbine and Feedwater MS Main Steam Turbines Lube Oil ES Exhaust Steam Seal Steam BS Bleed Steam-Extraction Steam Main Generator Cooling HV Heater Vents Main Generator Hydrogen and HD Heater Drains C02 Purge MD'iscellaneous Drains RCC RB Cooling Water MV Miscellaneous Vents 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.

SUMMARY

RESULTS AND CHAPTER 15 COMPARISONS Instrument Line Line Failure Conse uences No. 1 Line break initiates a decrease in feedwater flow and trip of Recirc Pump A. Reactor scram is 'a direct consequence. Reactor scram will not cause adverse consequences. Plugged line has no effect.

No. 2 Line break initiates increased feedwater flow, resulting in reactor scram. Reactor scram will not cause adverse consequences. Plugged line has no effect.

No. 3 No effect No. 4" No effect No. 5 No effect 12-0288 4

Instrument Line Zine Failure Cense uences No. 6 Breaking of this instrument line initiates a Main Turbine Trip. A Main Turbine Trip event is analyzed in Chapter 15. Plugged line has no effect.

No. 7 No effect No. 8 No effect No. 9 No effect No. 10 No effect No. 11 No effect No. 12 No effect No. 13 Line break initiates a decrease in feedwater flow resulting in reactor scram. Reactor scram will not cause adverse consequences. Plugged line has no effect.

No. 14 Line break prevents automatic SRV initiation; this event is analyzed in Chapter 5. Plugged line has no effect.

No. 15 Line break initiates closure of all main steam line valves causing a reactor scram. Reactor scram takes precedence over other sensor failure consequences.

Reactor scram will not cause adverse consequences..
