RRAS Watts Bar 2 NSSS Completion Post Accident Monitoring System Program I&C Projects System Requirements Specification SECTION 1 INTRODUCTION 1.1 PURPOSE This document defines the functional requirements for the Watts Bar Unit 2 Post Accident Monitoring System (PAMS) based on WCAP-16097-P-A, "Common Qualified Platform Topical Report Post Accident Monitoring System (PAMS), Appendix 1" (Reference 1). The Watts Bar Unit 2 PAMS allows setpoint changes and signal bypasses from both the operator's module (OM) and maintenance and test panel (MTP).

The Watts Bar Unit 2 PAMS requirements have been built upon the generic system requirements for the Common Qualified platform (Common Q) Phase 3 PAMS, 00000-ICE-30156, "System Requirements Specification for the Common Q Post Accident Monitoring System" (Reference 2). Those sections of Reference 2 that require modifications are defined in this document. The Watts Bar Unit 2 PAMS will include the Reactor Vessel Level Instrumentation System (RVLIS) as the vessel level monitoring system.

The requirements for the RVLIS are defined in this document.

1.2 SYSTEM SCOPE The system described in this document is intended to monitor accident conditions and inadequate core cooling (ICC) and provide information and data to the plant monitoring computers for use in its control room display.

The Watts Bar Unit 2 PAMS is comprised of two independent and isolated trains. The instruments used to provide the input signals to the Watts Bar Unit 2 PAMS are not included in the scope of this document.

The PAMS includes flat panel displays (FPDs) for the OM and MTP. The generic system requirements for the FPD are provided in 00000-ICE-30155, "System Requirements Specification for the Common Q Generic Flat Panel Display" (Reference 4).

The Watts Bar Unit 2 PAMS is based on the Westinghouse Common Q PAMS standard design. The Watts Bar Unit 2 PAMS includes the following subsystems:

Saturation Margin Monitor (SMM) 0 Core Exit Thermocouple Monitoring System (CETMS) 0 Reactor Vessel Level Monitoring System (RVLMS)

The PAMS design bases are as follows:

Provide safety grade processing and display for ICC instrument signals to detect the approach to, existence of, and recovery from ICC conditions per NUREG-0737, "Clarification of TMI Action Plan Requirements" (Reference 7),Section II.F.2, and Regulatory Guide 1.97, "Instrumentation for Light Water Cooled Nuclear Power Plants to Assess Plant Conditions During and Following an Accident" (Reference 5).

The Watts Bar Unit 2 PAMS will include the Reactor Vessel Level Instrumentation System (RVLIS) as the vessel level monitoring system.

The requirements for the RVLIS are defined in this document.

1.2 SYSTEM SCOPE The system described in this document is intended to monitor accident conditions and inadequate core cooling (ICC) and provide information and data to the plant monitoring computers for use in its control room display.

The Watts Bar Unit 2 PAMS is comprised of two independent and isolated trains. The instruments used to provide the input signals to the Watts Bar Unit 2 PAMS are not included in the scope of this document.

The PAMS includes flat panel displays (FPDs) for the OM and MTP. The generic system requirements for the FPD are provided in OOOOO-ICE-30155, "System Requirements Specification for the Common Q Generic Flat Panel Display" (Reference 4).

The Watts Bar Unit 2 PAMS is based on the Westinghouse Common Q PAMS standard design. The Watts Bar Unit 2 PAMS includes the following subsystems:

Saturation Margin Monitor (SMM)

Core Exit Thermocouple Monitoring System (CETMS)

Reactor Vessel Level Monitoring System (RVLMS)

The PAMS design bases are as follows:

Provide safety grade processing and display for ICC instrument signals to detect the approach to, existence of, and recovery from ICC conditions per NUREG-0737, "Clarification ofTMI Action Plan Requirements" (Reference 7), Section ILF.2, and Regulatory Guide 1.97, "Instrumentation for Light Water Cooled Nuclear Power Plants to Assess Plant Conditions During and Following an Accident" (Reference 5).

WNA-DS-01617-WBT-NP, Rev. 1 1-1

RRAS Watts Bar 2 NSSS Completion Post Accident Monitoring System Program I&C Projects System Requirements Specification Provide safety grade processing and display of accident monitoring instrument signals per Reference 5.

Provide a processing and display system that incorporates human factor engineering techniques to enhance the control room design by displaying essential plant parameters in a systematic and efficient manner per Reference 7,Section I.D. 1.

Provide safety grade isolation of Class 1E data to be provided to non-Class IE monitoring system(s).

1.3 SYSTEM OVERVIEW The PAMS is a Class 1E safety-related alarm and display system. The Watts Bar Unit 2 PAMS consists of two independent trains of equipment (Trains A and B) which acquire and process two trains of inputs.

The trains are physically separated and electrically isolated from each other. Each train of the Watts Bar Unit 2 PAMS shall be comprised of two Advant Controller 160 (AC160) racks located in one cabinet.

Figure 2.1-2 shows the typical configuration of the PAMS.

For each train, the Primary AC160 rack shall contain a processor that processes all incoming core exit thermocouple (CET), SMM, and reactor vessel level (RVL) signals. The processor receives inputs from its input cards. The processor performs input processing and algorithms, and sends the outputs to its output cards and over the AF 100 to the OM, and the MTP. The MTP has an Ethemet port that provides the capability to send data to the plant computer.

I The OM will be mounted in the main control room (MCR). The OM uses the Flat Panel Display System (FPDS), which consists of a PC node box, an FPD with touch screen capability, a standard AF 100 I communication interface for communication to the processor module and a power supply. The OM shall display various display pages.

The OM receives the signals to be displayed over the AF 100 from the PAMS processors.

The general relationship of the individual systems for Watts Bar Unit 2 PAMS are described below and provided in Figure 1.3-1.

The RVLMS monitors reactor vessel head differential pressure, lower range differential pressure, and dynamic range differential pressure to measure reactor coolant level in the vessel.

The CETMS monitors CET temperatures to detect and alarm ICC conditions.

The SMM uses the representative CET temperature, Reactor Coolant System (RCS) pressure, and the maximum RCS hot leg temperature to calculate saturation margins.

Each train of Watts Bar Unit 2 PAMS provides the combined functions of the ICCMS (i.e., SMM, CETMS, and RVLMS).

Only instrumentation of highest reliability and quality shall be used for the PAMS.

The PAMS variables may be categorized by the following critical functions:

RCS Inventory Control RCS Pressure Control Core Heat Removal RCS Heat Removal The bases used for selecting the parameters to be displayed for each critical function are "emergency procedure guidelines" and "the Regulatory Guide 1.97" (Reference 5).

The emergency procedure guidelines require certain instrumentation to be used for diagnosing events.

These key variables are monitored by the operator to determine what event is taking place, so that he may perform immediate actions and consult the emergency procedures. The guidelines also call for instrumentation to diagnose the accomplishment of plant safety functions. The operator uses these instruments to assess the safe status of the plant, independent of the event or events existing.

Regulatory Guide 1.97 (Reference 5) requires instrumentation to be used to assess plant conditions during and following an accident. Those instruments applicable to the PAMS are those used to determine plant safety status and to indicate the integrity of barriers to radioactive release.

The proprietary information as submitted by Westinghouse is that associated with the NRC review of the Post Accident Monitoring System (PAMS) being designed for Watts Bar Unit 2 and may be used only for that purpose.

5 CAW-10-2876 This information is part of that which will enable Westinghouse to:

(a)

Assist the customer in providing requested technical licensing information to the NRC that is required for approval of the Common Q Post Accident Monitoring system (PAMS).

Further this information has substantial commercial value as follows:

(a)

Westinghouse plans to sell the use of similar information to its customers for purpose of other plant-specific applications.

(b)

Its use by a competitor would improve his competitive position in the design and licensing of a similar product.

(c)

The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by Westinghouse.

Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar instrumentation & control systems and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.

The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.

In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.

Further this information has substantial commercial value as follows:

(a)

Westinghouse plans to sell the use of similar information to its customers for purpose of other plant-specific applications.

(b)

Its lise by a competitor would improve his competitive position in the design and licensing of a similar product.

Cc)

The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by Westinghouse:

Public disclosure of this proprietary infomlation is likely to cause substantial halm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar instrumentation & control systems and licensing defense services for commercial power reactors without commensurate expenses. Also, public disclosure of the iniom1ation would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to lise the information.

The development of the technology described in part by the information is the result of applying the results of many years of experience in an intcnsive Westinghouse effort and the expenditurc of a considerable slim of money.

In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower eilort, having the requisite talent and experience, would have to be expended.
