RRAS Software Requirements Specification for the Requirements Specification Watts Bar 2 NSSS Completion Program I&C Projects Projects Post Accident Accident Monitoring System SECTION 2 GENERAL DESCRIPTION GENERAL 2.1 FUNCTIONAL DESCRIPTION FUNCTIONAL Watts Bar 2 PAMS, a real-time monitoring system, provides:

• • Information Information and alarms to assist the reactor operators in mitigating plant events or accidents accidents that have the potential to result in inadequate cooling of the reactor core

• 0 Information Information and data to the plant monitoring/safety parameter display system (SPDS) computers monitoring/safety parameter control room display for use in its control The Watts Bar 2 pAMS separate and independent PAMS will be composed of two separate redundant trains. Each of the independent redundant two redundant trains will be capable of performing all of the required required P AMS functions, even if the other PAMS other redundant train is out of service. The overall system availability will comply with the requirements redundant requirements specified in WNA-DS-01617-WBT WNA-DS-01617-WBT (Reference(Reference 17). The PAMS provides two types of indications indications for alarms. The FPDS provides one source ofalarm AC 160 digital outputs to the plant of alarm indication, and the AC160 provide the other alarm indication.

annunciators provide The PAMS measures process input signals, and calculates inadequate core cooling (ICC) functions Of:

Execution order of PCPGM and CONTRM ofPCPGM CONTRM is dependant dependant upon cycle cycle time and priority parameter values.

.The The PCPGM PCPGM or or CONTRM element(s) with CONTRM element(s) with aa shorter cycle time shorter cycle time shall have have priority over other PCPGM or CONTRM CONTRM element(s) element(s) with a longer cycle time. Execution Execution order of the PCPGM or CONTRM CONTRM elements with the same cycle time is based on their respective respective second call parameter (placement parameter (placement in the cycle time

[priority] table). The element with the higher priority (lower number) value will execute execute before an WNA-SD-00239-WBT-NP, Rev. 1 WNA-SD-00239-WBT-NP, 5-2 5-2

element(s). Once execution of of the higher priority PCPGM or CONTRM element(s) is complete, the lower lower priority PCPGM or CONTRM CONTRM element(s) resumes execution.

The following factors should be considered when determining a PCPGM or CONTRM CONTRM cycle time parameter.

• " The CONTRM The CONTRM cycle cycle times times must must be be set set to to aa value value high enough to prevent the processor load from from specified in Requirement R5.1-1.

exceeding the values specified

• • . For For better better sending sending or or receivlng receiving DSP DSP efficiency, efficiency, the cycle times parameters for the CONTRMs CONTRMs that send or receive DSPs should tliat should-be be set equal to that of the PCPGM cycle time. This will ensure that these functions are performed synchronously.

• " When the When the CONTRM CONTRM cycle cycle time parameter parameter and the PCPGM cycle time parameters parameters are equal, inin order to obtain a shorter time response for sending DSPs, the PCPGM priority should be less than that of that of the the CONTRM.

CONTRM. This This allows allows the the DSP values to DSP values to be be written to the Communication Communication Interface (CI) immediately after generation.

• When the When the CONTRM CONTRM cycle time parameter parameter and the PCPGM cycle time parameters parameters are equal, inin order to obtain a shorter time response for receiving DSPs, the PCPGM priority should be greater greater than that than that of of the CONTRM. This the CONTRM. This allows allows thethe DSP DSP values values to to be be received in the CONTRM CONTRM immediately after immediately being received after being received from from thethe CI.

The purpose of the FUNCM FUNCM is to control the arrangement arrangement of the documented documented application code in the FCB.

(ii) The information is ofa of a type customarily held in confidence confidence by Westinghouse and not customarily customarily disclosed disclosed to the public. Westinghouse has a rational basis for determiningdetermining the types of information information customarily customarily held in confidence by it and, in that connection, utilizes a system system to determine determine when and whether to hold certain types of information information in confidence.. The application conl1dence. application of that system system and the substance of that system constitutes Westinghouse policy policy and provides provides the rational basis required.

Under that system, information is held in confidence confidence* if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitivecompetitive advantage, as follows:
