INSTRUMENTATION BASES monitoring instrumentation. Therefore, requiring restoration of one inoperable channel limits the risk that the variable will be in a degraded condition should an accident occur. If the 7 day requirement is not met, the -
plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
The completion time is reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.
TS 3/4.3.3.6 applies to the following instrumentation: ESFIPl6750 A, ESFIPR6750 B, ESFIPR6755 A&B, RC ITl0122 HA, RC ITl0112 HB, RC ITl0122 CA, RC ITl0112 CB, RC lPl0102 A,B.C,&D, RC IL10110 X&Y, SG ILl1113 A,B,C,&D, SG ILl1123 A,B,C,&D, SG ILl1115 A2&B2, SG ILl1125 A2&B2, Sl ILl7145 A, St ILR7145 B, all CET's, all Category 1 Containment isolation Valve Position Indicators, EFWILig013 A&B, HJTC's, and ENilJ10001 C&D.
3/4.3.3.7 CHEMICAL DETECTION SYSTEMS The chemical detection systems are the chlorine and broad range toxic gas detection systems.
The OPERABILITY of the chemical detection systems ensures that suffmient capability is available to promptly detect and initiate protective action in the event of an accidental chemical release.
The chemical detection systems provide prompt detection of toxic gas releases
'which could pose an actual threat to safety of the nuclear power plant or significantly hamper site personnel in performance of duties necessary for the safe operation of the plant.
~ The broad range toxic gas detection system utilizes a Fourier Transform infrared (FTIR) analysis technique, and therefore, the system is sensitive to a broad range of gases including ammonia. The system is sensitive to normal fluctuations of both atmospheric and chemical composition which affect the Waterford 3 site. The setpoints associated with the system are based on testing and operating experience. Setpoints are set based on control room habitability
- calculations as described in the FSAR, while providing reliable operation rad the optimum detection of toxic gases. The setpoint is therefore subject to chang with operating experience such as a result of chan0es in the Waterford 3 area chemical inventory. The setpoint is established and controlled by procedure.
The LCO and ACTIONS for the broad range gas detection system are annotated such that the system instrument automatic background / reference spectrum check does not constitute system inoperability under the following conditions: (1) both channels are operable and (2) both channels'are not performing the check simultaneously.- The instrument automatically performs the background / reference spectrum check. During the time that the automatic background / reference spectrum check is taking place (which will be two minutes or less),
the channel will not perfonn the function of isolation of the control room. With both channels
' OPERABLE, the other system wili ce available to perform the control room laolation function in s

the event of a toxic gas incident. With one channel taken out of service (e.g., for maintenance),
when the second channel performs the automatic background / reference spectrum check, j
both channels will be unable to perform the function of isolating the control room for the i
short time of the background / reference spectrum check. Qualitative analysis based on a quantitative risk assessment has shown that the impact on operator incapacitation and subsequent core damage risk of the background / reference spectrum check while one monitor is out of service for its 7 day allowed cutage time is negligible. Therefore, entry into the ACTION solely due to the automatic background / reference spectrum check Is not required.
No specific manual CHANNEL CALIBRATION is required as the system instrument performs this function as the background / reference spectrum check automatically for two minutes or less on a frequency of once every hour to once every four hours. The exact frequency is establ-ished based on operating experience with the instrument.
A CHANNEL CHECK is performed once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to compare channel indications of the same parameter. The performance of the CHANNEL CHECK ensures that a gross failure of the instrument has not occurred. Significant deviations from the expected readings and actual readings could be an indication of a malfunction within the unit. The CHANNEL CHECK will detect gross system failure;.thus, it is the key to verifying the instrument continues to operate properly between each CHANNEL FUNCTIONAL TEST.
A CHANNEL FUNCTIONAL TEST is performed to ensure the entire channel will perform its required function. This test includes introduction of a standard gas and verification of isolation of the control room. The time of the occurrence of the background / reference spectrum check is set during the CHANNEL FUNCTIONAL TEST such that both channels are not out of service simultaneously.
