INSTRUMENTATION BASES 3/4.3.3.6 ACCIDENT HONITORING INSTRUMENTATION The c'f'tABILITY of the accident monitoring instrumentation ensures that sufficient information is available on selected plant parameters to monitor and assess these variables following an accident. The availability of accident monitoring instrumentation is important so that responses to corrective actions can be observed and the need for, and magnitude of, further actions can be determined. These essential instruments are identified by
~'
plant specific documents addressing the recommendations of Regulatory Guide 1.97, as required by Supplement I to NUREG-0737, "THI Action Items."
Table 3.3.10 includes most of the plant's RG 1.97 Type A and Category I variables. The remaining Type A/ Category 1 variables are included in their respective specifications. Type A variables are included in this LC0 because they provide the primary information required to permit the control room operator to take specific manually controlled actions, for which no automatic M
control is provided, that are required for safety systems to accomplish their safety functions for Design Basis Accidents (DBAs).
Category 1 variables are the key variables deemed risk significant because they are needed to:
(1) Determine whether other systems important to safety are per s ming their intended function:,; (2) Provide information to the operators that will enable them to determine the potential for causing a gross breach of the barriers to g
radioactivity release; and (3) Provide information regarding the release of radioactive materials to allow for early indication of the need to initine e
action necessary to protect the public as well as to obtain an estimate of the magnitude of any impending threat.
With the number of OPERABLE accident monitoring channels less than the Required Number of Channals shown in Table 3.3-10, the inoperable channel should be restored to OPERABLE status within 30 days. The 30 day Completion Time is based on operating cxperience and takes into account the <emaining OPERABLE channel (or in the case of a Function that has only one ruuired channel, other non-Regulatory Guide 1.97 instrument channels to monitor the Function), the passive nature of the instrument (no critical automatic action is assumed to occur from these instruments), and the low probability of an event requiring accident monitoring instrumentation during this interval.
If the 30 day A0T is not mot, a Special Report approved by PORC is required to be submitted to the NRC within t % following 14 days. This report discusses the results of the root cause evaluation of the inoperability and identifies proposed restorative Actions. This Action is appropriate in lieu of a shutdown requirement, given the likelihood of plant conditions that would require informatior, provided by this instrumentation. Also, alternative Actions are identified before a loss of functional capability condition occurs.
With the number of OPERABLE accident monitoring clonnels less than the Minimum Channels OPERABLE requirements of Table 3.3-10; at least one of the inoperable channels should be restored to OPERABLE status within 7 days.
The Completion Time of 7 days is based on the relatively low probability of an event requiring PAM instrumentation operation and the availability of alternate means to obtain the required information.
Continuous operation with less than the Minimum Channels OPERABLE requirements is not acceptable because the alternate indications may not fully meet.11 performance qualification requirements applied to the accident 7

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 H0DE 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 l
required plant conditions from full power conditions in an orderly manner and I
without challenging plant systems.
TS 3/4.3.3.6 applies to the following instrumentation:
ESFIPI6750 A, ESFIPR6750 B, ESFIPR6755 A&B, RC IT10122 HA, RC ITIO112 HB, RC ITIO122 CA, RC ITIO112 CB, RC IP10102 A,B,C,&D, RC ILIO 110 X&Y, SG ILI1113 A,B,C,&D,.
SG ILIll23 A,B,C,&D, SG ILIlll5 A2&B2, SG ILI1125 A2&B2, SI ILI7145 A.

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 sufficient 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 re-leases which could pose an actual threat to safety of the nuclear power plant or significantly hamper site personnel in performance of duties necessary for thy 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 *. The system is sensitive to normal fluctuations of both atmospheric and chemical compositior, which affect the Waterford 3 site.
The setpoints associated with the system are based on testing and operating experience.
Set-points are set as to prevent Immediately Dangerous to Life or Health (IDLH) gas concentration in the control room while providing reliable operation and the optimum detectitan of toxic gases.
The setpoint is therefore subject to change wherein necessitated by operating experience such as a result of changes in the Waterford 3 area chemical atmospheric profile. The setpoint is established and cWolled 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 if both channels are
- Including Amononia WATERFORD - UNIT 3 B 3/4 3-3a Amendment No. 14,20,50,104,122,133
e operable and both channels are not performing the check s12ultaneously. The
/,
instrument automatically performs this check. During the time that tne automatic background / reference spectrum check is taking place (which will be less than one minute), the channel will not perform the function of isolation of the control room. -With both channels OPERABLE, the other system will be available to perform the control room isolation function in the event of a toxic gas incident. With one channel taken out of service (e.g., for maintenance), whan the second channel performs the automatic background check, both channels will be unable to perform the function of isolating the control room for the short time of the background check. Analysis has shown that the impact on operator incapacitation and subsequent core damage risk of the-background checks while one monitor is out of service for its 7 day allowed outage time is negligible. Therefore, entry into the ACTION solely due to the automatic 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 approximately one minute on a frequency of once every hour to once every four hours. The exact frequency is established based on operating experience with the instrument.
The performance of the CHANNEL CHcCK once every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> ensures that a gross failure of the instrument has not occurred. The CHANNEL CHECK consists of a~ comparison of the display of the standard gas (utilized in the FUNCTIONAL TEST), 002 and water. 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.
