With one broad range gas detection system inoperable, restore the inoserable detection system to OPERABLE status within 7 days or wit 11n the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> initiate and maintain operation of the control room ventilation system in the isolate mode of operation, b.
With no broad range gas detection system OPERABLE, within I hour initiate and maintain operation of the control room ventilation system in the isolate mode of opera' ion, c.
The provisions of Specification 3.0.4 are not applicable.
SURVElllANCE RE0VIREMENTS 4.3.3.7.3 Each broad range gas detection system shall be demonstrated OPERABLE by performance of a CHANNEL CHECK at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, a CHANNEL FUNCTIONAL TEST at least once per 31 days, and a channel calibration at least once per 1 days. Calibration will consist of the introduction of a standard gas and adjusting the instrument sensitivity based on the calibration gas relationship of the standard gas to the calibrating gas.

o INSTRUMQlTATION BASES 3/4.3.3.6 ACCIDENT MONITORING INSTRUMENTATION The OPERABILITY of the accident monitoring instrumentation ensures +'.at sufficient information is available on selected plant parameters to me.sitor 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 h0 REG-0737, "THI Action items."
Table 3.3.10 includes most of the plant's RG 1.97 Type A and Category 1 variables.
The remaining Type A/ Category I variables are included in their respective specifications.
Type A variables are included in this LCO because they provide the primary information required to permit the control room operator to take specific manually controlled actions, for which no automatic control is provided, that are required for safety systems to accoglish their safety f nctions for Design Basis Accidents (DBAs).
Category I variable:; are the key variables deemed risk significant because they are nee 6d to:
(1) Determine whether other systems important to safety are performing their intended functions; (2) Pro,ide information to the o>erators that will enable them to determine the potential for causing a gross areach of the barriers to radioactivity release; and (3) Provide information regarding the release of radioactive materials to allow for early indication of the need to initiate 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 Channels 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 experience and takes into account the remaining OPERABLE channel (or in the case of a Function that has only one required 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 A01 is not met, a Special Report approved by PORC is required to be submitted to the NRC within the 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 information provided by this instrumentation. Also, alternative Actions are identified before a loss of functional capability condition
- o. Curs.
With the number of OPERABLE accident monitoring channels 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 a'i.ernate means to obtain the required information.
Continuous operation with less than the Minimum Channels OPERASLE requirements is not acceptable because the alternate indications may not fully meet all performance qualification requirements applied to the accident WATERFORD - UNIT 3 B 3/4 3-3 Amendment No. 14,20,49r122
INS 1RUMENTAT10N RASES monitoring instrumentation. Therefore. requiring restoration of one i
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 i
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 sysh.w.
TS 3/4.3.3.6 applies to the following instrumentation:
ESFIPI6750 A, ESFIPR6750 B. ESFIPR6755 A&B, RC 1T10122 NA, RC 1T10112 HB, RC IT10122 CA, RC 1T10112 CB, RC IPI0la2 A,B,C,&D, RC IL10llo X&Y, SG ILilll3 A,B,C,&D, SG ILill23 A,B,C,&D, SG llli!!5 A2&B2, SG ILill25 A2&B2, $1 ILl7145 A, i

j 3/4.3.3.7 CHEMICAL DETECfl0N SYSTEMS The chemical detection systems are the_ chlorine-and broad range toxic gas detection systems.
The OPERABILITY of the chemical detection systems ensures thu 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-2 lenses 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 operates on the principal of gas photoionization, and therefore, the system is sensitive to a broad range of gases.* The system is therefore sersitive to both atmospheric and chemical composition normal fluctuations affecting the Waterford 3 site. The setpoint for the system is thus based on testing and operating experience, and the setpoint is set at the lowest achievable IDLH gas concentration providing rellat'le operation and the optimum detection of toxic gases. The setpoint is i
therefore subject to change wherein necessitated by operating experience such as a result of changes in the Waterford 3 area chemical atmospheric profile.
The setpnint is established-and controlled by procedure.
