}

ACTUAT ON SYS" EMS LMSTRUMENTATION T'he OPERABILITY of the Reactor Protective and Engineered Safety Features Actuation Systems instrumentation and bypasses ensures that (1) the associated Engineered Safety Features Actuation action and/or re ctor trip will be initiated when the parameter monitored by each channel or combination thereof reaches its setpoint, (2) the specified coincidence logic is maintained.

(3) sufficient redundancy is maintained to permit a channel to be out of service for testing or maintenance, and (4 capability is aval able from diverse parame)ters. sufficient system functional The OPERA 81LITY of these systems is required to provide the overall reliability, redundancy, and diversity assumed available in the facility design for the protection and mitigation of accident and transient conditions.

The integrated operation of each of these systems is consistent with the assumptions used in the safety analyses.

The redundancy design of the Control Element Assembly calculators (CEAC) l provides reactor protection in the event one or both CEACs become inoperable.

If one CEAC is in test or inoperable, verification of CEA position is performed at least every 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

If the second CEAC fails, the CPCs will use DNBR and LPD penalty factors to restrict reactor operation to some maximum fraction of RATED THERMAL POWER.

If this maximum fraction is exceeded, a i

reactor trip will occur.

The Surveillance Requirements specified for these systems ensure that the overall system functional capability is maintained comparable to the original l

design standards. The periodic surveillance tests performed at the minimum frequencies are sufficient to demonstrate this capability. The quarterly fre-quency for the channel functional tests for these systems comes from the analyses presented in topical report CEN-327: RPS/E5FAS Extended Test Interval Evaluation, as supplemented.

RPS\\ESFAS Trip Satpoints values are determined by means of an explicit setpoint calculation analysis. A Total Loop Uncertainty (TLU) is calculated for each RPS/ESFAS instrument channel. The Trip Setpoint is then determined by adding or subtracting the TLU from the Analytical Limit (add TLU for decreasing process value; subtract TLU for increasing process value). The Allowable Value is determined by adding an allowance between the Trip Setpoint and the Analytical Limit to account for RPS/ESFAS cabinet Periodic Test Errors (fTE) which are present during a CHANNEL FUNCTIONAL TEST.

PTE combines the RPS/ESFAS cabinet reference accuracy, calibration equipment errors (M&TE), and RPS/ESFAS cabinet histable Drift.

Periodic testing assures that actual setpoints are within their Allowable Values. A channel is inoperable if its actual setpoint is not within its Allowable Value and corrective action must be taken. Operation with a trip set less conservative than its setpoint, but within its specified ALLOWA81.E VALUE is acceptable on the basis that the difference between each trip Setpoint and the ALLOWABLE VALUE is equal to or less than the Periodic Test Error allowance assumed for each trip in the safety analyses.

3/4.3 INSTRUMENTATION BASES (Cont'd) 3/4.3.1 and 3/4.3.2 REACTOR PROTECTIVE AND ENGINEERED SAFETY FEATURE ACTUATION SYSTEMS INSTRUMENTATION The measurement of response time at the specified frequencies provides assurance that the protective and ESF action function associated with each channel is completed within the time limit assumed in the safety analyses.

No credit was taken in the analyses for those channels with response times indicated as not applicable.

I

{

Response time may be demonstrated by any series of sequential, overlapping, or total channel test measurements provided that such tests demonstrate the total channel response time as defined.

Sensor response time verification may be demonstrated by either (1) in place, onsite, or offsite test measurements or (2) utilizing replacement sensors with certified response times.

The periodic surveillance tests performed at the minimum frequencies are sufficient to demonstrate this capability.

The quarterly fre-quency for the channel functional tests for these systems comes from the analyses presented in topical report CEN-327: RPS/ESFAS Extended Test Interval Evaluation,. as supplemented.

RPS\\ESFAS Trip Setpoints values are determined by means of an explicit setpoint calculation analysis. A Total Loop Uncertainty (TLU) is calculated for each RPS/ESFAS instrument channel. The Trip Setpoint is then determined by adding or subtracting the TLU from the Analytical Limit add TLU for decreasing process value; subtract TLU for increasing proces(s value).

The Allowable Value is determined by adding an allowance between the Trip Setpoint and the Analytical Limit to account for RPS/ESFAS cabinet Periodic Test Errors (PTE) which are present during a CHANNEL FUNCTIONAL TEST.

PTE combines the RPS/ESFAS cabinet reference accuracy, calibration equipment errors (M&TE), and RPS/ESFAS cabinet bistable Drift.

Periodic testing assures that actual setpoints are within their Allowable Values. A channel is inoperable if its actual setpoint is not within its Allowable Value and corrective action must be taken. Operation with a trip set less conservative than its setpoint, but I

within its specified ALLOWABLE VALUE is acceptable on the basis that the difference between each trip Setpoint and the ALLOWABLE VALUE is equal to or less than the Periodic Test Error allowance assumed for each trip in the safety analyses.

condition within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months . If an inoperable channel of the RWSP - Low or Steam Generator AP EFAS channel is required to be placed in the tripped condition within one hour, then within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months the channel must either be restored to OPERABLE status or be placed in the bypassed condition. The bypassed channel must be restored to OPERABLE status prior to entering thc applicable MODE (S) fo!!owing the next MODE 5 entry. With one of the RWSP - Low or Steam Generator AP (EFAS) channels inoperable and in typass, and testing or repairs is necessary on one of the remaining cha.1nels, ACTION 20 mun m entered.

ACTION 19a is annotated with a 3.0.4 exemption to allow the changing of MODE (S) even though one channelis bypassed. MODE changes between MODES 1 and 4 with this configuration are allowed, to permit maintenance and testing on the inoperable channel. In this configuration, the gpp.g.gg protection system is in a two-out-of-three logic, and the probability of a random failure affecting two of the OPERABLE channels is remote. The tripped condition does not have this annotation as a single failure could cause the Emergency Core Cooling System and Containment Spray System suctions to be supplied from the Safety injection System Sump prematurely and loss of the Low Pressure Safety injection Systems with a premature RAS or with an inadvertent EFAS could cause the automatic isolation of a faulted steam generator from Emergency Feedwater (EFW) to not occur as assumed by the Waterford 3 safety analysis.

Table 3.3-3 ACTION 20 allows for continued operation in the applicable MODE (S) with two of M W M8j the RWSP - Low or Steam Generator AP (EFAS) channels inoperable provided that one of the inoperable channels is bypassed and the other inoperable channel is placed in the tripped condition gpp,gg within one hour.

One of the irioperable RWSP - Low channels must be restored M OPERABLE status within 48 ggp,3g.gy hours to allow removal of the channel from the tripped condition. The allowed time is acceptable p

gg because operating experience has demonstrated the low probability of the following sequence of g

events occurring: the need to place one RWSP - Low channel in the tripped condition while another RWSP - Low channel is in bypass, the receipt of a valid Safety injection Actuation Signal Actuation, M#N#7 and a coincident failure of one of the two remaining OPERABLE RWSP - Low channels. These conditions could cause the Emergency Core Cooling System and Containment Spray System Factions to be supplied from the Safety injection System Sump prematurely due to containment pressure being higher than RWSP outlet pressure and loss of the Low Pressure Safety injection Systems.

One of the inoperable Steam Generator AP (EFAS) channel must be restored to OPERABLE status within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months to allow removal of the channel from the tripped condition. The allowed time is acceptable because operating experience has demonstrated the low probability of the following sequence of events occurrir.g: the need to place one Steam Generator AP (EFAS) channel in the

@58 M tripped condition while another Steam Generator AP (EFAS) channel is in bypass, coincident with a failure of one of the two remaining OPEP.ABLE Steam Generator AP (EFAS) channels, and a Main Steam Line Break (MSLB) or Feedwater Line Break (FLB). These conditions could cause the automatic isolation of a faulted steam generator from Emergency Feedwater (EFW) to not occur as assumed by the Waterford 3 safety analysis.

When one of the inoperable channels is restored to OPERABLE status, subsequent operation ##h59-4 in the applicable MODE (S) may continue in accordance with the provisions of ACTION 19.

h'[

g Because of the in%/ action between process measurement circuits and associated functional units as listed in the ACTIONS 13,14,19, and 20, placement of an inoperable channel of Steam Generator Level in the bypass or trip condition results in corresponding placements of Steam MW#

Generator AP (EFAS) instrumentation. Depending on the number of applicable inoperable channels, the provisions of ACTIONS 19 and 20 and the aforesaid scenarios for Steam Generator AP (EFAS) would govern.

coincident trip logic of one-outef-two taken twice (reactor trip breaker channels A or B, and C or D) are required to produce a trip. Each reactor trip breaker channel consists of two reactor trip breakers. For a reactor trip breaker channel to be considered OPERABLE, both of the reactor trip breakers of that reactor trip breaker channel must be capable of performing their safety function (disrupting the flow of power in its respective trip leg). The safety function is satisfied when the reactor trip breaker is capable of automatically opening, or otherwise opened or racked-out.

If a racked-in reactor trip breaker is not capable of autornatically opening, the ACTION for an inoperable reactor trip breaker channel shall be entered. The ACTION shall not be exited unless the reactor trip breaker capability to automatically open is restored, or the reactor trip breakeris opened or racked-out.
