DPR-66 INSTRUMENTATION BASES 3/4.3.1 and 3/4.3.2 PROTECTIVE AND ENGINEERED SAFETY FEATURES (ESP) l}iSTRUMENTATION fContinued)
ESF response times which include sequential operation of the RWST and VCT valves are based on values assumed in the Non-LOCA safety analyses and are provided in section 3 of the Licensing Requirements Mandal.
These analyses take credit for injection of borated water.
Initial borated water is supplied by the BIT, however, injection of borstod water from the RWST is assumed not to occur until the VCT charging pump suction valves are closed following opening of the RWST charging pump suction valves.
When sequential operation of the RWST and VCT valves is not ingluded in the response times, the values l
specified are based on the LOCA analyses.
The LOCA analyses take credit for injection flow regardless of the source.
Verification of the response times will assure that the assumptions used for the LOCA l
and Non-LOCA analyses with respect to operation of the VCT and RWST valves are valid.
Response time may be demonstrated by any series of repantial, 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 Engineered Safety Feature Actuation System interlocks perform the followir.g functions:
P-4 Reactor tripped Actuates turbine
- trip, closes main feedwater. valves on Tavg below
- setpoint, prevents the opening of the main feedwater valves which were closed by a safety injection or high steam generator water level signal, allows safety injection block so that components can be reset or tripped.
Reactor not tripped - prevents manual block of safety injection.
P-11' Above the setpoint P-11 automatically reinstates safety injection actuation on low pressurizer
- pressure, automatically blocks steamline isolation on high steam pressure
- rate, enables safety injection and steamline isolation on low steamline pressure (with Loop Stop Valves Open), and enables auto actuation of the pressuriser PORVs.

The methodology to derive _ the trip setpoints is based upon combining _-all of the uncertainties in the channels.
Inherent to the - determination - of the trip ; setpoints are the magnitudes of these channel uncertainties.
Sensor and rack instrumentation utilized in these channels are expected to be capable of operating within the allowances of these uncertainty-magnitudes.
Rack drift in-excess of the Allowable Value exhibits the behavior that the rack has not met its allowance.
Being that. there is a small statistical chance that this will happen, an infrequent excessive drif t --is expected.
Rack or sensor - drift, in excess of: the allowance that is more than occasional, may be indicative of more serious' problems and should warrant further investigation.
The surveillance requirements for the Manual-Trip
- Function, Reactor Trip ' Breakers,- and Reactor Trip Bypass Breakers are provided to - reduce-the possibility of 'an Anticipated Transient Without Scram (ATWS) event by ensuring OPERABILITY of the divene trip features (

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 tiaw limit assumed - in the accident-analyses.
No credit was taken. in _ the analyses for those channels with response times indicated as_not applicable.
ESF response times:which include sequential operation of the RWST.
and VCT valves are based on values-assumed in the non-LOCA safety analyses and are provided-in Section 3
of the _ Licensing Requirements Manual.
Thsse analyses take credit for injection of borated water from the RWST.
Injection of borated water is
- assumed 'not to occur until-the VCT charging pump suction valves are closed following opening.of the RWST charging pump-suction
- valves.
When sequential operation of. the RWST and VCT valves is not included in the response times, the values specified are based l
on the LOCA analyses.
The LOCA analyses take credit for injection flow regardless of the source.
Verification of the response times will assure that the assumptions used for the LOCA and Non-LOCA analyses with respect to operation of the VCT~and RWST valves are valid.
The maximum response time for control room isolation on high radiation is - based on ensuring that the control room remains habitable following a small line brea" outside the containment.
From a control room habitability aspect, the worst case accident that does not initiate a Containment Isolation - Phase B signal is s

the small line break outside the containment.
This response time includes radiation monitor-processing delays - associated with the
- nonitor averaging techniques.
Diecal Generator starting and sequence loading delays are not included since these delays occur prior to the control room environment exceeding the high radiation setpoint.
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 Engineered Safety Feature-Actuation System interlocks perform the following functions:

Actuates; turbine

below setpoint, prevents the opening of the main feedw'ater valves which were closed by a safety injection or high steam generator water level signal, allows safety injection block so -that components can be reset or tripped.
Reactor not tripped prevents manual block of safety injection.
P-11 Above the setpoint, P-11 automatically reinstates safety injection actuation on low pressurizer
- pressure, automatically blocks steamline isolation on high steam pressure rate, and enables safety injection and - steamline isolation (with Loop Stop Valve Open) on low steamline pressure.
Below the setpoint, P-11 allows the manual block of safety injection actuation on low pressurizar

P-12 automatically reinstates an arming signal to t.? e steam dump system.
Below the setpoint P-12 blocks steam dump and allows manual bypass of the steam dump block to cooldown condenser dump valves.

a) routine surveillance testing of other channels, and b) setpoint adjustments of other channels when required-to rednce the setpoint in accordance with other technical specifications.-
The 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> time limit is justified in accordance with WCAP-10271-P-A, Supplement 2,
Revision 1,
June 1990.
Note ' (5) only requires SR 4.2.4 to be performed if a Power Range High Neutron Flux channel input to QPTR becomes inoperable.
Failure of a' component in the Power Range High Neutron Flux channel which renders the High Neutron Flux trip function inoperable may not affect the capability to monitor QPTR.
As such, determining QPTR using the movable incore detectors once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> may not be necessary.
3/4.3.3 -MONITORING-INSTRUMENTATION 3/4.3.3.1 RADIATION MONITORING INSTRUMENTATION The OPERABILITY of the radiation monitoring channels ensures that:
1) the radiation levels are continually measured in the areas served by the individual. channels;: 2) the alarm or automatic
- action is initiated when' the _ radiation level trip setpoint is exceeded; and 3) sufficient information is available on selected plant-- parameters to monitor and assess these variables following an accident.
This capability is consistent with the recommendations of NUREG-0737, " Clarification of TMI Action Plan Requirements," October, 1980.
3/4.3.3.2 MOVABLE INCORE DETECTORS The OPERABILITY of the movable incore detectors with the specified minimum complement of equipment ensures that the measurements.
obtained from use of this system accurately represent-the spatial neutron flux distribution of the reactor core.
The OPERABILITY of this system is demonstrated by irradiating each detector used and y
determining the acceptability of itu voltage curve.
For the purpose of measuring Fg(Z) or Fh, a full incore flux map is used.
Quarter-core flux maps, as defined in WCAP-8648, June 1976, may be used in re-calibration of the excore neutron flux detection system, and full incore flux maps or symmetric incore thimbles may be used for monitoring the Quadrant Power Tilt Ratio when one Power Range Channel is inoperable.
