INSTRUMENTATION BASFS REACTOR TRIP SYSTEM AND ENGINEERED SAFETY FEATURE ACTUATION SYSTEM INSTRUMENTATION (Continued)

The verification of response time at the specified frequencies provides l

assurance that the reactor trip and ESF actuation associated with each channel is completed within the time limit assumed in the accident analyses.

Response

time limits for the Reactor Trip System and Engineered Safety Features Actuation System are maintained in Tables 7.2-5 and 7.3-16 of the Parley FSAR, respectively. No credit was taken in the analyses for those channels with response times indicated as not applicable.

Response time may be verified by actual tests in any series of sequential, overlapping or total channel measurements, or by summation of allocated sensor response times with actual tests on the remainder of the channel in any series of sequential or overlapping measurements.

Allocations for specific pressure and differential pressure sensor response times may be obtained from:

(1) historical records based on acceptable response time tests (hydraulic, noise, or power interrupt tests), (2) in place, onsite, or offsite (e.g. vendor) test measurements, or (3) utilizing vendor engineering specifications.

Response time verification for other sensor types must be demonstrated by test.

3/4.3.3 MONITORING INSTRUMENTATION 3 /4. 3. 3.1 RADI ATION 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 and 2) the alarm or automatic action is initiated when the radiation level trip setpoint is exceeded.

Alarm / trip setpoints for the containment purge have been established for a purge rate of 5,000 scfm in all MODES and for purge rates of 25,000 scfm and 50,000 scfm in MODES 4, 5,

and 6.

The containment purge setpoints are based on a release in which Xe-133 and Kr-85 are the predominant isotopes, on concentration values equal to or less than the effluent concentration limits stated in 10 CFR 20, Appendix B (to paragraphs 20.1001-20.2j01), Table 2, 6

Column 1 for these isotopes, and on a X/Q of 5.6 x 10 sec/m at the site boundary.

INSTRUMENTATION DASES RADIATION MONITORING INSTRUMENTATION (Continued)

The alarm / trip setpoint for the fuel storage pool area has been established based on a flow rate of 13,000 scfm; a release in which Xe-133 and Kr-85 are the predominant isotopes, on concentration values equal to or less than the effluent concentration limits stated in 10 CFR 20, Appendix B (to paragraphs 20.g001-30.2401), Table 2, Column 1 for these isotopes, and on a X/Q of 5.6 x 10 sec/m at the site boundary.

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 determining the acceptability of its voltage curve.

For the purpose of measuring F9(Z), FfH, and F a full incore flux map is used.

Quarter-core flux maps, as defined inWCA[-8648, June 1976, may be used in recalibration of the excore neutron flux detection system.

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.

3/4.3.3 MONITORING INSTRUMENTATION 3 /4. 3. 3.1 RADI ATION MONITORING INSTRUMENTATION e

The OPERABILITY of the radiation monitoring channels ensures that 1) the tadiation levels are continually measured in the areas served by the individual j

channels and 2) the alarm or automatic action is initiated when the radiation level trip setpoint is exceeded.

Alarm / trip setpoints for the containment purge have been established for a purge rate of 5,000 scfm in all MODES and for purge rates of 25,000 scfm and 50,000 scfm in MODES 4, 5,

and 6.

The containment purge setpoints are based on a release in which Xe-133 and Kr-85 are the predominant isotopes, on concentration values equal to or less than the effluent concentration limits stated in 10 CFR 20, Appendix B (to paragraphs 20.100}6~sec/m$

I' Column 1 for these isotopes, and on a X/Q of 5.6 x 10 at the site boundary.

1 INSTPUMENTATION BASES RADIATION MONITOP1NG INSTRUMENTATION Continued) 2 The alarm / trip netpoint for the fuel storage pool area has been established based on a flow rate of 13,000 scfm; a release in which Xe-133 and Kr-85 are the predominant isotopes, on concentration values equal to or less than the affluent concentration limits stated in 10 CFR 20, Appendix B (to paragraphs 20.g001-30.2401), Table 2, Column 1 for these isotopes, and on a X/Q of 5.6 x 10 sec/m at the site boundary.

3/4.3.3.2 MOVABLE INCORE QFTECTORS 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 determining the acceptability of its voltage curve.

For the purpose of measuring F9(Z), Ffg, and F, a full incore flux map is used.

Quarter-core flux maps, asdefinedinWCA[-8648, June 1976, may be used in recalibration of the excore neutron flux detection system.

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.
