l 14.2.12.1.'44-Post'Accadent Monitoring System Insfr I
,/
(1) Purpose J
l To verify the proper operation of post accident monitoring system (PAMS) to provide information for long term monitoring of the drywell and wetwell atmospheres and suppression pool temperature and level during i
both normal operations and accident conditions in the primary containment.
(2) Prerequisites I
ne construction tests have been successfully completed and the SCG has reviewed the test procedure and has i
appmved the initiation of testing. He suppression pool shall be filled and expected to undergo measurable I
level and temperature changes at some point during the scheduled testing. The required interfacing systems atnd.3;ormen_tage zSla'bli anwededa to support the specified testing. Additionally, any parallel testing to be performed in conjunction with the testing of this subsection is appropriately scheduled.
(3) General Test Methods and Acceptance Criteria A description of the instrumentation required for containment monitoring is presented in biaG5312r and' Subsection 7.5 for PAMS. Preoperational testing of these instruments will be performed in conjunction with the testing of the applicable systems. Only that instrumentation associated with the PAMS requiring I
special considerations is discussed below.
Performance shall be observed and recorded during a series ofindividual component and integrated system tests to demonstrate the following:
O (a) proper tracking of drywell pressure by all instrument channels during containment integrated leak rate testing (see Subsection
);
+- & ~ '(. 2.tu.4M a.
(b) proper operation and response of all5phYsn pool level instrumentation during actual changes in pool level; (c) proper operation and tracking of all suppression pool temperature monitoring (SPTM) system instrument channels during actual change in pool temperature-(d) proper functioning of associated indicators, recorders, annunciators, and alarms including those instruments in the main control room and in the remote shutdown panel.
(e) proper outputs to all system components that are required to function upon receiving inputs from the -
PANS instruments at the prescribed high/ low setpoints and inoperative conditions; (f) proper signal processing of the PAMS related instrumentation by the microprocessor as specified by the appropriate design specification; (g) proper operation of drywell and wetwell air temperature and pressure monitoring subsystem instrumentation.
System operation is considered acceptable when the observed / measured performance characteristics, from the testing described above, meet the applicable design specifications.
