Four sets of two radiation monitors are provided which initiate the Reactor Building Isolation function and operation of the standby gas treatment system. Four instrument channels monitor the radiation from the refueling area ventilation exhaust ducts and four instrument channels monitor the building ventilation below the refueling floor. Each set of instrument channels is arranged in a 1 out of 2 twice trip logic.

Trip settings of less than 16 mr/hr for the monitors in the refueling area ventilation exhaust ducts are based upon ini-tiating normal ventilation isolation and standby gas treatment system operation so that none of the activity released during the refueling accident leaves the Reactor Building via the normal ventilation path but rather all the activity is processed by the standby gas treatment system.

Two channels of nonsafety-related radiation monitors are provided in the main stack. Trip signals from these monitors are required only when purging the containment through the SGTS and containment integrity is required. The trip signals isolate pri-mary containment vent and purge valves greater than 2 inches in diameter to prevent accidental releases of radioactivity offsite when the valves are open. This signal is added to fulfill the requirements of item II.E.4.2(7) of NUREG-0737.

l Four channels of in-duct radiation monitors are provided L which initiate the Main control Room Emergency Ventilation System.

Each set of instrument channels are arranged in a one (1) out of l two (2) twice trip logic.

Flow integrators are used to record the integrated flow of liquid from the drywell sumps. The integrated flow is indica-tive of reactor coolant leakage. A Drywell Atmosphere Radioactivity Monitor is provided to giv.a supporting information to that supplied by the reactor coolant leakage monitoring system. (See Bases for 1 3.6.C and 4.6.C) l Some of the surveillance instrumentation listed in Table 3.2.F are required to meet the accident monitoring requirements of i

NUREG-0737, Clarification of TMI Action Plan Requirements. This instrumentation and the applicable NUREG-0737 requirements are:

1. Wide range drywell pressure (II.F.1.4)
2. Subatmospheric drywell pressure (II.F.1.4)
3. Wide range suppression chamber water level (II.F.1.5)
4. Main stack wide range gas radiation monitor (II.F.1.1)
5. Vent stack wide range gas radiation monitor (II.F.1.1)
6. Drywell hydrogen concentration analyzer and monitor l (II.F.1.6)
7. 'Drywell high range radiation monitors (II.F.1.3)
