After reinsta11ation of the sampled adsorber tray, per C.1:
4 (a) Verify that the charcoal adsorbers remove 199.5 percent of a htlogenated hydrocarbon refrigerant test gas when they are tested in-place in accordance with ANSI N510 while operating the filter train at a stabilized flow rate of at least 2880 CFM but no greater than 3520 CFM.
(b) Verify that the HEPA filter bank removes 199.9 percent of the DOP when tested in-place in accordance with ANSI N510 while operating the filter train at a stabilized flow rate of at least 2880 CFM but no greater than 3520 CFM.
D.
Started on a manual signal and operated for 15 minutes in each 31-day period.
E.
Demonstrated operable at least once per refueling interval or once every 18 months, whichever occurs first, by:
1.
Verifying that on a high radiation signal, the normal system is automatically isolated and that the emergency filtering i
system operates.
2.
Verifying that on a toxic gas (ammonia excluded) isolation signal, the system automatically switches into the isolation mode of operation with flow through the HEPA filters and t
charcoal adsorber banks (only required if the total quantity of gaseous chlorine in the RESTRICTED AREA exceeds 100 pounds).
i 3.
Verifying that the refrigerant system will maintain the Control Room / Technical Support Center temperature at no more than 80'F for at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
)
BM11 The purpose of the Control Room /TSC Emergency Filtering System is to limit the particulate and gaseous fission products and toxic products to which the Control Room area and Technical Support Center would be subjected during an accidental radioactive or chemical release in or near the Auxiliary Building.
The system is designed with two redundant filter trains each of which consists f
of a moisture separator, a heater, a high efficiency particulate filter, two banks of charcoal filters, a second high efficiency particulate filter and a booster fan to pressurize the Control Room and Technical Support Center with outside air.
The prestabilized air flow rate will not exceed 3750 CFH during the 15 minutes preceding stabilized air flow.
