(SURVEILLANCE REQUIREMENTS)

Insert C (UNIT 1 TS 4.7.7.1)

The Auxiliary Building Exhaust air filtration system shall be demonstrated OPERABLE:

1. filter train 11 and carbon adsorber train 14, then
2. filter train 12 and carbon adsorber train 14
b. At least once each 18 months, or (1) following painting, fire or chemical release in any ventilation zone communicating with the system, or (2) any partial or complete replacement of the HEPA or carbon filters, by:
1. Verifying that, with the ECCS duct flow path and HEPA train 11 aligned to carbon adsorber train 14 and operating at a flow rate of 21,400 CFM +/-10%, the total bypass flow is less than or equal to 1% when tested by injecting halogenated hydrocarbon refrigerant in accordance with ANSI N510-1975.
2. Verifying that, with the ECCS duct flow path and HEPA train 12 aligned to carbon adsorber train 14 and operating at a flow rate of 21,400 CFM +/-10%, the total bypass flow is less than or equal to 1% when tested by injecting halogenated hydrocarbon refrigerant in accordance with ANSI N510-1975.

14 removes ;:::99% of a halogenated hydrocarbon refrigerant test gas when tested at 21,400 CFM +/-10% in accordance with Regulatory Guide 1.52 Rev 2, 1978, Section C.5.d.

4. Verifying that, in-place leak testing of HEPA filter banks in trains 11, 12, 13 will remove 99% of DOP when tested at their rated design flow capacity +/-10% for each housing in accordance with Regulatory Guide 1.52 Rev 2, 1978, Section C.5.c.
5. Verifying within 31 days after removal that laboratory analysis of a representative carbon sample demonstrates a removal of
90% methyl iodine when tested at 30 degree C and 95%

RH in accordance with ANSI 03803 Revision 1989.

6. Verifying that flow rate through the carbon adsorber does not exceed 21,400 CFM +/- 10% when either HEPA+ carbon adsorber combination is aligned to the ECCS areas.

7.a. Verifying the total pressure drop across HEPA train 11 and carbon adsorber train 14 is ::;:;4" Water Gauge when tested at 21,400 CFM +/-10%.

7.b. Verifying the total pressure drop across HEPA train 12 and carbon adsorber train 14 is ::;:;4" Water Gauge when tested at 21,400 CFM +/-10%.

8. Verifying that, with HEPA train 11 aligned to the carbon adsorber 14 and HEPA train 12 aligned to the normal area duct, the system can maintain the Auxiliary Building at a slight negative pressure with respect to outside ambient pressure.

d. After maintenance affecting the flow distribution, verify that the airflow distribution of the system is acceptable when tested in accordance with Regulatory Guide 1.52, Revision 2, 1978 Section C.5.b.
e. After any structural maintenance on the HEPA or carbon adsorber unit mounting frames or housing, perform tests as required by surveillance 4.7.7.1.b.1through4.7.7.1.b.4.
f. After operation of Auxiliary Building. normal flow path through the carbon adsorber, prior to mode 4 entry, verify the carbon adsorber will remove ~99% of a halogenated hydrocarbon refrigerant test gas when in-place leak tested at a flow rate of 21,400 CFM +/-10%.
g. After operation of containment purge exhaust flow path through the carbon adsorber, prior to mode 4 entry, verify the carbon adsorbers will remove ~99% of a halogenated hydrocarbon refrigerant test gas when in-place leak tested at a flow rate of 21,400 CFM +/-10%.
