j ., 3.15.3 AUXILIARY AND FUEL HANDLING BUILDLNG AIR TREATMENT SYSTEM Applicability Applies to the Auxiliary and Fuel Handling Building Air Treatment System.

j Obiective To specify the minimum availability and efficiency for the Auxiliary and Fuel Handling i Building Air Treatment System.

Snecification i  ? 15.3.1 The Auxiliary and Fuel Handling Building air Treatment System including both

!' pairs of exhaust fans (AH-E14A&C and AH-E14B&D) and all four banks of exhaust filters (AH-F2A, B, C and D) shall be operable at all times (except as provided in 3.15.3.3) during power operation, and one pair of exhaust fans shall be operating whenever TMI-l irradiated fuel handling operations in the Fuel Handling l Building are in progress.  !

w l 3.15.3.2 The Auxiliary and Fuel Handling Building Air Treatment System is operable when

{ its surveillance requirements are met and:

I a. The results of the in-place DOP and halogenated hydrocarbon tests at design I

flows on HEPA filters and charcoal adsorber banks shall show <0.05% DOP penetration and e0.05% halogenated hydrocarbon penetration, except that the DOP test will be e nducted with prefilters installed.

)

b. The results of laboratory carbon sample analysis shall show 2.90% radioactive methyl iodide decontamination efficiency when tested at 30"C,95% R.H.
c. Each pair of fans (AH-E14A&C and AH-E14B&D) shall be shown to operate l within the range 100,580 CFM to 130,691 CFM (design flow is specified as 118,810 CFM).

3.15.3.3 a. With one pair of Auxiliary and Fuel Handling Building Air Treatment System exhaust fans (AH-E14A&C or AH-E14B&D) inoperable:

1. Verify that the redundant pair of exhaust fans is OPERABLE, in operation, and discharging through all four banks of HEPA filters and charcoal i adsorbers within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, except as provided in 3.15.3.3.b.

)

2. Irradiated fuel handling operations in the Fuel Handling Building may continue provided the redundant pair of exhaust fans is OPERABLE, in operation, and discharging through all four bank of HEPA filters and charcoal adsorbers.

3-62c Amendment No. 55, 76, 122, 177

i =q  !

3.15.3 AUXILIARY AND FUEL HANDLING BUILDING AIR TREATMENT SYSTEM i (Contd.)  !

i j b. With the Auxiliary and Fuel Handling Building Air Treatment System l inoperable:

1. During power operation, restore at least one pair of exhaust fans to operable l condition discharging through all four banks of HEPA filters and charcoal j adsorbers within 7 days or prepare and submit a special report to the NRC j within the next 30 days outlining the actions taken to restore operability and )

l the plans and schedules for restoring the system to operable status.

l

! 2. Handling of irradiated fuel in the Fuel Handling Building shall be suspended l immediately until such time that at least one pair of fans and all four banks l

of exhaust filters is operable and operating. Any fuel assembly movement in progress may be completed.

Bases The Auxiliary and Fuel Handling Building Air Treatment System (Referena 1) is considered to be the 4 banks of exhaust filters (AH-F2A, B, C, and D) and the two pairs of redundant exhaust fans (AH-E14A&C or AH-E14B&D) which take the exhaust air from both the  !

Auxiliary Building and the Fuel Handling Building and discharge it to the Auxiliary and Fuel Handling Building exhaust stack. Exhaust air passes through all of the exhaust filters (AH-F2A, B, C, and D) prior to being discharged to the stack whenever either pair of [ i AH-E14 exhaust fans is in operation.

High efficiency particulate absolute (HEPA) filters are installed before the charcoal adsorbers to prevent clogging of the iodine adsorbers for all emergency air treatment systems. The charcoal adsorbers are installed to reduce the potential release of radioiodine to the environment.

If the ef0ciencies of the HEPA filters and charcoal adsorbers are as speciGed, the resulting doses will be less than the 10 CFR 100 guidelines for the accidents analyzed in Chapter 14 of the UFSAR (References 2, 3, and 4), which assumes 90% efficiency.

If the Auxiliary and Fuel Handling Building Air Treatment System is found to be inoperable, all irradiated fuel handling operations in the Fuel Handling Building will be terminated until the system is made operable.

Inplace DOP and halogenated hydrocarbon tests of the filter banks and laboratory tests of carbon samples will meet the guidelines of Regulatory Guide 1.52, Rev. 2.

. 4.12.3 AUXILIARY AND FUEL HANDLING BUILDING AIR TREATMENT SYSTEM 1

Applicability Applies to the Auxiliary and Fuel Handling Building Air Treatment System and associated components.

Obiective l l

To verify that this system and associated components will be able to perform its design function.

SoeciHeation l

4.12.3.1 At least once per refueling interval:

a. The pressure drop across the combined HEPA filter and adsorber banks shall be demonstrated to be less than 6 inches of water at flow rates from 100,580 CFM to 130,691 CFM (design flow is 118,810 CFM).
b. The tests and sample analysis required by Specification 3.15.3.2 shall be performed.

4.12.3.2 Testing necessary to demonstrate operability shall be performed as follows:

a. The tests and sample analysis required by Specification 3.15.3.2 shall be performed within 30 days prior to the movement of iradiated fuel and following l significant painting, steam, fire, or chemical release in any ventilation zone communicating with the system that could contaminate the HEPA filters or charcoal adsorbers.
b. DOP testing shall be performed after each complete or partial replacement of a HEPA filter bank or after any stmetural maintenance on the system housing that could affect the HEPA filter bank bypass leakage.
c. Halogenated hydrocarbon testing shall be performed after each complete or partial replacement of a charcoal adsorber bank or after any stmetural maintenance on the AH-F2A, B, C, or D housing :M could affect charcoal adsorber bank bypass leakage.
d. The fan combinations AH-E14A&C and AH-E14B&D s' hall be operated at least l 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> every month.

4.12.3.3 An air distribution test shall be performed on the HEPA filter bank after any maintenance or testing that could affect the air distribution within the system. The air distribution across the HEPA filter bank shall be uniform within 120%. The test shall be performed between 100,580 CFM and 130,691 CFM (design flow is 118,810 CFM).

4.12.3 AUXILIARY AND FUEL HANDLING BUILDING AIR TREATMENT SYSTEM (Contd.)

Bases Pressure drop across the combined HEPA filters and charcoal adsorbers of less than 6 inches of water at the system design flove rate will indicate that the filters and adsorbers are not clogged by excessive amounts of foreign matter. Pressure drop should be determined at least once every refueling interval to show system performance capability.

Tests and sample analysis assure that the HEPA filters and charcoal adsorters can perfonn as evaluated. The charcoal adsorber efficiency test procedures should allow for the removal of one adsorber tray, emptying of one bed from the tray, mixing the adsorbent thoroughly and obtaining at least two samples. Each sample should be at least two inches in diameter and a length equal to the thickness of the bed. The in-place test criteria and laboratory test criteria for activated charcoal will meet the guidelines of ANSI N510-1980. If test results are l unacceptable, all adsorbent in the system should be replaced with an adsorbent qualified according to Regulatory Guide 1.52, March 1978 or ANSI N509-1980. Any HEPA filters l found defective should be replaced with filters qualified according to Regulatory Guide 1.52, March 1978 or ANSI N509-1980. l If significant painting, steam, fire, or chemical release occurs such that the HEPA filter or charcoal adsorber could become contaminated from the fumes, chemicals or foreign material, the same tests and sample analysis shall be perfonned as required for operational use. The detennination of what is significant shall be made by the Director Operations and Maintenance, TMI.

Operation of the Auxiliary and Fuel Handling Building Exhaust Fans each month for at least ten (10) hours will demonstrate operability of the fans.
