4 3'.15.3 AUilLIARY AND FUEL HANDLING BUILDING AIR TREATMENT SYSTEM App 1icability 1
l Applies' to the Auxiliary and Fuel Handling Building Air Treatment System.
i Obiective To specify the minimum availability and efficiency for the Auxiliary and Fuel l
Handling Building Air Treatment System.
Specification 3.15.3.1 The Auxiliary and Fuel Handling Building Air Treatment System including two pairs of exhaust fans (AH-E-14 A & B and AH-E-14 C &
I D) and four banks of exhaust filters (AH-F2A, B, C and D) shall be operable at all times during power operation, except as provided in 3.15.3.3 and specified in 3.22.2.4.
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 flows on HEPA filters and charcoal adsorber banks shall show <0.05% DOP penetration and <0.05%
halogenated hydrocarbon penetration, except that the D0P test will be conducted with prefilters installed.
b.
The results of laboratory carbon sample analysis shall show 290% radioactive methyl iodide decontamination efficiency when tested at 30*C, 95% R.H.
c.
Each set of fans (AH-E-14 A & C and AH-E-14 B & D) shall be shown to operate within the range 100,580 CFM to 130,691 CFM (design flow is specified as 118,810 CFM).
l l
3.15.3.3 a.
With one pair of Auxiliary and Fuel Handling Building Air l
Treatment System exhaust fans (AH-E14A and C or AH-E14B and D) inoperable, verify that the redundant pair of exhaust fans is in operation and discharging through its HEPA filters and l
charcoal 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.
I 1
b.
From the date that the Auxiliary and Fuel Handling Building l
Air Treatment System becomes inoperable for any reason during power operation, the system (at least one pair of exhaust fans discharging through its HEPA filters and charcoal l
adsorbers) must be restored to operable condition within 7 days.
If the system is not restored to operable within 7 days, prepare and submit a special report to the NRC within the next 30 days outlining the actions taken to restore operability and the plans and schedules for restoring the system to operable status.
