h 3.15.3 AUXILIARY AND FUEL HANDLING BUILDING AIR TREATMENT SYSTEM Applicability Applies to the Auxiliary and Fuel Handling Building Air Treatment System.
Objective To specify the minimum availability and efficiency for the Auxiliary and Fuel Handling Building Air Treatment Systen.
Specification
'3.15.3.1 The Auxiliary and Fuel Handling Building Air Treatment System including both pairs of exhaust f ans (AH-E14A, B, IL and D) and 4 banks of exhaust filters (AH-F2A, B, C, and D) shall be operable at all times during power opera. tion, except as provided in 3.15.3.3 l
and spe,cified in 3.22.2.4.
3.15.3.2 The Aux'iliary and Fuel Handling. Building Air Treatment System is operable when its surveillance requiremnts are met and:
a.
The results of the in-place 00P and halogenated hydrocarbon tests at design flows on HEPA filters and charcea.1 adsorber i
banks shall show <0.05% DOP penetration and <0.05% halogenated hydrocarbon penetration, except that the 00P test will be conducted with prefilters installed, b.
The results of laboratory carbon sample analysis shall show
>90% radioactive methyl iodide decontamination ef ficiency when Tested at 30*C, 95% R.H.
l c.
Each set of fans AH-E-14 A & C and AH-E-14 8 & D shall each be shown to operate within 11,881 CFM of design flow t
(118,810 CFM).
3.15.3.3 a.
With one pair of Auxiliary and Fuel Handling Building Air Treatment System exhaust f ans ( AH-E14A and C or AH-E148 and D) inoperable, verify that the redundant pair of exhaust fans is in operation and discharging through its HEPA filters and 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.
b.
From the date that the Aux,iliary and Fuel Handling Building Air Treatment System becomes inoperable for any reason during power operation, the system (at least one pair of exhaust fans discharging through i.ts HEPA filters and charcoal 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 s ta tu s.
3-62c Amende nt No. 66, 16,122
Bases The Auxiliary and Fuel Handling Building Air Treatment System is considered to be the 4 banks of exhaust filters (AH-F2A, B, C, and D) and the two sets of redundant exhaust fans (AH-E-14A and C or AH-E14B and D) which take the exhaust air frma 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. set of 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 cmergency air treatment systems. The charcoal adsorbers are installed to reduce the potential release of radioiodine to the environment.
If the efficiencies of the HEPA filters and charcoal adsorbers are as specified, the resulting doses will be less than the 10 CFR 100 guidelines for the accidents analyzed in Chapter 14 of the FSAR, which assumes 90%
efficiency. Mitigation of Fuel Handling Accidents is provided by the Fuel Handling Building ESF Air Treatment System and does not depend on the operation of the Auxiliary and Fuel Handling Building Air Treatment System.
The Auxiliary and Fuel Handling Building Air Treatment System is isolated by automatic damper actuation in the event of increasing activity in the Fuel Handling Building as sensed by radiation monitors.

One train shall be operating continuously whenever THI-1 irradiated fuel handling operations in the FHB are in progress.
a.
With one train inoperable, irradiated fuel handling operations in the Fuel Handling Building may continue provided the redundant, train is operating.
With both trains inoperable, handling of irradiated fuel in b.
the Fuel Handling Building shall be suspended until such time that at least one train is operable and operating. Any fuel assembly mnvement in progress may be completed.

TABLE NOTATION
- At all times.
During waste gas holdup system operation.
Operability is not required when discharges are positively controlled through the closure of WDG-V47, and RM-A8 and FT-151 are operable.
During Fuel Handling Building ESF Air Treatment System Operation.
l (1)
The CMANNEL TEST shall also demonstrate that automatic isolation of this pathway for the Auxiliary and Fuel Handling Building Air Treatment System, I
the supply ventilation is isolated and control room alarm annunciation occurs if the following condition exists:
1.
Instrument indicates measured levels above the high alarm / trip setpoint.
(Includes circuit failure) 2.
Instrument indicates a down scale failure.
(Alarm function only)
(Includes circuit failure) 3.
Instrument controls moved from the operate mode.
(Alarm function only)
(2)
The CHANNEL TEST shall also demonstrate that control room alarm annunciation occurs if any of the following conditions exist:
1.
Instrument indicates measured levels above the alarm setpoint.
(Includes circuit failure) 2.
Instrument indicates a down scale failure (Includes circuit failure) 3.
Instrument controls moved from the operate mode.
(3)
The initial CHANNEL CALIBRATION for radioactivity measurement instrumentation shall be performed using one or more of the reference standards certified by the National Bureau of Standards o: using standards that have been obtained from suppliers that participate in measurement assurance activities with NBS. These standards should permit calibrating the system over its intended range of energy and measurement range. For subsequent CHANNEL CALIBRATION, sources-that have been related to the initial calibration should be used.
(Operating plants may substitute previously established calibration procedures for this requirement.)
(4)
The CHANNEL CALIBRATION shall include the use of standard gas samples containing a nominal:
1.
One volume percent hydrogen, balance nitrogen, and 2.
Four volume percent hydrogen, balance nitrogen.

Samples shall be changed at least once per 7 days and analyses shall be completed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> af ter changing (or af ter removal from sampler),
e.
Tritium grab samples shall be taken weekly from the ventilation exhaust from the spent fuel pool area whenever spent fuel is in the spent fuel pool.
f.
The ratio of the sample flow rate to the sampled stream flow rate shall be known for the time period covered by each dose or dose rate calculation made in accordance with Specifications 3.22.2.1, 3.22.2.2, and 3.22.2.3.
g.
The principal gamma amitters for which the LLD specification applies exclusively are the cIlowing radionuclides: Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135 and Xe-138 for gaseous emmissions and Mn-54, Fe-59, Co-58, Co-60, 2n-65, Mo-99, Cs-137, Ce-141 and Ce-144 for particulate
+
emissions. This list does not mean that only these nuclides are to be detected and reported.
Other peaks which are measurabl~e and' identifiable, together with the above nuclides, shall also be identified and reported. Nuclides which are below the LLD for the analyses shall be reported as "less than" the nuclide's LLD, and shall not be reported as being present at the LLD level for that nuclide. The "less than" values shall not be used in the required dose calculations.
h.
Applicable only when condenser vacuum is established. Sanpling and analyses shall be performed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> following each shutdown, startup or thermal power level change exceeding 15% of Rated Thermal Power in one hour.
i.
Gross Alpha, Sr-89, and Sr-90 analyses do not apply to the Fuel Handling Building ESF Air Treatment System.
