-REFUELING OPERATIONS 3/4.9.11 FUEL HANDLING VENTILATION EXHAUST SYSTEM

~ "

LIMITING CONDITION FOR OPERATION 3.9.11 At.least one train of the Fuel Handling Ventilation Exhaust System shall be OPERABLE.

APPLICABILITY: Whenever irradiated fuel is in the storage pool.

ACTION:

a. With both trains of the Fuel Handling Ventilation Exhaust fystem inoperable, suspend all operations involving movement of fuel within the storage pool or crane operation with loads over the storage pool until the Fuel Handling Ventilation Exhaust System is restored to OPERABLE status. -

b. The provirions of Specification 3.0.3 are not applicable.

SURWILLANCE RECdIREMENTS 4.9.11.1 One train of the Fuel Handling Ventilation Exhaust Syste shall be determined to be operating and discharging through the HEPA fil'P and acti-vated carbon adsorbers at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> whenever irradated fuel is being moved in the storage pool and during crane operation with loads over the storage pool.

4.9.11.2 Both trains of the Fuel Handling Ventilation Exhaust System shall be demonstrated OPERABLE:

a. At least once per 31 days by initiating, from the control room, flow through the HEPA filters and activated carbon adsorbers and-verifying that the system operates for at least 10 continuous hours with the heaters operating;

b. At least once per 1B months or (1) af ter any 'struct Jral maintenance on. the HEPA filter or activated carbon adsorber bo ssings,' or (2) foi-lowing painting, fire, or chemical release in any ventilation zoae communicating with the system by:

l released from the rupture of an irradiated fuel assembly. The minimum water ,

depth is consistent with the assumptions of the safety analysis. ,

P 3/4.9.11 FUEL HANDLING VENTILATION EXHAUST SYSTEM The limitations on the Fuel' Handling Ventilation Exhaust System ensure that all radioactive' material released from an irradiated' fuel assembly will .,

be filtered through the HEPA filters'and activated carbon adsorber prior to l discharge to the atmosphere. Operation of the system with the heaters operat-

• ing to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters. The OPERABILITY of this-system and the result-ing iodine removal capacity are consistent with the assumptions of the safety "

analyses. ANSI N510-1980 will be used as a procedural guide for surveillance testing. 4g73 gg ,, g 4 yg4 ,g iq .j g ,
