Fuel Handlin in the Auxilia Buildin A licabilit Applies to limitations while moving irradiated fuel in the operating floor area of the auxiliary building.
To limit doses in the event an irradiated fuel assembly is damaged significantly.
S ecification During handling of fuel assemblies in the auxiliary building when either the fuel being handled or the fuel stored in the spent fuel storage pool has decayed less than 60 days since irradiation, the following conditions shall be satisfied:
a
~
b.
c One auxiliary building main exhaust fan shall be opera ting.
The auxiliary building exhaust fan 1C, which takes suction from the spent fuel storage pool
- area, shall. be operating.
All doors,
- windows, and other direct openings between the operating floor area and the outside shall be closed except that the personnel door d.
may be opened for access as required.
Roughing filters shall be installed at the inlet to the adsorbers.

e.
Charcoal adsorbers shall be installed in the ventilation system exhaust from the spent fuel storage pool area and shall be operable.
Radiation levels in the spent fuel storage area shall be monitored continuously.
A load in excess of one fuel assembly and its handling tool shall never be stationed or permitted to pass over storage racks containing spent fuel.
The spent fuel pool temperature shall be limited 'to 150'E'.
'the restriction of 3a11.3 above shall not apply to the movement of cannisters containing consolidated fuel

rods if the spent fuel rack beneath the transported canister contain only spent fuel that has decayed at least bO days since reactor shutdown.
Charcoal adsozbers will reduce significantly the consequen'ces oof a refueling accident which consider th I d f s
e c a
ailure of,a single irradiated fuel assembl y.
Therefore, charcoal adsorbers should be employed whenever recently irradiated fue) is being handled.
This requires that the ventilation system should. be operating and drawing air through the adsozbers.
The only exception to.'the requirement occurs when the fuel being h
dl d
an e
, or any fuel in the storage ol po i has decayed at least 60 days since 1rradzation The consequences of a fuel handling accident in this case"-without operation of the charcoal adsorbers is significantly less than the guidelines of 10CFRI00.3 Amendment No. 5, LS, 12, 19 3.11-2 Amendment No.
The desired air flov, path, when handling irradiated fuel, is from the outside of the building into the operating floor area, toward the spent fuel storage pool, into the area exhaust ducts, through the adsorbers, and out through the ventilation system exhaust to the facility vent. Operation of a main auxiliary building exhaust fan assures that air discharged into the main ventilation system exhaust duct will go through' hEPA and be discharged to the facility vent.
Operation O'f the exhaust fan for the spent fuel storage pool area causes air movement on the operating floor to be toward the pool.
Proper operation of the fans and setting of dampers vould result in a negative pressure on the operating floor vhich vill cause air leakage to be into the building.
- Thus, the overal l air flov is from the location of lov activity (outside the building) to the area of highest activity (spent fuel storage pit)..
The exhaust air flow would be through a
roughing filter and charcoal before being discharged from the facility.
The roughing ilter protects the adsorber from becoming fouled with dirt; the adsorber removes iodine, the isotope of highest radiological signf icance, resulting from a fuel handling accident.
The effectiveness of charcoal for removing iodine is assured by having a high throughput and a high removal efficiency.
The throughput is attained by operation of the exhaust fans.
The high removal efficiency is attained by minimizing the amount of iodine that bypasses the charcoal and having charcoal with a high potential for removing the iodine that does pass through the charcoal.
Amendment tio.

The spent fuel pool temperature is limited to 150'F because if the spent fuel pool cooling system is not at that temperature, sufficient time (approximately 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />) is available to provide backup cooling, assuming the maximum anticipated heat load (full core discharge 6 previously stored fuel), until a temperature of 180'F is,.reached, the temperature at which the structural integrity of the pool was analyzed arid found acceptable.
The requirement of 3.LL5 insures that should a handling accident occur during the movement of a consolidated fuel cannister (as described in 5.4.) the dose at the exclusion area houndary would satisfy the requirements of 10CFR100.
