! i 3.9.11 Two independent spent fuel pool ventilation systems shall be OPERAELE.

APPLICABILITY: Whenever irradiated fuel is in the spent fuel pool.

ACTIO_ N:

a. With one spent fuel pool ventilation system inoperable, fuel movement within the spent fuel pool or crane operation with loads over the spent fuel pool may proceed provided the OPERABLE spent fuel pool ventilation system is in operation and discharging through at least one train of HEPA filters and charcoal adsorbers.

b. With no spent fuel pool ventilation system OPERABLE, suspeed all operations involving movement of fuel within the spent fuel pool or

' crane operation with loads over the spent fuel pool until at least one spent fuel pool ven'.ilation system is restored to OPEAABLE status.
