If one flow passage per bay is found to i-have an accumulation of frost or ice with a thickness of greater than or equal to 0.38 inch, a representative sample of 20 additional flow passages from the same bay shall be visually inspected. If these additional flow passages are found acceptable, the surveillance program may proceed considering the single deficiency as unique and acceptable. More than one restricted flow passage per bay is evidence of abnormal degradation of the~ ice condenser.

CONTAINMENT SYSTEMS BASES 3/4.6.5 ICE CONDENSER l
The requirements associated with each of the components of the ice con-denser ensure that the overall system will be available to provide sufficient l
pressure suppression capability to limit the containment peak pressure tran-sient to less than 14.7 psig during LOCA conditions.
3 /4. 6. 5.1 ICE BED The OPERABILITY of the ice bed ensures that the required ice inventory will:
(1) be distributed evenly through the containment bays, (2) contain sufficient baron to preclude dilution of the containment sump following the LOCA, and (3) contain sufficient heat removal capability to condense the Reactor Coolant System volume released during a LOCA.
These conditions are consistent with the assumptions used in the safety analyses.
The minimum weight figure of 1199 pounds of ice per basket contains a 90 l
pound conservative allowance for ice loss through sublimation during the fuel cycle. The minimum total weight of 2,330,856 pounds of ice also contains an additional 1.1% conservative allowance to account for systematic error in the weighing instruments.
l 3 /4. 6. 5. 2 ICE BED TEMPERATURE MONITORING SYSTEM The OPERABILITY of the Ice Bed Temperature Monitoring System ensures that l
the capability is available for monitoring the ice temperature.
In the event the system is inoperable, the ACTION requirements provide assurance that the l
l ice bed heat removal capacity will be retained within the specified time limits.
I 3/4.6.5.3 ICE CONDENSER 000RS The OPERABILITY of the ice condenser doors and the requirement that they be maintained closed ensures that the Reactor Coolant System fluid released during a LOCA will be diverted through the ice condenser bays for heat removal and that excessive sublimation of the ice bed will not occur because of warm air intrusion.
i If an Ice Condenser Door is not capable of opening automatically, then i
system function is seriously degraded and immediate action must be taken to l
restore the opening capability of the door.
Not capable of opening automati-l cally is defined as those conditions in which a door is physically blocked from opening by installation of a blocking device or by obstruction from temporarily or permanently installed equipment.
Impairment by ice, frost or debris is considered to render the doors inoperable but capable of opening i
automatically since these types of conditions will result in a slightly greater torque necessary to open the doors or a slight delay in door opening.
