If any basket is found to contain less than 1220 pounds of ice, a representative sample of 20 additional baskets from the same bay shall be weighed.

The minimum average weight of ice from the 20 additional baskets and the discrepant basket shall not be less than 1220 pounds/basket at a 95K level of confidence.

The ice condenser shall also be subdivided into 3 groups of baskets, as follows:

Group 1 - bays 1 through 9, Group 2 - bays 9 through16, and Group 3 - baysl7, through 24.

The. minimum average ice weight of the sample baskets from Radial Rows 1, 2, 4, 6, 8 and 9 in each group shall not be less than 1220 pounds/basket at a 95% level of confidence.

The minimum total ice condenser ice weight at a 95K level of confidence shall be calculated using all ice basket weights determined during this weighing program and shall not be less than 2,371,450 pounds.

3.

Verifying, by a visual inspection of at least two flow passages per ice condenser bay, that the accumulation of frost or ice on flow p sages between ice baskets, past lattice frames, thro the intermediate and top deck floor grating, or pas the lower inlet plenum support structures and turnin) vanes is restricted to a. nominal thickness of 3/8 inches.

If one fiow passage.per bay is found to have an accumulation of frost or ice greater.khan this thickness,

. 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 ~y 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.
