If any basket is found to contain less than 1081 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 1081 pounds / basket at a 95% level of confidence.
The ice condenser shall also be subdivided into 3 groups of baskets, as follows:
Group 1 - Bays 1 through 8. Group 2.-
Bays 9 through 16, and Group 3 - Bays 17 through 24.
The mini-mum 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 1081 pounds / basket at a 95% level of confidence.
The minimum total ice condenser ice weight at a 95% level of confidence shall be calculated using all ice basket weights determined during this weighing program and shall not be less than 2,099,790 pounds; and 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 passages between ice baskets, past lattice frames, and through the intermediate and top deck floor grating is restricted to a thickness of less than or equal to 0.38 inch.
~f one flow passage per bay is found to 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.
c.
At least once per 40 months by lifting and visually inspecting the accessible portions of at least two ice baskets from each one-third of the ice condenser and verifying that the ice baskets are free of detrimental structural wear, cracks, corrosion, or other damage. The ice baskets shall be raised at least 12 feet for this inspection.
d.
- For the lower inlet plenum support structures and turning vanes only, at least once per 18 months, verify, by visual inspection, accumulation of ice or frost on structural members comprising flow l
channels through the ice condenser is less than or equal to 0.38 inch thick.
