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 fror ;5e same bay shall be visually inspected. If these additions sow passages are found acceptable, the surveillance program may proceed considering the single defi-ciency 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 18 months by:
1)
Verifying, for the lower inlet plenum support structures and turning vanes only, by a visual inspection, accumulation of ice or frost on structural members comprising flow channels through the ice condenser is less than or equal to 0.38 inch thick.
2)
Weighing a representative sample of at least 144 ice baskets and verifying that each basket contains at least 1199 lbs of ice. The representative sample shall include six baskets from each of the 24 ice condenser bays and shall be constituted of one basket each from Radial Rows 1, 2, 4, 6, 8, and 9 (or from the same row of an adjacent bay if a basket from a designated row cannot be obtained for weighing) within each bay, If any basket is found to contain less than 1199 pounds of ice, a representative sample of 20 additional baskets from the same bay shall be weighed. The minimum average I
weight of ice from the 20 additional baskets and the discrepant basket shall not be less than 1199 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 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 1199 pounds / basket at a 95's 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 2,330,856 pounds.
d.
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.
