Verifying, by visual inspection of a representative random sample of at l

least 54 flow passages (33 percent) per ice condenser bay, that the j

accumulation of frost or ice on flow passages between ice baskets, past lattice frames, through the intermediate and top deck floor grating, or a

i j

past the lower inlet plenum support structures and turning vanes is less i

than or equal to 15-percent blockage of the total flow area in each bay, j

with a 95-percent level of confidence.

]i If the summation of blockage from the sample falls to meet the acceptance criteria, then 100 percent of the passages of that bay snall be j

inspected.

If the 100-percent inspection falls to meet the acceptance criteria, then the flow passages shall be cleaned to meet the acceptance i

i criteria.

Each flow passage that is cleaned will be reinspected. Any

[

i inaccessible flow passage that is not inspected will be considered blocked.
