REQUEST FOR ADDITIONAL Iif0RMATION SPENT FUEL POOL CAPACITY EXPANSION EDWIN I. HATCH NUCLEAR PLANT UNITS 1 AND 2 l.
For our evaluation of the differeace between the maximum calculated koo of 0.87 given in your submittal and the maximum actual keft that might occur in the spent fuel pool, the following information should be provided:
a.
The quantity and distribution of the uranium-235 in the fuel pool storage lattice tilculation for this maximum koo.
b.
The quantity and distribution of gadolinium-155 and gadolinium-157 in the fuel pool storage lattice calculation for this maximum koo.
t c.
The quantity and distribution of the fiss'.cn products and actinides in the fuel pool storage lattice calculation for this maximum koo.
2.
On page 7-3 of your submittal you state, The results in Table [7-1 show that the nominal pitch (Case 2) has a higher koo result than the.
minimum pitch case (Case 6)."
Sir ce the statistical error bounJs given on Table 7-1 do not preclude the opp ' site cor.clusion, a.d since all other calculations for similar storage lattices show the opposite to be true, provide a justification.for this conclusion.
