~DECAY H AT A.
The decay heat calculated for long term spent fuel assemblies stored in the spent fuel pool (SFP) as of June 24, 2010 is 14, 117,944 BTU/HR, as shown in Holtec report HI-951389 on page 6.
Provide a detailed list of the individual values of heat generation for each batch (lA-24A and 1B-19B),
as shown in Tables 1 and 2 of this Holtec report.
B.
The list should contain an explanation of the bases for each calculation.
You show batches 10B through 20B to have bur nups of 64,800 (assumed to be NWD/HTe).
Explain whether you use this burnup to calculate heat generation rates for Unit 2 batches.
In any case, explain and justify the burnups you did use for these batches if not contained in the response to lA above.
C.
Explain the marked difference in heat generation for the "Old" batches residing in the SFP calculated in Holtec Report HI-941183, dated August 1994 (pages 2-4) in the amount of 18. 15 E06 BTU/HR versus that calculated in Holtec Report HI-951389 for the updated Thermal/Hydraulic Analysis (Rev. 1,. dated December 22, 1995),
on page 6, of 14. 118 E06 BTU/HR.
D.
Provide the units for the column headings "Burnup", "Enrich", and "Weight" in Table 1 and 2 of Holtec Report HI-951389 if not already contained in response to 1A, above.
2.
DE IONIZER RESINS Explain how the deionizer resins are protected in the event of high SFP coolant temperatures.
