1 ENCLOSURE C ERRATA - SCIE-COM-5654-S7, "SCIENTECll,.INC. EVALUATION _OF_
S PENT _EUEL. POOL _ COOLING.SCENARIOSIOR MAINESANKEE" The following represent inaccuracies in the subject report. None of the inaccuracies adversely affect the analysis, results, or conclusions.
1.
On page 2, paragraph one, the first sentence states that there are "1432 complete spent fuel assemblies." There are actually 1431 complete spent fuel assemblies; one assembly had 107 fuel rods removed as a part of a pin consolidation effort 2.
On page 2, paragraph one, the last sentence incorrectly states that there are six unirradiated fuel rods located in the new fuel storage room. The fuel rods have been i
I shipped offsite since issuance of the report.
3.
On page 6, paragraph 3, the second sentence incorrectly states that as of December 1, l
1997 assembly S859 had 355 days of decay. The assembly actually had 360 days of decay.
4.
On page 7, Decay Heat table, five additional days of decay were not accounted for; e.g.
on 1-Dec-97 there had been 360 days of decay, not 355. The decay heat kW values are correct for the d Tys of decay listed; however they correspond to dates five days earlier than those listed in the table.
