Engineering Package PC/M 07130 did not allow non-fuel assembly hardware in any of the 192 fuel assemblies selected to be loaded into the six canisters planned for the initial loading campaig The Engineering Package stated that lumped burnable absorber rods (LBAR) displaced fuel rods in certain St. Lucie reload batches and therefore were not considered non-fuel assembly hardwar This was established in Calculation PSL-1FJF-07-002 where the implication of loading CE 14 x 14 fuel assemblies containing lumped burnable absorber rods was evaluate The calculation stated that another calculation, performed by Transnuclear, found that the effects of loading 32 CE-type assemblies, each containing 16 lumped burnable absorber rods, was insignificant relative to the Safety Analysis Report evaluation of criticality, shielding and internal canister pressur Therefore, Calculation PSL-1FJF-07-002 concluded that the existing analyses and analysis assumptions in the Safety Analysis Report remain valid and that the St. Lucie Unit 1 fuel remains bounded by the Safety Analysis Report for CoC 1030 as long as the total number of lumped burnable absorber rods per canister remained below 512 (16 lumped burnable absorber rods/assembly x 32 assemblies/canister).

The requirement to analysis a safe load path does not apply to the use of the new cranes installed at St. Lucie Units 1 and 2 because they are single failure proo However, the removal of the old cranes in 2003 involved the use of a mobile crane during dismantlement of the trolley, bridge, cab and crane structure Because this work effort was near the fuel building and underground cables, and the removal effort involved the heavy lifts of the trolley (90,100 lbs) and bridge (106,890 lbs), the licensee performed an analysis to determine if any impact would occur on safety-related structures, systems and components (SSC). The analysis determined that underground cabling could be impacted from a drop during the dismantlement effor Each of the cables was analyzed to determine the impact of opening or shorting the cable The analysis showed that no safe shutdown function would be adversely affected during the demolition activities.

dated March 5, 2008 Requirement: FSAR Section 5.4.7.1 states that 85% of the neutron spectrum from the spent fuel will be represented by spontaneous fission of Cm-24 While water is in the cask, the neutrons will be adequately thermalized similar to the neutron energy levels typically encountered in the plan However, once the water is removed from the cask, a higher neutron energy spectrum will be emitted from the cas FSAR Table 5-13 provides the design basis neutron energy spectrum for the caniste Since the neutron energy will be higher when the water has been removed from the cask during drying, helium backfill and transport to the ISFSI pad, than the normal thermal energies of neutrons found in work areas of the plant, calibration considerations should be made for personnel monitoring of neutrons at these higher energies.
