"If the applicant has requested storage of damaged fuel assemblies, ensure that the applicant has adequately described the proposed damage assemblies. If the fuel assemblies are damaged to the extent that reconfiguration of the fuel into a geometry different from intact fuel assemblies can occur, ensure that the applicant provides appropriate [d]ose assessments for normal, off-normal and accident conditions."

the DFI is made of corrosion resistant alloy steel and includes mesh screens or perforated plates at the top and bottom.

for damaged fuel assemblies that can be handled by normal means, the use of a Damaged Fuel Isolator (DFI) (Figure 2.1.7) can be substituted for the use of the DFC.

if used, the DFC or DFI can be installed in those cells where damaged fuel or fuel debris will be positionedstore whose structural integrity has been impaired such that geometric rearrangement of fuel or gross failure of the cladding is expected based on engineering evaluations.

A HI-TRAC VW Version V or V2 containing an MPC loaded with spent fuel assemblies shall NOT be left unattended to insure that blockage of the air flow paths does not occur.A HI-TRAC VW Version V or V2 containing an MPC loaded with spent fuel assemblies shall NOT be left unattended when the MPC does not contain water.

The reviewer should verify that the applicant presents the rationale used to justify the bases for various exposure times, personnel locations relative to the casks (including hot spots), number of personnel required, and appropriate gamma and neutron dose rates. In addition, the reviewer should verify that the calculated doses are consistent with these estimates.As required by 10 CFR 72.236(d), the application must demonstrate that the shielding and confinement features of the cask are sufficient to meet the requirements for real individuals in 10 CFR 72.104, and for DBA conditions in 10 CFR 72.106.

The procedures shall ensure-
