If a helium cask environment cannot be achieved and maintained, fuel clad temperatures may increase beyond the analyzed condition.

Therefore, the cask will be required to be placed back into the spent fuel pool within 7 days and re-flooded.

This time is sufficient time to return the cask to the spent fuel pool and re-flood the cask cavity.Once placed in the spent fuel pool, the fuel is provided adequate decay heat removal to maintain the loaded fuel within limits.SURVEILLANCE SR 3.1.2.1 REQLUREMENS This Surveillance is modified by a Note. The Note clarifies that meeting the Surveillance is not required, and thus there is not a failure to meet the LCO per SR 3.0.1 and SR 3.0.4 does not apply, prior to the specified Frequency.

While, the effective thermal conductivity of the cavity gas is not dependant upon pressure, it is dependant upon the make-up of the gases within the cask cavity. Thermal analyses have shown that maximum fuel cladding temperature limit of 752°F is not exceeded during LOADING OPERATIONS provided a 75% helium environment (based on partial pressure) is established within the cask. Thus, design basis heat removal requirements will be satisfied provided an environment of at least 75% helium has been established, and maintained in the cask cavity within the 34 hour3.935185e-4 days <br />0.00944 hours <br />5.621693e-5 weeks <br />1.2937e-5 months <br /> vacuum drying time frame (Reference 3).SR 3.1.2.2 This Surveillance is modified by a Note. The Note clarifies that meeting the Surveillance is not required, and thus there is not a failure to meet the LCO per SR 3.0.1, and SR 3.0.4 does not apply prior to the specified Frequency.

Evacuating the cask cavity to the specified vacuum prior to pressurization (see SR 3.1.2.3) will ensure that the amount of oxidizing gases remaining in the cavity will be no greater than Prairie Island ISFSI B 3.1.2-4 Revision 10 Cask Helium Backfill Pressure B 3.1.2 SURVEILLANCE REQUIREMENTS (continued) 0.25% (volume).

Below this concentration, degradation of stored cladding and fuel materials is not expected.SR 3.1.2.3 This Surveillance is modified by a Note. The Note clarifies that meeting the Surveillance is not required, and thus there is not a failure to meet the LCO per SR 3.0.1 and SR 3.0.4 does not apply, prior to the specified Frequency.

The long-term integrity of the stored fuel is dependent on storage in a dry, inert environment and maintenance of adequate heat transfer mechanisms.

Filling the cask cavity with helium at the initial pressure, following the evacuation in SR 3.1.2.2, will ensure that the amount of oxidizing gases remaining in the cavity will be no greater than 0.25% (volume).

At this concentration, degradation of stored cladding and fuel materials is not expected.

Also, maintaining pressure below the upper limiting value will ensure that cask cavity internal pressure will remain within limits for the life of the cask.Backfilling with helium at a specified pressure must be performed successfully on each cask prior to performance of leak testing activities and TRANSPORT and STORAGE OPERATIONS.
