Holtec International submitted an amendment request to the U.S. Nuclear Regulatory Commission for the HI-STORM Flood/Wind (FW) Multi-purpose Canister (MPC) Storage System, Certificate of Compliance (CoC) No. 1032. The proposed changes include the following:
1)
Add a new unventilated high density (UVH) overpack, HI-STORM 100 UVH, which includes high density concrete for shielding. The UVH is to be used with MPC-37, MPC-89, and MPC-44.
2)
Modify vent and drain penetrations to include the option of second port cover plate.
3)
Allow automated equipment to perform leak test of the MPC materials and welds in the fabrication shop.
4)
Change the hydrostatic pressure test of the MPC acceptance criteria to be examination for leakage only. Remove post hydrostatic test liquid penetrant and magnetic particle examination.
5)
Include the ability to use computational fluid dynamics analysis to evaluate site-specific fire accident scenario.
6)
Use updated methodology for tornado missile stability calculations for freestanding HI-STORMs and HI-TRACs. Clarify the weights to be used for varying heights of HI-TRACs.
7)
Add the new MPC-44, with continuous basket shim (CBS) and to hold 44 pressurized-water reactor fuel assemblies of certain 14x14 fuel class. It is to be used with Version E and UVH overpacks.
8)
Add the new MPC-37P, with CBS and to hold 37 pressurized-water reactor fuel assemblies of certain 15x15 fuel class. It is to be used with Version E overpack.
9)
Add HI-DRIP ancillary system, which is an optional ancillary system designed to prevent water within the MPC from boiling during loading and unloading operations while loading MPC in the HI-TRAC.
10)
Include the ability to use computational fluid dynamics analysis to evaluate site-specific burial-under-debris accident scenario.
11)
Include the ability to use water without glycol in the HI-TRAC water jacket during transfer operations below 32°F based on the site specific MPC total heat loads.
12)
Add new 10x10J fuel type to approved content in the HI-STORM FW system.
13)
Update bounding fuel variables for 8x8F and 11x11A boiling-water reactor fuel types in CoC appendix B.
14)
Other editorial changes.
15)
Adopt a stress-based structural design criterion.
16)
Establish specific criteria on allowable interference due to differential thermal expansion.
