Subject:

Holtec International HI-STORM FW Multipurpose Canister Storage system Amendment Request 1032-7

Dear Ms. Kock:

We request DSFMs review of LAR#7 for our HI-STORM FW system which adds heat load patterns to facilitate efficient decommissioning of a nuclear plant planning to shut down. The proposed changes include a new heat load pattern for the MPC-89. The limited scope of this submittal is reflected in the extent of required changes to the FSAR, a summary of which is contained in Attachment 1. The proposed changes do not reduce any of the safety metrics including the computed margins of safety, operational flexibility or radiation protection features imbedded in the HI-STORM FW system. The new pattern follows the same thermal and shielding methodology already reviewed by the NRC under other amendments.

Based on the extremely limited scope, Holtec is requesting that this amendment be effective for use within 14 months. contains changes for the CoC and its appendices. Attachments 3 and 4 provide the proposed changed pages of the HI-STORM FW FSAR, which supports the LAR, in proprietary and non-proprietary versions. All proposed changes are provided in mark-up format to facilitate the Staffs review. Note that the marked changes are only those associated with LAR 1032-7.

Changes associated with previous amendments or revisions to amendment, up to and including HI-STORM FW Amendment 5, are included but not marked as changes, since that LAR request is already under NRC review.

Since these calculation packages are considered proprietary, Attachment 7 contains an affidavit in accordance with 10CFR2.390 requesting that the information be withheld from public disclosure.

Please contact at me (856) 797-0900 ext. 3951 if you have any questions.
