60845 NRC INSPECTION PROCEDURE IRIB INSPECTION PROCEDURE 60845 OPERATION OF INTER-UNIT FUEL TRANSFER CANISTER AND CASK SYSTEM PROGRAM APPLICABILITY:

IMC 2515C 60845-01 INSPECTION OBJECTIVE This inspection focuses on verifying the licensees operation of an inter-unit fuel transfer canister cask system. This procedure would be used when a licensee is handling and transferring spent fuel between units at their facility.

60845-02 INSPECTION REQUIREMENTS The review shall be performed to determine if: (a) The licensee has developed, implemented, and evaluated preoperational testing activities to safely perform an inter-unit fuel transfer.; (b)

The licensee has developed and made changes to plant programs and procedures to support operations of an inter-unit fuel transfer canister and cask system; (c) activities are accomplished in accordance with the commitments and requirements contained in the Licensing Report (LR),

NRCs Safety Evaluation Report (SER), and the licensee technical specifications (TS); and (d) activities are accomplished in a manner that adhere to As Low As Reasonably Achievable (ALARA) exposure controls practices. This shall be accomplished through direct observation of the dry run and inter-unit fuel transfer activities and by independent evaluation and review of licensee documents.

Requirements and commitments related to preoperational testing and operation of an inter-unit fuel transfer may be found in the licensing basis documents, such as the LR, SER, and TSs. In the event that preoperational test methods and/or acceptance criteria do not coincide with those specified in these documents, the inspector should contact their regional management.

Inspectors should directly observe the preoperational test (dry run) of the inter-unit fuel transfer.

While it is preferable for the dry run to replicate the actual evolution, the use of mockups and overlapping procedures are acceptable. The NRC observed dry run should accomplish the following: (a) demonstrate the functionality of all equipment; (b) test and refine the procedures used for the inter-unit fuel transfer; and (c) demonstrate proficiency by licensee personnel prior to inter-fuel transfer operations.

60845 60845-03 INSPECTION GUIDANCE

a. Inspection Requirement 02.01(a) and 02.02(a). Review and assess the adequacy the licensees procedures. Determine if licensee has completed a verification and validation of the procedures during the dry run. Procedures, including those provided by contractors, should be prepared, reviewed, and approved in accordance with the licensees administrative programs prior to initial loading. During subsequent inspections review changes made to procedures to verify that changes did not reduce the effectiveness of the program and continue to fulfill the commitments and requirements specified in the LR, SER, and TS. Ensure changes were approved consistent with the licensees administrative programs (50.59 process), including reviews required by the plant operations review committee (or similar entity), if applicable.

Procedures should include normal, abnormal, and emergency conditions, such as shielded transfer canister (STC) transfer cask (HI-TRAC) preparation, setup, inspection, fuel loading, HI-TRAC/STC movement, STC fuel unloading, and maintenance and off-normal events (crane operation, water inventory control, transporter breakdown, and cask drop)

b. Inspection Requirement 02.01(b) and 02.02(b). Review the licensees preparation for transfer operations such as ALARA plans, radiological postings, pre-job briefs, training, security and safeguards, survey equipment, equipment staging, lifting equipment, and suitability of the transfer path. Confirm that any personnel assigned to participate in fuel transfer operations have been trained. Through interviews, confirm their knowledge of the safety significant aspects of their job assignments. Ensure changes made to procedures have been properly incorporated into retraining and pre-job briefs.
c. Inspection Requirement 02.02(c). Review the licensees fuel loading plan and confirm that the fuel loading plan meets requirements for configuration of fuel assemblies in the STC. Verify by direct observation and review of records that each fuel assembly transferred meets the conditions for the STC and are appropriately stored in the approved regions within the receiving units spent fuel pool.
d. Inspection Requirement 02.01 (c) and 02.02 (d). Assess the licensees heavy lifting equipment and processes. Refer to NUREG-0612 and ANSI/N14.6-1993 for additional guidance.
