UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION REPORT Docket No. 71-9788 Model Nos. S5W Reactor Compartment and 688 Reactor Compartment Disposal Package Certificate of Compliance No. 9788 Revision No. 21
SUMMARY
By letter dated May 8, 2023 (Agencywide Documents Access and Management System Accession No. ML23157A328), Naval Reactors submitted an application for renewal of Certificate of Compliance (CoC) No. 9788 for the Model Nos. S5W Reactor Compartment and 688 Reactor Compartment Disposal Package. In addition, the applicant proposed to remove the NR-1 and S5G reactor compartments as authorized contents because shipments of these submarine classes have been completed. The U.S. Nuclear Regulatory Commission (NRC) staff reviewed the application using the guidance in NUREG-2216, Standard Review Plan for Transportation Packages for Spent Fuel and Radioactive Material." Based on the statements and representations in the application, as supplemented, the staff agrees that these changes do not affect the ability of the package to meet the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 71. The NRC staff concludes that the certificate can be renewed for a five-year term.
1.0 GENERAL INFORMATION The applicant proposed to remove two content types because shipments of these reactor compartments have been completed. The applicant removed all references and descriptive information associated with these reactor compartments from the safety analysis report.
Removal of this information impacted neither the structural, thermal, containment, shielding, criticality nor package operation evaluations performed by the applicant. As a result, the evaluations previously reviewed by the NRC staff remain bounding. Therefore, the NRC staff finds these changes acceptable. Based on a review of the statements and representations in the application, the staff concludes that the package contents have been adequately described to meet the requirements of 10 CFR Part 71.
2.0 STRUCTURAL The staff reviewed the proposed changes and determined that they did not impact the staffs previous safety evaluation report (SER) findings. Therefore, the staff finds that a new evaluation is not needed.
3.0 THERMAL EVALUATION The staff reviewed the proposed changes and determined that they did not impact the staffs previous SER findings regarding the package thermal design. Therefore, the staff finds that a new evaluation is not needed.
2 4.0 CONTAINMENT EVALUATION The staff reviewed the proposed changes and determined that they did not impact the staffs previous SER findings regarding the package containment design. Therefore, the staff finds that a new evaluation is not needed.
5.0 SHIELDING EVALUATION The staff reviewed the proposed changes and determined that they did not impact the staffs previous SER findings regarding the package shielding design. Therefore, the staff finds that a new evaluation is not needed.
6.0 CRITICALITY The staff reviewed the proposed changes and determined that they did not impact the staffs previous SER findings regarding the package criticality design. Therefore, the staff finds that a new evaluation is not needed.
7.0 PACKAGE OPERATIONS The staff reviewed the package operations procedures using the guidance in NUREG-2216 and found them to be adequate. Based on a review of the statements and representations in the application, the staff concludes that the operating procedures meet the requirements of 10 CFR Part 71 and that these procedures are adequate to assure the package will be operated in a manner consistent with its evaluation for approval.
8.0 ACCEPTANCE TESTS AND MAINTENANCE PROGRAM REVIEW The staff reviewed the maintenance procedures for the package using the guidance in NUREG-2216 and found them to be adequate. Based on a review of the statements and representations in the application, the staff concludes that the maintenance procedures meet the requirements of 10 CFR Part 71 and that these procedures are adequate to assure the package will be maintained in a manner consistent with its evaluation for approval.
CONDITIONS The CoC includes the following condition(s) of approval:
Condition 5(a)(1) was revised to remove references to the NR-1 and S5G reactor compartments.
Condition 5(a)(2) was revised to remove references and information associated with the NR-1 and S5G reactor compartments.
Condition 5(b) was revised to remove references to the NR-1 and S5G reactor compartments.
Condition 6 was revised to remove maximum liquid information associated with the NR-1 and S5G reactor compartments.
Condition 15(a) was revised to reflect the new safety analysis report chapter title.
3 Condition 17 was revised to reflect the new expiration date.
The references section has been updated to include this request.
Minor editorial and formatting changes were made.
