SAFETY EVALUATION REPORT Docket No. 71-9309 Model No. RAJ-II Package Certificate of Compliance No. 9309 Revision No. 14
SUMMARY
By letter dated July 14, 2023 (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML23191A150), the U.S. Nuclear Regulatory Commission staff (the staff) issued Certificate of Compliance (CoC) USA/9309/B(U)F-96, Revision No. 13, to allow for the transportation of GNF 10x10 fuel assemblies with enrichments up to 8 weight percent (wt.%)
235U.
The issuance of CoC Revision No. 14 corrects an inadvertent error, found in table Nos. 3 and 5 of the CoC, and deletes an underline below the words 5 wt.%. No other changes were made.
EVALUATION
Table No. 3 showed GNF 10x10 fuel assemblies with an enrichment of 8 wt.% 235U. This error occurred when table No. 3 Fuel Assembly Parameters was split, for clarity reasons, into two tables (table 3 for CSI=1.0 and table 4 for CSI =1.6). Specifically, in table No. 3 (CSI=1.0), the 235U Pellet Enrichment and Lattice Average Enrichment is 5.0 wt.% for GNF 10x10; it is 8.0 wt.% in table No. 4 for CSI = 1.6.
Table No. 5 of the CoC included two rows for Polyethylene Equivalent Mass per Compartment.
The first row was no longer consistent with table 6-2 of the application and was deleted for clarity. The second row was not modified. An inadvertent underline for the words 5 wt.% was also removed.
As stated in the SER for Revision No. 13 of the CoC, the polyethylene equivalent mass for 8x8, 9x9, and 10x10 UO2 is unlimited in all cases for rods less than 5 wt.% 235U. For BWR 10x10 rods greater than 5 wt.% but less than 8 wt.% 235U, there is a polyethylene mass limit of 32.1 kg when these rods are stored within the stainless-steel pipe. In all other configurations, the polyethylene mass is unlimited (i.e., there is a mass limit in the stainless-steel pipe when the enrichment X is 5 wt.% X 8 wt.% 235U).
CONCLUSION
Based on the statements and representations in the application, and the conditions listed in the CoC, the staff concludes that the package meets the requirements of Title 10 of the Code of Federal Regulations (10 CFR) Part 71.
Issued with CoC No. 9309, Revision No. 14.
