Context

New industry demands for higher enrichments (SMR and HALEU projects)

Cylinders defined in ANSI N14.1 (5B, 8A, 30B)

Solution: DN30-X package

DN30 PSP

30B-X cylinder with CCS

Safety proof updates since 1st pre-application meeting in June 2020

Structural analysis (takes current design into account)

Criticality analysis: benchmark evaluation with TSUNAMI Page 3 RECAP 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021 Previous design Current design

Type AF package with the DN30 PSP and the 30B-X cylinder

DN30 PSP unchanged from the licensed DN30 package

Modified 30B-X cylinder with criticality control features Fully compliant with 10 CFR 71 and SSR-6; no changes or exceptions required

Different designs for optimized UF6 capacity Page 5 DESIGN OF DN30-X: PACKAGE Cylinder Enrichment in %

The DN30 PSP as part of the DN30 package

Designed to accommodate a standard 30B cylinder

Provides mechanical and thermal protection for the cylinder during NCT and HAC Passed the NCT and HAC drop tests with fully loaded cylinders Package passed the HAC fire test even with an empty cylinder

DN30 package is licensed in the US and France with max. 5 % enrichment Validations in all relevant countries available More than 250 DN30 PSPs in operation today, 80 more will become available this year The DN30 PSP as part of the DN30-X package

Unchanged design, but accommodates the modified 30B-X cylinder Page 6 DESIGN OF DN30-X: DN30 PSP 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021
