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
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

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
