RECAP 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 Previous design Current design Safety proof updates since 1st pre-application meeting in June 2020 Structural analysis (takes current design into account)
Criticality analysis: benchmark evaluation with TSUNAMI 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021 Page 3
DESIGN OF DN30-X: NEW CONCEPT Concept for DN30 Concept for DN30-X 30B Cylinder 30B-X Cylinder DN30 PSP 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021 Page 4
DESIGN OF DN30-X: PACKAGE 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 Enrichment UF6 Capacity Licensing Cylinder in % lb kg Status 5B 100 54.9 24.9 No PSP 8A 12.5 255 115 No PSP 30B 5 5020 2277 DN30 PSP 30B-10 10 3527 1600 DN30 PSP 30B-20 20 2756 1250 DN30 PSP 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021 Page 5
DESIGN OF DN30-X: DN30 PSP 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 0045-PRT-2021-001-REV0-NRC-PREAPPLICATION-17-02-2021 Page 6
