Subject:
Answers to RSIs for the review of the DN30-X package
Dear Mr. Saverot,
This letter is in response to your request for supplemental information (RSI, reference Docket No. 71-9388, EPID No. L2020-NEW-0003) from September 22nd, 2021.
RSI-1:
We have revised Section 1.3 Specification of the Radioactive Contents in the SAR.
Instead of explicitly indicating the exceptions to ASTM C996, we have decided to thoroughly define the allowed contents in a self-contained way. ASTM C996 is only referred to for in-depth information or discussion.
We have revised Section 1.4.2.1.4 Additional provisions to ANSI N14.1 in the SAR.
This section lists the additional provisions (CCS and larger weld backing bar) the 30B-X cylinder has compared to a standard 30B cylinder, as well as explains their safety aspects.
RSI-2:
We have revised Sections 1.3.2.1 Permissible Mass of UF6 and 1.7.4.1 Filling and Emptying of the 30B-X Cylinder with UF6 in the SAR.
1.3.2.1: A note has been added to justify the maximum heel quantities for the 30B-10 and 30B-20 cylinders.
1.7.4.1: The potential impact of adding the internal CCS on filling, emptying and washing operations of the 30B-X cylinder is discussed.

RSI-3:
We have revised Section 1.3 Specification of the radioactive contents in the SAR.
We have indicated that HALEU shall be enriched from Commercial Natural UF6, and that neither Reprocessed nor Derived Enriched UF6 shall be used.
O-1:
We have revised Table 1-11 Material specification of interior CCS of the 30B-X cylinder in the SAR, as well as Points 6 to 8 in Section 6.1.2 Materials of the Specification and the Parts List of the 30B-10 and 30B-20 Cylinder.
The test temperature and the minimally required energy absorption (acceptance criteria) for the Charpy V-notch impact tests has been added, and we have changed the material for the CCR pipes.
