Clarification: CASTOR geo69 Storage Application

Good morning,

The staff needs clarification on the meaning on the language highlighted in yellow in the paragraph below.

Figure 1.2-7: Schematic view (left) and cross section (right) of the transfer cask

In order to prevent clean demineralized water from leaking out of the cavity, an inflatable seal (Item 56 ) is foreseen to be placed in a T-shaped groove on the underneath of the bottom ring sealing against the bottom lid. A bore through the bottom ring creates a connection to the transfer cask cavity. Via a connection pipe (Item 50), it can be permanently flushed with demineralized water from below to prevent the canister cavity from inflowing contaminated pool water from the lid side during underwater pool loading.

It is not clear if the applicant means the following:

In order to prevent clean demineralized water from leaking out of the cavity, an inflatable seal (Item 56 ) is foreseen to be placed in a T-shaped groove on the located underneath of the bottom ring sealing against the bottom lid. A bore through the bottom ring creates a connection connects to the transfer cask cavity.

I will place your response in ADAMS under Docket No. 07201052, which is the Docket No. for the CASTOR geo69 storage application.

Please let me know if you have questions about this request.

Thanks in advance, Norma Garcia Santos Project Manager Storage and Transportation Licensing Branch Division of Fuel Management Office of Nuclear Material Safety and Safeguards
