CONVERSATION RECORD (continued)

SUMMARY

(Continued from page 1)

Observation (OBS} NRC staff clarified that SMUD should provide the comparison between the Rancho Seco sample collection protocol with that ofEPRI. SMUD needs to clarify the uncertainties of the data used in the renewal application. 1N Americas will take the action to address.

OBS NRC staff clarified that an editorial change is needed to the application in Section 3.4.4.4 that would describe the licensing basis in the context of the contents of the DSC.

OBS The NRC staff clarified that they are looking for a basis and/or reference for the depth of the beat affected zone quoted in Section 3.4.4.5.

OBS The NRC staff noted that Application Section 3.5.4.5 does not address whether lubricant deterioration affects retrievability.

OBS The NRC staff notes that, for consistency, Application Section B.3 DSC External Surfaces Aging Management Program may need to include a tollgate discussion to assess effectiveness of corrective actions and update the AMP as necessaiy.

OBS The NRC clarified that the potential use of the MP-187 transfer cask to serve as a pressure boundary for a leaking dry shielded canister (DSC) as described in the renewal application needs to be considered in the MP-187 aging management program.

SMUD informed the NRC staff that, because of the effort required to address this observation, they may defer and address as a request for additional information during the application review period.
