INCOMING 0 OUTGOING The phone call between NRC staff and Croft Associates Limited to discuss the content specification in amending the Model No.
3977 A Certificate of Compliance began at approximately 10 A.M. eastern standard time. Croft provided in the original app lication a table ofnuclides generated by the proton irradiation ofa Thorium-232 disc but did not identify the nuclides as proprietary information. However, in their response to a request for additional information, Croft provided a more extensive list of nuclides and requested the list of nuclides be withheld as proprietary information. NRC staff explained that, because Croft had chosen to specify the contents by the nuclides generated by irradiating the thorium disc, this would create problems in modifying the ce1iificate of compliance and suggested that the contents be specified using parameters associated with the proton irradiation of the thorium disc (e.
g., cooling time). It was explained to NRC staff that this might require additional amendments if the irradiation parameters were Continue on Page 2 ACTION REQUIRED (IF ANY)

SUMMARY

U.S. NUCLEAR REGULATORY COMMISSION CONVERSATION RECORD (continued) were changed. There was some discussion of modify ing the shielding analysis approach. However, because the current analysis had very little margin to the regulatory dose rates, changing the shielding analysis was not considered viable. NRC staff then suggested specify ing the content using the source term (i.e., using the number of particles emitted from the irradiated thorium disc as well as the energy associated with the particles emitted) since this method had previously been used to approve packages. This was acceptable to Croft. The call concluded at approximately 11 :00 A.M. eastern standard time.
