ATTN: Mr. H. E. Eskridge, Supervisor Nuclear Licensing, Safety and Accountability Route 21-A Hematite, Missouri 63047 Gentlemen:
We have reviewed your application of August 22, 1979, for an amendment to Special Nuclear Material License No. SNM-33 to authorize operation of a new waste incinerator in area 240-3 of the Hematite Plant. Our review has revealed a need for additional information, identified in the enclosure, concerning the safety of the operation. The requested information was discussed in a telephone conversation with Mr. H. E. Eskridge on September 13, 1979, and he plans to provide a written. response within two weeks. Our review of the application will be continued following receipt of the requested additional information.
Sincerely, V

Questions on Application Dated August 22, 1979, Combustion Engineering, Inc.,
Docket 70-36
- 1. 'The mass limit for the incinerator allows for possible double batching of a homogeneous system of moderated oxide, but does not explain how the uncertainty of the charge measurements will be considered.
Please explain how the charge uncertainty is allowed for in the operating controls, including the uncertainty in the uranium enrichment.
2.
Please justify the annual inspection frequency of the auxiliary equipment in terms of possible hazardous fissile material accumulations in the equipment during that interval.
3.
Please describe the main radiation safety controls that will be used to ensure the safety of the incinerator operation, e.g.,
differential pressure instruments or alarms.
4.
Please confirm that the gas firing system will be provided with the standard fire safety controls (e.g., automatic cut-off in the event the flame goes out).
