REQUEST FOR ADDITIONAL INFORMATION UNIVERSITY OF MISSOURI RESEARCH REACTOR DOCKET NO. 50-186 The following questions are asked to determine compliance with the regulations in 10 CFR Part 20, Standards for Protection Against Radiation.

1. Please provide a detailed analysis with justification of assumptions of the radiological impact to persons in the reactor containment and members of the public from a failure of the fueled experiment irradiation container. While your proposed technical specification (TS) is based on certain iodine and strontium isotopes, please base your calculations on all isotopes that are likely to be released from the failed irradiation container.

2. How would failure of a fueled experiment be detected? What is the sensitivity of the radiation detection equipment? What actions, both automatic and operator initiated would be taken in response to an experiment failure?

3. Will the target processing be conducted under the reactor license? If so, describe the facilities that will be used. Describe how radioactive material will be controlled during target processing. Describe possible accident scenarios and the potential radiological impact of the scenarios.

The following question is asked to determine compliance with the conditions of your reactor license.

4. License condition 2.B.(2) allows you to possess, but not separate, such special nuclear material as may be produced by the operation of the facility.... Please describe the complete processing that the irradiated uranium targets will undergo. Explain how license condition 2.B.(2) is met during this process.
