REQUEST FOR ADDITIONAL INFORMATION OREGON STATE UNIVERSITY TRIGA REACTOR DOCKET NO. 50-243 The purpose of the following question is to determine possession limits under 10 CFR Part 70.
- 1.
For your proposed first stage license condition 2.b(5), your application states that you will receive, possess, but not use the new low-enriched uranium (LEU) fuel. However, your proposed license condition does not contain the constraint but not use. Please clarify.
Your proposed license condition also contains wording and to possess, but not separate, such special nuclear material as may be produced by the operation of the facility. Please explain how this wording is related to the possession of the new LEU fuel until the conversion order is issued? If this is a proposed general improvement to your license conditions, please submit it as part of your license renewal application.
The purpose of the following questions is to determine compliance with 10 CFR 50.64.
- 2.
Section 9, Auxiliary Systems. The end of this section states as fuel is received at the OSTR facility it will be stored in a physically secure location. Is this the location discussed in Section 9, or is there another storage location that will be employed? If there is another storage location, please discuss criticality of fuel stored in this location.
- 3.
Section 9, Auxiliary Systems. Why is K-eff with equal mixtures of fuel higher than it is with either high-enriched uranium or LEU fuel alone?
- 4.
Why does OSU need possession of the LEU fuel prior to issuance of the conversion order?
