REQUEST FOR ADDITIONAL INFORMATION MISSOURI UNIVERSITY OF SCIENCE AND TECHNOLOGY DOCKET NO. 50 -123

1. Provide the purpose, frequency, and duration of operating the reactor at power levels ranging from 200 kW to 300 kW. Discuss reactor design, safety function, and procedures that prevent the reactor from exceeding the fuel cladding temperature and an uncontrolled reactor transient.

2. Section 14.3.2.2. Section 7.2.2.4 of the MSTR SAR specifies two channels: High Voltage (HV) Safety Channel No.1 and HV Safety Channel No. 2 for scram functions. However, these channels are missing in TS 14.3.2.2. Provide justification why these channels are not included in TS 14.3.2.2.

3. Section 14.3.4. The specification in this section states: The reactor shall not be operated unless the reactor truck door is closed and the ventilation intake and exhaust duct louvers are operable or secured in a closed position. Discuss whether any work is allowed involving core fuel loading, or installed control rods when the confinement is not operable.

4. Section 14.3.6.1. The specification in this section states: The reactor shall not be operated unless the Continuous Air Monitor (CAM) is operable and the Radiation Area Monitors (RAMs) located at the reactor bridge, at the demineralizer, and in the basement experimental area are operable. Discuss the CAM design (associated alarms, set points, and warning circuitry), surveillance, and reactor procedure that ensure the CAM can perform its intended function including preventing an undetected release of airborne radioactivity to the health and safety of the public, MSTR personnel, or the environment.

5. Section 6.2.1 of the current TS specifies that the Committee shall be composed of at least five members. However, Section 14.6.2.1 of the proposed TS specifies that the Committee shall be composed of at least three members. Provide justification why the Committee specified in the proposed TS is composed of at least three members. Also provide discussion on how the quorum requirement in TS 14.6.2.2 (1) will be met if two of the minimum three members have reactor operation responsibilities.

6. Section 9.2, Handling and Storage of Reactor Fuel. Provide dimensions of the wall that separates the main pool and the fuel storage pit.

7. Under 10 CFR 50.33(d), Contents of applications; general information, certain information is required by the applicant, Missouri University of Science and Technology Reactor (MSTR),

as applicable. To comply with this regulation, please update the application to include a statement of the organizational form of MSTR (e.g., corporation, etc.), the state where it is incorporated or organized and the principal location where MSTR does business, and the names, addresses and citizenship of directors and principal officers. Also, please state whether the MSTR is owned, controlled, or dominated by an alien, foreign corporation, or foreign government, and if so, give details.

Enclosure

8. Under 10 CFR 50.33(f)(2), The applicant shall submit estimates for total annual operating costs for each of the first five years of operation of the facility. Provide the projected operating costs of the MSTR for each of the years FY2009 to FY2013 (the first five year period after the projected license renewal) as well as MSTRs primary source(s) of funding that covers the operating costs for the above fiscal years.

9. The supplement to the application indicates that that cost to decommission the MSTR ranges from $ 1.9 million to $ 5.8 million depending on the disposal option selected. The staff needs the following additional information to complete its review:

a. Selected disposal option and the basis for the disposal option selected.

b. MSTRs plans to adjust the level of funds in the escrow account periodically over the life of the MSTR to meet changes in the decommissioning cost estimate.

c. Copy of the financial mechanism that reflects the updated decommissioning costs.
