UNIVERSITY OF MARYLAND, REQUEST FOR ADDITIONAL INFORMATION REGARDING THE LICENSE RENEWAL FOR THE MARYLAND UNIVERSITY TRAINING REACTOR ("MUTR") (TAC NO. ME1592), Docket No. 50-166, License No. R-70 The University of Maryland (UMD) hereby submits its responses to the NRC's Requests for Additional Information issued by letter dated September 8, 2011.

The September 8, 2011 RAIs concerned dose calculations submitted as Enclosure 2 to the University of Maryland letter of July 5, 2011. The dose calculations in Enclosure 2 addressed the occupational dose to workers, the dose to a member of the public in the Nuclear and Chemical Engineering Building next to the Maryland University Training Reactor (MUTR),

and the dose at the nearest residence during a maximum hypothetical accident (MHA) and normal operations. In the calculations, UMD considered two operational modes of the ventilation system, namely ventilation "on" and ventilation "off. The purpose of these calculations was to demonstrate that the occupational doses to workers and doses to the members of the public would not exceed the limits of Title 10 of the Code of Federal Regulations (10 CFR) Part 20, "Standards for Protection Against Radiation." Request for Additional Information 1 raised four questions regarding the analysis of the consequences of the Maximum Hypothetical Accident.

As requested in Item 2 of your email of September 20, 2011, I am submitting our most up to date tentative schedule for the re-installation of the fission chamber and subsequent reactor operations to re-evaluate Ar-41 measurements and dose calculations initially in our July 5, 2011 submission in response to Request for Additional Information 2 issued by letter dated September 8, 2011. As you are aware, we have had a number of setbacks which impacted our original schedule which we provided to you in the 5 July letter.

Hopefully, all of the issues (mainly circuitry) have been resolved. At the present time, the final welding of the aluminum can that houses the fission chamber will be completed at the beginning of next week (the week of October 17, 2011). After the weld is leak tested, we will be able to begin installation back into the core by late next week. Assuming all proceeds well, installation and initial testing should be completed by 14 October. Per our original schedule, we anticipate three weeks of reactor operation (various power levels and run times), sample collection and analyses, followed by two weeks for final dose calculations and assessment and preparation of the final report which we anticipate can be submitted by November 18, 2011.

Calculations of Doses to Occupational Personnel and Members of the Public due to MHA and Normal Operations at the Maryland University Training Reactor Note:

Internal and external components of doses are denoted for each category as applies.

Dose conversion factors are taken from the RADAR website and are consistent with ICRP and IAEA values http://www.doseinfo-radar.com/RADAR-INT-Occ.html In the August 10, 2011 teleconference with the NRC and consultant it was determined that the most likely exposed member of the public would be an individual residing at the fence line to the reactor facility and not an individual outside the door since there should be no force pushing anything, like a cloud out through the cracks in such cases as a leak with the ventilation off.

Normal Operations doses will be determined based on Ar-41 concentrations measured following the restart and operation of the reactor.
