United States Nuclear Regulatory Commission One White Flint North MS 12G13 11555 Rockville Pike Rockville, Maryland 20852-2738 ATTN: ALEXANDER ADAMS, JR August 4, 2004 Enclosed please find the University of Maryland's response to the request for additional information as it pertains to the Environmental Report for the Maryland University Training Reactor.
I declare under penalty of perjury that the foregoing is true and correct.
Executed on August 4, 2004
[Signature ohamad Al-eIkhly, Director University of Maryland Training Reactor License Number R-70, Docket number 50-166 AO
I ENVIRONMENTAL REPORT
- 72.Section V of the 1999-2000 Annual Operating Report states that continuous monitoring for the year was accomplished using fixed-mounted film badges throughout the interior of the reactor building. Facility Technical Specification 3.6.4 specifies that the campus radiation safety organization maintain an environmental monitor at the site boundary as well. Explain how compliance is demonstrated, and if any abnormal radiation levels were ever detected.
Response
These environmental monitors are mounted on the east and west exterior walls of the building and have been evaluated for more than a decade. A synopsis of the readings is shown in the following table for the period of January 15, 1999 to present. The results are gross readings and are not background adjusted.

Considering the naturally occurring background, these results are statistically indistinguishable from other areas that are not in the vicinity of a nuclear facility. All results of the area monitors are delivered to the University of Maryland Radiation Safety Office where they are reviewed and approved by the Radiation Safety Officer.
Any elevated readings will be brought to the attention of the Reactor Director and if warranted, to the Radiation and Reactor Safety Committees.
- 73. Discuss actual releases of airborne, liquid and solid waste from the facility for the past 10 years and if these trends are expected to continue in the future.
Response
The manufacture and release of liquid and solid waste is typically limited to one cubic foot of low level resin from the ion exchange column and one sock filter per year. The levels are typically not more than three times the background levels of the area. The sock filter is approximately 500 grams and consists of a fibrous synthetic tube that is closed on one end. This is the coarse filter for the primary coolant system as described in the FSAR.
There has been no liquid waste released other than the overflow from the vessel overflow. This waste was surveyed by the Radiation Safety Office and approved for discharge into the environment. The sump is emptied approximately every three to five years with a total volume of approximately 50 gallons.
This pattern of minimal release is expected to continue as the MUTR is predominantly a training facility with occasional NAA that is typically performed with extremely small quantities of samples which are held for decay and not disposed of as radioactive waste.
