- Note: The tritium concentrations are estimates based on the amount of water lost by evaporation from the reactor multiplied by the concentration of tritium as HTO. Tritium sample analyses were performed by Hazen Research.
Note: The principal radioactive waste generated at the reactor facility is the demineralizer resin. Used resin with small quantities of rinse water is de-watered by
-evaporatdl~-placed-in-a.55-allon-drum-.-No waste-was.disposed-during the-calendar year'2004.
VIII. Radiation Monitorigg Our program to monitor and control radiation exposures included the four major elements below during the operating year.
- 1. Thirteen gamma-sensitive area monitors are located throughout the Nuclear Science Building. A remote readout panel is located in the reactor health physics office. High alarm set points range from 2 mRl/hr to 50 mR/hr. High level alarms are very infrequent and due to sample movements.
3
- 2. One Continuous Air Monitor (CAM) samples the air in the reactor bay. An equilibrium concentration of about 1 x 14 jiCi/ml present for two minutes will result in an increase of 400 cpm above background. There are two alarm setpoints. A low-level alarm is set at 3000 cpm and the high level alarm is set at 10000 cpm.
Reactor bay air is sampled during all reactor operations. The fixed particulate air filter is changed each week and counted on a HPGE gamma spectrometer counting system. The charcoal filter, fitted behind the air filter, is also changed and counted weekly. In all instances, sample data were less than airborne concentration value (10 CFR Part 20, Appendix B, Table 2) for all particulate radioisotopes produced by the reactor.
- 3. Contamination wipe surveys and radiation surveys with portable survey instruments are performed at least once a month. All portable beta-gamma
--instruments-are calibratedwith-aM3Curie-(initial activity)-Cs-137-source traceable to NBS, and wipes are counted on a Gamma Products G5000 low level counting system. Five areas were identified greater than 30 pCi/1 00 cm2 beta-gamma contamination. Two of the five areas of high removable contamination were found on the inside of the shipping cask @ 10,249 pCV1 00 cm2 beta-gamma and on the top of the table in the reactor room @ 1,007 pCV1 00 cm2 beta-gamma contamination. The other three areas of removable contamination were found on the reactor bay table and the small cave with 65 pCI100 cm2 beta-gamma, 31 pCiI 00 cm2 beta-gamma contamination, and on the reactor bay floor with 35 pCi/1 00 cm2 beta-gamma contamination. All other areas were less than 30 pCi/1 00 cm2 beta-gamma and 15 pCi/1 00 cm2 alpha.
The roof area over the reactor tank is roped off and posted as a radiation area (averaging 2.5 mR/hr) during 1 MW operations.
- 4. LiF TLD dosimeters were used at five outdoor environmental stations.
Reactor facility visitors are issued self-reading dosimeters. Reactor staff personnel are issued albedo neutron badges.

X. Environmental Monitorinq There have been no uncontrolled radioactivity releases from the reactor to the present date. Thus, the data on file from past years to the present are considered to be background information.
Environmental soil and water samples were taken and analyzed. No elevated readings or reactor-produced isotopes were identified (fallout Cs-1 37 was identified).
