Summary of 10 CFR 50.59 changes There were two 50.59 changes that were evaluated, approved, and implemented in CY 2010. One was to add a test circuit for testing the pool water temperature alarm.The change involved hard-wiring a test circuit to the existing water temperature monitoring circuitry.
The second 50.59 change involved an upgrade to the console.Currently one LCD flat-panel monitor has replaced one old CRT monitor; a second LCD flat-panel monitor in combination with a DELL computer was added to replace/emulate the old Tektronics monitor. Further upgrades will be performed during CY2011.VII. Radioactivity Releases A. Listed below are the total amounts of radioactive gaseous effluent released to the environment beyond the effective control of the reactor facility.Table 1.

0.051%* 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 Test America Laboratories.
B. A solid low-level waste shipment of 7.5 cu.ft., part of which was reactor generated, was shipped this calendar year.VIII. Radiation Monitorina 3
Our program to monitor and control radiation exposures included the four major elements below during the operating year.1. Fifteen 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 mR/hr to 50 mR/hr. High level alarms are very infrequent and due to sample movements.
- 2. One Continuous Air Monitor (CAM) samples the air in the reactor bay. An equilibrium concentration of about 1 x 108 ýtCi/ml present for two minutes will result in an increase of about 400 cpm above background.
The alarm setpoints are a low-level alarm set at 3000 cpm and the high level alarm 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 values in 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 instruments are calibrated with a 3-Curie (initial activity)
Cs-1 37 source traceable to NBS, and wipes are counted on a Gamma Products G5000 low level counting system. The highest removable contamination found was equal to 523 pCi/1 00 cm beta, on top of the north lead storage cave. This area was successfully decontaminated below MDA.The next highest removable contamination found was equal to 176.5 pCi/100 cm 2 beta, on top of the north lead storage cave as well. No areas were greater than 17.2 pCi/1 00 cm 2 alpha contamination.
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 four outdoor environmental stations.
Reactor facility visitors are issued self-reading dosimeters.
Reactor staff personnel are issued beta, gamma, albedo neutron badges.Table 2.

X. Environmental Monitorina 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).
