During this maintenance, the pulse rod position was lowered 1.125" to make it more centrally-located in the reactor core.VI. Summary of 10 CFR 50.59 changes There were two 50.59 changes that were evaluated, approved, and implemented in CY 2009. One was to change the way printing is done from the CSC computer.
The change involved adding a parallel-to-USB conversion process to allow a USB printer to be used. The second 50.59 change involved security system upgrades that were performed as part of a NNSA-sponsored program to enhance facility security.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.

- Note: Minor contamination event in October resulted in a release of 1.43 pCi of Co-60 through the normal air exhaust on the roof, resulting in an annual average airborne release of 9.61x10-1 4 pCi/ml. This annual average airborne effluent release is 0.19% of the 10 CFR Appendix B limit of 5x1 0-11 pCi/ml for Co-60.B. Two solid low-level waste shipments, totaling 15 cu.ft., part of which was reactor generated, were made this calendar year.VIII. Radiation Monitoring 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 10-8 jtCi/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.5
- 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. Other than the contamination event of 10/22/09, the highest removable contamination found was equal to 94 pCi/1 00 cm 2 beta, near the back door of the storage building (Bldg 10). No areas were greater than 15 pCi/1 00 cm 2 alpha contamination.
The contamination event of 10/22/09 is detailed in another report, but it resulted in a maximum beta activity of 2812 pCi/100 cm 2 in the reactor room near the reactor tank. This contamination was quickly identified and cleaned.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.

Environmental TLDs were supplied and analyzed by Global Dosimetry Solutions.
- The exhaust stack dosimeter was knocked off of the exhaust duct by a severe hail storm in July and therefore this reading is lower than it should have been.X. Environmental Monitoring There was a minor contamination event in October that resulted in a release of 1.43 pCi of Co-60 through the normal air exhaust on the roof. Routine biennial environmental soil and water samples will be taken in the summer of 2010.7
