- 48824-I226 DnNON Of ENGINEERING RESEARCII February 28, 1986 Director of Inspection and Enforcement U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Docket No. 50-294 Pursuant to 10CFR50.59 the following is submitted as an annual report of activities and events during the period of January 1, 1935 to December 31, 1985.
- 1. The following experiments were performed during the period:
- a. 29_ central thimble irr-adiations jg
- b. 355 rotary specimen rack irradiations
- c. 4 pulse operations
- 2. There were no changes in facility design, performance characteristics, or operating procedures related to safety during the period.
- 3. The results of surveillance tests and inspections showed no deviations from previous reports so as to be noteworthy.
- 4. The total energy output during the period was 1.6385 Megawatt-days.
- 5. During the period there were 7 unscheduled scrass.
- a. 3 scrams due to the linear recorder
- b. 2 scrams due to the operator error of the linear recorder
- c. 2 scrama due to the period meter
- 6. There were no major maintenance operations performed.
l l 7. There were no changes in the facility or its procedure as relates to the l tests and/or experiments carried out at the facility, during the period. ,
i 8. There was no liquid radioactive waste discharged during the period.
l l 9. The total argon-41 release during the period was 25.4 mci or an average release of 2.19 x 10-9 uCi/cc or 5.5% MPC.
- 10. There was no release of radioactive particulate during the reporting period.
I
[
- 11. The average concentration of other significant radionuclides present in l
gaseous form and thus discharged from our facility is estimated to be less than 20% the applicable MPC therefore no report is made of addi-tional releases.
- 12. Radiation exposure to visitors of the laboratory during the period was as follows:

- a. Sexton High School tour-group 10 mrem this badge was removed of 12 from the lab and returned to us one month later via U.S. Mail. No exposure on the badges of the two tour guides for the same period,
- b. Chemical Engineering Class of 3 20 mrem Emergency badges stored in the basement of the Engineering Bldg. and not issued during the period showed the same exposure.
- c. Chemical Engineering Class of 3 20 mrem same as above Facility Personnel Exposure Record
- a. Mark Mitchell 10 mrem Emergency badges stored in the basement of the Engineering Bldg. and not issued during the period showed 20,20, and 10 mrem.
There were no exposures in excess of the 10CFR Part 20 limits
- 13. Two incidents of removable contamination were found around the sample port on the bridge of the reactor pool during routine radiation surveys (10/4 and 12/4). In both instances the reactor had been operational the day before and samples were temoved from the core. Radiation levels were 3 to 4 times background and cleaning the area with Radiac Wash reduced the levels to background.
