THE OHIO STATE UNIVERSITY RESEARCH REACTOR ANNUAL REPORT FOR FY 95/96 SEPTEMBER 20,1996

1 4

, Introduction As stated in The Ohio State University Research Reactor Technical Specifications, Section 6.6.1 Operating Reports, an annual report shall be made to the NRC by September 30 of each year. This report is to include the following seven sections.

1. A narrative summary of operating experience (including experiments performed) and of changes in facility design, performance characteristics, and operating procedures related to reactor safety occurring during the reporting period.

2. A tabulation showing the energy generated by the reactor (in Kilowatt hours) and the number of hours the reactor was in use.

3. The results of safety-related maintenance and inspection. The reasons for corrective maintenance of safety-related items shall be included.

4. A table of unscheduled shutdowns and inadvertent scrams, including their reasons and the corrective actions taken.

5. A summary of changes to the facility or procedures, which affect reactor safety, and performance of tests or experiments carried out under the conditions of sections 50.59 of 10CRF50.

6. A summary of the nature and amount of radioactive gaseous, liquids, and solid effluents released or discharged to the environs beyond the effective con:rol of the licensee as measured or calculated at or prior to the point of such release or discharge.

7. A summary of radiation exposures received by facility personnel and visitors, including the dates and times of significant exposures.

These seven sections are discussed below. These are all for the period July 1,1995 through June 30,1996, except as noted for exposure records, l . A. Experiments Performed The staff of The OSU Research Reactor are generally involved in four types of experiments at the Nuclear Reactor Laboratory, included are introductions to nuclear research, neutron activation analysis, material irradiations, and classes that measure various reactor parameters. Typically when we introduce students, faculty or other experimenters to nuclear research, we do the following:

a. Discuss nuclear reactions and radiological safety.

b. Operate the reactor at 10kW-100kW

c. llave the individuals observe control room operations.

d. Complete a tour and demonstrate irradiation techniques.

Neutron activation analysis experiments are routinely completed for students ranging from high school to graduate school. The facilities normally utilized are the " rabbit" (pneumatic tube) and the "CIF" (Central Irradiation Facility). The majority of the NAA work is geological samples. Irradiations are typically no longer than six hours.

Material irradiations, other than for NAA, are in four basic areas: isotope production, detector, electronic component and fiber optic testing; boron neutron capture therapy (BNCT); and irradiation of biological samples. Isotope production is extremely limited.

1

. Detector and electronic component testing is done routinely. This testing is usually completed in the thermal column, or one of the beam ports, while fission chamber testing is in the Central Irradiation Facility. The reactor thermal column is also utilized for other BNCT studies. Typically it is the location for cell samples to determine their boron -

content. ,

Various nuclear engineering or physics classes throughout Ohio utilize the reactor for the  ;

following basic experiments.

a. Approach to critical (using banked control rods rather than fuel loading).  !

b. Control rod calibration by rod drop, positive period, and subcritical l multiplication. i

c. Measurement of the Reactor Transfer function.

d. Void coefficient measurements.

e. Radiological surveys.

The reactor utilization for July 1,1995 through June 30,1996 is summarized in the l following reports.  !

~ 6.' Radioactive Effluents A. Gaseous Effluent -The only effluent we measure is the release of Ar-41. For the period July 1 - Dec. 31,1995, Ar-41 releases measured 1.74% of the Annual Average Concentration Limit. From Jan.1 - June 30,1996, releases measured 8.6% of the annual average concentration limit.

. s B. Liquid Releases-Ilot sink releases are recorded and reported through the OSU Office of Radiation Safety. Releases from the reactor pool to the sanitary sewer totaled approximately two microcuries. i C. No releases of solid radioactive material were made to the uncontrolled environment.

7. Radiation Exposures Since the firm that maintains records for The Ohio State University keeps a year to date record, it is easier to report this by the nearest completed calendar year. Therefore film .

~

badge exposures in this report are for the period January 1,1995 to December 31,1995.

Four individuals were monitored as radiation workers for the entire year or a major part of it. These are tabulated below. They are consistent with the ALARA policy for The Ohio State University and represent a fraction of allowed limits. All doses are in millirem.
