THE OHIO STATE UNIVERSITY RESEARCH REACTOR ANNUAL REPORT FOR FY 2014/2015 SEPTEMBER 2015 OSURR Annual Report Pg 1 off9Sp21 Page 9 Sep 2015

Introduction As stated in The Ohio State University Research Reactor (OSURR) 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 information items:

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 inspections and the reasons for corrective maintenance of safety-related items

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

5. A summary of the safety analyses performed in connection with changes to the facility or procedures, which affect reactor safety, and performance of tests or experiments carried out under the conditions of 10 CER 50.59

6. A summary of the nature and amount of radioactive gaseous, liquids, and solid effluents released or discharged to the environs beyond the effective control 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 information items are discussed below for the period July 1, 2014 through June 30, 2015, except as noted for exposure records.

1. Summary of Operating Experience and Changes 1 ,A, Experiments Performed The OSURR engages in a wide range of research endeavors, including neutron activation analysis (NAA), radiation-damage studies, neutron and radiation sensitive detector development, isotope production, and biomedical experiments. Much of the NMA work performed at the OSURR is for geological and material science samples, but NMA is used for other purposes, such as industrial and biological. Most radiation-damage studies performed at the OSURR are for electronic and fiber-optic components, but studies have been performed for other materials. The OSURR has been involved in the development of a number of potential types of neutron and radiation detectors, including fiber-optic based systems, and it regularly Stests fission chambers for use in commercial power reactors by characterizing their response to known neutron flux. Isotope production has typically been performed for medical research, but sources have been created for other uses, including testing of radiation-sensitive detectors.

Biological sample irradiations performed at the OSURR have been for boron neutron capture therapy (BNCT) studies. In addition, other experiments are performed at the OSURR, such as reactivity worth measurements, spectrum characterizations using flux-wire activation and analysis, and physics experiments such as neutron irradiation of fullerenes.

The OSURR also provides a variety of instructional services ranging from general tours to individual and group laboratory sessions and research projects structured to student and faculty interests. Nuclear engineering and physics classes throughout Ohio have utilized the OSURR 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 multiplication

c. measurement of the reactor transfer function by noise analysis

d. temperature coefficient measurements

e. radiological surveys When the OSURR is used to introduce students, faculty or other experimenters to nuclear research, the following are typically done:

a. discuss nuclear reactions and radiological safety

b. operate the reactor atA10kW-1 00kW

c. have the individuals observe control room operations

d. complete a tour and demonstrate irradiation techniques Neutron activation analysis experiments are performed for students ranging from high school to graduate school.

The reactor utilization for July 1, 2014 through June 30, 2015 is summarized in the following reports. Please note that the utilization hours listed below only reflect actual reactor operating time. The list does not include hours spent on tasks supporting this reactor utilization.

6. Radioactive Effluents 6.A. Gaseous Effluent The only gaseous effluent measured is the release of Ar-41. For the period July 1 - Dec. 31, 2014, Ar-41 releases measured 0.46% of the annual average concentration limit. From Jan. 1 -

June 30, 2015, releases measured 1.17% of the annual average concentration limit. In accordance with the requirements of I0CFR20.1 101 (d), the COMPLY code was run using the total Ar-41 release for the period July 1, 2014 - June 30, 2015 of 130.0 mCi. Using level 2 in the code, the effective dose equivalent rate at the facility fence was computed to be 0.09 mrem/yr.

This is well below the 10 mrem/yr constraint specified in the regulation.

6.B. Liquid Releases Hot sink releases are recorded and reported through the OSU Office of Radiation Safety. No releases were made to the sanitary sewer system during the period July 1, 2014 to June 30, 2015.

6.C. Solid Releases 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 simpler to report radiation exposure records by the nearest completed calendar year.

Therefore, dosimetry badge exposures in this report are for the period January 1, 2014 to December 31, 2014. Twelve individuals were monitored as radiation workers during this period, and the measured dose equivalent values are tabulated below in mrtem.
