This report is to include the following seven information items:1. A narrative summary of operating experience (including experiments performed) and ofchanges in facility design, performance characteristics, and operating procedures relatedto reactor safety occurring during the reporting period2. A tabulation showing the energy generated by the reactor (in kilowatt hours) and thenumber of hours the reactor was in use3. The results of safety related maintenance and inspections and the reasons for correctivemaintenance of safety-related items4. A table of unscheduled shutdowns and inadvertent scrams, including their reasons andthe corrective actions taken5. A summary of the safety analyses performed in connection with changes to the facility orprocedures, which affect reactor safety, and performance of tests or experiments carriedout under the conditions of 10 CFR 50.596. A summary of the nature and amount of radioactive gaseous, liquids, and solid effluentsreleased or discharged to the environs beyond the effective control of the licensee asmeasured or calculated at or prior to the point of such release or discharge7. A summary of radiation exposures received by facility personnel and visitors, includingthe dates and times of significant exposuresThese seven information items are discussed below for the period July 1, 2013 through June30, 2014, except as noted for exposure records.1. Summary of Operating Experience and ChangesI.A. Experiments PerformedThe OSURR engages in a wide range of research endeavors, including neutron activationanalysis (NAA), radiation-damage studies, neutron and radiation sensitive detectordevelopment, isotope production, and biomedical experiments. Much of the NAA workperformed at the OSURR is for geological and material science samples, but NAA is used forother purposes, such as industrial and biological. Most radiation-damage studies performed atthe OSURR are for electronic and fiber-optic components, but studies have been performed forother materials. The OSURR has been involved in the development of a number of potentialtypes of neutron and radiation detectors, including fiber-optic based systems, and it regularlytests fission chambers for use in commercial power reactors by characterizing their response toknown neutron flux. Isotope production has typically been performed for medical research, butsources have been created for other uses, including testing of radiation-sensitive detectors.Biological sample irradiations performed at the OSURR have been for boron neutron capturetherapy (BNCT) studies. In addition, other experiments are performed at the OSURR, such asreactivity worth measurements, spectrum characterizations using flux-wire activation andanalysis, and physics experiments such as neutron irradiation of fullerenes.The OSURR also provides a variety of instructional services ranging from general tours toindividual and group laboratory sessions and research projects structured to student and facultyOSURR Annual ReportPage 2 of 9Sep 2014 interests. Nuclear engineering and physics classes throughout Ohio have utilized the OSURRfor 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 multiplicationc. measurement of the reactor transfer function by noise analysisd. temperature coefficient measurementse. radiological surveysWhen the OSURR is used to introduce students, faculty or other experimenters to nuclearresearch, the following are typically done:a. discuss nuclear reactions and radiological safetyb. operate the reactor at 10kW-100kWc. have the individuals observe control room operationsd. complete a tour and demonstrate irradiation techniquesNeutron activation analysis experiments are performed for students ranging from high school tograduate school.The reactor utilization for July 1, 2013 through June 30, 2014 is summarized in the followingreports. Please note that the utilization hours listed below only reflect actual reactor operatingtime. The list does not include hours spent on tasks supporting this reactor utilization.OSURR Annual ReportPage 3 of 9Sep 2014 The Ohio State University Nuclear Reactor Lab Reactor Utilization Report:July 1 -December 31, 2013User (Affiliation) Description HoursCharles (AFIT) Radiation effects on semiconductors 2.0Greb (AFIT) Cu-64 production 0.6Recker (AFIT) Cu doping of ZnO 28.6Singleton (AFIT) Radiation effects on optical fibers 14.3Schaefer (Air Force) Carbon fullerites 1.8Lepper (NDSU) NAA of geological samples 1.4GE Reuter-Stokes QA testing fission chambers 24.9OSU NE4506 Undergraduate lab classes 10.1 2Cao (OSU NE) Beam experiments (NDP, imaging, etc.) 16.8 2Wilson (OSU NE) Gamma measurements in 7" tube 9.5Prime Photonics Radiation effects on TGG crystal 2.5Scintiprox NAA of chemical tablets 1.1Shepherd Color NAA of plastics 1.4 2Glover (UC) NAA of fly ash, irradiation of silica disks 6.8NRL Staff Maintenance activities, facility characterization 9.9Various.

Procedure changesThe following is a list of procedure changes made under 1 0-CFR-50.59 from July 1, 2013 toJune 30, 2014 in accordance with Administrative Procedure AP-06, Format for Writing,Revising, and Approving Procedures.OSURR Annual ReportPage 6 of 9Sep 2014 Procedure Procedure RevisionNumber Title DateRS-08 NRL Smear Survey 09/19/13RS-09 Area Radiation Surveys 09/17/136. Radioactive Effluents6.A. Gaseous EffluentThe only gaseous effluent measured is the release of Ar-41. For the period July 1 -Dec. 31,2013, Ar-41 releases measured 1.10% of the annual average concentration limit. From Jan. 1 -June 30, 2014, releases measured 1.49% of the annual average concentration limit. Inaccordance with the requirements of 1 OCFR20. 1101 (d), the COMPLY code was run using thetotal Ar-41 release for the period July 1, 2013 -June 30, 2014 of 208.3 mCi. Using level 2 in thecode, the effective dose equivalent rate at the facility fence was computed to be 0.1 mrem/yr.This is well below the 10 mrem/yr constraint specified in the regulation.6.B. Liquid ReleasesHot sink releases are recorded and reported through the OSU Office of Radiation Safety. Noreleases were made to the sanitary sewer system during the period July 1, 2013 to June 30,2014.6.C. Solid ReleasesNo releases of solid radioactive material were made to the uncontrolled environment.7. Radiation ExposuresSince 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, 2013 toDecember 31, 2013. Thirteen individuals were monitored as radiation workers during thisperiod, and the measured dose equivalent values are tabulated below in mrem.Individual Dose Equivalent (mrem _DDE LDE SDE, WB SDE, MEVisitors 0 0 0 N/AStaff member #1 19 38 89 180Staff member #2 0 0 0 0Staff member #3 146 153 157 549Staff member #4 72 73 73 224Staff member #5 119 122 122 409Staff member #6 24 27 27 80Staff member #7 6 6 6Student #1 0 0 0 30Student #2 9 9 9 83Student #3 8 8 8 125Student #4 6 7 7 76Student #5 13 16 16 103Student #6 26 28 28 97OSURR Annual ReportPage 7 of 9Sep 2014 COMPLY: V1.6.7/ 1/2014 3:1340 CFR Part 61National Emission Standardsfor Hazardous Air PollutantsREPORT ON COMPLIANCE WITHTHE CLEAN AIR ACT LIMITS FOR RADIONUCLIDE EMISSIONSFROM THE COMPLY CODE -V1.6.Prepared by:Ohio State UniversityNuclear Reactor Lab1298 Kinnear Road, Columbus, OH 43212Andrew Kauffman614-688-8220Prepared for:U.S. Environmental Protection AgencyOffice of Radiation and Indoor AirWashington, DC 20460OSURR Annual ReportPage 8 of 9Sep 2014 COMPLY: V1.6.7/ 1/2014 3:13OSU NRLSCREENING LEVEL 2DATA ENTERED:NuclideAR-41Release Rate(curies/YEAR)2.083E-01Release height 10 meters.Building height 11meters.The source and receptor are not on the same building.Distance from the source to the receptor is 15 meters.Building width 25 meters.Default mean wind speed used (2.0 m/sec).NOTES:Input parameters outside the "normal" range:None.RESULTS:Effective dose equivalent: 0.1 mrem/yr.*** Comply at level 2.This facility is in COMPLIANCE.It may or may not be EXEMPT from reporting to the EPA.You may contact your regional EPA office for more information.END OF COMPLIANCE REPORT *OSURR Annual ReportPage 9 of 9Sep 2014
