Overview Executive Summary The data from this reporting year shows that the use of the Radiation Center and the Oregon State TRI GA reactor (OSTR) has continued to grow in many areas.

The Radiation Center supported 40 different courses this year, mostly in the School of Nuclear Science and Engineering.

About 40% of these courses involved the OSTR. The number ofOSTR hours used for academic courses and training was 9, while 3,621 hours0.00719 days <br />0.173 hours <br />0.00103 weeks <br />2.362905e-4 months <br /> were used for research projects. Eighty-four percent (84%) of the OSTR research hours were in support of off-campus research projects, reflecting the use of the OSTR nationally and internationally. Radiation Center users pub-1 ished or submitted 95 articles this year, and made 36 presen-tations on work that involved the OSTR or Radiation Center.

The number of samples irradiated in the reactor during this re-porting period was 2,861. Funded OSTR use hours comprised 84% of the research use.

Personnel at the Radiation Center conducted 114 tours of the facility, accommodating I, I 09 visitors. The visitors included elementary, middle school, high school, and college students; relatives and friends; faculty; current and prospective clients; national laboratory and industrial scientists and engineers; and state, federal and international officials. The Radiation Center is a significant positive attraction on campus because visitors leave with a good impression of the facility and of Oregon State University.

The Radiation Center projects database continues to provide a useful way of tracking the many different aspects of work at the facility. The number of projects supported this year was 107. Reactor related projects comprised 73% of all projects.

The total research dollars in some way supported by the Radia-tion Center, as reported by our researchers, was $8.8 million.

The actual total is likely higher. This year the Radiation Center provided service to 62 different organizations/institu-tions, 42% of which were from other states and 39% of which were from outside the U. S. and Canada. So while the Center's primary mission is local, it is also a facility with a national and international clientele.

The Radiation Center web site provides an easy way for potential users to evaluate the Center's facilities and capabili-ties as well as to apply for a project and check use charges. The address is: http://radiationcenter.oregonstate.edu.

0 Annual Report Introduction The current annual report of the Oregon State University Radiation Center and TRI GA Reactor follows the usual format by including information relating to the entire Radiation Center rather than just the reactor. However, the information is still presented in such a manner that data on the reactor may be examined separately, if desired. It should be noted that all annual data given in this report covers the period from July I, 2019 through June 30, 2020. Cumulative reactor operating data in this report relates only to the LEU fueled core. This covers the period beginning July I, 2008 to the present date. For a summary of data on the reactor's two other cores, the reader is referred to previous annual reports.

In addition to providing general information about the activi-ties of the Radiation Center, this report is designed to meet the reporting requirements of the U. S. Nuclear Regulatory Commission, the U. S. Department of Energy, and the Oregon Department of Energy. Because of this, the report is divided into several distinct parts so that the reader may easily find the sections of interest.

a

Overview of the Radiation Center The Radiation Center is a unique facility which serves the entire OSU campus, all otherinstitutions within the Oregon University System, and many other universities and orga-nizations throughout the nation and the world. The Center also regularly provides special services to state and federal agencies, particularly agencies dealing with law enforce-ment, energy, health, and environmental quality, and renders assistance to Oregon industry. In addition, the Radiation Center provides permanent office and laboratory space for the OSU Schoof of Nuclear Science and Engineering, the OSU Institute of Nuclear Science and Engineering, and for the OSU nuclear chemistry, radiation chemistry, geochemis-try and radiochemistry programs. There is no other university facility with the combined capabilities of the OSU Radiation Center in the western half of the United States.,

Located in the Radiation Center are many items of special-ized equipment and unique teaching and research facilities.

They include a TRI GA Mark II research nuclear reactor; a 60Co gamma irradiator; a large number of state-of-the art computer-based gamma radiation spectrometers and associat-ed germanium detectors; and a variety of instruments for ra-diation measurements and monitoring. Specialized facilities for radiation work include teaching and research laboratories with instrumentation and related equipment for performing neutron activation analysis and radiotracer studies; laborato-ries for plant experiments involving radioactivity; a facility for repair and calibration of radiation protection instrumenta-tion; and facilities for packaging radioactive materials for shipment to national,and international destinations.

Also housed in the Radiation Center is the Advanced Ther-mal Hydraulics Research Laboratory (ATHRL), which is used for state-of-the-art two-phase flow experiments.

The Multi-Application Light Water Reactor (MASLWR) is a nuclear power plant test facility that is instrumental in the development of next generation commercial nuclear reactors currently seeking NRC certification. The Test Facility is con-structed of all stainless steel components and is capable of operation at full system pressure (1500 psia), and full system temperature (600F).

All components are 1/3 scale height and 1/254.7 volume scale. The current testing program is examining methods for natural circulation startup, helical steam g~erator heat transfer performance, and a wide range of design basis, and beyond design basis, accident conditions. In addition, the MASLWR Test Facility is currently the focus of an interna-OVERVIEW tional collaborative standard problem exploring the operation and safety of advanced natural circulations reactor concepts.

Over 7 intern.¢onal organizations are involved in this stan-dard problem at OSU.

The Advanced Nuclear Systems Engineering Laboratory (ANSEL) is the home to two major thermal-hydraulic test facilities-the High Temperature Test Facility (HTIF) and the Hydro-mechanical Fuel Test Facility (HMFTF). The HTTF is a 1/4 scale model of the Modular High Temperature Gas Reactor. The vessel has a ceramic lined upper head and shroud capable of operation at 850oC (well mixed helium).

The design will allow for a maximum operating pressure of l.0MPa-and a maximum core ceramic temperature of 1600°C.

The nominal working fluid will be helium with a core power of approximately 600 kW (note that electrical heaters are used to simulate the core power). The test facility also includes a scaled reactor cavity cooling system, a circulator and a heat sink in order to complete the cycle. The HTIF can be used to simulate a wide range of accident scenarios in gas reac-tors to include the depressurized conduction cooldown and pressurized conduction cooldown events. The HMFTF is a testing facility which will be used to produce a database of hydro-mechanical information to supplement the qualifica-tion of the prototypic ultrahigh density U-Mo Low Enriched Uranium fuel which will be implemented into the U.S. High Performance Research Reactors upon their conversion to low enriched fuel. This data in turn will be used to verify current theoretical hydro-and thermo-mechanical codes being used during safety analyses. The maximum operational pressure of the HMFfF is 600 psig with a maximum operational tem-perature of 450°F.

The Radiation Center staff regularly provides direct sup-port and assistance to OSU teaching and research programs.

Areas of expertise commonly involved in such efforts include nuclear engineering, nuclear and radiation chemistry, neutron activation analysis, radiation effects on biological systems, ra-diation dosimetry, environmental radioactivity, production of short-lived radioisotopes, radiation shielding, nuclear instru-mentation, emergency response, transportation of radioactive materials, instrument calibration, radiation health physics, radioactive waste disposal, and other related areas.

In addition tq formal academic and research support, the Center's staff provides a wide variety of other services includ-ing public tours and instructional programs, and professional consultation associated with the feasibility,* design, safety, and execution of experiments using radiation and radioactive materials.

Facilities Research Reactor The Oregon State University TRJGA Reactor (OSTR) is a water-cooled, swimming pool type research reactor which uses uranium/zirconium hydride fuel elements in a circular grid array. The reactor core is surrounded by a ring of graphite which serves to reflect neutrons back into the core. The core is situated near the bottom of a 22-foot deep water-filled tank, and the tank is surrounded by a concrete bioshield which acts as a radiation shield and structural support. The reactor is li-censed by the U.S. Nuclear Regulatory Commission to operate at a maximum steady state power of 1.1 MW and can also be pulsed up to a peak power of about 2500 MW.

The OSTR has a number of different irradiation facilities including a pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, five sample holding (dummy) fuel elements for special in-core irradiations, an in-core irradiation tube, and a cadmium-lined in-core irradiation tube for experi-ments requiring a high energy neutron flux.

The pneumatic transfer facility enables samples to be inserted and removed from the core in four to five seconds.

Consequently this facility is normally used for neutron activa-tion analysis involving short-lived radionuclides. On the other hand, the rotating rack is used for much longer irradiation of samples (e.g., hours). The rack consists ofa circular array of 40 tubular positions, each of which can hold two sample tubes.

0 Annual Report Rotation of the rack ensures that each sample will receive an identical irradiation.

The reactor's thermal column consists of a large stack of graphite blocks which slows down neutrons from the reactor core in order to increase thermal neutron activation of samples.

Over 99% of the neutrons in the thermal column are thermal neutrons. Graphite blocks are removed from the thermal col-umn to enable samples to be positioned inside for irradiation.

The beam ports are tubular penetrations in the reactor's main concrete shield which enable neutron and gamma radiation to stream from the core when a beam port's shield plugs are removed. The neutron radiography facility utilized the tangen-tial beam port (beam port #3) to produce ASTM E545 category I radiography capability. The other beam ports are available for a variety of experiments.

If samples to be irradiated require a large neutron fluence, especially from higher energy neutrons, they may be inserted into a dummy fuel element. This device will then be placed into one of the core's inner grid positions which would nor-mally be occupied by a fuel element. Similarly samples can be placed in the in-core irradiation tube (ICIT) which can be inserted in the same core location.

The cadmlum-llned In-core lrradlatlou tube (CLICIT) enables samples to be irradiated in a high flux region near the center of the' core. The cadmium lining in the facility elimt-nates thermal neutrons and thus permits sample exposure to higher energy neutrons only. The cadmium-lined end of this air-filled aluminum irradiation tube is inserted into an inner grid position of the reactor core which would normally be oc-cupied by a fuel element. It is the same as the ICIT except for the presence.of the cadmium lining.

The two main uses of the OSTR are instruction and research.

Instruction Instructional use of the reactor is twofold. First, it is used sig-nificantly for classes in Nuclear Engineering, Radiation Health Physics, and Chemistry at both the graduate and undergradu-ate levels to demonstrate num*erous principles which have been presented in the classroom. Basic neutron behavior is the same in small reactors as it is in large power reactors, and many demonstrations and instructional experiments can be performed using the OSTR which cannot be carried out with a commercial power reactor. Shorter-term: demonstration experi-ments are also performed for many undergraduate students fu Physics, Chemistry, and Biology classes, as well, as for visitors from other universities and colleges, froµi high schools, and from public groups.

The _second instructional application of the OSTR involves educating ~ctor operators, operations managers, and health physicists. The OSTR is in a unique position-to provide such education since curricula must include hands-on experience at an operating reactor and in associated laboratories. The many types of educational programs that the Radiatipn Center pro-vides are more fully described in Part VI of this report.

During this reporting period the OSTR accommodated a number of different OSU academic classes and other academic programs. In addition, portions of classes from other Oregon universities were also supported by the OSTR.

Research The OSTR is a unique and valuable tool for a wide variety of research applications and serves as an excellent source of neutrons and/or gamma radiation. The.most commonly used experimental technique requiring reactor use is instrumental neutron activation analysis (INAA). This is a particularly sensitive method of elemental analysis which is descnbed in

'more detail in Part VI. :

The OSTR's irradiation facilities provide a wide range of neutron flux levels and neutron flux qualities which are suf-FACILITIES ficient to meet the needs of most researchers. This is true not only for INAA, but also for other experimental purposes such as the 39 ArflO Ar ratio and fission track methods of age dat-ing samples.

Analytical Equipment The Radiatio!1 Center has a large variety of radiation detec-tion instrumentation. 1bis equipment 'is upgraded as neces-sary, especially the gamma ray spectrometers with their associated computers and germanium detectors. Additional equipment for classroom use and an extensive inventory of portable radiation detection instrumentation are also avail-able.

Radiation Center nuclear instrumentation receives intensive -

e in both teaching and research applications. In addition, service projects also use these systems arid the combined use often results in 24-hour per day schedules for many of the analytical instruments. Use of Radiation Center equipment extends beyond that located at the Center and instrumentation may be made.available on a loan basis to OSU researchers in other departments.

Radioisotope Irradiation Sources The Radiation Center is equipped with a _10,200 curie (as of June, 2015) Gammacell 220 tiOCo irradiator which is capable of delivering high doses of gamma radiation over a range of dose rates to a variety of materials.

1ypically, the irradiator is used by researchers wishing to perform mutation and other biological effects studies; studies in the area of radiation chemistry; dosimeter testing; steril-ization of food materials, soils, sediments, biological speci-men, and other media; gamma radiation damage studies; and other such applications. In addition to the 60Co irradiator, the Center is also equipped with a variety of smaller 60Co, 137Cs, 226Ra, plutonium-beryllium, and other isotopic sealed sources of various radioactivity levels which are available for use as irradiation sources.

During this reporting period there was a diverse group of projects using the 60Co irradiator. These projects included the irradiation of a variety of biological materials including dif-ferent types of seeds.

2019-2020 ©

FAC.1 LITI ES In addition, the irradiator was used for sterilization of several media and the evaluation of the radiation effects on different materials. Table ID. I provides use data for the Gammacell 220 irradiator.

Laboratories and Classrooms The Radiation Center is equipped with a number of different radioactive material laboratories designed to accommodate research projects and classes offered by various OSU aca-demic departments or off-campus groups.

Instructional facilities available at the Center include a labo-ratory especially equipped for teaching radiochemistry and a nuclear instrumentation teaching laboratory equipped with modular sets of counting equipment which can be configured to accommodate a variety of experiments involving the mea-surement of many types of radiation. The Center also has two student computer rooms.

In addition to these dedicated instructional facilities, many other research laboratories and pieces of specialized equip-ment are regularly used for teaching. In particular, classes are routinely given access to gamma spectrometry equipment located in Center laboratories. A number of classes also regu-larly use the OS1R and the Reactor Bay as an integral part of their instructional coursework.

There are two classrooms in the Radiation Center which are capable ofholding about 35 and 18 $tudents. In addition, there are two smaller conference rooms and a library suitable for graduate classes and thesis examinations. As a service to the student body, the Radiation Center also provides an office area for the student chapters of the American Nuclear Society and the Health Physics Society.

All of the laboratories and classrooms are used extensively during the academic year. A listing of courses accommodated at the Radiation Center during this reporting period along with their enrollm~ts is given in Table ID.2.

Instrument Repair & Calibration Facility The Radiation Center has a facility for the repair and calibra-tion of essentially all types of radiation monitoring instru-mentation. This includes instruments for the detection and measurement of alpha, beta, gamma, and neutron radiation.

It encompasses both high range instruments for measuring

~

Annual Report intense radiation fields and low range instruments used to measure environmental levels of radioactivity.

The Center's instrument repair and cahbration facility is used regularly throughout the year and is absolutely essential to the continued operation of the many different programs carried out at the Center. In addition, the absence of any comparable facility in the state has led to a greatly expanded instrument calibration program for the Center, including cahbration of es-sentially all radiation detection instruments used by state and federal agencies in the state of Oregon. This includes instru-ments used on the OSU campus and all other institutions in the Oregon University System, plus instruments from the Oregon Health Division's Radiation Protection Services, the Oregon Department of Energy, the Oregon Public Utilities Commis-sion, the Oregon Health and Sciences University, the Army Corps of Engineers, and the U.S. Environmental Protection Agency.

Library The Radiation Center has a library containing a significant col-lections of texts, research reports, and videotapes relating to nuclear science, nuclear engineering, and radiation protection.

The Radiation Center is also a regular recipient of a great vari-ety of publications from commercial publishers in the nuclear field, from many of the professional nuclear societies, from the U.S. Department of Energy, the U.S. Nuclear Regula-tory Commission, and other federal agencies. Therefore, the Center library maintains a current collection of leading nuclear research and regulatory documentation. In addition, the Center has a collection of a number of nuclear power reactor Safety Analysis Reports and Environmental Reports specifically prepared by utilities for their facilities.

'The'Center maintains an up-to-date set of reports from such organiz.ations as the International Commission on Radiological Protection, the National Council on Radiation Protection and Measurements, and the International Commission on Radio-logical Units. Sets of the current U.S. Code of Federal Regula-tions for the U.S. Nuclear Regulatory Commission, the U.S.

Department of Transportation, and other appropriate federal agencies, plus regulations of various state regulatory agencies are also available at the Center.

The Radiation Center videotape library has over one hundred tapes on nuclear engineering, radiation protection, and radio-logical emergency response topics. In addition, the Radiation

Center uses videotapes for most of the technical orientations which are required for personnel working with radiation and radioactive materials. These tapes are reproduced, recorded, and edited by Radiation Center staff, using the Center's video-tape equipment and the facilities of the OSU Communication Media Center.

The Radiation Center library is used mainly to provide refer-ence material on an as-needed basis. It receives extensive use during the academic year. In addition, the orientation video-tapes are used intensively during the beginning of each term and periodically thereafter.

Radiation Protection Introduction The purpose of the radiation protection program is to ensure the safe use of radiation and radioactive material in the Cen-ter's teaching, research, and service activities, and in a similar manner to the fulfillment of all regulatory requirements of the State of Oregon, the U.S. Nuclear Regulatory Commission, and other regulatory agencies. The comprehensive nature of the program is shown in Table V. I, which lists the program's major radiation protection requirements and the performance frequency for each item.

The radiation protection program is implemented by a staff consisting of a Senior Health Physicist, a Health Physicist, and several part-time Health Physics Monitors (see Part II).

Assistance is also provided by the reactor operations group, the neutron activation analysis group, the Scientific Instrument Technician, and the Radiation Center Director.

The data contained in the following sections hav nb je been prepared to comply with the current requirements of Nuclear Regulatory Commission (NRC) Facility License No. R-106 (Docket No. 50-243) and the Technical Specifications con-tained in that license. The material has also been prepared in compliance with Oregon Department of Energy Rule No.

345-30-0 I 0, which requires an annual report of environmental effects due to research reactor operations.

Within the scope of Oregon State University's radiation pro-tection program, it is standard operating policy to maintain all releases of radioactivity to the unrestricted environment and all exposures to radiation and radioactive materials at levels which are consistently "as low as reasonably achievable" (ALARA).

Annual Report Environmental Releases The annual reporting requirements in the OSTR Technical Specifications state that the licensee (OSU) shall include "a summary of the nature and amount of radioactive effluents released or discharged to the environs beyond the effective control of the licensee, as measured at, or prior to, the point of such release or discharge." The liquid and gaseous effluents released, and the solid waste generated and transferred are discussed briefly below. Data regarding these effluents are also summarized in detail in the designated tables.

Liquid Effluents Released Liquid Ejfluents Oregon State University has implemented a policy to reduce the volume of radioactive liquid effluents to an absolute mini-mum. For example, water used during the ion exchanger resin change is now recycled as reactor makeup water. Waste water from Radiation Center laboratories and the OSTR is collected at a holdup tank prior to release to the sanitary sewer. Liquid effluent are analyzed for radioactivity content at the time it is released to the collection point. For this reporting period, the Radiation Center and reactor made seven liquid effluent releases to the sanitary sewer. All Radiation Center and reactor facility liquid effluent data pertaining to this release are con-tained in Table V.2.

Liquid Waste Generated and Transferred Liquid waste generated from glassware and laboratory experi-ments is transferred by the campus Radiation Safety Office to its waste processing facility. The annual summary of liquid waste generated and transferred is contained in Table V.3.

Airborne Effluents Released Airborne effluents are discussed in terms of the gaseous com-ponent and the particulate component.

Gaseous Ejfluents Gaseous effluents from the reactor facility are monitored by the reactor stack effluent monitor. Monitoring is continuous, i.e., prior to, during, and after reactor operations. It is normal for the reactor facility stack effluent monitor to begin opera-tion as one of the first systems in the morning and to cease operation as one of the last systems at the end of the day. All gaseous effluent data for this reporting period are summarized in Table V.4.

Particulate effluents from the reactor facility are also moni-tored by the reactor facility stack effluent monitor.

Particulate Effluents.

Evaluation of the detectable particulate radioactivity in the stack effluent confirmed its origin as naturally-occurring radon daughter products, within a range of approximately 3xl 0-11

µCi/ml to 1 x lo-9 µCi/ml. This particulate radioactivity is predominantly 214Pb and 21413~ which is not associated with reactor operations.

There was no release of particulate effluents with a half life

• greater than eight days and therefore the reporting of the aver-age concentration of radioactive particulates with half lives greater than eight days is not applicable.

Solid Waste Released Data: for the radioactive material in the solid waste generated and transferred during this reporting period are summarized in Table V.5 for both the reactor facility and the Radiation Center.

Solid radioactive waste is routinely transferred to OSU Radia-tion Safety. Until this waste is disposed of.by the Radiation Safety Office, it is held along with other campus radioactive waste on the University's State of Oregon radioactive materi-als license.

Solid radioactive waste is disposed ofby OSU Radiation Safety by transfer to the University's radioactive waste dis-posal vendor.

Personnel Dose The OSTR annual reporting requirements specify that the licensee.shall present a summary of the radiation exposure received by facility personnel and visitors. The summary in-cludes all Radiation Center personnel who may* have received exposure to radiation. These personnel have been categorized into six groups: facility operating personnel, key facility research personnel, facilities services main~nance personnel, students in laboratqry classes, police and security personnel,-

and visitors.

Facility operating personnel include the reactor operations and health physics staff. The dosimeters used to monitor these in-dividuals include quarterly TLD badges, quarterly track-etch/

albedo neutron dosimeters, monthly 1LD (finger) extremity dosimeters, pocket ion chambers, electronic dosimetry.

Key facility research personnel consist of Radiation Center staff, faculty, and graduate* students who perform research RADIATION PROTECTION using the reactor, reactor~activated materials, or using other re~h facilities present at the Center. The individual dosim-etry requirements for these personnel will vary with the type of research being conducted, but will generally include a quar-terly 1LD film badge and 1LD (finger) extremity dosimeters.

If the possibility ofneutron exposure exists, researchers are also monitored with a track-etch/ albedo neutron dosimeter.

Facilities Services maintenance personnel are normally issued a gamma sensitive electronic dosimeter as their basic monitor-ing device.

Students attending laboratory classes are issued quarterly XB(y) 1LD badges, 1LD (finger) extremity dosimeters, and track-etch/albedo or other.neutron dosimeters, as appropriate.

Students or small groups of students who attend a one-time lab demonstration and do n9t handle radioactive materials are usually issued a gamma sensitive electronic dosimeter. These results are not included with the laboratory class students.

OSU police and security personnel are issued a quarterly XB(y) 1LD badge to be used during their patrols of the Radia-tion Center and reactor facility.

Visitors, depending on the locations visited, may be issued gamma sensitive electronic dosimeters. 6SU Radiation Center policy does not normally allow people in the visitor category to become actively involved in the use or handling of radioac-tive materials.

An annual summary of the radiation doses received by each of the above six groups is shown_in Table V.6. There were no personnel radiation exposures in excess of the limits in 10 CFR 20 or State of Oregon regulations during the reporting period. '

Facility Survey Data

_ The OSTR Technical Specifications require an annual sum*-

mary of the radiation levels and levels of contamination observed during routine surveys performed at the facility. The Center's comprehensive area radiation morlitoring program encompasses the Radiation Center as well as the OS1R, and therefore monitoring results for both facilities are reported.

Area Radiation Dosimeters Area monitoring dosimeters capable of integrating the radia-tion dose are located at strategic positions throughout the reactor facility and Radiati~n Center. All of these dosimeters contain at least a standard personnel-type beta-gamma film or 2019-2020

RADIATION PROTECTION TLD pack. In addition, for key locations in the reactor facility and for certain Radiation Center laboratories a CR-39 plas-tic track-etch neutron detector has also been included in the monitoring package.

The total dose equivalent recorded on the various reactor facil-ity dosimeters is listed in Table V.7 and the total dose equiva-lent recorded on the Radiation Center area dosimeters is listed in Table V.8. Generally, the characters following the Monitor Radiation Center (MRC) designator show the room number or location.

Routine Radiation and Contamination Surveys The Centers program for routine radiation and contamination surveys consists of daily, weekly, and monthly measurements throughout the 1RIGA reactor facility and Radiation Center.

The frequency of these surveys is based on the nature of the radiation work being carried out at a particular location or on other factors which indicate that surveillance over a specific area at a defined frequency is desirable.

The primary purpose of the routine radiation and contamina-tion survey program is to assure regularly scheduled surveil-lance over selected work areas in the reactor facility and in the Radiation Center, in order to provide current and characteristic data on the status of radiological conditions. A second objec-tive of the program is to assure frequent on-the-spot personal observations (along with recorded data), which will provide advance warning of needed corrections and thereby help to ensure the safe use and handling of radiation sources and radioactive materials. A third objective, which is really derived from successful execution of the first two objectives, is to gather and document information which will help to ensure that all phases of the operational and radiation protection programs are meeting the goal of keeping radiation doses to personnel and releases of radioactivity to the environment "as low as reasonably achievable" (ALARA).

The annual summary of radiation and contamination levels measured during routine facility surveys for the applicable reporting period is given in Table V.9.

Environmental Survey Data The annual reporting requirements of the OSTR Technical Specifications include "an annual summary of environmental surveys performed outside the facility."

@; Annuat Report Gamma Radiation Monitoring On-site Monitoring Monitors used in the on-site gamma environmental radiation monitoring program at the Radiation Center consist of the re-actor facility stack effluent monitor descnbed in Section V and nine environmental monitoring stations.

During this reporting peri~ each fence environmental station utilized an LiF TLD monitoring packet supplied and proc~ed by Mirion Technologies, Inc., Irvine, California Each packet contained three LiF TLDs and was exchanged quarterly for a total of 108 samples during the reporting period (9 stations x 3 TLDs per station x 4 quarters). The total number ofTLD samples for the reporting period was 108. A summary of the TLD data is also shown in Table V.10.

From Table V.10 it is concluded that the doses recorded by the dosimeters on the 1RIGA facility fence can be attnbuted to natural back-ground radiation, which is about 110 mrem per year for Oregon (Refs. 1, 2).

Off-site Monitoring The off-site gamma environmental radiation monitoring program consists of twenty monitoring stations surrounding the Radiation Center (see Figure V.1) and six stations located within a 5 mile radius of the Radiation Center.

Each monitoring station is located about four feet above the ground (MRCTE 21 and MRCTE 22 are mounted on the roof of the EPA Laboratory and National Forage Seed Laboratory, respectively). These monitors are exchanged and processed quarterly, and the total number ofTLD samples during the cur-rent one-year reporting period was 240 (20 stations x 3 chips per station per quarter x 4 quarters per year). The total number ofTLD samples for the reporting period was 240. A summary ofTLD data for the off-site monitoring stations is given in Table V.Jl.

After a review of the data in Table V.11, it is concluded that,*

like the dosimeters on the 1RIGA facility fence, all of the doses recorded by the off-site dosimeters can be attnbuted to natural background radiation, which is about 110 mrem per year for Oregon (Refs. 1, 2).

Soil, Water, and Vegetation Surveys The soil. water, and vegetation monitoring program consists of the collection and analysis of a limited number of samples in each category on a annual basis. The program monitors highly unlikely radioactive material releases from either the 1RIGA I

• reactor facility or the OSU Radiation Center, and also helps indicate the general trend of the radioactivity concentration in each of the various substances sampled. See Figure V l for the locations of the sampling stations for grass (G), soil (S), water (W) and rainwater (RW) samples. Most locations are within a 1000 foot radius of the reactor facility and the Radiation Center. In general, samples are collected over a local area having a radius of about ten feet at the positions indicated in Figure V 1.

There are a total of 22 sampling locations: four soil loca-tions, four water locations (when water is available), and fourteen vegetation locations.

The annual concentration of total net beta radioactivity (mi-nus tritium) for samples collected at each environmental soil, water, and vegetation sampling location (sampling station) is listed in Table V 12. Calculation of the total net beta disinte-gration rate incorporates subtraction of only the counting sys-tem back-ground from the gross beta counting rate, followed by application of an appropriate counting system efficiency.

The annual concentrations were calculated using sample results which exceeded the lower limit of detection (LLD),

except that sample results which were less than or equal to the LLD were averaged in at the corresponding LLD con-centration. Table V 13 gives the concentration and the range of values for each sample category for the current reporting period.

As used in this report, the LLD has been defined as the amount or concentration of radioactive material (in terms of

µCi per unit volume or unit mass) in a representative sample, which has a 95% probability of being detected.

RADIATION PROTECTION Identification of specific radionuclides is not routinely carried out as part of this monitoring program, but would be conduct-ed if unusual radioactivity levels above natural background were detected. However, from Table V 12 it can be seen that the levels ofradioactivity detected were consistent with naturally occurring radioactivity and comparable to values reported in previous years.

Radioactive Materials Shipments A summary of the radioactive material shipments originating from the TRIG A reactor facility, NRC license R-106, is shown in Table V 14. A similar summary for shipments originating from the Radiation Center's State of Oregon radioactive ma-terials license ORE 90005 is shown in Table Vl5. A summary of radioactive material shipments exported under Nuclear Regulatory Commission general license 10 CFR 110.23 is shown in Table V 16.

-W-ork Summary The Radiation Center offers a wide variety ofresources for teaching, research, and service related to radiation and radioac-tive materials. Some of these are discussed in detail in other parts of this report. The purpose of this section is to sum-marize the teaching, research, and service efforts carried out during the current reporting period.

Teaching An important responsibility of the Radiation Center and the reactor is to support OSU's academic programs. Implementa-tion of this support occurs through direct involvement of the Center's staff and facilities in the teaching programs of various departments and through participation in University research programs. Table III.2 plus the "Training and lnstuction" sec-tion (see next page) provide detailed information on the use of the Radiation Center and reactor for instruction and training.

Research and Service Almost all Radiation Center research and service work is tracked by means of a project database. When a request for facility use is received, a project number is assigned and the project is added to the database. The database includes such information as the project number, data about the person and institution requesting the work, information about students in-volved, a description of the project, Radiation Center resources needed, the Radiation Center project manager, status of indi-vidual runs, billing information, and the funding source.

Table VI. I provides a summary of institutions which used the Radiation Center during this reporting period. This table also includes additional information about the number of academic personnel involved, the number of students involved, and the number of uses logged for each organization.

The major table in this section is Table VI.2. This table provides a listing of the research and service projects carried out during this reporting period and lists information relating to the personnel and institution involved, the type of project, and the funding agency. Projects which used the reactor are indicated by an asterisk. In addition to identifying specific projects carried out during the current reporting period, Part Annual Report VJ also highlights major Radiation Center capabilities in research and service. These unique Center functions are described in the following text.

Neutron Activation Analysis Neutron activation analysis (NAA) stands at the forefront of tech-niques for the quantitative multi-element analysis of major, minor, trace, and rare elements. The principle involved in NAA consists of first irradiating a sample with neutrons in a nuclear reactor such as the OSTR to produce specific radionuclides. After the irradiation, the characteristic gamma rays emitted by the decaying radionu-clides are quantitatively measured by suitable semiconductor radia-tion detectors, and the gamma rays detected at a particular energy are usually indicative of a specific radionuclide's presence. Com-puterized data reduction of the gamma ray spectra then yields the concentrations of the various elements in samples being studied.

With sequential instrumental NAA it is possible to measure quanti-tatively about 35 elements in small samples (5 to 100 mg), and for activable elements the lower limit of detection is on the order of parts per million or parts per billion, depending on the element.

The Radiation Center's NAA laboratory has analyzed the major, minor, and trace element content of tens of thousands of samples covering essentially the complete spectnnn of material types and involving virtually every scientific and technical field.

While some researchers perform their own sample counting 6n their own or on Radiation Center equipment, the Radia-C "d

J tion enter prov1 es a complete NAA service for researchers and others who may require it. This includes sample prepara-tion, sequential irradiation and counting, and data reduction and analysis.

I"adiations As descnbed throughout this report, a major capability of the Radiation Center involves the irradiation of a large variety of substances with gamma rays and neutrons. Detailed data on these irradiations and their use are included in Part ID as well as in the "Research & Service" text of this section.

Radiological Emergency Response Services The Radiation Center has an emergency response team capable of responding to all types of radiological accidents.

This team directly supports the City of Corvallis and Benton County emergency response organizations and_ medical fa-cilities. The team can also provide assistance at the scene of any radiological incident anywhere in the state of Oregon 9n behalf of the Oregon Radiation Protection Services and the Oregon Department of Energy.

The Radiation Center maintains dedicated stocks of radio-logical emergency response equipment and instnnnentation.

Toes~ items are located at the Radiatj.on Center and at the Good Samaritan Hospital in Corvallis.

During the current reporting period, the Radiation Center emergency response ~

conducted several qaining ses-sions arid exercises, but was not required to respond to any actual incidents.

Training anr} Instruction In addition to the academic laboratory classes and courses discussed in Parts ID and VI, and in ~ddition to the routine training needed to meet the requirements of the OS1R Emer-gency Response Plan, Physical Security Plan, and operator requali:fication program, the Radiation Center is also used for special training programs. Radiation Center staff are well ex-perienced in conducting these special* programs and regularly offer training in areas such as research reactor operations, WORK research reactor management, research reactor radiation protection, radiological emergency response, reactor behav-ior (for nuclear power plant operators), neutron activation analysis, nuclear chemistry, and nuclear safety analysis.

Special training programs generally fall into one of several categories: visiting faculty and research scientists; Interna-tional Atomic Energy Agency fellows; special short-term courses; or individual reactor operator o~ health physics training*programs. During this reporting period there were a

_, large number of such people as shown in the People Section.

As has been the practice since 1985, Radiation Center personnel annually present a HAZMAT Response Team Ra-*

diological Course. This year the course was held at Oregon State University.

Radiation Protection Services The primary purpose of the radiation protection program at the Radiation Center is to support the instruction and research conducted at the Center. However, due to the high quality of the program and the level of expertise and equip-ment available, the Radiation Center is also able to provide health physics services in support of OSU Radiation Safety and to assist other state and federal agencies. The Radiation Center does not compete with private industry, but supplies heal~ physics services which are not readily available else-where. In the case of support provided to state agencies~ this definitely helps to optimize the utilization of state resources.

The Radiation Center is capable of providing health phys-ics services in any of the areas which are discussed in Part V. These include personnel monitoring, radiation surveys, sealed source leak testing, packaging and shipment of radio-active materials, calibration and repair of radiation monitor-ing instruments ( qiscussed in detail in Part VI), radioactive waste disposal, radioactive material hood flow surveys, and radiation safety analysis and audits.

The Radiation Center also provides services and technical support as a radiation laboratory to the'State of Oregon Radi-ation Protection Services (RPS) in the event of a radiological emergency within the state of Oregon. In this role, the Radia-

. tion Center will provide gamma ray spectrometric analysis of water, soil, milk, food products, vegetation, and air samples collected by RPS radiological response field teams. As part of the ongoing preparation for this emergency support, the Radiation Center participates in inter-institution drills.

2019' - 2020 @

WORK Radiological Instrument Repair and Calibration While repair ofnuclear instrumentation is a practical neces-sity, routine calibration of these instruments is a licensing and regulatory requirement which must be met. As a result, the Radiation Center operates a radiation instrument repair and cah"bration facility which can accommodate a wide vari-ety of equipment The Center's scientific instrument repair facility performs maintenance and repair on all types of radiation detectors and other nuclear instrumentation. Since the Radiation Cen-ter's own programs regularly utilize a wide range of nuclear instruments, components for most common repairs are often on hand and repair time is therefore minimized.

In addition to the instrument repair capability, the Radia-tion Center has a facility for calibrating essentially all types of radiation monitoring instruments. This includes typical portable monitoring instrumentation for the detection and measurement of alpha, beta, gamma, and neutron radiation, as well as instruments designed for low-level environmental monitoring. Higher range instruments for use in radiation accident situations can also be cahbrated in most cases.

Instrument calibrations are performed using radiation sources certified by the National Institute of Standards and Technology (NISl) or traceable to NIST.

Table VI.3 is a summary of the instruments which were cali-brated in support of the Radiation Center's instructional and research programs and the OSTR Emergency Plan, while Table VI.4 shows instruments calibrated for other OSU departments and non-OSU agencies.

Consultation Radiation Center staff are available to provide consultation ser-vices in any of the areas discussed in this Annual Report, but in particular on the subjects of research reactor operations and use, radiation protection, neutron activation analysis, radiation shielding, radiological emergency response, and radiotracer methods.

Records are not normally kept of such consultations, as they often take the form of telephone conversations with research-ers encountering problems or planning the design of experi-ments. Many faculty members housed in the Radiation Center have ongoing professional consulting functions with various organizations, in addition to sitting on numerous committees in advisory capacities.

Neutron-induced fission tracks are essential to the etching experiments because neutron-induced fission tracks, as compared to natuially occurring fission tracks, have no thermal history ( or thermal annealing effects).
