Acknowledgements We have experienced yet another exciting and successful year. There are many people to thank for this but most of the credit goes to the staff. Steve, Dina, Erin, Shirley, Todd, Gary, Jim, Beth, Alena, Leah, and Scott. Without their efforts none of this

• would be possible. The camaraderie and

• cooperation of this group has created a sense of accomplishment and fulfillment rarely seen in organizations of this size.

0 nuclear engineering students can learn how the reactor works in the classroom, then apply the knowledge ii We had two individuals who departed the Radiation Center this year and we wish both of them the best. After some thirty years, Mike Conrady retired to be closer

• to family. While Mike leaves a legacy of 0 NAA analysis, computers, and networks,

• it was his outreach and activities involv-

• ing students for which he had his greatest

• impact. Mike Hartman who, although he

• was with us for only a short time, contrib-uted more to the Radiation Center both personally and professionally than we have

• seen from any individual in many years.

• T-here are many things we simply could not

• have done without him. They both will be

• missed.

0 PartI-Overview Tedata from this reporting year shows that the use of the Radiation 0 Center and the Oregon State TRIGA reactor (OSTR) has continued/

to grow in many areas.

TeRadiation Center supported 48 different courses this year, mostly in the Department of Nuclear l

Engineering and Radiation Health Physics. About 3 1% of these courses involved the OSTR. The number of OSTR hours used for academic courses and training was 56, while 2,851 hours0.00985 days <br />0.236 hours <br />0.00141 weeks <br />3.238055e-4 months <br /> were used for research projects. Seventy-eight percent 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 published or submit-ted 86 articles this year, completed 6 theses/dissertations, and made 53 presentations on work that involved0 the OSTR or Radiation Center. The number of samples irradiated in the reactor during this reportingS period was 2018. Funded OSTR use hours comprised 96% of the research use.

Personnel at the Radiation Center conducted 148 tours of the facility, accommodating 2,189 visitors. The0 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 visi-tors leave with a good impression of the facility and of Oregon State University.0 The Radiation Center projects database continues to provide a useful way of tracking the many different0 aspects of work at the facility. The number of projects supported this year was 220. Reactor related projects comprised 73% of all projects. The total research supported by the Radiation Center, as reported by our researchers, was $5,769,460. The actual total is likely considerably higher. This year the Radiation Center provided service to 69 different organizations/ institutions, 38% of which were from other states and 16%

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 capabilities as well as to apply for a project and check use charges. The address is: http://radiationcenter.

The current annual report of the Oregon State University Radiation Center and TRIGA Reactor follows the usual format by including information relating to the entire Radiation Center rather than just the reac-tor. 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 1, 2006 through June 30, 2007. Cumulative reactor operating data in this report relate only to the FLIP-fu-eled core. Tbis covers the period from August 1, 1976 through June 30, 2007. For a summary of data on the reactor's original 20% enriched core, the reader is referred to Table IVA.2 in Part IV of this report or to the 1976-77 Annual Report if a more comprehensive review is needed.t0 OtSU Radiation Center 6

0 0 In addition to providing general information about the activities of the Radiation Center, this report is de-

• signed to meet the reporting requirements of the U. S. Nuclear Regulatory Commission, the U. S. Depart-ment 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.

0 The Radiation Center is a unique facility which serves the entire OSU campus, all other institutions within the Oregon University System, and many other universities and organizations throughout the nation and the world. The Center also regularly provides special services to state and federal agencies, particularly 0 agencies dealing with law enforcement, 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 Department of Nuclear Engineering and Radiation Health Physics, the OSU Institute of Nuclear Science and Engineering, and for the OSU nuclear chemistry, radiation chemistry, geochemistry and S radiochemistry programs. There is no other university facility with the combined capabilities of the OSU

• The Oregon State University TRIGA 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 of0 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 licensed by the U.S. Nuclear Regulatory Commission to operate at a maximum steady state0 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 irra-diations, an in-core irradiation tube, and a cadmium-lined in-core irradiation tube for experiments requiring a high energy neutron flux. The OSTR also has an Argon Production Facility for the production of 4lAr.0 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 activation 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 of a circular array of 40 tubular positions, each of which can hold two sample tubes. 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 column to enable0 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. One of the beam ports contains the argon production facility for production of curie levels of 41Ar. The neutron radiogra-phy facility utilized the tangential beam port (beam port #3) to produce ASTM E545 category I radiogra-phy 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 may0 be inserted into a dummy fuel element. This device will then be placed into one of the core's inner grid posi-tions which would normally 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 cadmium-lined in-core irradiation tube (CLICIT) enables samples to be irradiated in a high flux region near the center of the core. The cadmium lining in the facility eliminates thermal neutrons and thus permits sample exposure to higher energy neutrons only. The cadmium-lined end of this air-filled aluminum0 irradiation tube is inserted into an inner grid position of the reactor core which would normally be occupied by a fuel element. It is the same as the ICIT except for the presence of the cadmium lining.

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

Instruction Instructional use of the reactor is twofold. First, it is used significantly for classes in Nuclear Engineering, Radiation Health Physics, and Chemistry at both the graduate and undergraduate levels to demonstrate numerous 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 experiments are also performed for many undergraduate students in Physics, Chemistry, and Biology classes, as well as for visitors from other universities and colleges, from high schools, and from

• public groups.

0 The second instructional application of the OSTR involves educating reactor operators, operations man-

• agers, 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 Radiation Center provides 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 sup-

• ported by the OSTR. Table III.D.1, provides detailed information on the use of the OSTR for instruction

• and training.

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 described in more detail in Part VI.

• The OSTRs irradiation facilities provide a wide range of neutron flux levels and neutron flux qualities which are sufficient to meet the needs of most researchers. This is true not only for INAA, but also for other experimental purposes such as the 39Ar/4OAr ratio and fission track methods of age dating samples.

0 The Radiation Center has a large variety of radiation detection instrumentation. This equipment is upgrad-ed as necessary, especially the gamma ray spectrometers with their associated computers and germanium detectors. Additional equipment for classroom use and an extensive inventory of portable radiation detec-tion instrumentation are also available.

Radiation Center nuclear instrumentation receives intensive use in both teaching and research applications.

O In addition, service projects also use these systems and 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

• The Radiation Center is equipped with a 1,644 curie (as of 7/27/01) Gammacell 220 60Co irradiator which is capable of delivering high doses of gamma radiation over a range of dose rates to a variety of mate-rials.

Typically, the irradiator is used by researchers wishing to perform mutation and other biological effects stud-ies; studies in the area of radiation chemistry; dosimeter testing; sterilization of food materials, soils, sedi-ments, biological specimen, 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 different types of seeds.

In addition, the irradiator was used for sterilization of several media and the evaluation of the radiation effects on different materials. Table III.C.1 provides use data for the Gammacell 220 irradiator.

Labovacoeis adCB ss vw s 0 The Radiation Center is equipped with a number of different radioactive material laboratories designed to accommodate research projects and classes offered by various OSU academic departments or off-campus groups.

Instructional facilities available at the Center include a laboratory especially equipped for teaching radiochem-istry 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 measurement of many types of radiation. The Center also has two student computer rooms equipped with a large number of personal computers and UNIX workstations.

In addition to these dedicated instructional facilities, many other research laboratories and pieces of special-ized equipment 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 regularly use the OSTR and the Reactor Bay as an integral part of their instructional coursework.

There are two classrooms in the Radiation Center which are capable of holding about 35 and 18 students, respectively. 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.

This reporting period saw continued high utilization of the Radiation Center's thermal hydraulics laboratory.

This laboratory is being used by Nuclear Engineering faculty members to accommodate a one-quarter scale model of the Palisades Nuclear Power reactor. The multi-million dollar advanced plant experimental (APEX) facility was fully utilized by the U. S. Nuclear Regulatory Commission to provide licensing data and to test safety systems in"beyond design basis" accidents. The fully scaled, integral model APEX facility uses electri-cal heating elements to simulate the fuel elements, operates at 450'F and 400 psia, and responds at twice

• real time. It is the only facility of its type in the world and is owned by the U. S. Department of Energy and operated by OSU. In addition, a new building, the Air-water Test Loop for Advanced Thermal-hydraulics Studies (ATLATS), was constructed next to the Reactor Building in 1998. Two-phase flow experiments are conducted in the ATLATS. Together APEX and ATLATS comprise the Advanced Thermal Hydraulics Research Laboratory (ATHRL).

0 The Radiation Center is also a regular recipient of a great variety 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 Regulatory Commission, and other federal agencies. Therefore, the Center library maintains a cur-rent 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 0 by utilities for their facilities.

0 The Center maintains an up-to-date set of reports from such organizations as the International Commission on 0 Radiological Protection, the National Council on Radiation Protection and Measurements, and the International Commission on Radiological Units. Sets of the current U.S. Code of Federal Regulations for the U.S. Nuclear Regulatory Commission, the U.S. Department of Transportation, and other appropriate federal agencies, plus 0 regulations of various state regulatory agencies are also available at the Center.

0 The Radiation Center videotape library has over one hundred tapes on nuclear engineering, radiation protection, and radiological 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.

Reactor power generation for the operating period between July 1, 2006 and June 30, 2007 totaled 1328 MWH of thermal power. This is equal to 55 MWD of generation, and results in a cumulative thermal output by the OSTR FLIP core of 1211 MWD from August 1976 through June 30, 2007.

Table IV.A.1 provides information related to the OSTR annual energy production, fuel usage and use re-quests. Table IV.A.2 summarizes statistics for the original 20% enriched fuel loading.

The productivity of the reactor irradiation facilities is based on reactor operation in relation to use categories.

Greater productivity is achieved by utilizing a greater number of irradiation facilities at the same time. Tables IV.A.3 through 5 provide this years detail on reactor use and other tracked data.

A normal nine-hour, five-day per week schedule sets the total available reactor operating hours. Critical reac-tor operation averaged 60% of each day.

PartV-Radiation Protection Q0 0

The purpose of the radiation protection program is to ensure the safe use of radiation and radioactive material in the Center's teaching, J research, and service activities, and in a similar manner to ensure 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.A.1, 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.F). 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 have been prepared to comply with the current requirements of Nuclear Regulatory Commission (NRC) Facility License No. R-106 (Docket No. 50-243) and the Techni-cal Specifications contained in that license. The material has also been prepared in compliance with Oregon Department of Energy Rule No. 345-30-010, which requires an annual report of environmental effects due to research reactor operations.

Within the scope of Oregon State University's radiation protection 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).

0 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.

0 ILho-lud FFlems Meased Liquid Effluents Oregon State University has implemented a policy to reduce the volume of radioactive liquid effluents to an absolute minimum. 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. Whenever possible, liquid effluent is analyzed for radioactivity content at the time it is released to the collection point. However, liquids are always analyzed for radioactivity before the holdup tank is discharged into the unrestricted area (the sanitary sewer system). For this reporting pe-riod, the Radiation Center and reactor made two liquid effluent releases to the sanitary sewer. All Radiation Center and reactor facility liquid effluent data pertaining to this release are contained in Table V.B.1.A.

OSU Radiation Center 42 0

0 Liquid Waste Generated and Transferred Liquid waste generated from glassware and laboratory experiments 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.B. 1.b.

• nc v Ia§ RDL e 0 Airborne effluents are discussed in terms of the gaseous component and the particulate component.

0Gaseous Effluents 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 efflu-ent monitor to begin operation 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 S V.B.2.

• Particulate effluents from the reactor facility are also monitored by the reactor facility stack effluent monitor.

0Particulate Effluents Evaluation of the detectable particulate radioactivity in the stack effluent confirmed its origin as naturally-oc-

• curring radon daughter products, within a range of approximately 3 x 10-11 laCi/ml to 1 x 10-9 piCi/ml. This particulate radioactivity is predominantly 214Pb and 214Bi, 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 average concentration of radioactive particulates with half lives greater than eight days is not applicable.

0 0

• Safld Was [ease-

• Data for the radioactive material in the solid waste generated and transferred during this reporting period are summarized in Table V.B.3 for both the reactor facility and the Radiation Center. Solid radioactive waste is routinely transferred to OSU Radiation 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 materials

• license.

Solid radioactive waste is disposed of by OSU Radiation Safety by transfer to the University's radioactive waste disposal vendor, Thomas Gray Associates, Inc., for burial at its installation located near Richland, Washington.

• pevsaneM Dose

• The OSTR annual reporting requirements specify that the licensee shall present a summary of the radia-tion exposure received by facility personnel Doses and visitors. For the purposes of this report, the summary includes all Radiation Center personnel who may have received exposure to radiation. These personnel have 0been categorized into six groups: facility operating personnel, key facility research personnel, facilities services maintenance personnel, students in laboratory classes, police and security personnel, and visitors.

0 Facility operating personnel include the reactor operations and health physics staff The dosimeters used to monitor these individuals include quarterly TLD badges, quarterly track-etch/albedo neutron dosimeters, monthly TLD (finger) extremity dosimeters, and pocket ion chambers.

Key facility research personnel consist of Radiation Center staff, faculty, and graduate students who per-form research using the reactor, reactor-activated materials, or using other research facilities present at the Center. The individual dosimetry requirements for these personnel will vary with the type of research being conducted, but will generally include a quarterly TLD film badge and TLD (finger) extremity dosimeters. If the possibility of neutron exposure exists, researchers are also monitored with a track-etch/ albedo neutron dosimeter.

0 Facilities Services maintenance personnel are normally issued a gamma sensitive electronic dosimeter as their basic monitoring device. A few Facilities Services personnel who routinely perform maintenance on mechanical or refrigeration equipment are issued a quarterly XB(y) TLD badge and other dosimeters as ap-propriate for the work being performed.

Students attending laboratory classes are issued quarterly X13(G) TLD badges, TLD (finger) extremity dosimeters, and track-etch/albedo or other neutron dosimeters, as appropriate.

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

OSU police and security personnel are issued a quarterly XS(y) TLD badge to be used during their patrols of the Radiation Center and reactor facility.

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

An annual summary of the radiation doses received by each of the above six groups is shown in Table V.C.1.

There were no personnel radiation exposures in excess of the limits in 10 CFR 20 or State of Oregon regula-tions during the reporting period.

FaolK Surwy [Da0 0 The OSTR Technical Specifications require an annual summary of the radiation levels and levels of contam-ination observed during routine surveys performed at the facility. The Center's comprehensive area radiation monitoring program encompasses the Radiation Center as well as the OSTR, and therefore monitoring results for both facilities are reported.

Area RadiationDosimeters Area monitoring dosimeters capable of integrating the radiation dose are located at strategic positions throughout the reactor facility and Radiation Center. All of these dosimeters contain at least a standard personnel-type beta-gamma film or TLD pack. In addition, for key locations in the reactor facility and for certain Radiation Center laboratories a CR-39 plastic track-etch neutron detector has also been included in the monitoring package.

The total dose equivalent recorded on the various reactor facility dosimeters is listed in Table V.D.1 and the total dose equivalent recorded on the Radiation Center area dosimeters is listed in Table V.D.2. Generally, the characters following the Monitor Radiation Center (MRC) designator show the room number or loca-tion.

0 Routine Radiation and ContaminationSurveys The Center's program for routine radiation and contamination surveys consists of daily, weekly, and monthly measurements throughout the TRIGA 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 contamination survey program is to assure regularly scheduled surveillance 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 objective of the 0 program is to assure frequent on-the-spot personal observations (along with recorded data), which will pro-

• vide 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 S 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).

0 The annual summary of radiation and contamination levels measured during routine facility surveys for the

• applicable reporting period is given in Table V.D.3.

'

The annual reporting requirements of the OSTR Technical Specifications include "an annual summary of

• environmental surveys performed outside the facility" 0 On-site Monitoring Monitors used in the on-site gamma environmental radiation monitoring program at the Radiation Center

• consist of the reactor facility stack effluent monitor described in Section VB.2 and nine environmental moni-

• toring stations.

• During this reporting period, each fence environmental station utilized an LiF TLD monitoring packet sup-

• plied and processed by Global Dosimetry Solutions, Inc. (GDS), Irvine, California. Each GDS packet con-tained 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 of GDS TLD samples for the reporting

• period was 108. A summary of the GDS TLD data is also shown in Table VE.1.

• From Table VE.1 it is concluded that the doses recorded by the dosimeters on the TRIGA facility fence can

• be attributed 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.E.2) 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 0 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 of TLD samples during the current one-year reporting period was 240 (20 stations x 3 chips per station per quarter x 4 quarters per year). The total number of GDS TLD samples for the reporting period was 204. A summary of GDS TLD data for the

• off-site monitoring stations is given in Table V.E.2.

0

• 45 06-07 Annual Report

0 After a review of the data in Table V.E.2, it is concluded that, like the dosimeters on the TRIGA facility fence, all of the doses recorded by the off-site dosimeters can be attributed to natural background radiation, 0 which is about 110 mrem per year for Oregon (Refs. 1, 2).

100 The soil, water, and vegetation monitoring program consists of the collection and analysis of a limited num-ber of samples in each category on a annual basis. The program monitors highly unlikely radioactive material releases from either the TRIGA 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.E.1 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.E.1.

There are a total of 22 sampling locations: four soil locations, four water locations (when water is available),

and fourteen vegetation locations.

The annual concentration of total net beta radioactivity (minus tritium) for samples collected at each environmental soil, water, and vegetation sampling location (sampling station) is listed in Table V.E.3.

Calculation of the total net beta disintegration rate incorporates subtraction of only the counting system 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 cor-responding LLD concentration. Table V.E.4 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 ýtCi per unit volume or unit mass) in a representative sample, which has a 95% probability of being detected.

Identification of specific radionuclides is not routinely carried out as part of this monitoring program, but would be conducted if unusual radioactivity levels above natural background were detected. However, from Table V.E.3 it can be seen that the levels of radioactivity detected were consistent with naturally occurring radioactivity and comparable to values reported in previous years.

A similar summary for shipments originating from the Radiation Center's State of Oregon radioactive materials license ORE 90005 is shown in Table V.F.2.

0 by suitable semiconductor radiation detectors, and the gamma rays detected at a particular energy are usually indicative of a specific radionuclide's presence. Computerized 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 quantitatively about 35 elements in small samples (5 to 100 mg), and for acti-

• vable elements the lower limit of detection is on the order of parts per million or parts per billion, depending

• D 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 spectrum of material types and involving virtually every scientific and technical field.

• \While some researchers perform their own sample counting on their own or on Radiation Center equipment, the Radiation Center provides a complete NAA service for researchers and others who may require it. This 0 includes sample preparation, sequential irradiation and counting, and data reduction and analysis.

Data on NAA research and service performed during this reporting period are included in Table VI.C.3.

0 Forensic Studies Neutron activation analysis can also be advantageously used in criminal investigations. The principle un-derlying such application usually involves matching trace element profiles in objects or substances by NAA.

0 This in turn can help identify materials or products (e.g., identify the manufacturer of a given object), and in

• some cases can match bullets and other materials recovered from a victim to similar materials obtained from suspects. Materials which have been analyzed by the Radiation Center for forensic purposes include bullets, metals, paint, fuses, coats, glass, meat, and salts.

• Forensic studies performed in this reporting period are included in the listings in Tables VI.C.1 and VI.C.3.

Irradiations As described 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 during this reporting period are included in Part III as well as in Section C of this part.

• RadiologicalEmergency 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 organi-zations and medical facilities. The team can also provide assistance at the scene of any radiological incident anywhere in the state of Oregon on behalf of the Oregon Radiation Protection Services and the Oregon Department of Energy.

The Radiation Center maintains dedicated stocks of radiological emergency response equipment and instru-mentation. These items are located at the Radiation Center and at the Good Samaritan Hospital in Corvallis.

During the current reporting period, the Radiation Center emergency response team conducted several train-ing sessions and exercises, but was not required to respond to any actual incidents.

Training and Instruction In addition to the academic laboratory classes and courses discussed in Parts III.A.2, III.D, and VI.B, and in addition to the routine training needed to meet the requirements of the OSTR Emergency Response Plan, Physical Security Plan, and operator requalification program, the Radiation Center is also used for special training programs. Radiation Center staff are well experienced in conducting these special programs and regularly offer training in areas such as research reactor operations, research reactor management, research 0

reactor radiation protection, radiological emergency response, reactor behavior (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; International Atomic Energy Agency fellows; special short-term courses; or individual reactor operator or health physics training programs. During this reporting period there were a large number of such people as shown in Part II.B.

As has been the practice since 1985, Radiation Center personnel annually present a HAZMAT Response Team Radiological Course. This year the course was held at the Oregon State University Radiation Center.

RadiationProtection Services The primary purpose of the radiation protection program at the Radiation Center is to support the instruc-tion and research conducted at the Center. However, due to the high quality of the program and the level of expertise and equipment available, the Radiation Center is also able to provide health physics services in sup-port of OSU Radiation Safety and to assist other state and federal agencies. The Radiation Center does not compete with private industry, but supplies health physics services which are not readily available elsewhere.

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 physics services in any of the areas which are discussed 0

in Part V. These include personnel monitoring, radiation surveys, sealed source leak testing, packaging and shipment of radioactive materials, calibration and repair of radiation monitoring instruments (discussed in 0 detail in Section VI.C.7), 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 Radiation Protection Services (RPS) in the event of a radiological emergency within the state of Oregon. In this role, the Radiation Center will provide gamma ray spectrometric analysis of water, soil, milk, 0 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.

RadiologicalInstrument Repair and Calibration 0 While repair of nuclear instrumentation is a practical necessity, routine calibration of these instruments is a licensing and regulatory requirement which must be met. As a result, the Radiation Center operates a radia-tion instrument repair and calibration facility which can accommodate a wide variety 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 Center's own programs regularly utilize a wide range of nuclear instruments, components for most common repairs are often on hand and repair time 0 is therefore minimized.

In addition to the instrument repair capability, the Radiation 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 calibrated in most cases. Instrument calibrations are performed using radiation sources certified by the National Institute of Standards and Technology (NIST) or traceable to NIST.

Table VI.C.4 is a summary of the instruments which were calibrated in support of the Radiation Center's Ai . . OSU Radiation Center 68

0 instructional and research programs and the OSTR Emergency Plan, while Table VI.C.5 shows instruments 0 calibrated for other OSU departments and non-OSU agencies. ~~j4 ~<

0 Consultation

~ ~

Radiation Center staff are available to provide consultation services in any of the areas discussed in this An- r) .~

S nual 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.

0 0 Records are not normally kept of such consultations, as they often take the form of telephone conversations with researchers encountering problems or planning the design of experiments. Many faculty members 0 housed in the Radiation Center have ongoing professional consulting functions with various organizations, 0 in addition to sitting on numerous committees in advisory capacities.

Public Relations The continued interest of the general public in the OSTR is evident by the number of people who have S toured the facility. See Table VI.F.1 for statistics on scheduled visitors.
