Oregon State University TRIGA Reactor (OSTR) Docket No. 50-243, License No. R-106 In accordance with section 6.7.e of the OSTR Technical Specifications we are hereby submitting the Oregon State University Radiation Center and TRIGA Reactor Annual Report for the period July 1, 2003 through June 30, 2004. The Annual Report continues the pattern established over the past few years by including information about the entire Radiation Center rather than concentrating primarily on the reactor. Because the report addresses a number of different interests, it is rather lengthy, but we have incorporated a short executive summary which highlights the Center's activities and accomplishments over the past year. The executive summary indicates that the Radiation Center has had yet another successful and productive year. I would like to emphasize that the achievements of this last year would not have been possible without the support and assistance we received from the invaluable programs administered by the USDOE. In particular, the Reactor Sharing program and the University Research Reactor Upgrades program are very cost-effective in providing invaluable support to the university reactor community and its users. I declare under penalty of perjury that the foregoing is true and correct. Executed on: 27A o

Part I OVERVIEW A. Acknowledgments Many individuals and organizations help the Radiation Center succeed, and in recognition of this, the staffof the Oregon State University (OSU) Radiation Center and TRIGA Reactor (OSTR) would like to extend its appreciation to all of those who contributed to the information and events contained in this report: to the University administration; to those who provided our funding, particularly the U. S. Department of Energy (USDOE) and the State of Oregon; to ourregulators; to the researchers, the students, and others who used the Radiation Center facilities; to OSU Facilities Services; and to OSU Department of Public Safety and the Oregon State Police. We most earnestly say, "Thank you." Putting this report together each year is a major effort for two people. This year, the burden of collecting the information, "twisting arms," and generally producing the extensive document before you was placed upon LaVon Mauer. Erin Cimbri has once again made collecting the information much easierby automating manyof the tables in this report. The amount ofperson-hours shehas saved all of us over the years is more than we probably would like to admit. A special "thanks" goes out to both of them. B. Executive Summary The data from this reporting year show that the use of the Radiation Center and OSTR has continued to grow in many areas. The Radiation Center supported 71 different courses this year, mostly in the Department of Nuclear Engineering. About 20% of these courses involved the OSTR. The number of OSTR hours used for academic courses and training was 16, while 1998 hours were used for research projects. Sixty percent of the OSTR research hours were mi support of off-campus research projects, which reflects the use of the OSTR nationally and internationally. Radiation Center users published 56 articles this year, with 7 more submitted for publication. There were also 35 theses completed and 56 presentations made by Radiation Center users. The number of samples irradiated in the reactor during this reporting period was 1845., Funded OSTR use hours comprised 99% of the research use. Personnel at the Radiation Center conducted 111 tours of the facility, accommodating 2075 visitors. The visitors included elementary, middle school, high school, and college students; Overview I - I

.-- a-relatives and friends; faculty; current and prospective clients; national laboratory and industrial l scientists and engineers; and state, federal and international officials. The Radiation Center is a signiicant positive attraction on campus because visitors leave with a good impression ofthe 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 180 Reactor projects comprised 74% of all projects. The total research supported by the Radiation Center, as reported by our researchers, was $5,999,860. The actual total is likely considerably higher. This year the Radiation Center provided service to 72 different organizations/ institutions, 42% of which were from other states and 18% 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://www.ne.orst.edu/facilities/radiationcenter. C. Introduction 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 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 cover the period from July 1, 2003 through June 30, 2004. Cumulative reactor l operating data in this report relate only to the FLIP-fueled core. This covers the period from August 1, 1976 through June 30, 2004. For a summary of data on the reactor's original 20% l enriched core, the reader is referred to Table IV.A.2 in Part IV of this report or to the 1976-77 l Annual Report if a more comprehensive review is needed. In addition to providing general information about the activities 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. l Because of this, the report is divided into several distinct parts so that the reader may easily find the sections of interest. D. Overview of the Radiation Center 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 l throughout the nation and the world. The Center also regularly provides special services to state and federal agencies, particularly agencies dealing with law enforcement, energy, health, Overview I - 2

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, the OSU Radiation Safety Office, the OSU Institute of Nuclear Science and Engineering and Radiation Health Physics, and for the OSU nuclear chemistry, radiation chemistry, geochemistry and cosmochemistry 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 major items of specialized equipment and unique teaching and research facilities. They include a TRIGA Mark II research nuclear reactor; a 60Co gamma irradiator; a large number of state-of-the art computer-based gamma radiation spectrometers and associated germanium detectors; and a variety of instruments for radiation 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; laboratories for plant experiments involving radioactivity; a facility for-repair and calibration of-radiation protection instrumentation; and facilities for packaging radioactive materials for shipment to national and international destinations. A major non-nuclear facility housed in the Radiation Center is the one-quarter scale thermal hydraulic advanced plant experimental (APEX) test facility for the Westinghouse AP600 reactor design. The AP600 is a next-generation nuclear reactor design which incorporates many passive safety features as well as considerably simplified plant systems and equipment. APEX operates at pressures up to 400 psia and temperatures up to 450'F using electrical heaters instead of nuclear-fuel. All major components of the AP600 are included in APEX and all systems are appropriately scaled to enable the experimental measurements to be used for safety evaluations and licensing of the full scale plant. This world-class facility meets exacting quality assurance criteria to provide assurance of safety as well as validity of the test results. Also housed in the Radiation Center is the Advanced Thermal Hydraulics Research Laboratory, which is used for state-of-the-art two-phase flow experiments, and the Nuclear Engineering Scientific Computing Laboratory. The Radiation Center staff regularly provides direct support 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, radiation dosimetry, environmental radioactivity, production of short-lived radioisotopes,; radiation shielding, nuclear instrumentation, emergency response, transportation of radioactive materials, instrument calibration, radiation health physics, radioactive waste disposal, and other related areas.

Part III Facilities

Part m., FACILITIES A. Research Reactor

1. Description The Oregon State UniversityTRIGA Reactor (OSTR) is a water-cooled, swirmingpool typeof 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 licensed by the U.S. Nuclear Regulatory Commirssion 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 thermalcolumn, fourbeamports, 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 experiments requiring ahighenergyneutronflux. The OSTR also has anArgonIrradiation Facility for the production of 4"Ar. 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-livedradionucides. Onthe otherhand, the rotating rack is usedformuchlonger irradiationofsamples (e.g., hours). Therackconsists of acirculararrayof4O tubularpositions, 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 fromthereactorcoreinorderto increase thermaln'eutron activationofsamples. Over 99% ofthe neutrons in the thermal column are thermal neutrons. Graphiteblocks areremoved from the thermal column to enable samples to be positioned inside for irradiation. The beam ports are tubular penetrations inthereactor's mainconcrete shield whichenableneutron and gamma radiation to stream'from the core when abeam port's shield plugs are removed. One ofthe beamports contains theArgon Production Facility forproduction ofcurielevels of"4 Ar. The other beam ports are available for a variety of experiments.

If samples which are to be irradiated require a large neutron fluence, especially from higher encrgy 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 normally be occupied by a fuel element. Similarly samples can be placed in the in-core irradiation tube (ICIT) which call be inserted in the same core location. The cadmium-lined in-core irradiation tube (CLICIT) enables samples to be irradiated in ahigh fluxiregion near thecenterofthe core. The cadmiumlining in the facilityeliminates thermal neutrons and thus permits sample exposure to higher energy neutrons only. Thecadmium-lined end ofthis air-filled aluminum irradiation tube is insertedinto aninniergrid positionofthereactorcore which would normallybeoccupiedbyafuelelement. It is the same as theICITexcept forthepresence of the cadmium lining.

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

a. Instruction Instructionaluseofthereactoris twofold. First, itis used significantly forclasses 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 wellas forvisitors fromotheruniversities andcolleges, fromhigh schools, and frompublic groups.

The second instructional application of the OSTR involves education ofreactoroperators, 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 Radiation Center provides are more fully described in Part VI of this report. During this reporting period the OSTR accommodated a number ofdifferent OSU academic classes and other academic programs. In addition, portions of classes from other Oregon universities werealso supportedbythe OSTR. Table lll.D. I, provides detailed information on the use of the OSTR for instruction and training. Facilities III -2 I

b. Research The OSTR is a unique and valuable tool for a wide variety ofresearch 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 OSTR's irradiation facilities provide a wide range ofneutron 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 3Ar/t0Ar ratio and fission track methods of age dating samples. B. Analytical Equipment

1. Description The Radiation Center has a large variety of radiation detection instrumentation. This equipment is upgraded as necessary, especially the gammaray spectrometers with their associated computers and germanium detectors. Additional equipment for classroom use and an extensive inventory of portable radiation detection instrumentation are also available.

2. Utilization Radiation Center nuclear instrumentation receives intensive use in both teaching and research applications. 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 located at the Center and instrumentation may be made available on a loan basis to OSU researchers in other departments.

C. Radioisotope Irradiation Sources

1. Description The Radiation Center is equipped with a 1,644 curie (as of 7/27/01) Gammacell 220 60Co irradiatorwhichis capable of delivering high doses ofgammaradiation over arange ofdoserates to a variety of materials.

Facilities III -3 il..

Typically, the irradiator is used by researchers wishing to perform mutation and other biological l effects studies; studies in the area of radiation chemistry; dosimeter testing; sterilization of food materials, soils, sediments, biological specimen, and other media; gamma radiation dlamage studies; and other such applications. In addition to the "0Co 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. l

2. Utilization During this reporting period there was a diverse group of projects using the 'Co irradiator. These projects included the irradiation of a variety of biological materials including different types of I

seeds. In addition, the irradiator wvas used for sterilization of several media and the evaluation of I the radiation effects on different materials. Table III.C. I provides use data for the Gammacell 220 irradiator. l D. Laboratories and Classrooms l

1. Description 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 l 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 measurement ofmanytypes ofradiation. TheCenteralso has four studentcomputerrooms l 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 specialized equipment are regularly used for teaching. In particular, classes are routinely given access to gamma spectrometry equipment located in Center laboratories. A number ofclasses also regularly use the OSTRand the Reactor Bay as an integralpartoftheirinstructionalcoursework. There are two classrooms in the Radiation Center which are capable ofholding about 35 and 18 I students, respectively. In addition, thereare two smallerconferencerooms and alibrarythat are 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 member to accommodate Facilities III -4

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 electrical 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).

2. Utilization All of the laboratories and classrooms are used extensively during the academic year. For example, a listing of courses accommodated at the Radiation Centerduring this reporting period along with their enrollments is given in Table III.D.l.

E. Instrument Repair and Calibration Facility

1. Description The RadiationCenterhas a facility for the repairand calibrationofessentiallyalltypes of radiation monitoring instrumentation. This includes instruments for the detection and measurement ofalpha, beta, gamma, and neutron radiation. It encompasses both high range instruments for measuring intense radiation fields and low range instruments used to measure environmental levels of radioactivity.

2. Utilization The Center's instrumentrepair andcalibrationfacilityis usedregularlythroughout 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 calibration of essentiallyall radiation detection instruments used by state andfederal agencies in the state of Oregon.

This includes instruments 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 OregonDepartment of Energy, the OregonPublic Utilities Commission, the Oregon Health Sciences University, the Army Corps of Engineers, and the U. S. Environmental Protection Agency. Facilities Ill -5

F. Library I

1. Description I

The Radiation Center has a library containing significant collections of texts, rescarch reports, and videotapes relating to nuclear science, nuclear engineering, and radiation protection. 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. l Department of Energy, the U. S. Nuclear Regulatory Commission, and other federal agencies. Therefore, the Center library maintains a current collection of leading nuclear research and regulatory documentation. In addition, the Centerhas acollection of a number of nuclear power reactor Safety Analysis Reports and Environmental Reports specifically prepared by utilities for their facilities. l The Center maintains an up-to-date set of reports from such organizations as the International Commission on Radiological Protection, the National Council on Radiation Protection and l Measurements, and the International Commission on Radiological Units. Sets of I he 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 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 radiological emergency response topics. In addition, the Radiation Center uses videotapes for most of the technical orientations which are required for personnel working l with radiation and radioactive materials. These tapes are produced, recorded, and edited by Radiation Center staff, using the Center's videotape equipment and the facilities of the OSU Communication Media Center.

2. Utilization The Radiation Center library is used mainly to provide reference material on an as-needed basis.

It receives extensive use during the academic year. In addition, the orientation videotapes are used l intensively during the beginning of each term and periodically thereafter. Facilities III -6 I

Part IV Reactor

Part IV REACTOR A. Operating Status Reactor power generation for the operating period between July 1, 2003 and June 30, 2004 totaled 966 kWH ofthermal power. This is equal to 40.2 megawatt days ofgeneration, and results in a cumulative thermal energy output by the OSTR FLIP core of 1068 MWD from August 1976 through June 30, 2004. The OregonStateTRIGAReactor(OSTR) operated with someinterruptions during the2003/4 reporting period. Reactor operations were suspended for a total of 5 days due to equipment failures and an abnormal core configuration created by the removal ofa fuel element in preparation for control rod calibrations. An additional 43 operating days were lost due to the construction of the neutron radiography facility adjacent to Beam Port #3 The productivity of the reactor irradiation facilities is based on reactor operation in relation to use categories. Greater productivity is achievedbyutilizing greater numbers 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 operatinghours. Critical reactor operation averaged 45.3% of each day. Of the 2160 total available annual operating hours,977 hours were at power,458 hours were spent conducting facility startup and shutdown operations, 614 hours were expended for maintenance and sample decay delays and Ill hours the reactor was not operating for reasons other than listed above. Table IV.A.1 provides informationrelated to the OSTR annualenergyproduction, fuel usage and use requests. Table IV.A.2 summarizes statistics for the original 20% enriched fuel loading. B.

Unplanned Shutdowns There were seven unplanned reactor shutdowns during the current reporting period. A scram occurs when the controlrods drop in as aresult ofan automatic trip or as aresultoftheoperator pushingthe manual trip button. Due to unusualconditions oroperational anomalies ofa less critical nature, the reactor mayalso be secured by manual rod insertion. Table JV.C. I contains asummary of the unplanned scrams, including a brief description of the cause of each. D. Changes to the OSTR Facility, to Reactor Procedures, and to Reactor Experiments Performed Pursuant to 10 CFR 50.59 The information contained in this section of the report provides a summary of the changes performed during the reporting period under the provisions of 10 CFR 50.59. For each itemnlisted, there is abriefdescription of the action taken and a summary of the applicable safety evaluation.

1.

10 CFR 50.59 Changes to the Reactor Facility There were six changes to the reactor facility during this reporting period. For additional information regarding these changes, or copies of the changes, contact the OSTR Operations staff. (1) 03-03, Removal of Existing Beam Port #3 Radiography Blockhouse (a) Description. The interim concrete block shield structure, constructed to test the beam quality and thermal neutron flux within Beam Port #3 was removed following the completion of testing and evaluation. All components of the original BP were returned to their original configuration. Reactor IV - 3

(b) Safety Evaluation Restorationofthebeampoll and its internal components returncd the facility to its original approved configuration. 1 (2) 04-04, Beanm Port #3 Collimator l (a) Description In preparation for construction ofthe permanent Beam Port #3 shield blockhouse, a neutron beam collimator was installed in BP3 in place of the original concrete and wood shield plugs. Additional lead and concrete blocks were placed in front I ofthe collimator to ensure dose rates were minimized. Reactor operations were suspended during the construction phase of the shield blockhouse. l (b) Safety Evaluation The collimatorplaced withinthe BP3 tube is external to the reactor and performrLs a passive function. The reduction of shielding capablity from the original components was offset by maintaining reactor power at shutdown levels and the l use of temporary shielding materials. (3) 04-05, Interim Configuration of the Neutron Radiography Facility (NVRF) l (a) Description l An operating configuration was placed in effect which ensured that the newly constructed NRF adjacent to Beam Port #3 would provide adequate radiological shielding during full power reactor operations prior to full installation of the proposed NRF access interlock and control system. A mechanical, airoperated shield shutter is in place3 in front ofthe Beam Port #3 collimater inside the NRF structure. Mechanically blocking the shutter in the closed position, securing operating air and alarming the NRF doors effectively restricts access to any l potential high radiation areas during the period of reactor operations. Area radiation mnonitors relocation and an at power radiation survey verify that I existing radiation levels are maintained at acceptable levels adjacent to the NRF. (b) Safety Analysis I This configuration change maintains adequate radiological protection in the absence ofan installed and operating automatic interlock and control system-L The Reactor IV - 4 I

only interface with reactor systems will be through the use of plant annunciators, attached to door micro switches, indicating possible access to the inside of the NRF. (4) 03-07, Replacement of the Primary Tank water Level Indication System (a) Description The current reactor tank water level detection systemhas been replaced with an electronic level sensing system. Theold Styrofoamfloat and microswitch system was removed. In its place, two LED/Phototransistor probes are used to detect reactor tank water level. Both high and low water levels continue to be annunciated in the control room. The monthly testing of the level proves makes an annual system test redundant. (b) Safety Analysis Since the systemcircuitryis normally energized, failureofthe systemresults in an alarm condition. Mechanical binding of the old type floats is eliminated. (5) 03-8, Installation of an In-Coire Irradiation Tube Storage Rack (a) Description An in-core rack specifically designed to hold the three in-core irradiation tubes, which were developed to expand sample irradiation capabilities, was installed in the reactor tank. This rack, designated as the 'T" rack is configured to hold the three long irradiation tubes in an advantageous position minimizing the need for creative attachment methods. (b) Safety Analysis Concerns regarding thefailure of mounting bolts allowing the rack to lodge in the control rods and interfere with their operation were assessed as being consistent with other equipment mounted to the primary tank liner. Since all tubes are slightly buoyant, minimal stress is placed on the mounting system. (6) 03-010, Removal of Fuel Element in Grid Position F29 (a) Description Fuel element #8404 was removed from core position F29 and placed in a reactor tank side storage rack. This fuel removal was required to reduce excess core Reactor IV - 5

reactivity caused by the burn up oferbium resulting in an approach to Technical l Specification limits of shutdown margin under all core configurations. (b) Safety Analysis I Fuel element #8404 was measured as having a reactivity value of $0.23 +/- $0.01. l Althoughremovaloftheelement is expected to resultin ahigher powerdensityper element in the core, the power density will not increase above that which has already been shown to be acceptable.

2.

10 CFR 50.59 Changes to Reactor Procedures Numerous changes to procedures related to reactor operation were prompted by facility changes and the periodic review of the Reactor Operations Committee (ROC). For additional information regarding these changes, or copies of the changes, contact the OSTR Operations staff. l (1) 04-01, Revisions to OSTROP 18 1 (a) Description The major procedural change under this revision was to reconfigure the Irradiation Request forms to conform to comments by users and staff and to clarify form completion and data retention processes. l (b) Safety Evaluation l The intent of the procedure was not significantly altered. The changes simply made the intent of the irradiation request form clearer and more useable to experimenters. (2) 04-07, Revisions to OSTROP 6 and 17 l (a) Description l OSTROP 6, Administrative and Personnel Procedures, reduced the number of controlled copies of the five documents deemed necessary for distribution from nine to seven. Removed the two unnecessary recipients from the distribution list. OSTROP 17, Reactor Room Ventilation System Procedures, changes were made l to clarify the location and operational steps of the reactor room ventilation system following system upgrade. Reactor IV - 6 I

(b) Safety Evaluation Procedural changes did not affect the intent, but rather updated the procedures to reflect current facility operations..

3.

10 CFR 50.59 Changes to Reactor Experiments (5) 03-05, Creation of Experiment B-33 (a) Description A new reactor experiment was created to cover the irradiation of combustible liquids in the rotating rack irradiation facility. Although this process is similar to a previous experiment, B-30, Irradiation of Jet, Diesel and Furnace Fuels, the previous experiment was retired due to lack of usage. Also, changes in the method of encapsulation were imposed. Several limitations were placed on the irradiation of combustible materials to minimize the oxygen present in the containment capsule, sample volume, flash point and internal pressure developed. (b) Safety Analysis Minimizing the potential for release of irradiated material within the rotating rack was addressed by the imposition of material limitations. E. Surveillance and Maintenance

Part 1V PROTECTION A. Introduction This section ofthereport deals with the radiation protection program at the OSU Radiation Center. The purpose of this program is to ensure the safe use of radiation and radioactive material in the Center's teaching, research, and service activities, and in a similar manner to ensure the fulfillment of all regulatory requirements ofthe 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 11.F). Assistance is also providedby thereactoroperations 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 NuclearRegulatory Commission (NRC) FacilityLicenseNo. R-106 (Docket No. 50-243) and the Technical Specifications contained in that license. The material has also been prepared in compliance with Oregon Office 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 ofradioactivity to the unrestricted environment and all exposures to radiation and radioactive materials at levels which are consistently "as low as reasonably achievable" (ALARA). B. Environmental Releases The annualreporting requirements in the OSTRTechnical 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 andtransferred are discussedbrieflybelow. Dataregarding these effluents are also summarized in detail in the designated tables. Protection V-I

Liquid Effluents Released l 'I. Liquid Efflucnts Released Il Oregon State University has implemented a policy to reduce the volume of radioactive liquid effluents to an absolute minimum. For example, water used l 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, Iiquids are always analyzed foriradioactivitybefore the holdup tank is discharged into the unrestricted area (the sanitary sewer system). For this reporting period, the Radiation Center and reactor made one liquid effluent release to the sanitary sewer. All Radiation Center and reactor facility l liquid effluent data pertaining to this release are contained in Table V.B. L.a.

b.

Liquid Waste Generated and Transferred l Liquid waste generated from glasswarc and laboratoryexperiments 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.

2.

Airborne Effluents Released I Airborne effluents arediscussed in terms ofthe gaseouscomponent and the particulate component.

a.

Gaseous Effluents I 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 I operations. It is normal for the reactor facility stack effluent monitor to begin operation as one of the first systems in the morning and to cease operation as one l ofthe last systems at theend ofthe day. All gaseous effluent data for this reporting period are summarized in Table V.B.2. Protection V - 2 I

b.

Particulate Effluents Particulate effluents from the reactor facility are also monitored by the reactor facility stack effluent monitor. Evaluation of the detectable particulate radioactivity in the stack effluent confirmed its origin as naturally-occurring radon daughter products, within a range of approximately 3 x 10 P1 iLCi/ml to I x 1 O' ItCi/ml. This particulate radioactivity is predominantly 2I 4Pb and 21 4Bi, which is not associated with reactoroperations. There was no release ofparticulate effluents with a half life greater than eight days and therefore the reporting ofthe average concentration of radioactive particulates with half lives greater than eight days is not applicable.

3.

Solid Waste Released 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 the OSU Radiation Safety Office. 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. Solidradioactive waste is disposed ofby the University Radiation Safety Officebytransfer to the University's radioactive waste disposal vendor, Thomas Gray Associates, Inc., for burial at its installation located near Richland, Washington. C. Personnel Doses The OSTR annual reporting requirements specify that the licensee shall present a summary ofthe radiation exposurereceivedbyfacilitypersonnel and visitors. For thepurposes ofthis report, the summary includes all Radiation Center personnel Nvho mayhave received exposure to radiation. These personnelhavebeencategorizedinto six groups: facility operating personnel, key facility research personnel, facilities services maintenance personnel, students in laboratory classes, police and security personnel, and visitors. 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 perform research using the reactor, reactor-activated materials, or using other research Protection V-3

a-facilities present at the Centelr. The individual dosimetry requirements for these personnel will vary l with tle type ofresearch being conducted, but vill gencrally include a quartcrly TLD film badge and TLD (finger) extremity (losimiieter-s. lfthe possibility ofneutrion eCxposuir Cexists, researchers are also monitore(1 with a track-etch/albedo neutron dosimeter. Facilities Services maintenance personnel are normally issued a gamma sensitive electronic l dosimeter as their basic monitoring device. A few Facilities Services personnel who routinely performn maintenance on mechanical or refrigeration equipment are issued a quarterly Xp(y) TLD badge and other dosimeters as appropriate for the work being performed. Students attending laboratory classes are issued quarterly XP(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 aone-time laboratorydemonstrationanddo not l handle radioactive materials are usually issued a gamma sensitive electronic dosibm-eter. These results are not included with the laboratory class students. OSU police and security personnel are issued a quarterly XP(y) TLD badge to be used during their patrols of the Radiation Center and reactor facility. I Visitors, depending on the locations visited, may be issued a gamma sensitive electronic dosimeters. OS U Radiation Centel policy does not normally allow people in the visitor category to become I 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 inl Table V.C. 1. There were no personnel radiation exposures in excess of the limit s in 10 CFR 20 or state of Oregon regulations during the reporting period. D. Facility Survey Data The OSTR Technical Specifications require an annual summary of the radiation levels and levels of contamination observed during routine surveys performed at the facility. The Center's l comprehensive area radiation monitoring programrencompasses the Radiation Center as well as the OSTR, and therefore monitoring results for both facilities are reported. Protection V - 4 I

1.

Area Radiation Dosimeters 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 equivalentrecorded on the various reactor facilitydosimeters 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 MRC (Monitor Radiation Center) designator show the room number or location.

2.

Routine Radiation and Contamination Surveys The Center's program for routine radiation and contamination surveys consists of daily, weekly, and monthly measurements throughout theTRIGAreactor facility and Radiation .Center. The frequency ofthese surveys is based on the nature of the radiation work being carried out at aparticularlocation oronother 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 program is to assure frequent on-the-spot personal observations (along with recorded data), which willprovide 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.D.3. Protection V - 5

E. Environmental Survey Data I The annual reporting requirements of the OSTR Technical Specifications include "an annual summrnary of environmental surveys performed outside the facility." I. Gamma Radiation Monitoring I

a.

On-sitc Monlitorincg 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 V.B.2 and nine environmiiiental monitoring stations. These I stations consist ofa polyethylene bottle placedinside a PVC tube attached to the reactor building perimeter fence at a height of four feet. I Each fence environmental station is equipped with an OSU supplied and processedTLD area monitor(normallythree Harshaw 7LiFTLI)-700chips per 7Li monitor in a plastic "LEGO" mount). These monitors are exchanged and processed quarterly. The total numberofTLD samples for theireporting period was 108 (9 stations x 3 chips per station per quarter x 4 quarters per year). A summary of this TLD data is shown in Table V.E. 1. During this reporting period, each fenceenvironmental station utili7ed an LIFTLD monitoring packet supplied and processedby ICN Worldwide Do simetry Service (ICN), Costa Mesa, California. Each ICN packet contained three LIFTLDs 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 ICN TLD samples for the reporting period was 90. A summary of the ICN TLD data is also shown in Table V.E. 1. Monthly measurements of the direct gamma dose rate (tirem h-) were also made l at each fence monitoring station. These measurements were made with a Bicron micro-rem per hour survey meter containing a 1" x 1" Nal detector. A total of 108 [lrem hI' measurements were taken (9 stations per month x 12 months per year). The total calculated dose equivalent was determined by l averaging the 12 separate [trern h-' measurements and multiplying this average by 8760 hours per year. A summary of this data is shown in Table V.E. 1. From Table V.E. I it is concluded that the doses recorded by the dosimeters onl the TRIGA facility fence can be attributed to natural background radiation, which is about 110 mrem per year for Oregon (Refs. 1, 2). Protection V - 6 I

b.

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. Eachoff-siteradiationmonitoring station is equipped with an OSU-supplied and processed TLD monitor. Each monitor consists ofthree Harshaw 7LiFTLD-700 chips in a plastic "LEGO" mount. The mount is placed in a polyethylene bottle inside a PVC tube which is attached to the station's post 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 of TLD samples during the current one-yearreporting period was 240 (20 stations x 3 chips per stationperquarterx4 quarters per year). A summaryofthe OSU off-siteTLD data is provided in Table V.E.2. The total number of ICN TLD samples for the reportingperiod was 144(12 station x 3 TLDs per stationx4 quarters). The total number of ICN TLD samples for the reporting period was 128. A summary of ICN TLD data for the off-site monitoring stations is also given in Table V.E.2. In a manner similar to that described for the on-site fence stations, monthly measurements of the direct gamma exposure rate in microremperhour ([remh-1) are made at each of the twenty off-site radiation monitoring stations. As noted before, these measurements are made with a Bicron micro-remper hour survey meter containing a I " x I " Nal detector. A total of 240 jIremh-1 measurements were made during the reporting period (21 stations per month x 12 months per year). Thetotaldose equivalentforeach station was determinedby averaging the 12 separate jiremIlf measurements andmultiplyingthis averageby8760hours per year. A summary of these data is given in Table V.E.2. After areview ofthe data inTable V.E.2, it is concluded that, like the dosimeters on the TRIGA facility fence, all ofthe doses recorded by the off-site dosimeters canbe attributed to naturalbackgroundradiation, whichis about 110 mremper 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 quarterly basis. The program monitors highly urnikely 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 Protection V-7

locations of the sampling stations for grass (G), soil (S), water(W) and rainwater(RW) l samples. Most locations arc wvithin 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 quarterly sampling locations: four soil locations, four water l locations (when water is available), and fourteen vegetation locations. The total number of samples taken during this repollinggperio( is 86(16 soil samples. 14 waler samples, and 56 vegetation samples). The annual average concentration oftotal net beta radioactivity (minus tritium) forsamples 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 background from the gross beta l counting rate, followed by application of an appropriate counting system efficiency. The annual average concentrations were calculated using sample results which exceeded l 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 concentration. Table V. E.4 gives the averge LLD concentration and the range of LLD values for each sample category for l 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 [iCi per unit volume or unit mass) in a representative sample, which has a 95% probability of being detected. l Identification o f 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, fromTable V.E.3 itcan be seen that the levels ofradioactivity detected were consistent with naturally occurring radioactivity and comparable to values reported in previous years. F. Radioactive Material Shipments A summary of the radioactive material shipments originating from the TRIGA reactor facility, NRC l license R-106, is shown in Table V.F. 1. 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. A summary of radioactive material shipments exported under Nuclear Regulatory Commission general license 10 CFR 110.23 is shown in Table V.F.3. I Protection V - 8 I

Part VI Work

Part VI WORK A. Summary The Radiation Center offers a wide variety of resources for teaching, research, and service related to radiation and radioactive materials. Some ofthese are discussed indetailin other parts ofthis report. The purpose of this part is to summarize the teaching, research, and service efforts carried out during the current reporting period. B. Teaching An important responsibility ofthe Radiation Center and the reactor is to support OSU's academic programs. Implementation of this support occurs through direct involvement ofthe Center's staff and facilities in the teaching programs of vanous departments and through participation in University research programs. Tables III.A.1 and IlI.D.l plus Section VI.C.5 provide more detailed information on the use of the Radiation Center and reactor for instruction and training. C. Research and Service Almost all Radiation Center research and service work is tracked by means ofa 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 involved, a description of the project, Radiation Center resources needed, the Radiation Center project manager, status of individual runs, billing information, and the funding source. Table VI.C. 1 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. Details on graduate student research which used the Radiation Center are given in Table VI.C.2. The major table in this section is Table VI.C.3. 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 VI also highlights major Radiation Center capabilities in Work VI - I

I a-research and service. These unique Center functions are described in Sections VI.C. 1 through L VI.C.8.

1.

Neutron Activation Analysis I Neutron activation analysis (NAA) stands at the forefront of techniques 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 nuclearreactor such as the OSTR to produce specific radionuclides. After the irradiation, the characteristic gamma rays emitted by the decaying radionuclides are quantitatively measured by suitable semiconductorradiation detectors, and the gamma rays detected at a particular energy are usually indicative ofa specific radionucide's presence. Computerized data reduction of [ the gamma ray spectra then yields the concentrations ofthe various elements in samples being studied. With sequential instrumental NAA it is possible to measure quantitatively l about 35 elements in small samples (5 to 100 mg), and for activable elements the lower limit of detection is on the orderofparts per million or parts perbillion, 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 spectrum of material types and involving virtually every scientific and technical field. While some researchers performtheir own sample counting on their own oron Radiation Center equipment, the Radiation Center provides a complete NAA service for researchers and others who may require it. This 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 l in Table VI.C.3.

2.

Forensic Studies I Neutron activation analysis can also be advantageously used in criminal investigations. The J principle underlying such application usually involves matching trace element profiles in objects or substances by NAA. 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 l materials recovered from a victim to similar materials obtained from suspects. Materials which have been analyzed by the RadiationCenterfor forensic purposes include bullets, metals, paint, fuses, coats, glass, meat, and salts. I Forensic studies performed in this reporting period are included in the listings in Tables VI.C. 1 and VI.C.3. Work VI - 2

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.

4.

Radiological Emergency Response Services The RadiationCenterhas anemergencyresponseteamcapable of responding to all types of radiological accidents. This teamdirectly supports the City of Corvallis and Benton County emergency response organizations and medical facilities. The team can also provide assistance at the scene of anyradiological 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 instrumentation. These items are located at the Radiation Center and at the Good Samaritan Hospital; During the current reporting period, the Radiation Center emergency response team conducted several training sessions and exercises, but was not required to respond to any actual incidents.

5.

Training and Instruction In addition to the academic laboratory classes and courses discussed in Parts III.A.2, III.D, and Vl.B, and in addition to the routine training needed to meet the requirements of the OSTREmergencyResponse Plan, Physical SecurityPlan, and operatorrequalification prograrn, 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 reactor radiation protection, radiological emergency response, reactor behavior (for nuclearpowerplant operators), neutronactivationanalysis, 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; orindividualreactor operator orhealthphysics training programs. During this reporting period there were a large number of such people as shown in Part II.B. Work VI - 3

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.

6.

Radiation Protection Services The primary purpose of the radiation protection program at the Radiation Center is to l support the instruction and research conducted at the Center. However, due to the high quality of the program and the level ofexpertise and equipment available, the Radiation l 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 health physics services which are not readily available l 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 ofproviding health physics services in any of the areas which are discussed in Part V. These include personnel monitoring, radiation surveys, l sealed source leak testing, packaging and shipment ofradioactive materials, calibration and repair of radiation monitoring instruments (discussed in detail in Section VI.C.7), radioactive waste disposal, radioactive material hood flow surveys, and radiation safety l analysis and audits. The Radiation Center also provides services and technical support as a radiation l laboratory to the State of Oregon Radiation Protection Services (RPS) in the event of a radiologicalemergencywithinthe state ofOregon. In this role, the Radiation Centerwill provide gammaray 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-l institution drills.

7.

Radiological Instrument Repair and Calibration l While repairof nuclearinstrumentationis apracticalnecessity, routinecalibrationofthese instruments is alicensingandregulatoryrequirementwhichmustbemet. As aresult, the Radiation Center operates a radiation instrument repair and calibration facility which can accommodate a wide variety of equipment. l 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 is therefore minimized. Work VI - 4 l1

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 ofalpha, beta, gamma, and neutron radiation, as well as instruments designed forlow-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 instructional and research programs and the OSTR Emergency Plan, while Table VI.C.5 shows instruments calibrated for other OSU departments and non-OSU agencies.

8.

Consultation Radiation Center staff are available to provide consultation services 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 researchers encountering problems or planning the design of experiments. 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.

9.

Public Relations The continued interest of the general public in the OSTR is evident by the number of people who have toured the facility. given during this reporting period. SeeTable VI.F. 1 for statistics on scheduled visitors. 'Work VI - 5
