s 1 J F I. INTRODUCTION The Nuclear Science Center is operated by the Texas Engineering' Experiment Station as a service to the Texas A&M University System and The facility is available to the University, 83 the State of Texas. ( organizations and individuals. The facility operating license R-issued by the U.S. Nuclear Regulatory Commiet ion, currently extends through March, 2003 ( This report has been prepared by the staff of the Nuclear Science Center of the Texas Engineering Experiment Station to satisfy the [ reporting requirements of Technical Specification 6.6.1 to-the 5 facility operating license R-83 and of U.S. DOE Contract

1. DE-AC05-76ERO)4207 (formerly EY-76-C-05-4207) and 10CFR50.59 The report covers the period from January 1,

1989 through December 31, r 1 1989. Total operating hours of the reactor increased over 1988 valuss. ( The total experiment hours were approximately the same as 1988 with a decrease in sample irradiation hours. Beam port and irradiation experiments continued to increase and there was a decrease in [ irradiation cell experiment hours compared to 1988. These changes in l utilization were due primarily to the characteristics of the experi-ments performed. Comme"cial utilization and the number of tours increased. ( Core VIII-A, which has been operational since March 1986, was used throughout 1989. Pulse operations were continued at a low level ( in 1989 with a total of 40 pulses ($61.48 total pulse reactivity) executed. As in the previous few years, pulsing operations were re-stricted mostly to calibrations and laboratory demonstrations. -f There were no changes made to the site area during this reporting period and no changes were made to the security or emergency systems..

s 2 k II. REACTOR UTILIZATION A. Utilization Summary Utilization of the NSCR for the 1989 calendar year is illustrated by Figure I and Table 1. Figure I shows the annual totals for reactor operation for the years 1975 through 1989 During the present reporting period the NSCR was utilized by over 500 students'(including 48 researchers) and 29 faculty and staff members representing 15 departments at Texas A&M University. In addition, more than 180 faculty and students from 15 other edu-cational institutions used the facilities and 3,729 visitors were registered during 1989. A total of 19 non-educational organi-zations utilized the NSCR during the year for their commercial and research applications. During twenty-eight years of operation, the NSC has provided services to 46 departments at Texas A&M University, 114 other colleges and universities, 103 industrial organizstions, and 25 governmental and medical organizations (see Appendix III and IV for listings).

s h 11 r N III. FACILITY OPERATIONS [ A. Facility Improvements ( New Facility Air Conditioning Units Two new smaller air conditioning chill water cooling units were installed as replacement of an older unit that could not be repaired. B. Improvements to Reactor Systems and Experimental Facilities { Miscellaneous Eouipment Control Drawer This drawer was completely rebuilt with new components and a new I face format. The drawer still controls the following devices: lower I research level access controls, front gate, C-2 warning devices, cell / pneumatic exhaust fan, water shutter indications, and operator status board. Facility Air Monitor Meters New FAM meters were installed as replacement of meters in the reactor control room and the reception room. The old meters were hard to find, very expensive, and difficult to calibrate. The new meters are better in all of these respects. New Switches for Reactor Console Pump switches were replaced and solid state contF/;l circuits provided for water system control. These type swit/+es have reduced electronic noise sources considerably. As a result, there have been fewer spurious signals to the reactor instrumentation. A heavy duty reactor console power switch was installed as a replacement to improve reliability. Diffuser Pump and Transient Rod Eurge Tank Blowdown Piping Rearrangement The diffuser pump piping and transient rod tiowdown piping were rearranged under the reactor bridge to make room for the new east face irradiator. Additional Rotisserie Irradiation Device Storage To expand the capacity of rotisserie storage a new rack was installed on the north pool wall. The rack has storage positions for 12 rotisserie irradiation devices.

12 I Additional Sump Pump Strainer and Blow Down ( A new strainer and strainer blowdown piping were installed parallel to the old sump pump strainer and blowdown. These strainers prevent solids from reaching the liquid waste holdup tanks. The blowdown piping enables the strainers to be cleaned periodically. Self Adjusting Skimmer Hcad ( The old skimmer heads would not work well with different pool levels due to the difficulty in adjusting their heights. A new single skimmer nead was designed to be self-adjusting and is working fine. Cross-Connect Valves in the Facility Air Monitoring System r New valves for this system were added upstream of the main flow ( control panel. These valves allow a cross connect between air sampling locations and detectors. In case a detector normally required for operations is out of service, the appropriate sampling { location can be changed to another operable detector. Beam Port #1 Collimator A series of cylinders of graphite, borated parrafin, lead, boroflex, and concrete were placed inside Beam Port #1 to act as a collimator of neutrons. This creates a narrower and more con-trollable neutron beam for experiments. C. Operational Problems Reportable Occurrence 89-01 Adjustment of Linear Channel Compensating Voltage There was a requirement to adjust the linear channel compensating voltage due to a significant increase in scheduled reactor operating hours. When additional night shift operations were added, the increase in core power history caused the startup gammas to be more significant at low power levels. The compensation voltage was reset and normal readings returned. All required tests were performed and the instrument was returned to norLal operation. Beam Port #1 Water Shutter Repair A down leg of the water shutter was leaking at the union with the beam port piping. The down leg leak was repaired using a saddle at the union. A gasket was used to seal the saddle to the beam port piping. The saddle is held in place against the beam port piping with two stainless steel strapes. This design has performed well since installation.

s / 13 s ( Faf. lure of Compressed Supply Air Piping Compressed air supply piping between the demineralizer room and the tunnel area suffered a corrosion stress fracture. Galvanized piping was used for replacement which has a greater resistance against moisture corrosion than the previous used iron piping. Control Rod Drive Circuit ry Troubleshooting The control rod drive units exhibited infrequent malfunctions in withdrawal operation and position indication over the year. In each case, the circuitry was either repaired or replaced immediately and operation of the circuitry was tested to ensure it performed in accordance with all previously approved changes and modifications. D. Procedural Changes Changes to the following SOP's were reviewed and approved by the Reactor Safety Board during the reporting period: SOP's II-C Reactor Startup Figure II-C-1(c) Pre-Startup Checklist III-I Scram Circuit Surveillance III-L Control Rod Drive Maintenance Figure III-B-2(a)(b) Fuel Element Temperature Measuring Channel - Semiannual Maintenance Figure III-E-2(a)(b) Safety Power Measuring Channel - Annual Maintenance Figure III-I-2 Scram Circuit Surveillance - Semiannual Check IV-C Pneumatic System Operation IV-D Beam Port Experiments IV-F Neutron Radiography Beam Port #4 IV-H Thermal Column Film Irradiator Figure VI-B-1(a)(b) Weekly Reactor Maintenance VII-A3 Reporting Requirements VII-B4 Daily Facility Air Monitoring Check VII-B7 Area Radiation Monitors VII-B14 Personnel Dosimeters VII-C2 Radioactive Materials Released Off-Site VII-C3 Radioactive Materials Released to Campus VII-C6 Radioactive Materials Storage VII-C7 Radioactive Solid Waste Disposal VII-C14 Facility Contamination Survey VII-E1 Radiation Monitoring Devices and Exposure Control Guides VIII-D Safeguards Information l l i

N 14 E. Unscheduled Shutdowns (l A total of seven unscheduled shutdowns occurred during 1989. The unscheduled shutdowns were caused by the followingt ( One shutdown caused by equipment failure in a fail-safe mode. One shutdown caused by Safety Channel #2 instrumentation spike. ( One shutdown caused by a sticking period meter during startup. Four shutdowns due to complete power loss to the facility. [ 'There were no shutdowns due to operator error this year. F. 8eactor Maintenance and Surveillance ( 1. The Technical. Specification requirements for maintenance and surveillance were completed for all required channels as follows: ( Fuel Element Temperature Measuring Channel Linear Power Channel ( Log Power Channel High Power (Safety) Channels Facility Air Monitoring Channels Area Radiation Monitoring Channels All cor. trol rods were calibrated during annual maintenance performed in January, 1989 with a total rod worth of $15.75 and a shutdown margin of $2.73 The power level (linear) channel was calibrated by the calori-metric method on 1/5/89 The rod scram time checks resulted in times.less than the Technical Specification. limit of 1.2 seconds. Fuel elements requiring inspection were inspected by 5 January 1989 All other required maintenance as set forth.in the Technical Specifications was performed annually, semi-annually, or weekly as required. This was in addition to completion of a pre-startup checklist done daily prior to reactor operation, and other daily checks.

f. L 15 ( 2. The pulse mode is calibrated annually by comparison of flux foils. Operability is verified semi-annually by pulsing for (. comparison of pulse energy and temperature. The maximum allowable pulse reactivity insertion is 42.09 for [ Core VIII-A as determined by a pulse test program. An administrative limit of $1 90 is imposed for pulse operations. 3 The reactivity worth for each experiment was measured or ( estimated as appropriate before performance of the experiment. The most reactive fixed experiment is the Thermal Column coupler with a value of $1 35 f 4 The biennial Emergency Preparedness drill was conducted on April 20, 1989 5. A review of the NSC security plan and emergency plan' was con-ducted by the NSC staff and the Reactor Safety Board'on 2/10/89 6. A review of the NSC ALARA program was conducted by the NSC staff and the Reactor Safety Board on 2/10/89 4

I-2 l NEUTRON DEPTH PROFILE EXPERIMENT l Personnel Dr. J. A. Reuscher -- Professor N. Khalil -- Graduate Assistant i A neutron depth profile apparatus was designed, built and installed at Beam Port #1. This device uses a charged particle detector to measure the alpha particle emission from a sample B containing trace amounts of boron. The alpha particle energy spectrum l 1s used to determine the depth profile of the boron in the sample. Experimental results using the device compared exactly with data obtained by the National Institute of Standards and Technology (NIST) I on the same sample of borosilicate glass. NIST obtained data during a 15 minute beam exposure and our apparatus required 5 hours. REAL-TIME NEUTRON RADIOGRAPHY Personnel Dr. J. A. Reuscher -- Professor John Wright -- Graduate Assistant Scott Midgett -- Graduate Assistant A real-time neutron radiography system was developed and installed at Beam Port #4 This system uses a ZnS(LiF) scintillating l screen to obtain images of samples placed in the neutron beam. The B screen low-level light emission is intensified by a. relay optics unit and collected by a monochrome CCD television camera. The TV image is i g digitized at a rate of 30 frames /second by an IBM PC/AT with image l capture and processing boards. The neutron radiography image is dis-played on a high resolution CRT. Numerous image enhancement options are available using digital filtering or false color displays..The system shows good resolution for small holes (0.020-inch) in a cadmium plate or standard film quality indicators. The system is being used to image operating heat pipes, bubble flows in liquids, the melting of I metallic samples, moisture content measurements in zeolite and other research areas. I l

V-2 r EFFLUENT RELEASE

SUMMARY

L Introduction r L Summaries of radioactive effluents released from the Nuclear Science Center for 1989 are included in this Appendix. These data are ( presented in tabular form and itcludes atmospheric, liquid and solid waste releases. Particulate Releases Radioactive particulates are monitored at the base of the central exhaust stack and summarized on a monthly basis. The annual average f release rate was 1.42 E-11 pC1/cc. Total radioactivity released for the year was 1.06 E-03 Curies. These data, presented in Table 1, represent output of the Nuclear Science Center Facility Air Monitoring j System. The individual particulate monitors in this system detect gross beta and gamma radiations emitted from filtered particulate

material, f

Gaseous Releases Argon-41 is the major gaseous effluent produced and released at ( the Nuclear Science Center. This effluent is measured by counting the Argon-41 photopeak in the gaseous discharges of the central exhaust stack. Total Argon-41 released during 1989 was 2.46 Curies. This [ results in an annual average release rate of 3 98 E-07 pCi/cc as i measured in the central exhaust stack with no dilution factors applied. Applying the dilution factor of 5.0 E-03 allowed at the site boundary (as determined, SAR, pages 116-119, June 1980) results in [ radioactivity concentrations of < 5.0% of the limits specified in 10CFR20, Appendix B, Table II, Column 1. These data are summarized on a monthly basis and presented in Table 2. I l l l

V-20 ENVIRONMENTAL SURVEY PROGRAM Introduction k The environmental survey samples were collected in accordance with the schedules of the cooperative surveillance program between the { Texas State Department of Health and the Texas A&M University. These samples were analyzed for gross gamma and beta activities and isotope identification. Data from these samples reflect the continued use of [ retention facilities and sample analysis for laboratory effluents I prior to their release. The environmental survey program includes the in-situ measurement of integrated radiation expcsures at the site boundaries. These measurements are made for a per;od of approximately 90 days using commercially available thert.:oluminescent dosimeters (TLD's) of lithium fluoride chips in glass encapsulated bulbs. The dosimeters are pro-r vided and processed by Texas Department of Health, Bureau of Radiation Control, Division of Environmental Programs. The state utilizes a background monitor located at a point 5.25 miles west-southwest of the NSC facility. This site for the background measurement is generally at right angles to the prevailing southeasterly winds. Table 17 lists the average exposure rate above ambient background for a number of locations at the site boundary. The highest exposure point was determined to be at Site #3 (390 mR/yr) which is on the NSC Site Boundary fence west by south-west of the reactor building. The closest offsite point of extended occupancy is located just beyond the Site Boundary fence directly behind the Site #10 monitoring location. From the data in Table 17, it can be easily shown that those occapants received much less than twice the average local off-site background exposure. Summaries of the environmental survey program for 1989 are pre-sented in Tables 18-21 for total (sum) gamma or total beta activity as reported te the NSC or as determined by the NSC when data from the state was unavailable. ,3

The maximum exposure received by any ir dividual for the year was 440 mrem. A total of 316 MA!JRE14 was received for 1989 f During 1989, 3.745 persons visited the lauclear Science center. The maximum exposure to any visitor as determined by issued film ( badEes did not exceed minimum measurable quantities. Dosimetry results were provided by a !JVLAP accredited supplier. ( l

V-27 i L RADIATION AND CONTAMINATION CONTROL PROGRAM Introduction ( The detection and elimination or control of radiation hazards is an integral part of the Radiation Safety Program at the Nuclear { Science Center. The radiation and smear survey programs contribute to the control and elimination of these health hazards. This program is effective in preventing the spread of radiaoctive contamination, improper storage of radiaoctive materials, and unwarranted exposures to radiation. { Radiation Survey The Nuclear Science Center uses an area radiation monitoring I system consisting of ten (10) detector channels located throughout I the Reactor and Laboratory Buildings. This system is equipped with alarm settings and remote readouts in the control and reception rooms. Radiation levels and operational checks are recorded on a daily basis. This system functions as a radiation safety monitor for the early detection of radiation hazards. The Nuclear Science Center facilities and site boundaries are surveyed monthly with beta-gamma sensitive instruments. These measurements are taken to determine proper storage and identification of radioactive materials and that visitor and routine work areas are free of radiation hazards. Additionally, radiation monitoring support is provided for the reactor operations and experimenter groups to insure the safe handling of radioactive materials and control of personnel exposures. At the perimeter of the NSC site, radiation levels did not exceed the 500 mrem dose limit during 1989 Contamination Sur vey The Nuclear Science Center is routinely surveyed for radioactive contamination every month. This program includen the collection, analysis and evaluation of approximately 250 smear samples and the decontamination of areas and materials with rem able beta-gamma radioactivities of greater than 1000 dpm/100 cm
