I I. INT RODUCT ION The Nuclear Science Center is operated by the Texas Engineering Experiment Station as a service to the Texas A&M University System and the State of Texas. The Nuclear Science Center provides services to researchers and/or faculty from Texas A&M University, other colleges I and universities, government agencies and private industry. The Nuclear Science Center is recognized primarily for providing radio-isotopes and other nuclear irradiation services for research, I academic, medical and industrial applications and as a teaching and nuclear training facility. The facility operating license, B-83 hr ugh a h, 2 b3 This report has been prepared by the staff of the Nuclear Science Center of the Texas Engineering Experiment Station to satisfy the I reporting requirements of Technical Specification 6.6.1 t-o the facility operating license R-83 and of U.S. DOE Contract

  1. DE-AC05-76ER04207 ( formerly E Y-7 6-C-05-4 207 ) and 10CFR50 59 The I report covers the period from January 1, 1990 through December 31, 1990.

~

al operating hours of the reactor increased over 1989 values.

The total experiment hours were much higher than 1989 with an increase in sample irradiation hours. Irradiation experiments continued to increase and there was a decrease in irradiation cell and beam port I experiment hours compared to 1989 Bear port utilization was down due to the unavailability of the beam ports during upgrades that were being performed. Commerciel utilization and the number of tours decreased slightly.

Core VIII-A, which has been operational since March 1986, was used throughout 1990. Pulse operations were continued at a low level I in 1990 with a total of 30 pulses ($43 15 total pulse reactivity) executed. As in the prev 1ous .few years , pulsing operations were per-formed mostly for calibrations and laboratory demonstrations.

There were no changes made to the site area curing this reporting period and no changes were made to the security or emergency plans.

A license change to R-83 was approved this year which modifies the NSCR line management structure. The NSC Radiation Protection Office now -eports directly to the Deputy Director of TEES and works in cooperation with the NSC staff.

l A. Utilization Summary Utilization of the NSCR for the 1990 calendar year is illustrated by Figure I and Table I. Figure I shows the annual I totals for reactor operation for the years 1975 through 1990.

During the present rer.-ting period the NSCR was utilized by over -

400 students (including 17 researchers) and 32 faculty and staff l l members representing 15 departments at Texas A&M University. In i addition, more than 180 faculty and students from 15 other edu-

' cational institutions used the facilities and 2,998 visitors were registered during 1990. A total of 17 non-educational organi-zations utilized the NSCR during the year for their commercial l and research applications.

I 14 III. REACTOR AND FACILITY OPERATIONS l A. Changes Pursuant to the Recuirements of 10CFR50.59 In accordance with the requirements of 10CFR50.59, changes to the facility and procedures and changes in the conduct of tests and experiments that occurred during the reporting period were reviewed and documented It was concluded that these changes do not constitute a change in the Technical Specifications, do not present an unreviewed I safety question, and do not increase the probability of an accident previously analyzed in the NSCR Safety Analysis Report. It was concluded that these changes do not increase the possibility that an I accident or malfunction of a different type than any evaluated previously will be created, and do not reduce the margin of safety as definec in the bases for any Technical Specification.

1. Chances to the Reactor Svstems Shir Safety Potentiometer Replacement The coarse incremental adjustment of the existing potentiometers that control the amount of current to the shim safety control rod I electro-magnets made it difficult to set desired current levels.

Also, a special purchase order had to be made anytime it was necessary to replace the potentiometers. Therefore, the potentiometers were re-( I placed with locally available potentiometers that uw a multi-turn adjustment and have the same milliamp adjustment range, ohm rating, and mounting structure as the old potentiometers.

2. Changes to Experimental Facilities Real-Time Radiograohy Capabilities with Beam Port 4 Dr. Jon Reuscher, Professor, and Director, Nuclear Research Reactor Pragt ams , designed and implemented a real-time radiography Changes were made to the Beam Port 4 cave I program for the facility.

to allow access for the handling of radiographed samples. The cave now has a movable shield block which covers an access opening on top of the cave. The Beam Port water shutter control circuitry provides I an interlock to flood the shutter if the shield block is moved from its closed position during beam port operations. A "C-2" high radiation area personnel access monitoring system was installed at the l shield block cave opening. This system is activated when the shield block is not in its closed position. Several different objects have been successfal2y radiographed in the cave with no adverse radio-logical consequences.

I 15 I

Changes to the Thermal Column Shielding The Poretics take-up spool box is now shielded by a moJable shield fabricated of steel plates and having a leaded glass windvw to allow I viewing of the take-up roll. The existing shield blocks, Thermal Column Door, and foncing were extended to provide room for movement of the take-up spool box shield. Use of the movable shield has reduced personnel radiation exposures.

Beam Pc 1 Safety Improvements An interlock for the Beam Port 1 water shutter was added to the Beam Port 1 area entry gate. If the gate is opened during beam port operation, the water shutter will flood. Flooding of the water I shutter provides additional protection against undue personnel radiation exposures.

3. Chances to the NSC Facility Addition of a Volume Meter to the Liquid Waste Holdup Tanks A volume meter has been added to the raw water supply line to the liquid holdup tanks. This was added to more accurately determine dilution to the radioactive liquid waste released to White Creek.

I Past reported radicactivity release concentration levels have been conservative without this information. The meter therefore enables the NSC to improve the accuracy of reporting liquid waste release concentrations.

Reactor 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 I Log Power Channel High Power (Safety) Channels Facility Air Monitoring Channels I Area Radiation Monitoring Channels All control rods were calibrated during annual maintenance 2.

I performed in January, 1990 with a total rod worth of

$16 32 and a shutdown margin of $2.68.

l 3 The power level (linear) channel was calibrated by the calorimetric method on 1/8/90.

4 The rod scram time checks resulted in times less than the Technical Specification limit of 1.2 seconds.

5 Fuel elements requiring inspection were inspected by 8 January 1990.

6. The pulse measuring channel was calibrated on 2/1/90.

Pulse operation parameters are verified semi-annually by l

I pulsing the reactor for comparison of pulse energy and fuel temperature to previous pulse operation values.

l The maximum allowable pulse reactivity insertion is $2.09 for Core VIII-A as determined by a pulse test program. An administrative limit of $1.90 is imposed for pulse operations.

I 7 The reactivity worth for each experiment was measured or I estimated as appropriate before performance of the experiment. The most reactive fixed experiment is the Thermal Column coupler with a value of $1 35

8. The annual facility evacuation drill and staf f emergency response was conducted on 4/9/90.

9 A review of the NSC security plan and emergency plan was conducted by the NSC staff prior to the Reactor Safety Board review conducted on 2/19/90.

10. A review of the NSC ALARA program was conducted by the NSC staff prior to the Reactor Safety Board review conducted on 2/19/90.

All other required maintenance as set forth in the Technical E Specifications was perrormed annually, semi-annually, or weekly as E required. This was in addition to completion of a pre-startup check-list done daily prior to reactor operation, and other daily checks.

C. Unscheduled Reactor Shutdowns A total of thirteen unscheduled shutdowns occurred during 1990.

The unscheduled shutdowns were caused by the following:

Six shutdowns caused by a complete power failure to the facility.

One shatdown when Shim Safety #4 inadvertantly dropped when approaching 1 MW power. No reactor scram signals were received, One shutdown initiated due to Shim Safety #4 dropping when magnet i

l current drifted low.

l One shutdown due to a sample upon removal being passed near the Safety Channel #1 detector. The high gamma level of the sample produced a high reading on the Safety Channel #1 detector. The sample removal was performed following a reduction in reactor I power of 40% as required.

One shutdown due to a short to ground in the Beam Port #4 cave l

door interlock circuitry. This occured during installation of

) the Beam Port Cave top shield door circuitry and with the reactor outside the beam port / thermal column rail stop.

One manual shutdown was initiated by action of the SRO when an i object was accidently dropped into the pool near the reactor I

g frame and having the potential to settle on top of the reactor g core. The object did not strike the core and came to rest on the bottom of the pool.

I I Effluent Release Summary Introduction Summaries of the radioactive effluents releases from the Nuclear Science Center for 1990 are included in this Appendix.

These data are presented in tabular form and includes atmospheric, liquid and solid waste releases.

Particulate Releases I Radioactive particulate are monitored at the base of the central exhaust stack and are summarized on a monthly basis. The annual average release rate was 8.46 E-11 uCi/cc. Total activity release for 1990 was 6.26 E-3 C1.

Gaseous Releases I 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 release during 1990 was 7.11 Curies. This figure yields an annual release rate of 9.62 E-8 uCi/cc as measured in the central exhaust stack with no dilution factors applied. These data are summarized in Table 2.

I Solid Radioactive Waste Approximately 104.2 kg of uncompacted dry solid waste I material was packaged in plastic bags for disposal during 1990.

These materials were transferred to the Texas A&M University.

Office of Radiological Safety, Texas License No. 6-448 for disposal. These plastic bags contained laboratory glassware, irradiation containers, decontamination materials, and expendible protective clothing (shoe covers, gloves). The total I radioactivity in all these bags summed was 4.7 E-2 Ci.

is shown in Table 3.

This data The Radiation Protection Staff also transferred several I barrels of waste resins to the Texas A&M University Office of Radiological Safety. The total activity in these barrela of waste resins was 1.33 E-2 C1. This data is shown in Table 3A.

I I Liquid Waste Releases I Radioactive liquid effluents are collected in liquid holdup waste tanks prior to release from the confines of the Nuclear Science Center. Sample activity concentrations and isotope identification was performed for each release. There were 41 I releases in 1990 totaling 1.47 E+6 liters excluding dilutents from the Nuclear Science Center. The total radioactivity released for 1990 was 1.28 E-2 Ci with an average concentration I of 2.96 E-5 uCi/cc. Summaries of the radioisotopic data are presented in Tables 4 through 16. Radioactivity concentrations for each isotope were below the limits specified in 10 CFR20, Appendix B Table II, Column 2.

V-21 ENVIRONMENTAL SURVEY PROGRAM 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 identificati3n. Data from these samples reflect the continued use of retention facilities and sample analysis for laboratory effluents prior ',:o their I release.

The environmental survey program includes the in-s..tu I measurement of integrated radiation exposures at th.* sice boundaries. These measurements are made for a period of approximately 90 days using flouride clips in glass et.capsulated bulbs. The dosimeters are provided and processed by 'taxas Department of Health, Bureau of Radiation Control, Di /iaion of Environmental Programs. The state utilizes a backgrotnd monitor located at a point 5.25 miles west-southwest of the N!ic f tcility.

This site for the background measurement is generally at right angles to the prevailing southeasterly winds.

Table 17 lists the average exposure rate above ambitnt background for a number of locations at the site boundary. The highest exposure point was determined to be at Site #12 (349 mR/yr) which is on the NSC Site Boundary fence northeast of the I reactor building near the calibration range source building.

The closest offsite point of extended occupancy is .' 6-ated I just beyond the Site Boundary fence directly behind the Si':e #10 monitoring locntion. From the data in Table 17, it can De easily shown that those occupants received much less than twice the average local off-site background exposure.

Summaries of the environmental curvey program for 1990 are presented in Tables 18-21 for total (sum) gamma or total beta activity as reported to the NSC or as determined by the NSC when data from the state was unavailable.

I RADIATIO!4 A!4D CO!1TAMI!1ATIO!1 CO!1 TROL PROGRAM Introduction I The detection and elimination or control of radiation hazards is an integral part of the Radiation Safety program at the 11uclear Science Center. The radiation and smear survey I programs contribute to the control and climination of these health hazards. This program is effective in preventing the spread of radioactive contamination, improper storage of radioactive materials, and unwarranted exposures.

Radiation Survey I The 11uclear Science Center uses an area radiation monitoring system consisting of ten (10) detector channels located throughout the Reactor and Laboratory Buildings. This system is equipped with alarm settings and remote readouts jn the control I and reception roors. Radiation icvels 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 I Nuclear Science Center facilities and site boundaries are surveyed monthly with beta-gamma sensitive instruments. These measurements are taken to determine proper storage and I 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 I 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 1990.

S Contamination Survqy I The Nuclear Science Center is routinely surveyed for radioactive contamination overy month. This program includes the collection, analysis and evaluation of approximately 200 smear samples and the decontamination of areas and materials with I removable beta-gamma radioactivitics of greater than 250 dpm/100 cm2 . The 250 dpm/100 cm2 is an administrative limit, Standard Operating Procedures call for decantamination of any items with levels in excess of 1000 dpm/100 cm . 2 I

V-27 I

PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science

l Center in 1990 were below the limits set forth in 10CTR20.101.
E The maximum exposure received by any individual for the year was 460 mrem. A total of 3.6 MANREM was received for 1990. These data are summarized in Table 22.

All employees at the Nuclear Science Center were changed to neutron badges as an evaluation of the potential for exposure to neutrons indicated that the majority of NSC employees have the potential for exposure.

I lE During 19:0, 2,998 persons visited the Nuclear Science iE Center. The mtaximum exposure to any visitor as determined by issued film badges did not exceed minimum measurable quantities.

Dosimetry results were provided by a NVLAP accredited supplier.
