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 State of Texas.
The facility is available to the University, other educational institutions, government agencies, and private organizations and individuals.
The facility operating license, R-83 issued by the U.S. Nuclear Regulatory Commjssion, was renewed in March, 1983 and extends through March, 2001 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 U.S. DOE Contract #DE-AC05-76ER04207 (formerly EY-76-C-05-4207) and of the U.S.
NRC, under 10CFR50.59 The report covers the period from January 1,
1987 through December 31, 1987.
Utilization of the reactor during 1987 increased slightly over that in 1986.
Although some parameters of reactor use, such as the number of irradiations and average irradiations per day decreased slightly, overall use of the reactor was greater than in 1986.
The number of irradiation experiment hours decreased significantly in 1987 but there were large increases in the hours of beam port and irradiation cell usage.
This reflects a shift in the NSC's main activity from isotope tracer production to testing and exposure irradiations.
This trend is likely to. continue in the future due to service 1eradiations for such companies as Foretics and TRW.
In addition, the neutron activation analysis ar.d radioassay areas saw increases in use and inquiries when compared to 1986.
Part of this increase was due to the acquisition of a new gamma spectroscopy system which went on-line in late 1986.
The software development program with the International Atomic Energy Agency continued during 1987 and the Nuclear Science Center again participated in the U.S.
DOE Reactor Sharing Program.
Core VIII-A, which has been ope rational since March 1986, was used throughout 1987 Pulse operations were continued in 1987 and a total of 45 pulses ($68.03 total pulse reactivity) were executed.
The decrease in operaticn in the pulse mode reflects the current lack of interest in reactor experiments requiring pulsing operations.
Pulsing operations for 1987 were due basically to calibration and maintenance requirements and engineering labs.
The new control rod drive and controller electronics continued to undergo troubleshooting modifications in 1987 but now appear to have reached their final form.
The thermal column experiment was fully implemented during 1986 with production of film taking place.
A new device, a heavy water filled "box" was constructed during 1957 for use in neutron transmutation doping and boron content determina-
2 tion experiments.
And finally, two new high purity germanium detectors were obtained during the year to replace one of the older, Ge(Li) detectors that had been on loan to the NSC and to provide a new detector for use on the Lower Research Level.
Besm Port 1 was revived during the past year and some neutron scattering work done.
Plans are underway to develop a prompt gamma activation analysis capability using this beam port and one of the new detectors mentioned earlier.
Several operational problems occurred in 1987 but none resulted in significant losses of operating time.
Work continued with the secondary water treatment system to attempt to improve performance, and equipment age continued to be the leading cause of reactor down-time.
In the latter part of the year, the use of acid in the secondary treatment system was discontinued which is hoped to decrease system upkeep and danger to personnel.
During this reporting period there were no changes made to the site area.
Spare equipment for possible future expansion and use was obtained from various sources.
In September 1987, Dr. Kevan Crawford was hired to fill the position of Manager of Reactor Operations and John Krohn was named Assistant Director while retaining his position as Manager of Technical Services.
At the July Reactor Safety Board the NSC's plans to replace the Head of the Nuclear Engineering Department with the Director of Research Reactor Programs in the NSC organizational enart was approved by the Board.
This change has been submitted to the NFC as a license amendment.

14 D20 Moderated Rotisserie Irradiation Device The D 0 moderated rotisserie irradiation device is designed to 2
provide sample exposure to thermal neutrons with a very small fast neutron component.
There are three irradiation positions which provide increasing thermal to fast neutron ratios with increasing The D 0 irradiation device and installa-distance from the reactor.
2 tion is shown in Figure 2.
The irradiation device consists of an aluminum stand which is positioned on centerline of the pool floor, a sealed aluminum inner box containing D 0, a water tight outer aluminum box, an electric 2
motor and drive unit, the rotisserie irradiation tubes, and graphite or air filled plugs for placement into the irradiation positions when not in use.
The inner aluminum box is anodized to protect against Al-D 0 interactions and has reinforcement ribbing to increase strength 2
and act as a spacer when placed inside the outer box.
Both the inner and outer boxes were leak tested before being put into service.
The double container design will prevent contamination of the D 0 by pool 2
water in the event of leakage of the outer container and prevent the loss of D 0 into the pool due to leakage from the inner tank.
The 2
space between the inner and outer box is helium filled.
The outer box also has external ribbing for strength and the end away from the reactor is flanged.
The large flange has two small service / main-tenance flanges to provide access to the stainless steel bellows valves on the inner box to be used for D 0 transfers.
Under normal 2
conditions the valves will be shut off and capped.
The gasket material used to seal the flanges is "Grafo11" (pure graphite) which will resist radiation damage and has been used successfully at the NSCR for other in-pool /high radiation level applications.
Sampling fittings are located on each of the service flanges to provide fo r sampling of gases inside the outer box.
All nuts, bolts, and washers used in the device are stainless steel.
The device is monitored for temperature, pressure, and water leakage.
A pressure transducer and thermocouple have been placed inside'the inner box to monitor the temperature and pressure of the D 0.
A conductivity circuit is also inside the outer box to monitor 2
for D 0 or pool water leaks.
The monitors are connected to a poolside 2
monitoring station through poly tubing containing two wire pairs which enters the device near the back flange.
C.
Operational Problems Control Rod Drive Controller Modifications The control rod drive controller units experienced occasional problems in erroneous rod position indication due to electronic noise interference.
The controller main circuit board was replaced with a new version that incorporated both previous modifications and new circuitry.
Circuit interlock additions and increased motor direction monitoring have decreased the possibility of noise signal inter-Terence.

16 Transient Rod Drive Switching The transient rod drive utilizes solid state switching for motor control.
A failure of the "down" control module prevented the carriage from withdrawing.
Unusual line power surges and loss of building power was determined as the cause of failure.
The module was replaced with no further problems.
Secondary Pump Shaft Coupling The secondary pump shaft coupler broke during cooling system operation.
Metal fatigue and corrosion was the apparent cause of failure.
A complete overhaul was performed with new bearings installed, the motor was rewound, and a new strainer was installed.
A new parallel pump system is planned for installation in 1988.

F.
Reactor Maintenance and Surveillance 1.
The Technical Specification requirements for maintenance and surveillance were completed for all following required channels:
Fuel Element Temperature Measuring Channel Linear Power Channel Log Power Channel High Power (Safety) Channels Facility Air Monitoring Channels Area Radiation Monitoring Channels All control rods were calibrated on January 26, 1987 with a total rod worth of $15 31 and a shutdown margin of $2.69 The power level (linear) channel was calib Tted by the calori-metric method on 1/8/87 The rod scram time checks resulted in times less than the Technical Specification limit of 1.2 seconds.
Fuel elements requiring inspection were inspected on 7 January 1987.
All other required maintenance as set forth in the Technical Specifications was performed annually, semi-annually, or weekly as.aequired.
This was in addition to completion of a pre-startup checklist done daily prior to reactor operation.
2.
A pulse test program for Core VIII-A was conducted on 7 August 1986 to determine the maximum allowable reactivity insertion for Core VIII-A as required by Tech Spec 3.1.2.
The test program produced an insertion limit of $2.09 and an adminis-trative limit of $1.90 was imposed by memo on 28 August 1986.
18 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.
3 The reactivity worth for each experiment was measured as appropriate before reactor operation with the experiment.
The most reactive experiment irradiated was the Thermal Column coupler with a value of $1.35 4.
Emergency evacuation drills were conducted on March 4 and August 13, 1987.
5 A review of the NSC security plan and emergency plan was con-ducted by the NSC staff and the Reactor Safety Board on 1/30/87.
6.
A review of the NSC ALARA program was conducted by the NSC staff and the Reactor Safety Board on 1/30/87.

V-2 EFFLUENT RELEASE
SUMMARY
Introduction Summaries of radioactive effluents released from the Nuclear Science Center for 1987 are included in this Appendix.
These data are presented in tabular form and include 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 release rate was 1.27 E-11 pCi/cc.
Total radioactivity released for the year was 9.43 E-04 curies.
These data, presented in Table 1,
represent output of the Nuclear Science Center Facility Air Monitoring System.
The individual particulate monitors in this system detect gross beta and gamma radiations emitted from filtered particulate material without regard to the origin or half-life of the radioactive materials.
Other than naturally-occurring Radon / Thoron progeny, particulates with half-lives exceeding eight days were identified only once.
In May, 1987, Cerium-139 was identified on filter paper removed from the stack exhaust particulate monitor (Channel 1).
Less than 1%
of the activity released in May 1987 was identified as Ce-139 resulting in a release totaling 0.25 uC1 resulting in an average site boundary concentration of 2.0 E-16 u C1/cc or 0.0002% of the Un-restricted Area Maximum Permissi'0!.e Concentration (MPC) for Cerium-139 Gaseous Releases Argon-41 is the major gasecous ef fluent 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 1987 was 8.28 curies.
This results in an annual average release rate of 1.11 E-07 uCi/cc as 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 <1.4% 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.
Solid Radioactive Waste 8
There was a total of 38 ft of uncompacted dry solid waste material packaged in plastic bags for disposal during 1987.
These materials are transferred to the Radiological Safety Office, Texas License 6-448, for disposal.
This material consisted of laboratory glassware, irradiation containers, decontamination materials, and expendable protective clothing and equipment, e.g.,
paper, shoe covers, plastic bags and gloves.
This material contained Co-60, 4
.V-3 Ir-192, Zn-65, and Mn-54 with the total radioactivity being 2.5 E-04 C1.
These data are in Table 3 Liquid Waste Releases Radioactive liquid effluents are collected in liquid waste holdup tanks prior to release from the confines of the Nuclear Science Center.
Sample analyses for radioisotope identification and radio-activity concentrations were determined for each release.
There were 24 liquid waste releases totalirg 1.09 E+09 ml including diluents from the Nuclear Science Center durir.g 1987 The total radioactivity released for 1987 was 1.48 E-02 Ci with an average concentration of 1 35 E-05 pCi/ml.
Summaries of the radioisotope data are presented in Table 4 through 16.
Radioactivity concentrations for each isotope were below the limits specified in 10CFR20, Appendix B, Table II, Column 2.

f ENVIRONMENTAL SURVEY PROGRAM Introduction 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 prior to their release.
The environmental survey program includes the in-situ measurement t
of integrated radiation exprsures at the site boundaries.
These measurements are made for e period of approximately 90 days using commercially available thermoluminescent dosimeters (TLD's) of lithium fluoride chips in glass encapsulated bulbs.
The dosimeters are pro-vided and processed by Texas Department of Health, Bureau of Radiation Control, Division of Environmental Programs.
The state utilizes a L
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 (261.4 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 i
beyond the Site Boundary fence directly behind the Site #10 monitoring i
location.
From the data in Table 17, it can be easily shown that those occupants received much less than twice the average local off-site background exposure.
Summaries of the environmental survey program for 1987 are pre-sented in Tables 18-22 for total (sum) gamma or total beta activity as reported to the NSC (or determined by the NSC in the case of the fourth quarter 1987).

V-27 PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science Center in 1987 were below the limits set forth in 10CFR20.101 with one excepcion.
The exception concerns a potential overexposure for one individual which was documented in a Radiation Safety Office Memo-randum sent to the Texas Department of Health, Bureau of Radiation Control and a similar Nuclear Science Center Memorandum sent to the U.S. Nuclear Regulatory. Commission's Region IV Office.
i The reported overexposure occurred during a period between mid-September and November 12, 1987 as a result of experimental beam port work.
The individual wore a Landauer-supplied thermoluminescent dosimetry (TLD) in a mixed gamma and neutron field.
The_ total re-ported exposure for the period mentioned was 6.86 rem, whole body dose, and 6.96 rem for all of 1987.
The investigation into the ex-posure at'the beam port facility is still in progress.
When com-pleted, a full report including recommendations for proper adjustment of the recordeo dose will be submitted to the NRC.
With the exception of the potential overexposure, the maximum exposure received by any individual for the year was 280 mrem.
A total of 3 24 MANREM was received for 1987 (10.2 MANREM including the overexposure as reported)..
The access control procedures for visiting personnel were effective in preventing measurable exposures to radiation.
During 1987, 3745 persons visited the Nuclear Science Center.
The maximum exposure to any visitor as determined by film badges was less than the minimum measurable quantities:
10 millirem for X or gamma, 40 millirem for hard beta, 20 millirem for fast neutrons, and 10 milli-rem for thermal neutron radiations.

V-29 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 system consisting of nine (9) 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 impending radiation hazards.
The Nuclear Science Center facilities and site boundaries are surveyed monthly with beta-gamma sensitive instruments.
These measurements are taken v
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, no unexpected radiation levels were detected in 1987.
Within the NSC facility, radiation areas and high radiation areas were identified and posted in accor-dance with state and federal regulations and NSC procedural require-ments.
Contamination Survey The Nuclear Science Center is routinely surveyed for radioactive contamination every month.
This program includes the collection, analysis and evaluation of approximately 250 smear samples and the decontamination of areas and materials with removable beta-gamma 2
radioactivities of greater than 1000 dpm/100 cm.
