1 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 State of Texas. The facility is available to the University, other educational institutions, governmental agencies, and private organizations and individuals. The facility operating license R-83 issued by the U.S. Nuclear Regulatory Commission, was renewed in March, 1983 and 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 USDOE Contract Number DE-AC05-76ER04207 (formerly EY-76-C-05-4207) and of the USNRC, under 10CFR50.59 The report covers the period from January 1, 1986 through December 31, 1986.
Utilization of the reactor during 1986 was approximately the same as during 1985 The total hours of operation, number of irra-diations and sample irradiation hours all increased slightly over 1985 levels while the total MW-days of operation and number of samples irradiated decreased slightly. The continuing slump in the oil business was one ' contributing factor in the recent decreases in utilization. Early indications point to a rebound in utilization during 1987. The software development program with the International Atomic Energy Agency continued during 1986 and the Nuclear Science Center again participated in the U.S. DOE Reactor Sharing Program.
Core VIII, which has been operational since December 1982, was used during the first half of 1986. In March, Core VIIIA was declared operational, and in June Core VIIIA was put into everyday use. Pulse operations were continued in 1986 and a total of 137 pulses ($232.70 total pulse reactivity) were executed.
The new control rod drive and controller electronics were in-stalled on the remaining control rods during 1986 and a new extension was added to the thermal column which had been out of use for several years.
Several operational problems occurred in 1986 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 area of non-reactor equipment, a new gamma spectroscopy system was purchased during the year, and is expected to fully re-place the existing system in early 1987.
D.uring this reporting period there were no changes made to the site area. The extension of the main runway at Easterwood Airport was completed during 1986, and resulted only in an extension of the approach road to the NSC. The electric gate to the facility required ex'ensive rewiring during 1986 due to water damage.
l
2 In_ February, 1986, Don Anderson retired from his position of Manager of Reactor Operations and John Krohn was named Manager of Reactor Operations while retaining his position as Manager of Technical Services. In September, 1986, Dr. Jon Reuscher was'added to the staff of the Texas Engineering Experiment Station as the Director of Nuclear Research Reactor Programs. At the same time, Dr.
Gerald Schlapper resigned his half-time position as Associate Director. The organizational structure for administration of the NSCR was not altered by these personnel changes.

3 II. REACTOR UTILIZATION A. Utilization Summary Utilization of the NSCR during the reporting period is shown in Figure 1 and Table I. Figure 1 presents reactor opera-tion from January 1975 through December 1986. During the present reporting period the NSCR was used by approximately 1365 students (includes 689 involved in tours or lab work and 26 student re-searchers) and 36 faculty and staff members representing 15 departments at Texas A&M University. In addition, more than 220 faculty and students from 11 other educational institutions used the facilities, and 4,579 visitors were registered during 1986 including several public and private school groups. A total of 23 non-university organizations had programs that were depen-dent upon the NSCR.
On numerous occasions throughout the year the NSCR was toured by a total of 93 visiting military officers from virtually every free world country. These officers have been receiving training and indoctrination at Lackland Air Force Base, San Antonio, Texas.
Eight potential power plant reactor operators from Houston Lighting and Power were trained in 1986. Each candidate per-formed 10 reactor startups to fulfill a portion of their licensing requirements.
During twenty three years of operation, the NSC has provided services to 41 departments at Texas A&M University, 111 other colleges and universities, 96 industrial organizations, and 22 j federal and state agencies. (See Appendix III and IV for l, listings). l B. Utilization by the Texas A&M University System During 1986 the following personnel from various departments at Texas A&M University used the NSCR for research. Appendix I describes sorse of the projects completed.

13 III. FACILITY OPERATIONS A. Facility Safety and Operational Improvements Secondary Treatment Controller An updated secondary water treatment controller was built and installed by electronics shop personnel. The new unit allows for an increase in control parameters and also provides visual indication of various system functions.
Heat Exchanger Room Sump Pump Liquid waste from the NSC laboratory building flows to a sump in the valve area of the heat exchanger room. A sump pump is used to transfer this liquid to the main sump in the demineralizer room. The exchanger room sump pump was modified to include an indication in the control room of pump operation plus an indication of liquid level in the sump.
Auxillary Waste Tank Tap i The auxillary tank is normally empty and not on-line for routine
- storage of radioactive waste. It is, however, sometimes used to store an emergency supply of city water for the cooling tower. A tap was added to the auxillary waste tank between the tank and the drain valve. The addition of this tap, which is normally closed off by a plug, allows this emergency supply to be drained directly into the cooling tower. The tap is located such that it presents no more hazard for loss of radioactive waste than do the sample lines on all three waste tanks.
B. Improvements to Reactor Systems and Experimental Facilities Shim Safety Drive Unit Modifications The conversion of the rod drive units to a new system of determining carriage position, as begun in 1985 under Modification Authorization M-32 was completed in 1986. The new method involves a counting' circuit using photo-electronics with up-down counters that
! measure travel by counting motor revolutions, with automatic stops at 0% and 100%.
Regulating Rod Drive and Console Controller The regulating rod drive was also converted from a mechanical switch unit to one utilizing the photo-electronics counting system.
The original analog controller with a cm travel indication was
. replaced by a digital unit with $ position indication. This modifica-tion was also carried out under M-32.

14 Rotisserie Drive System The change in 1986 to Core VIII-A allowed for up to three rotisseries (irradiation devices) to be utilized simultaneously. A new drive system was fabricated using one motor and a gear drive to replace the previous system that used a motor for each rotisserie.
Power Interruption Circuit A circuit safeguard was installed into the reactor console power, as per Modification Authorization M-13-1, to prevent inadvertent application of power to rod control circuits following a power failure. Restoration of power to the facility must be followed by a manual reset of console power in order to apply power to the rod drive units.
Linear Channel Picoammeter The Linear Power Channel picoammer,er utilizes an analog meter face that previously had a scale from 0-10 with a corresponding recorder scale of 0-150%. Normal operation of the reactor was at a 100% indi-cation on the recorder; subsequently the picoammeter indication was 6.67. Changes from this setpoint typically required calculation of the correct indication due to the scale involved. A change was approved (Modification Authorization M-33) to convert the picoammeter scale to a 0-150% span to directly correspond to the recorder indication.
Thermal Column Extension The ability to provide Thermal Column and Beam Ports users with reactor services was made possible by the installation of a Thermal Column extension box under Modification Authorization M-34 which brings the Thermal Column face further into the stall. Used with various coupler boxes mounted on the extension, a variety of experiments may be performed simultaneously. A cross sectional view of the extension box is given in Figure 2.
Stall Gate Gasket Repair The stall gate uses tubular rubber gaskets to obtain the seal necessary for draining of the stall. Deterioration of the original gaskets prompted a replacement of same which was accomplished by removal of the gate (32 ft in length) from the pool and placement of the gate across the stall and reactor rails. The gaskets on the main pool side of the gate are scheduled for replacement at a later date.

16 New Gamma Spectroscopy System A new gamma spectroscopy system was purchased during the year to replace the Canberra SCORPIO system in use since 1977. The new system is a Nuclear Data 9900 series (Genie system) integrated Multichannel Analyzer System. The system utilizes a Digital Equipment Corporation Microvax II computer and can simultaneously collect data from up to four detectors and be used by up to eight users at one time. This new system offers a vast improvement in processing time, memory capacity ,
and ease of use over the existing system.
C. Operational Problems Reportable Occurrence No. 86-1 Failure of Fuel Temperature Recorder On 4 February 1986 during pulsing of the NSCR the temperature re-
! corder which monitors fuel temperature failed to respond properly.
4 Digital temperature indication was normal. The temperature recorder
- provides the required scram signal in the event of high fuel
- temperature and its failure to respond correctly during routine pulsing resulted in classification as a Reportable Occurrence.
- Operation was suspended and investigation found the problem to be bad recorder motor bearings which were replaced. Recorder maintenance and calibration was performed and the system returned to service 5 February 1986.
Reportable Occurrence No. 86-2 Unanticipated Change in Reactivity Greater Than One Dollar When the reactor startup to 1 MW was completed on 1 May 1986 the
, operator noted higher than expected control rod heights. Investiga-tion revealed an unscheduled experiment in a core face notch. The experiment was intended to be in the reactor only during shutdown periods. Subsequent power reduction and experiment removal resulted in an unanticipated power increase and a high-power automatic scram (shutdown).
With the sample removed and all indications normal the reactor underwent a second startup to 1 MW. Using data from both startups the reactivity worth (the effect the sample has on reactor power) was determined to be higher than estimated. The value exceeded the NSCR Technical Specification limit and was therefore a Reportable Occurrence. The same experiment was also involved in a reactor scram at an earlier date under similar but low-power conditions. NRC notification and subsequent investigation indicated a lack of communi-cations, failure to follow procedures, inadequate log keeping, and a failure to follow adequate corrective action from the previous similar incident as major causes for the 1 May incident. Increased training and some procedural changes were implemented in an effort to avoid re-a j
17 occurrence of this incident, in addition to stressing an increase in operator awareness. The NRC also held an Enforcement Conference in regards to this Reportable Occurrence.
Reportable Occurrence 86-3 Transient Rod Component Malfunction On 8 July 1986 a manual scram was performed for the purpose of reactor shutdown. At that time it was noted that no rod down indica-tion was received for the transient rod. Investigation by the SRO revealed that the rod had stopped approximately 15% above bottom. The rod was fully inserted by cylinder insertion. All other control rods performed their intended function allowing adequate shutdown of the reactor. During subsequent testing on 9 July it was noted that raising the TR carriage without air applied caused the rod to be lifted from its down position. Friction within the TR cylinder was the apparent reason for the rod to rise without air applied. The TR cylinder and drive unit was removed for repair. Inspection revealed grit and foreign matter in the rubber lip seal area. The seal was replaced and all components cleaned. The unit was tested and returned to service on 10 July 1986. The frequency of checking the transient rod drop time has been increased from semi-annually to quarterly.
D. Changes in Operating Procedures Changes to the following SOP's were reviewed and approved by the RSB during the reporting period:
SOP's I-A Definitions and Abbreviations I-G Distribution and Binding (EA's and MA's)
II-A General Organization and Responsibilities II-C Reactor Startup II-D Steady State Operation II-F Reactor Shutdown II-J Power Calibration II-L Pulse Calibration II-0 RO and SRO Requal (deleted)
III-C Linear Power Measuring Channel Maintenance III-P Millivolt Potentiometer Maintenance (deleted)
IV-A Experiment Approval IV-E Irradiation Cell Experiments X-A Requa.lification Program
1 18 E. Unscheduled Shutdowns A total of twelve unscheduled shutdowns occurred during 1986. The unscheduled shutdowns can be arranged in the following categories:
Cause of Shutdowns Number of Shutdowns Building power loss 3 Operations error 6 Electronics a) Channel failure 1 b) Rod drops 2 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 I.rea Radiation Monitoring Channels All control rods were calibrated on February 3, 1986 with a total rod worth of $15.01 and a shutdown margin of $3 63 The power level (linear) channel was calibrated by the calori-metric method on 1/6/86 and 3/25/86.
The rod scram time checks resulted in times less than the Technical Specification limit of 1.2 seconds.
Operability of the pulse mode was verified by semi-annual pulsing for comparison of pulse energy and temperature.
Fuel elements requiring inspection were inspected on 7 January 1986.
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.
- 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 s
)
19 I
program produced an insertion. limit of $2.09 and an adminis--
trative limit of $1 90 was imposed by memo on'28 August.
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. An emergency evacuation drill was conducted on May 30, 1986.
5 A review of the NSC security plan and emergency plan was con-ducted by the NSC staff and the Reactor Safety Board on 1/31/86.
- 6. A review of the NSC ALARA program was conducted by the NSC' staff and the Reactor Safety Board on 1/31/86.
20 IV. FACILITY ADMINISTRATION A. Organization The organization chart for reactor operations at the Nuclear Science Center is presented in Figure 3 During this reporting period Don Anderson retired as Manager of Reactor Operations and John Krohn assumed this title. Dr. Gerald Schlapper has left the NSC as an Associate Director and Dr. Jon Reuscher has joined TEES as the Director of Nuclear Research Reactor Programs. Scott Thomas resigned from his position of Senior Reactor Operator to finish his degree work and Mark Stowers was hired to fill this budget position and entered a training program. Frank Stagg and J. Wesley Davis received operator licenses during the year and Tom Blanchat and John Krohn received SRO licenses. The problems of personnel turn-over continued and an increase in hours of operation also created problems of a shortage of licensed individuals at times.

V-2 i EFFLUENT RELEASE
SUMMARY
i j Introduction i Summaries ~of radioactive effluents released from the Nuclear Science Center for 1986 are included in this Appendix. These data are presented in tabular form and include atmospheric, liquid and solid
- ' waste releases.
l Particulate Releases i
Radioactive particulates are monitored at the base of-the; central exhaust stack and summarized on a monthly basis. . The annual average release rate was 3.49 E-11 pCi/cc. Total radioactivity released'for i the year was 2.60 E-03 curies. These data, presented in Table 1, represent output of the Nuclear Science Center Facility Air Monitoring-i 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 i materials. Other t naturally-occurring Radon / Thoron progeny, particulates with h 1 -lives exceeding eight days were identified only -
once. In July, 1986, Cobalt-60 was identified on filter-paper removed -
j from the stack exhaust particulate monitor'(Channel 1). If all of the activity released in July 1986 was assumed to be Cobalt-60, the
- release would total 25.9 pCi resulting in an average site boundary j concentration of 2.05 E-14 pCi/cc or 0.007% of the Unrestricted Area i
Maximum Permissible Concentration (MPC) for. Cobalt-60.
Included in the particulate release values calculated for 1986 are the "as-recorded" results of one accidental release of radioactive
! materials. On December 18, 1986, offgas from an irradiated sample was i released accidentally into a fume hood which then dumps into the
! central exhaust system. The offgas contained Bromine-82, a 35-hour 3
half-life isotope which is chemically very reactive. Although de-i tection of this release by the stack particulate monit ar resulted in-
! shut'down of all air handling systems thereby terminating the release
! of Br-82 to the environment, conservative estimates of the release l place the maximum possible activity release to the environment at 3 7-
! milli-curies. A full' report on the incident and the followup investi- ,
j gation is on file at the TAMU Nuclear Science Center. NRC' Region:IV !
, and the Texas Department of Health, Bureau of Radiation Control were !
! notified of the incident even though no federal, state, or facility I
- Technical Specification reporting requirements were exceeded. '
l 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 1986 was 16.6 curies. This results in an annual average release rate of 2.23 E-07 pCi/cc as measured in the central exhaust stack with no' dilution factors i

V-3 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 < 3% 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 There'was a total of 60 ft' of uncompacted dry solid waste material packaged in plastic bags for disposal during 1986. 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, Ir-192, Zn-65, and Mn-54 with the total radioactivity being 1.25 E-03 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 analys.es for radioisotope identification and radio-activity concentrations were determined for each release. There were 36 liquid waste releases totaling 1.458 E+09 ml including diluents from the Nuclear Science Center during 1986. The total radioactivity released for 1986 was 7.692 E-05 Ci with an average concentration of 5.276 E-08 uCi/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.

V-20 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 remained basically unchanged from 1985 and reflect the continued use of retention facilities and sample analysis for laboratory effluents prior to their release.
Sample analyses indicate that the activities are remaining at normal background levels in the unrestricted environment.
, The environmental survey program includes the in-situ measurement
! of integrated radiation exposures at the site boundaries. These measurements are made for a 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 i Control, Division of Environmental Programs. On March 26, 1986, the Texas Bureau of Radiation Control made several changes in monitoring locations, including changes in the location of several TLD sites.
Most notably, the location of the background monitor was moved from southeast of the airport (ESE of the NSC facility) to a point 5.25 i miles west-southwest of the NSC facility. The new site for the back-ground measurement is generally at right angles to the prevailing southeasterly winds. In addition, the state discontinued TLD monitoring at several locations around the NSC facility.
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 #6 (206.7 mR/yr) which is on the NSC Site Boundary fence and adjacent to the Radiological Safety Office's Radioactive Waste Storage Facility and Instrument Calibration Range. A significant but non-quantified portion of this exposure should be attributed to radioactive materials and sources stored at those facilities.
The closest offsite point of extended occupancy is located just i 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 occupants received much less than twice the average local off-site background exposure.
Summaries of the environmental survey program for 1986 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 after 3/26/87).

V-27 PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science Center for 1986 were well below the limits of 10CFR20. The maximum exposure received by an individual for the year was 520 mrem. A total of 3.19 MANREM was received for 1986. More important, the exposures reflect an extended effort by all personnel to minimize and eliminate radiation exposures whenever practicable. These exposure data become more significant when one considers that in addition to routine reactor operations, over 8,482 radioactive samples were produced and processed for shipment at the Nuclear Science Center in 1986.
The whole-body exposure data for NSC employees and experimental personnel are presented in Table 23 These data are presented in graded divisions as required under 10CFR20.202(a).
The access control procedures for visiting personnel were effective in preventing exposure to radiation. There were 4,579 visitors to the Nuclear Science Center during 1986. The maximum ex-posure to any visitor as determined by film badges was less than the minimum measurable quantities. These values are 10 millirems for X or gamma;, 40 millirems for hard beta, 20 millirems for fast neutrons and 10 millirems 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 aaterials, 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 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 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 1986. Within the NSC faclity, 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 2
beta-gamma "adioactivities of greater than 1000 dpm/100 cm .
