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 isseed 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 I the reporting requirements of USDOE Contract Number DE-AC05-76ER04207 (formerly EY-76-C-05-4207) and of the USNRC, 10CFR50.59 The report covers the period from January 1, 1985 through December 31, 1985.

Reactor utilization decreased from 1984 as indicated by a smaller number of samples irradinted and of total irradiations. In addition there was a decrease in megawatt-days of reactor operation and the number of hours at steady state. There was also a large decrease in the total number of experiment hours. The observed trend in reactor utilization appears to be a result of the reduced operating schedule begun in September, 1983, new price increases for services effective in January, 1985, and the slowdown in the oil industry over the past few years. A program with the International Atomic Energy Agency for developing and testing computer sof tware for use at research reactors was continued in 1985 Core VIII, which has been operational since December 1982, was I used throughout 1985 Pulse operations were reinitiated in February 1983 for the first time since 1976, and a total of 113 pulses

($466.90 total pulse reactivity) were executed in 1985 Several major facility projects, modifications, and improvements were completed during the past year. f. new control rod positioning method was developed and installed on shim safety rods 1 and 4 with the remainder of rods to be completed in 1986, and improvements were made to the liquid waste handling system.

Several operational problems occurred in 1985 but did not result in a significant loss of reactor operating time. The secondary cooling pump motor had to be replaced, and instrumentation age also was a factor in some repair down-time.

During this reporting period there were no changes made to the site area; however, work continued on extension of the runway at nearby Easterwood Airport. This extension should be completed in

-1986 but should have no affect on the air traffic patterns relative to the NSC.

I s1

2 In May, 1985, the Assistant Director, who also served as Manager of Reactor Operations, resigned. A temporary, part-time replacement, Don Anderson, who had previously filled the position of Manager of Reactor Operations at the NSC, assumed this position and will te j available until a full-time Manager of Reactor Operations is hired. i Hopefully, this position will be filled in early 1986 so that a I smooth transition can be accomplished. Also, Dr. Gerald Schlapper was added on a half-time basis as an Associate Director charged with increasing reactor utilization by TAMU users and to increase sponsored research.

I 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 1985 During the present reporting period the NSCR was used by approximately 1365 students (includes 1338 involved in tours or lab work and 27 student re-searchers) and 35 faculty and staff members representing 19 departments at Texas A&M University. In addition, more than 250 faculty and students from 8 other educational institutions used the facilities, and 4223 visitors were registered during 1985 including several public and private school groups. A total of 17 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 92 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.

Three potential power plant reactor operators from Gulf States Utilities were trained in 1985 Each candidate performed 10 reactor startups, and attended lectures and labs in Reactor Theory, Reactor Design, Console Manipulations, Power Calibra-tions, and Health Physics procedures.

Dt ring twenty two years of operation, the NSC has provided services to 41 departments at Texas A&M University, 110 other colleges and universities, 90 industrial organizations, and 22 federal and state agencies. (See Appendix III and IV for listings).

B. Utilization by the Texas A&M University System During 1985 the following personnel from various departments at Texas A&M University used the NSCR for research. Appendix I describes some of the projects completed.

I III. FACILITY OPER'.fIONS A. Facility Safety and Operatianal 7.oprovements I Lab Building Liquid Waste Sump The liquid waste generated by experimenter usage in the reactor lab building is transferred from a sump in the heat exchanger room to I the main sump in the damineralizer room. The pump handling this transfer was wired to give indication in the control room whenever in operation and if an overfilled condition exists. This was desirable due to the nature of the material involved and the remoteness of the pump.

Strainer Installation The possibility of solics being pumoed to the liquid waste holding tanks was alleviatcl by the lhata11ation of a strainer assembly on the main sump discharge. The strainer will trap the colids and allow for easy remcval ano disposal as solid waste.

B. Improvements _po,Renctor Sys_tems an_d_Ex,perimental Faqilities Skimmer Pump Systen During Jcnuary 1985 e new Jacuzzt pump was inst.alled in place of the existing pump. The new pump allows for continuous operation and better reliability with a cleaner pool surface as a benefit.

Pneumatic System CO2 Pneumatic system operation involves use of CO2 for transfer or I samples to and from the core. An audition to at) existing visual indication of sufficient pressure was installed in the form of a audible and visual alarm on the t'eactor conscle auxiliary Panalars..

The alarm is energiz6d by a drop in CO2 pre.ssure below approximatGly 60 psi, to allcw sufficient time for replenishing ti.e supply.

Secondary Cooling Pump During Eeptemb9r 1965 a new secoadary pump wac in. Stalled as a reolace-ment for tue origica.1 unit. Due to extreme s. ear of components tha I origitial pump was c7nsidered un;'e11able and due to the necessity of 3econd9fy cooling the f.ew pump wau put in cervice. During the in5tallation a pumper tfuck provided the necessary flow to allor fot I

continued reactor oparation.

__ w .

14 Secondary Treatment Mixing Pump Lack of reliability primarily due to component age and wear necessitated the replacement of the mixing pump used in the chemical I treatment of secondary cooling water. The new pump adds visual indi-cation of flow to assist in proper operation of the system.

Shim Safety Drive Unit Modifications The method of determining carriage position by use of mechanical switches is being phased out as the drive units are modified as per Modification Authorization 32. The new method involves a counting circuit using photo-electronics with up-down counters that measure travel by counting motor revolutions, with automatic motor stops at 0%

and 100%. Figures 2 and 3 detail the modified rod drive unit and the associated logic circuit. During 1985 SS1 and SS4 have undergone the change, with the other arive units being modified as scheduling permits.

C. Operational Problems Reportable Occurrences Reportable Occurrence No. 85-1 Fal, lure of Reactor Safety Systems During Operation - Fuel Temperature Recorder On 8 January 1985, following a drop in reactor power for sample loading, the fuel temperature recorder indication was 600'E at 1 MW instead of a normal reading of approximately 720 F. All other measuring channels indicated 1 MW. The recorder slidewire and contact I

arm were replaced following investigation, and instrument semi-annual maintenance was completed.

response was normal.

The reactor was started up and recorder Reportable Occurrence No. 85-2 Failure of Reactor Safety System During Operation - Safety Channel #1 I On 11 January 1985 the reactor was started uo following annual detector maintenance. At a power level of 400 KW Safety Channel #1 indicated 55. Detector adjustment yielded no change in indication.

The reactor was shutdown for electronic troubleshooting. Initially it was thought that signal cables for the pulse detector and safety chrnnel. #1 had been switched, but this was not verified. A second startup still yielded no response from safety channel #1. The reactor was shutdown, the pulse detector and cabling was swapped with safety I- channel #1, and a subsequent startup was performed with no problems.

The final conclusion was a detector failure in safety channel #1 followirg maintenance.

17 Repcrtable Occurrence No. 85-3 Reactor Operation Without Required Facility Air Monitors On 8 May 1985 the reactor was operated at 1 MW following a building power failure. As a result of the power loss, the health physicist on duty had secured the detector high voltage in the Facility Air Monitoring system. Shortly after reaching power the reactor operator observed improper response on the Facility Air Monitors, and the health physicist was notified. Detector high voltage was restored, and Facility Air Monitor response was normal.

The Area Radiation Monitors were in operation during the reactor startup and operation at 1 MW.

Reportable Occurrence No. 85-4 Transient Rod Solenoid Malfunction On 12 September 1985, with the NSCR at a power level of 300 watts in pt-eparation for a pulse, the transient rod followed the cylinder out during positioning of the transient rod cylinder. This malfunc-tion resulted in a positive reactivity insertion that was immediately corrected by the reactor operator. Visual observation showed that the transient rod would indeed rice at the same rate as the cylinder without air being applied. The reactor was shutdown for evaluation and correction.

Troubleshooting of the air supply system sh wed the air solenoid for air application was not sealing as required. The solenoi) was disassembled, cleaned, and reassembled and rod drop times were measured. Drop times met all technical specifications, and the NSCR was returned to service. Prior to installation of a repair kit, rod drop times were checked daily for rod operability.

On 8 October 1985 a repair kit was installed in the air solenoid.

After successful operability testing the system was returned to service.

Magnet Failures The electro-magnets used in coupling the control rods to the drive units experienced various problems throughout 1985, including coil failures, broken lead wires, and foreign substance deposits on the faces of the magnets. New magnet structures are being developed to improve reliability and to reduce maintenance of these units.

Pulse Mode Rod Withdrawal Interlock Failure During reactor system checkout on 9 September 1985 the interlock to prevent any control rod withdrawal while in pulse mode failed. Re-pair by electrenics personnel consisted of component replacement in the power supply for the startup channel scaler and interlock system.

Interlock logic was verified operable and operation was resumed.

I '8 Transient Rod Movement During Maintenance During the performance of quarterly maintenance to the Transient Rod system on 19 December 1985 the rod was observed lifting off bottom when the carriage was being raised. Air had not been applied to the system. Testing of the sygtem indicated friction between the cylinder walls and the transient rod seals was lifting the rod slightly off bottom. The performance of semi-annual maintenance corrected the I problem and operability tests were satisfactory.

D. Changes in Operating Procedures Changes to the following SOP's were reviewed and approved by the RSB during the reporting period:

19 E. Unscheduled Shutdowns A total of nineteen unscheduled shutdowns occurred during 1985.

Several were electronic in nature due to equipment age. The un-scheduled shutdowns can be arranged in the following categories:

Cause of Shutdowns Number of Shutdowns

-Building power loss 5 Operator error 2 Electronics a) Channel failure 1 b) Rod drops . 11 F. Reactor Maintenance and Surveillance

1. Semi-annual calibrations of the fuel temperature measuring channels were completed on 1-8-85 and 6-21-85 The LSSS was set at 525aC (975 F).

2. A channel check of the fuel element temperature measuring channel was made daily by recording and comparing the fuel element temperature and the pool water temperature prior to reactor startup.

3 Contrcl rod calibration for 1985 were as follows:

Core VIII (1-6-85)

Control Rod Rod 'dorth SS #1 $2.71 SS #2 1.68 SS #3 2 35 SS #4 4.25 RR .81 TR 2.81 Shutdown Margin 3.87

4. The reactivity worth of all experiments was either estimated or measured, as appropriate before reactor operation with the experiment. The most reactive experiment irradiated was the Beam Port #4 reflector with a value of $0 30.

I 5 The scram times of the control rods were measured for annual maintenance. The results are as follows:

Date Control Rod Time in Seconds 1-23-85 SS #1 .644 1-23-85 SS #2 .660 1-23-85 SS #3 .600 1-23-85 SS #4 770 1-23-85 TR .852

t 20 All rod scran time checks performed as required throughout the year resulted in times less than the 1.2 second limit set by Technical Specifications.

=

6. A channel test of each of the reactor safety system channels s for the intended mode of operation was performed prior to each O day's operation. The pool level alarm was tested weekly.

7 Channel calibrations were made of the power level monitoring channels by the calorimetric method as follows ?,

EFFLUENT RELEASE

SUMMARY

Introduction Summaries of radioactive effluents released frem the Nuclear Science Center for 1985 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 summarizgg,on a monthly basis. The annual average release rate was 1.25 x 10 _ PCi/ce. Total radicactivity released for the year was 2.086 x 10 ' curies. These data are presented in Table 1.

Gaseous Releases l

Argon-41 is the major gaseous effluent produced and released at the Nuclear Science Center. This effluent is measured by ocunting the Argon-41 photopeak in the gaseous discharges of the central exhaust stack. Total Argon-41 released during 1985 was .022 curies. This results in an annual average release rate of 2.45 x 10-1' pCi.cc as measured in the central exhaust stack with no dil;ution factors applied. Applying the dilution factor of 5.0 E-03 allowed at the alte boundary (as determined, SAR, pages 116-119, June 1980) results in radioactivity concentrations of <1% of the limits specified in 10CFR20, Appendix B, Table II, Column 1. These data are summarized on a monthly baais and presented in Table 2.

Liquid Waste Releases Radioactive liquid effluents are coll.ected in liquiQ waste holdup tanks priv. 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 '

40 liquid waste releases totaling 4.44 x 10' ml including diluents from the Nuclear Science Center during 1985. The total radioactivity I released for 1985 was 3 024 x 10-8 Ci with an average concentration of 6.811 E-06 pCi/ml. Summaries of the radioisotope data are presented in Table 3 through 15 Radloactivity concentrations for each isctcpe I were below the limits specified in 10CFR20, Appendix B.

ENVIRONMENTAL SUT.VEY 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 was expanded in 1977 to incluce 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. These dosimeters are provided and processed by Texas Department of Health, Division of Occupational Health and Radiation Control. Ambient back-ground for these measurements is determined from a control dosimeter located southeast of Easterwood Airport approximately 800 meters east of the Nuclear Science Center site. This location is at a right angle to the prevailing southeasterly winds which occur a large majority of the time on an annual basis.

Table 16 lists the average exposure rate above ambinet background for a number of locations at the site boundary. The highest exposure points at the north and west location of the site boundary. Addi-tionalloy, a dosimeter is located adjacent to the radioactive waste storage building and the instrument calibration range. Exposure data from this dosimeter is not considered as a result of rea'ctor opera-tions but does reflect the maximum site boundary exposure of 165 mR per year. This site boundary location is further protected from free access to the general public for an additional 100 meters of fenced Texas A&M University property.

Summaries of the environmental survey program for the last 2 quarters of 1984 and the first three quarters of 1985 are presented in Tables 17-21 for total (sum) gamma or total beta activity as reported to the NSC. Summaries for the last quarter of 1985 are not yet avhilable and will be included in the 1986 annual report.

PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science Center for 1985 were well below the limits of 10CFR20. The maximum exposure received by an individual for the year was 110 mrem. A total of .45 MANREM was received for 1985 More important, the exr iures reflect an extended effort by all personnel to minimize and e__minate radiation exposures whenever practicable. These exposure data become more significant when one considers that in addition to routine reactor operations, over 11,102 samples containing approximately 590 curies of radioactitity were produced and processed at the Nuclear Science Center in 1985 The whole-body exposure data for NSC employees and experimental personnel are presented in Table 22. 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 4223 visitors to the Nuclear Science Center during 1985 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.

I SOLID RADIOACTIVE WASTE There was a total of 23 ft' of dry solid waste material packaged in plastic bags for disposal during 1985 These materials are trans-ferred to the Radiological Safety Office, Texas License G-448, for disposal. This material consisted of laboratory glassware, irradia-tion containers, decontamination materials, and expendable protec-I tive clothing and equipment, e.g., paper, shoe covers, plastic bags and gloves. Th s material contained Co-60, Ir-192, Zn-65, and Mn-54 with the total radiaoctivity being 1.13 E-3 C1. These data are in Table 23 I

V-29 RADIATION AND CONTAMINATION CONTROL PROGRAM Introduction The detectiori and elimination of radiation hazards is an i 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, imprcper storage of radiaoctive materials, and unwarranted exposures to radiation.

s Radiation Survey s The Nuclear Science Center uses an area radiation monitoring systems 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

.i daily basis. This system functions as a radiation safety monitor for f 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

- g materials and that visitor and routine work areas are free of g 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. There were no unexpected radiation levels or improper exposures of radioactive materials detected durirg 1985 These surveys revealed only background radiations at t'le site perimeter L fence.

+

Contamination Survey

_I The Nuclear Science Center is routinely surveyed for radioactive contamination every month. This program includes the collection, I analysis and evaluation of approximately 250 smear aamples and the decontamination of areas and stored materials with removable beta-gamma radioactivities of greater than 200 dpm/100 cm2, t
