INTRODUCTION I
The Nuclear Science Center is operated by the Texas Engineer-l ing 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.
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 10CFR50.59 The report covers the period from January 1, 1981 through December 21, 1981.
Reactor Utilization continued at about the same pace as the previous year with an increase in the total number of irradiations, sample irradiation hours, number of samples irradiated, and total experiment hours.
Reactor operation of 105.36 Mw-days for 1901 shows a 16% increase over the previous year.
The reactor was not pulsed during the reporting period due to a restriction on pulsing until the fuel damage study is completed.
Core VII was established during this reporting period and was designed to flatten the reactor east face flux available to the multiple rotisserie irradiation device (MRID).
This was accomplished by making only minor modifications to the Core VI-A configuration.
Several major facili;y modifications and improvements were completed during the past year.
The redesign and renovation of the radioactive materials handling area was begun in 1980 and has now been completed.
This has resulted in improved handling of radioactive materials and reduced potential for the spread of radioactive contamination in the area.
In addition, the work begun in 1980 on the domestic sewer and storm sewer was completed in 1981.
The new system consists of a gravity feed to a subsurface septic I
tank from the upper levels of the reactor building and lift tanks for the lower level facilities.
Because of the continued expansion of services provided by the NSC and the need for additional office space several changes have been made to the lab building.
This included the renovation of I
labs and office spaces and the relocation of the machine shop to facilitate the construction of a training classroom.
Also, an increase in reactor utilization resulted in the installation of an additional west face rotisserie motor.
d 1
2 A high rate of personnel turnover at the Nuclear Science Center has continued to be a problem due to the high demand for experienced nuclear personnel and higher salary offers in industry.
There is, however, an effort being made to offer more competitive salaries in hopes of stabilizing the reactor operations and technical staffs.

FACILITY OPERATIONS A.
Facility Safety and Operational Improvements Material Handling Area Renovations A number of planned changes in the MHA to facilitate the storage and handling of radioactive materials were begun in 1980 and com-pleted during this past year.
Hot sinks, work cabinets, shield storage units, and sample storage units have been added and are as shown in Figure 2.
Storage Shed Expansion and Machine Shop Relocation Due to continued expansion at the NSC a new, larger storage shed was built, and in addition a new machine shop is being built adjacent to the storage shed.
Although not yet completed, work on the machine shop relocation is expected to be done in January, 1982.
B.
Improvements to Reactor Systems and Experimental Facilities New Core Lcadings Through April, 1981 Core VI (see Figure 3) continued to be the primary core loading with intermittent use of Core VI-A (see Figure 4) for neutron radiography due to the higher east face flux.
To flatten the east face flux available to the multiple rotisserie irradiation device (MRID) Core VII (see Figure 5) was loaded by adding an additional fuel bundle in F-2 to the Core VI-A design and repositioning the neutron source to the D-2/E-2 positions.
I The desired results were obtained, and the core was declared operational.
Lab Building Renovations Due to continued expansion of the services provided by the NSC and the need for additional office space several changes to the lab I
building were required during the past year.
As seen in Figure 6 new labs were established for the Center for Trace Characterization (CTC) and Shell Development Company.
In addition the mechanical shop was relocated to allow for completion of a new training class-room to include a projection room.
A new health physics gamma counting lab was established beneath Lab 4 to facilitate counting of pool samples.

Fuel Shipments Four separate fuel transfers occurred during the past year at the NSC.
On 25 February 1981 seven TRIGA FLIP elements were received from General Atomic Company in San Diego, California.
On 10 April 1981 a previously unwelded FLIP element was sent to General Atomic for welding and was received back with three new elements and an instrumented element on June 2, 1981.
The MTR element was removed from inventory and sent to Rockwell International on 4 December 1981.
Reactor Operator Training for Utilities A training program was designed and implemented by the staff at the NSC and was administered during the summer of 1981 to 18 potential reactor operators from the Gulf States Utility River I
Bend Unit.
The two week course was designed such that utility operators in training who have completed a lecture series in basic reactor theory and systems could obtain hands-on training at an operating research reactor facility.
In addition to the performance and evaluation of various reactor experiments each student was able to complete ten reactor startups to gain the requisite experience in that area.
Addition of West Face Rotisserie Motor Due to an increased volume of required face irradiations in the past year a new rotisserie motor assembly was installed for use with the A-3 grid position.
This provides a slightly lower flux level than the present A-5 rotisserie but has proven to be a valuable addition.
A remote motor control switch and a power on light have been installed in the control room.
Installation of New Beam Port Reflector During the past year it was discovered that the graphite within the old reflector box had collapsed, and at the same time it was desired to extract a neutron beam for BP #1 use.
It was, therefore, decided to design and install a new beam port reflector assembly.
The new design (see Figure 7 and 8) consists of two sealed aluminum sections bolted together such that a 0.6" water gap exists between the two sections.
This new addition allows for neutron extraction from both BP #1 and BP #4 with BP #4 seeing approximately five times the flux available from BP #1.
C.
Operational Problems l
l Storm Sewer and Wastewater Systems - Waste Storage Tank Leak As reported in the 1980 annual report work was begun on the design and construction of an adequate outfall structure, relocation I
of the radioactive holdup tanks, and associated dirt work to remove i
all subsurface erosion pockets.
Work continued in this area during g
g the past year with the installation of a new slab for the waste storage tanks and completion of the sewage system modification.

POSITIONING OF BEAM PORT REFLECTOR I
I 22 Following the movement of the waste storage tanks to the new slab it was discovered that leak was present in tank #1.
The repair of this tank is planned for 1982.
The new sewage system consists of a gravity feed to a subsurface septic tank from the upper levels of the reactor building and lift pumps for the lower level facilities.
Violation Due to Expired Senior Reactor Operator License (Reportable Occurrence)
I On 7 May 1981 during a check of reactor operator licenses and requalification status it was discovered that License No. SOP-3478, I
held by Gary W. Waldrep, had expired on 27 April 1981.
This placed the NSC in violation of 10CFR55.3(b) and NSCR Technical Specifications Section 6.la which requires a licensed SRO to be in direct control of the facility.
Mr. Waldrep was relieved of his duties until a I
new license was issued.
The incident was caused by a failure to follow administrative procedures, and a solution to the problem has been accomplished by assigning an operator with the responsi-bility of checking the folders on all licensed operators monthly to determine license and requalification status.
Any discrepancies or approaching expirations will be reported to NSC management.
Failure of Shim Safety
"*"ol Rod Low Source Count Interlock (Reportable Occurrence
~
During a reactor prestartup check of the NSCR it was determined that the interlock to prevent withdrawal of shim safety control rods for low source level was not functioning properly.
In the mal-function the circuit provided a low level interlock alarm but failed to pravent the withdrawal of shim safety control rods 1 and 4.
The problem was intermittent and it was finally determined that 22 VAC was superimposed on the 12VDC control rod drive signal.
I The installation of a lufd capacitor reduced the AC voltage to approximately 1 VAC, and the interlock and control rod drive circuits functioned normally.

I-l DESCRIPTION OF PROJECTS UTILIZING THE NSCR A.
Texas A&M University Veterinary Physiology TRACE ELEMENT CHARACTERIZATION OF ANIMAL DISEASES Personnel Dr. Dan Hightower -- Professor David Hobson -- Graduate Assistant Biological tissue samples were irradiated in an attempt to determine any relationship between trace element levels and various Cl, K, Br, I, Cr, As, Cu, Mn, and Zn.
DETERMINATION OF IODINE IN VARIOUS BIOLOGICAL MATRICES Personnel Dr. Dan Hightower -- Professor David Hobson -- Graduate Assistant The purpose of this experiment is to determine whether or not I
protein bound and total iodine levels in various biological matrices (urine, blood, feces, saliva, etc.) can be measured accurately and rapidly using NAA procedures.
The work is part of a federal study on the possible detrimental effects of certain food colorings.
Pigs are used as the experimental animal.
Radiological Safety Office - Nuclear Engineering Department DETERMINATION OF THE DOSE EQUIVALENT INDEX (DEI) FOR A SOURCE OF N s GAMMA'S AND EXPERIMENTAL CALIBRATIONS OF PERSONNEL i
NEUTRON DOSIMETERS Personnel Dr.
R.
D.
Neff -- Radiological Safety Officer and Professor Joe P.
Holland -- Graduate Assistant This work is associated with the calibration of very precise instruments used for radiation dosimetry calibrations.
- Normally, calibrations of radiation dosimetry instruments are obtained from the National Bureau of Standards (NBS); however, NBS does not provide calibrations for the high energy photons requested in the work description.
In addition, the work involves the use of a
I-2 special instrument, an extrapolation chamber embedded in a tissue equivalent phantom.
This is a noval device developed by Batelle through a contract from the Department of Energy.
Chemistry TRACE ANALYSIS OF CEMENTS Personnel Dr. Thomas Vickery -- Assistant Professor Neil Roche -- Graduate Assistant The trace elements analyzed will be used in the establishment of a procedure for the " fingerprinting" of cements.
NAA is used here to acquire (1) a profile of the elements present in the samples, (2) a quantitative determination of the concentration of the trace elements of interest.
This information would complement any further data obtained from other methods.
EQUILIBRIUM STUDY OF SODIUM-POTASSIUM-HYDROGEN EXCHANGE ON CRYSTALLINE ZIRCONIUM PHOSPHATES Personnel Dr.
A.
Clearfield -- Professor Dr.
L. Kullberg -- Research Associate Using the NSC for activation analysis, isotherms for the ion-exchange of sodium-potassium-hydrogen in crystalline Zirconium phosphates have been determined.
The phases formed during the exchange were also identified.
TRITIUM AND SILICON-31 PRODUCTION PROJECT Personnel Dr. Yi-Noo Tang -- Professor Dr.
E.
E.
Sie fert -- Post Doctorate Recoil tritium atoms, generated from 3He(n,p)3H process with thermal neutrons from the reactor, reacted with organic compounds such as C H F, C H C1 and C-C Hs to yield products either from 2 5 2 5 4
abstraction or substitution.
The substituted products that fo rme d carried a large amount of residual energy.
The pressure deper.dence of the unimolecular decompositions of these substitutional products has been investigated under a very wide range of pressure including the use of large aluminum containers for low pressure studies.
The results indicated that (1) essentially all excited molecules will decompose under a very low pressure condition, and (2) the fraction decomposed (or stabilized) varied as a linear function of log P eff*
I-3 The effective pressure P consideration the relat19kp, was calculated by taking into collisional coefficient of the component molecules in each system.
Further studies on pressure effect and the analysis of ener,etics of these and other similar systems are in progress.
The reactions of recoil 31 Si atoms formed by the nuclear 31P(n,p)31Si, have been studied.
In such systems, transformation, it has been shown that recoil 31 31 atoms will abstract either H from PH3 or F from PF3 to give the corresponding silylenes, 31SiH2 31 or SiF The reactions of the silylenes thus formed with various 2
conjugated dienes are the major concern of this program.
It has I
been shown that these silylenes formed in the nuclear recoil system cor *st of about 20% signlet and 80% triplet.
The addition of sily eras in all of these forms will add to conj ugated dienes to give **e corresponding silacy-clopent-3-enes.
The relative reactiv cies of the butadiene, various pentadienes, and hexadienes are being studied and the nature of a large steric effect observed in some of the addition reactions is under serious consideration.
Center for Energy and Mineral Resources - Chemistry Department TRACE ELEMENTS IN LIGNITES Personnel Dr. Ralph Zingaro -- Professor Dr. Mysore Mohan -- Research Associate The present energy situation is a painful reminder of the urgent necessity of utilizing energy resources other than oil.
It can be anticipated with reasonable certainty, that increasing demands will be placed on coal and nuclear energy resources of the country.
Texas lignite deposits occupy a unique place in this scheme since, apart from being an obvious source of combustible fuel, they are rich in uranium.
The primary goal of the project is to gain an understanding of the chemical nature of uranium in these deposits.
The first steps will involve the preparation of enriched and unmodified samples.
Size-gractionation, density-gradient fractionation and flotation will be some of the methods used in the enrichment procedure.
Facilities at the Nuclear Science Center will be used to determine uranium content in these fractions by neutron activation analysis.
The uranium-rich fractions will be examined by ultraviolet, infrared, Raman and mass spectroscopy to obtain specific information about the chemical nature of uranium in 1:.gnite.

Huang -- Associate Professor C. Conrad -- Graduate Assistant W. Schaftenaar -- Graduate Assistant I
Students working under the above faculty members performed various studies of the uranium concentration and distribution in several different regions of Texas.
Some of these were in areas I
where exploration and/or production of uranium is underway, others address regions where the potential for exploration is of interest.
The following did work of this natore using both the delayed neutron method for concentration assay and the fission-track I
technique for distribution analyses:
E. Ledger (Ph.D.) - " Uranium in Volcaniclastic Sediments of the I
Catahoula Formation of Texas" B. Bomber (M.S.) - " Uranium Mineralization Along a Fault Plane in Tertiary Sedimentary Rocks" I

" Uranium Roll Front Study in the Upper Jackson Group, Alascona County, Texas" URANIUM LEACHING PROJECT Personnel Dr. Wen H.
Huang -- Associate Pro fessor Kendall Pickett -- Graduate Assistant This work addressed the feasibility of a particular method of leaching uranium from sandstones and lignites.
The objective was to use neutron activation analysis to measure levels of uranium as I
well as other trace elements such as Mo, As, Fe, Ca, Te, Se, V,
and Si in the product and wash.
The work would ultimately help determine the selectivity of various leaching processes.

Presley -- Associate Professor Dr.
P.
N. Boothe -- Research Associate Tony Tripp -- Graluate Assistant Fred Fenner -- Graduate Assistant
l I-5 The NSC facilities were used to determine the levels of vanadium (V), barium (Ba) and other trace elements (when possible) in various sample types by neutron activation analysis.
These samples included spiny oyster tissue (Spondylus Americanus) and both leaches and total digests of marine sediments.
These I
samples were collected as part of the Bureau of Land Management's Gulf of Mexico Topographic Features Study.
Most came from the vicinity of the East Flower Gardens Bank.
The primary purpose of I
these analyses is to determine baseline levels of trace metals in the biota and sediments from these biologically important fishing banks on the outer continental shelf.
These data will be used to evaluate the impact which present and future oil and gas exploration and production may have on these potentially sensitive reef communities.
The expected level of V in Spondylus samples is about 10 ppm.
The levels of Ba and V in the sediment samples should be 300 ppm and < 100 ppm respectively.
SEDIMENT DEPOSITION MEASUREMENTS IN THE GULF OF MEXICO USING CS-137 Personnel Dr.
B. J.
Presley -- Associate Professor Ron Pflaum -- Graduate Assistant Using fallout Cs-137 as a tracer, sediment deposition was examined in the Gulf of Mexico.
Samples were counted on equipment located at the NSC and data were obtained on the areas and rates of sediment deposition.
ANALYSIS OF OCEAN SEDIMENT FOR TRACE METALS Personnel Dr.
B. J.
Presley -- Associate Professor Ron Pflaum -- Graduate Assistant In conjunction with other research funded by the American Petroleum Industry various ocean sediment samples were collected.
Using NAA the samples were analyzed for V-52 and other trace metals.
This data will eventually be part of a report on the amount of pollution present around Gulf Coast oil rigs.

III-2 EFFLUENT RELEASE
SUMMARY
Introduction Summaries of radioactive effluents released from the Nuclear Science Center for 1981 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 3.53 E 11 pC1/ce.
Total tadio-activity released for the year was 2.63 E-03 curies.
There were 5 radioisotopes with > 8 day half-lives identified from isotopic analyses of the filter papers in addition to the < 8 day half-lives of the decay daughters of Radon-Thoron.
These data are presented in Table 1.
Gaseous Releases Argon-41 is the maj or 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 1981 was 7 51 E-01 curies.
This results in an annual average release rate of 1.01 E-08 pC1/cc as me;sured 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 117-119, 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 basis and presented in Table 2.
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 radioactivity concentrations were determined for each release.
There were 63 liquid waste releases totaling 1.86 E 06 gallons including diluents from the Nuclear Science Center during 1981.
The total radioactivity released for 1981 was 1.61 E-02 C1 with an average concentration of 2.29 E-06 pC1/ml.
Summaries of the I
radioisotope data are presented in Tables 3 through 15.
Radio-activity concentrations for each isotope were below the limits specified in 10CFR20 Appendix B.

!I Solid Radioactive Waste l
There was a total of 81 ft J of dry solid waste material l
packaged in elaven(11) 55 gallon steel drums for disposal during ig 1981.
These materials were transferred to the Radiological Safety 1 E Office, Texas License 6-448, for disposal.
This material consisted of laboratory glassware, irradiation containers, decontamination j
materials, and expendable protective clothing and equipment, e.g.,
paper, shoe covers, plastic bags and gloves.
This material con-tained Co-60, Ir-192, Cc-137, Zn-65, Ce-141, Mn-54, Cr-51, and Cd-109 with the total radioactivity being 2.53 E-02 C1.

RADIATION AND CONTAMINATION CONTROL PROGRAM Introduction The detection and elimination of radiation hazards is an integral part of the Radiation Safety Program at the Nuclear Science Center.
The radiation and smear survey programs con-tribute to the control and elimination of these health hazards.
This program is effective in preventing the spread of radio-active contamination, improper storage of radioactive 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 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 radio-active 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.
There were no unexpected radiation levels or improper exposures of radioactive materials detected during 1981.
These surveys revealed only background radiations at the site peri-meter fence.
Contamination Survey The Nuclear Science Center is routinely surveyed for radio-active contamination every week.
This program includes the collection, analysis and evaluation of approximately 250 smear samples and the decontamination of areas and stored materials with removable beta-gamma radioactivities of greater than 300 dpm/100 cm 2, I
III-22 I
PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science Center for 1981 were within the limits of 10CFR20.
The maximum exposure received by an individual for the year was % 1400 mrem.
It is expe; Led that this value will be reduced to less than 500 mrem for the next reporting period by revising certain procedures.
A total of approximately 11.8 MANREM was received for 1981.
More important, the exposures reflect an extended effort by all personnel to minimize and eliminate radiation exposures whenever practicable.
These exposure data becomes more significant when one considers that in addition to routine reactor operations, over 21,000 samples containing approximately 2500 curies of radioactivity were produced and processed at the Nuclear Science Center in 1981.
The whole-body exposure data for NSC employees and experimental personnel are presented in Table 21.
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 5,303 visitors to the Nuclear Science Center during 1981.
The maximum exposure 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 neutrone and 10 millirems for thermal neutron radiations.
