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 10 CFR 50 59 The reports covers the period from January 1, 1979 through December 31, 1979 I Reactor utilization continued to grow during 1979 with an increase in the total number of irradiations, sample irradiation hours, number of samples irradiated, and total experiment hours. Reactor operation of 85.71 Mw-days for 1979 was essentially the same as the previous year. The I reactor was not pulsed during the reporting period due to a restriction on pulsing until the fuel damage study is completed.
The installation of an operational full FLIP core was achieved during the reporting period. The full FLIP core provides increased core life and improved irradiation capabilities for experiments .

r III. FACILITY OPERATIONS A. Facility Safety and Operational Improrements NSC Employees Complete Fire Training Course f Several individuals from the NSC reactor operations group and l I
maintenance group completed a fire training course for nuclear reactor operators. This course was developed by the staffs of the NSC and the Brayton Fireman Training Field and was offered l
g through the Texas Engineering Extension Service. The one week g courses involved partici. pants from various nuclear power utilities across the nation. Thes. courses will be offered again in 1980.
The NSC now has employees trained in basic fire fighting to provide the necessary initial response to fires in those areas critical to reactor and plant operationo. i l
Improved Radio Communications to Handle Emergencies Radio communications between the NSC and the University j Communications Hoom has been upgraded by the installation on campus I of a radio frequency repeater system. The system utilizes coded transmissions that eccentially eliminate inverference from other I
radio networks in the area. Additional versatility was obtained by I the addition of a battery powered portable radio at the NSC. This replaces a base station unit previously in use. Telephone and radio remain the primary means of communications during the handling of emergencies at the NSC.
B. Improvements to Reactor Systems and Experimental Facilities Console Changes and Improvements
- a. New shim safety rod drive control units were installed in j the reactor console. The units provife an improved display
- 5 of the carriage movement and control r ~ positions and j utilize an improved switch design. The rod position
!g indication was converted from a 0-40 cm scale to a digital j display of 0-100%. The control rods can be repositioned i to within an indicated 0.1%. The rod drive switch function
) was modified to provide separate switches for rod up and rod down movement. The rod down switch was changed to a i momentary contact type and does not latch as in the i previous units.
- b. A new reset panel was installed to improve the display
- and the reliability of switches. This unit provides ig separate switches for acknowledgement of alarms on either j
the " Main Panalarm" or the " Auxiliary Panalarm".
function was added for the temperature scram and the a reset j magnet power reset switch was relocated to provide easier access to tne operator.
!I
14 r
L
- c. Individual shim safety rod drop switches were added to
[
- the console to improve procedures for calibration of control rods by the rod drop method. These switches p are located on the left side of the console on the L voltage supply panel. This panel is behind a door whio" helps prevent accidental activation af the switches.
- d. The air cooling and filter system for the reactor console was modified to reduce dust collection on instruments.in the console. The new system draws cool air from the building air conditioning duct, filters the air and then delivers it to the incide of the console. This creates o positive pressure in the console cabinets and air exits the lower portion of the rear doors. This is a considerable improvement over the old system which created a negative pressure inside the console cabinets resulting in un-filtered air being drawn across instruments through cracks and open panels on the console. The dust problem was eliminated by the new system.
New Core Loading I The first NSC TRIGA reactor loading containing all FLIP fuel was performed in November 1979 The loading was designated Core V and contained 83 elements with a total excess reactivity of
$2.90. This was not sufficient excess reactivity to maintain an I operational core and meet utilization requirements. The loading was modified by the addition of 4 FLIP elements. This loading was designated Core VI and contains 87 elements with a total I excess reactivjty of $5.73 Figure 2.
The Core VI loading is shown in Inct eased utilization was achieved by providing irradiation positions (flux traps) on the periphery of the core.
I These positions are vacant fuel bundle locations approximately 3" x 3" in cross sectional area. There have be>n no operational problems with the new core loading.
Reactor Bridge Yoke Wheel Lock A locking device has been installed on the crank wheel which 1 I operates the movable yoke on the reactor bridge. The crank wheel is used to raise and lower the reactor frame structure for re-positioning of the reactor. Following relocation of the bridge I
the yoke is lowered until the reactor frar.. rest firmly on the
- floor of the pool. The bridge yoxe lock is keyed the same as i the bridge rail movement lock.
Overflow Pipe for Liquid Waste Holdup Tanks f A four inch PVC pipe was installed connecting the tops of
! liquid holdup tanks #1 and #2. These 5,000 gallon tanks are
! placed in alternate service by manual valve control. When the ,
! tank on line to the sump pump reaches approximately 90% full it is 1 iE v Aved ff and the second tank in placed in service. Accidental ig k j

overflow of a tank in service is handled by the interconnection of the two tanks. The probability of both tanks being full at the same time is very small as the tanks are under a daily surveillance program checking for tank levels and draining requirements.
Lab No. 3 Pneumatic System The pneumatic system for lab No. 3 uranium analysis was up-s graded to an automated sample irradiation and sample counting system. In the near future an automatic sample loader and a system to automatically transfer the sample to storage after
~
counting will be added. The new system uses polyethylene tubing i of 1" 0.D. and 7/8" I.D. for the sample line. A new irradiator L was fabricated for positioning in the reactor core. The system was designed to utilize the existing pneumatic system programmer
~
located in the reactor console. A sample diverter was developed
_ for routing to the shielded detector system for counting. Air I cyclinders are used to position the diverter using a sequence of
~ signals supplied by the pneumatic system programmer. Similar signals will be used for operation of the automatic sample loader and the sample storage systems.
~
C. Operational Problems and Solutions
- l Demineralizer Resin Problems l The cation and anion resins of the mixed bed demineralizer
] have reached a very poor performance level and their replacement g) is planned for early 1980. To improve the performance until replacement it was necessary to treat the resins with a saltwater solution. This treatment resulted in improved separation of the resins for only one or two regenerations. At present the only way
~
to achieve a separation for regeneration is to backwash the resins
% for extended periods of time. The resins have been in service ~
for approximately five years and have operated at a capacity much r lower than expected. The replacement resins will be selected on the basis of their ability to provide easier separation and deliver higher capacity while maintaining high purity water.
Reportable Occurrence - Failure of an Experiment Scram Circuit On 15 June 1979 during surveillance testing of scram circuits, an experiment scram circuit failed to function properly. The s circuit is associated with the Beam Port No. 4 neutron radiography cave entry dool. This circuit provides a reactor scram upon entry if the reactor is positioned within 18 inches of the beam port target. The reactor was not operating at the time. The failure of the scram circuit was due to a malfunction of the " Experiment Scran Reset" switch on the reactor console. The switch failed to mechanically switch contacts. Dust was observed on the moving parts of the switch. The switch was cleaned and immediately functioned properly. Other switches on the reset panel were also I
17 ( cleaned to prevent possible malfunctions. The switch was tested daily for the next 5 days of reactor operation without a failure. This problem is not expected to recur due to a recent change { in the reactor console air cooling system as discussed in Section B of this report. D. Changes in Operating Procedures Amendment No. 7 to Facility License R-83 was approved pro-viding a change to the Technical Specifications which authorizes ( the irradiation of explosive materials in the neutron radiography facility. The subject of fire and subsequent damage related to the handling of explosive materials in the neutron radiography [ facility received considerable attention by the NRC. In the interest of industrial safety and the protection of equipment the NSC will implement a smoke detectar system. The system will provide a means of detecting smoke in the reactor cable tray area and the _ central exhaust system. 1980. This system will be in operation in early [ , The following changes to SOP's were reviewed and approved by the RSB during the reporting period: SOP Number { Subject I-A Definitions and Abbreviations ( Figure I-C-1 NSC Administrative Organizational Chart I-G Distribution and Binding [ II-A General Organization and Responsibilities Figure II-A-1 { Reactor Operations Administration II-C Reactor Startup [ Figure II-C-1(a) and (b) Pre-Startup Checklist Figure II-F-1(a) and (b) Daily Shutdown Checklist [ II-G Movement of Reactor Bridge II-I Reactor Core Manipulation II-M Response to Alarms [ Figure III-I-2 Semiannual Scram Circuit Test III-L Control Rod Drive Maintenance F L IV-E Irradiation Cell Experiments Figure IV-E-3 r L Checklist for NSCR Irradiation Cell F l v.

The most reactive experiment irradiated had a worth of -344 5 Pulse tests were not performed during the reporting period due to the non-pulsing restriction initiated on 1 October 1976. This restriction has been enforced since the discovery of damaged PLIP fuel elements ad-Jacent to the transient rod.

I-l DESCRIPTION OF PROJECTS UTILIZING THE NSCR A. Texas A&M University Veterinary Physiology 1 F TRACE ELEMENT CHARACTERIZATION OF ANIMAL DISEASES Personnel l Dr. Dan Hightower -- Professor i l David Hobson -- Graduate Assistant I Biological tissue samples were irradiated in an attempt to determine any relationship between trace element levels and various animal diseases. Elements of interest in the study included Na, Cl, K, Br, I, Cr, As, Cu, Mn, and Zn. DETERMINAL ON OF IODINE IN VARIOUS BIOLOGICAL MATRICES Personnel 4 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 1 on the possible detrimental effects of certain food colorings. Pigs are used as the experimental animal. I Veterinary Medicine DEVELOPMENT OF PROSTATIC IMAGING AGENT i i Personnel i 1 j Robert R. Badertscher, II -- Clinical Research Associate !
- Dr. Dan Hightower -- Professor l Dr. David M. Hood -- Professor l
The main objective of this project was to develop a prostatic
- imaging agent with the Cog as a model. Our hypothesis was that Paloseln, a copper containing superoxide dismutase enzyme, could j be used as a labeled scanning agent which is selectively taken up
! by the prostate gland and externally imaged in neoplastic conditions. ! To accomplish this, we attempted to exchange activated 6'*Cu for the two copper atoms in the Palosein molecule, by adjusting the pH l l
I-2 C of the 0.1 molar sodium acetate solution down to 3.7 for 30 minutes, and then neutralizing the pH back to 7 0 with sodium [ hydroxide. The supernate was passed through a G-25 Sephadex column and 1.0 ml fractions were collected for approximately one hour. [ Radiological Safety Office - Nuclear Engineering Department [ DETERMINATION OF NATURALLY OCCURRING RADIONUCLIDES IN COAL AND COAL RESIDUES Personnel [ Dr. R. D. Neff -- Radiological Safety Officer and Professor _ Joe P. Harvill -- Graduate Assistant Due to the increased utilization of coal as a heat source for the production of electrical energy, an assessment of the naturally occurring radionuclide concentrations in ash products is necessitated. [ From this assessment, the possibility and degree of radiation hazard from either stack emissions, or perhaps directly from the waste disposal areas, may be evaluated. In pursuit of this goal, the { delayed neutron counting facility at the Nuclear Science Center was used to determine the uranium fraction of the sample. Also,
~
analysis for various daughter products in the uranium and thorium chains was accomplished by use of the counting systems in con-junction with the Scorpio computing system. DETERMINATION OF NEUTRON ENERGY SPECTRUM Personnel
~
Dr. R. D. Neff -- Radiological Safety Officer and Professor Don Davis -- Graduate Assistant Currently, personnel monitoring for neutrons requires detailed [ knowledge about the energy spectrum of the neutron field in question. As part of a project to . determine the best method for neutron monitoring at the NSC, a measurement of the energy spectrum near
~
the NSC neutron radiography facility was done. This employed a Bonner's Sphere system and a specialized computer program for data unfolding. The results of this project will allow determination of the energy range which contributes most to l neutron dose. Subsequently, other projects will lead to the mos, appropriate neutron monitor based on response to the measured spectrum. l I l
i I-3 Chemistry TRACE ANALYSIS OF CEMENTS Personnel . Dr. Thomas Vickery -- Assistant Professor Gabrielle Harrison -- Graduate AssLtant 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 I 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 -- Profc sor I Dr. L. Kullberg -- Research Associate Using the NSC for activation analysis, isotherms for the ion-exchange of sodium-potassium-hydrogen in crystalline zirconium l phosphates have been determined. The phases formed during the exchange were also identified. 5 TRITIUM AND SILICON-31 PRODUCTION PROJECT l Personnel Dr. Yi-Noo Tang -- Professor Dr. E-Chung Wu -- Professor Dr. E. E. Siefert -- Post Doctorate Recoil tritium atoms, generates from 3He(nep)3H process I with thermal neutrons from the reactor, reacted with organic compounds such as C H 5F, C 2H5 C1 and C-CgHe to yield products either from abstraction or substitution. The substituted products thus formed carried a large amount of residue energy. I The pressure dependence 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 I stabilized) varied as a linear function of log P effective pressure, P The was calculated by takibh. into con-sideration the relatih,c,ollisional ocefficient of the component molecules in each system. Further studies on pressure effect i and the. analysis of energetics of these and other similar systems I are in progress. I m
i I-4 1 The reactions of recoil 31 S1 atoms formed by the nuclear transformation, 31 P(n,p)31Si, have been studied. I In such systems, it has been shown that recoil 31 Si atoms will abstract either H from PH 3 or F from PF 3 to give the corresponding silylenes, 31SiH 2 or 31SiF 2 The reactions of the silylenes I thus formed wi',h various conjugated dienes are the major concern of this program. It has been shown that these silylenes formed in the nuclear recoil system consist of about 20% singlet and I 80% triplet. The additipn of silylenes in all of these forms will add to conjugated dienes to give the corresponding silacy-clopent-3-enes. The relative reactivities of the butadiene, various pentadienes, and hexadienes are being studied and the I nature of a large steric effect observed in some of the addition reactions is under serious consideration. NEUTRON ACTIVATION FOR POTASSIUM IN METEORITES FOR 39Ar/40Ar DATING Personnel Dr. M. W. Rowe -- Professor Dave Aylmer -- Graduate Assistant By irradiating meteorite samples and standards, it is possible to determine the K, Ca, and K-Ar age of the samples. The analysis I 13 done with noble gas mass spectrometry. The 39K is activated and decays to 39 Ar which allows an accurate estimation of the K content. An estination of the 40 Ar level which decays from I 40 K, can also be made. Thus, the ratio of $9Ar/40Ar leads to an accurate calculation of the K-Ar age of the sample. Ca is included to correct for any interference with the K determination. Ages on the order of 4.5 x 109 years are expected. 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 resonable 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 b71ng an obvious source of combustible fuel, they are rich in uranium. \ I \ I
i I-5 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 I samples. Size-fractionation, 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 I 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 lignite. Geology MINE AND FORMATION DESCRIPTION PROJECTS Personnel Dr. Thomas Tieh -- Associate Professor Dr. Wen H. Huang -- Associate Professor Students working under the above faculty members performed various studies of the uranium concentration and distribution in I several different regions of Texas. Some of these were in areas where exploration and/or production of uranium is underway, others address regions where the potential for exploration is of interest. I The following did work of this nature using both the delayed neutron method for concentration assay and the fission-track technique for distribution analyses: E. Ledger (Ph.D) -

I-6 - 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 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. TRACE ELEMENT ANALYSIS OF "t710US GEOLOGICAL REGIONS Personnel Dr. Robert Scott - u essor I Larry Tiezzi -- Graduate Assistant Jim Garrison -- Graduate Student, University of Texas Nel Tyner -- Graduate Student, University of Texas A series of studies of several areas of the world have been done to determine rare earth and trace metal levels throughout various types of rocks. These include mid-ocean ridge basalts, I hydrothermally altered basalts, igneous rocks from the Llano region of Texas, Arizona basalts, and rocks from the Deep Sea Drilling Project in the Pacific Back-Arc Basin. Data obtained are being used to study existing geological models and develop additional models and descriptive techniques. Oceanography DETERMINATION OF TRACE METAL CONCENTRATIONS IN SURFICIAL SEDIMENTS, MACRONEKTON AND SPINY OYSTERS FROM THE SOUTH TEXAS TOPOGRAPHIC FEATURES STUDY Fersonnel Dr. B. J. Presley -- Professor Dr. P. N. Booth -- Research Ase)ciate Dr. S. Schofield -- Research Associate I Robert Taylor -- Graduate Assistant Der Duen Sheu -- Graduate Assistant 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 samples were collected as part of the Bureau of Land Management's Gulf of Mexico Topographic Features Study. Most came from the I vicinity of the East Flower Gardens Bank. The primary purpose of these analyses is to determine baseline levels of trace metals in the biota and sediments from these biologically important These data will I fishing banks on the outer continental shelf. be used to evaluate the impact which present and future oil and gas exploration and production may have on these potentially
s I-7 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 1300 ppm and 1100 ppm respectively. { URANIUM IN ANOXIC SEDIMENTS ON THE GUD COAST Personnel ( Dr. William Sackett -- Professor Frederick Webber--- Graduate Assistant {- A worldwide increase in nuclear power dependency and a continual depletion of high grade reanium ores are resulting in the utilization of lower and lower grade uranium deposits. For example, sandstones in the South Texas Coastal Plain with from [ 0.1 to 0.2% uranium are presently being mined. In the future, high uranium-bearing materials in the sea may become important economic sources of this valuable element. [ One potential source of uranium in the ocean is anoxic environments. Several studies have shown that there is more than { an order of magnitude uranium enrichment in anoxic sediments (up.to 0.01%). Anoxic sediments along the Gulf Coast such as found in the newly discovered Orca basin and in various estuarine and near shore environments may show similar or greater enrich-E- ments than those found elsewhere. Thus, the goal of this work is to determine uranium concentrations in sediments in various anoxic environments along the Gulf Coast in order to provide the [ data base'for the evaluation of anoxic Gulf Coast marine sediments as future uranium sources.

CESIUM. UPTAKE IN CORAL Personnel _ Dr. David Schink -- Professor Jill Pecon -- Graduate Assistant [ This experiment utilized Cs-134 produced at the NSC as a tracer in coral. During a cruise aboard the Research Vessel GYRE, corals were placed in plexiglass aquaria to which the cesium tracer had-been added. Every eight days, one aquarium was [- opened and the coral removed-for analysis. This involved digestion,- filtering, and counting. In this manner data was obtained concerning the incorporation of cesium from ambient hf waters into the tissues of coral.

*This work is a continuation of studies designed to measure the production of 31 P by irradiations of float-zoned silicon at
~ the NSC. The process is known as neutron transmutation doping. Measurements were made to calibrate the NSC facility so that ~ correlations between neutron fluence (irradiation time) and calculated dopant concentrations could be made. Work was also done on gallium-arsenide crystals. Animal Science I FLOW OF INGESTED FORAGE PARTICLES THROUGH THE G.I. TRACT OF CATTLE Personnel Dr. W. C. Ellis -- Professor John Snell -- Research Associate Carlos Lascano -- Graduate Assistant An experiment was conducted utilizing several different rare I earth radionuclides as flow markers of ingested forage particles through the gastrointestinal tract of grazing cattle. Isotopes used include 141 Ce, 169Yb, 147Nd. Ingested forage was collected from several surgically modified heifers grazing within university owned land. This material was then labelled with one radionuclide and introduced into each I animal's stomach. Collection of ingesta and feces was done, and these were prepared and analyzed or. a NaI(Tl) detector. From assay, information concerning particle flow was collected. PENETRATION MECHANISM AND DISTRIBUTION GRADIENTS OF SODIUM TRIPOLYPHOSPHATE (STP) 'N PEELED AND DEVEINED SHRIMP Personnel Dr. Gunnar Finne -- Assistant Professor Vick! Tenhet -- Graduate Assistant
I-9 ~ In a project sponsored by the National Shrimp Breaders Association, peeled and deveined shrimp were labelled with 32P to determine the distribution of the preservative STP af ter treat-ment. Shrimp were treated with .5% and 1% STP solution, frozen, ^ and sliced. Each section was counted on a scintillation detector to determine the distribution of STP from outside to inside. ~ Results showed that the STP tended to accumulate on the surface of the tissue preventing further uptake. At higher concentrations (5%-10%), prolonged treatment overcame the apparant barrier resulting in uniform distributions throughout the muscle. B.

L III-2 EFFLUENT RELEASE
SUMMARY
[ Introduction b ' Summaries of radioactive effluents released from the Nuclear t Science Center for 1979 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 1.39 E-11 uC1/cc. Total radio-activity released for the year was 1.03 E-03 curies. There were no radioisotopes with > 8 day half-lives identified frem isotopic analyses of the filter papers. These analyses revealed only the (- decay daughters of Radon-Thoron. These data are presented in Table I. ( Gaseous Releases Argon-41 is the major gaseous effluent produced and released [ at the Nuclear Science Center. This effluent is measured by photo-peak counting the gaseous discharges in the central exhaust stack. Total Argon-41 radioactivities released during 1979 was 2.41 C1. This results in an annual average release rate of 3 23 E-08 uCi/cc [ as mes',ured 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 1979) {' 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 II. [ Liquid Waste Releases Radioactive liquid effluents re collected in liquid waste holdup tanks prior to release from ;he confines of the Nuclear Science Center. Sample analyses for radioisotope identification and radioactivity concentrations were determined for each release. ( There were 44 liquid waste releases totaling 910 E 05 gallons in-cluding diluents from the Nuclear Science Center during 1979 The total radioactivity released for 1979 was 2 35 E-02 C1 with an [ average concentration of-6.83 E-06 uCi/ml. Radioisotopes were
-identified as Ir-192, Co-60, Mn-54, Co-58, Na-24, Zn-65, Cr-51, Cd-ll5, Ce-141, Br-82, Cd-109, Co-57, Cs-137, I-133, and Sb-122.
Radioactivity concentrations for each radioisotope were below the [. limits specified in 10CFR20. Summaries of these data are presented in Tables 3-13 r L r L
. ?.m w III-3 Solid Radioactive Waste
( There was 29.41 Ft 3 of dry solid waste materials packaged in 4 each 55 gallons steel drums for disposal during 1979 These materials were transferred to the Radiological Safety Cffice, Texas License 6-448, for disposal. This material consisted of [ Eu-152 contaminated soil and 5 each 14 inch sections of 3 inch carbon steel pipe doped with Co-60. These materials contained 2.43 E-01 ci of co-60 and 1.02 E-03 ci of Eu-152. These data are ( summarized in Table 14. Also, an additional volume of approximately 250 Ft 3 of dry solid waste materials was assayed for radioactivity concentration and radioisotope identification. These materials [ were packaged in 55 gallon steel drums and stored for future disposal. [ [ [ [ [ . [ [ [ [ [ E E r L. ~

III-18 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 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 1978 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 un-
~
restricted environment. The environmental survey program was expanded in 1977 to in- [ clude 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 background for these measurements is determined [ from a control dosimeter lccated 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 19 lists the average exposure rate above ambient back- [- ground for. a number of locations at the site boundary. The highest exposure points at the nortn and west location of the site boundary. Additionally, 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. reactor operations but does reflect the maximum site boundary exposure of 51 3 micro R/hr. This site boundary location is [ further protected from ?ree access to the general public for an additional 100 meters of fenced Texas A&M University property. A dosimeter at this location reveals only background radiations. Summaries of the environmental survey program for 1979 are presented in Tables 15-19 E E E n

L-III-23 r L RADIATION AND CONTAMINATION CONTROL PROGRAM. Introduction The detection and elimination of radiation hazards is an I integral part of the Radiation Safety Program at the Nuclear k Science Center. The radiation and smear survey programs con-tribute to the control and elimination of these health hazards. r- This program is effective in preventing the spread of radio-E active contamination, improper storage of radioactive materials, and unwarranted exposures to radiation. Radiation Survey r' 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 l 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 i p Nuclear Science Center Facilities and site boundaries are surveyed l L monthly with beta-gamma sensitive instruments. These measurements , are taken to determine proper storage and identification of radio- l y active materials and that visitor and routine work areas are free l of radiatien hazards. Additionally, radiation monitoring support is provided for the reactor operations and experimenter groups i to insure the safe handling of radioactive materials and control l I of personnel exposures. There were no unexpected radiation levels L or improper storage of radioactive materials detected during 1979 These surveys revealed-only background radiations at the site 7 perimeter fence. L Contamination Survey "~ L The Nuclear Science Center is routinely surveyed for radio-active contamination every week. This program includes the ~ collection, enalysis and evaluation of approximately 250 smear Le samples and the decontamination of areas and stored materials with removable beta-gamma radioactivities of greater than 300 dpm/100 cm 2. This program was effective in the elimination of [ contaminated areas and ascertaining that visitor and personnel 1 traffic patterns were free of radioactive contamination. l i u i m L,. l l - I - l 6 NM .
L { III-24 [ PERSONNEL EXPOSURES [ Radiation exposures to personnel at the Nuclear Science Center for 1979 were within the limits of 10CFR20. The maximum exposure received by an individual for the year was 1060 mrem. A total of 5.610 MANREM was received for 1979 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 11,000 samples containing 1050 cuties of radioactivity were produced and processed at the { Nuclear Science Center in 1979 The whole-body exposure data for NSC employees and experimental personnel are presented in Table 20. [ These data are presented in graded divisions as required under 10CFR20.202(a). The access control procedures for visiting personnel were effec-tive in preventing exposure to radiation. There were 4,029 [- visitors to the Nuclear Science Center during 1979 The maximum exposure to any visitor 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. E O w W W m W w m~ E
