INTRODUCTION
)
The Nuclear Science Center is operated by the Texas Engineer-i ing Experiment Station as a service to Texas A&M University and the State of Texas.
The facility is available to the University, other educational institutions, governmental agencies, and private organi-cations 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, 1980 through December 21, 1980.
Headtor 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 l
experiment hours.
Reactor operation of 91.13 Mw-days for 1980 l
shows a 7Ti increase over the previous year.
The reactor was not pulsed during the reporting period due to a restriction on pulsing l
until the fuel damage study is completed.
i A new core, designated as Core VI-A, was established during this reporting period.
This core was designed to increase the neutrcn flux on the east face, thus enhancing the performance of the new multiple rotisnerie irradiation device and the neutron radiography facility.
The radioactive materials handling area was totally redesigned during this past year.
This was done to improve the handling of radioactive materials and to reduce the potential for the spread of radioactive contamination in this area.
A maj or facility improvement to the domestic s'wer and storm sewers was begun.
These systems had been deteriorating over the past few years and needed repair.
Construction has begun on the project with an expected completion date in 1981.
A maj cr problem encountered this past year has been the high turnover rate of personnel at the Nuclear Science Center.
The loss of professional and technical personnel to industry has become a serious problem in trying to maintain a stable reactor operations l
st aff.
This is due to the high demand for experienced nuclear personnel and the considerably higher salary offerings made by industry.

Facility Safety and Operational Improvements i
Smoke j
Detector Installation I
Tne smoke alarm 3:/s tem at the lluclear Science Center was ex-(
panded from the one detector located near Beam Port #4 to seven l
detectors located throu.;hout the containment building and laboratory l
I building.
This was done in the interest of fire and industrial safety to update and protect against damage to vital components of the reactor and its support systems.
Smoke detectors are located in the following areas 1.
Beam ? ort #4 neutron radiography area.
2.
Inside the central exhaust duct system, l
3 Above both the north and south reactor console cable trays.
4.
Above the control room inctrumentation panel.
5 In botn neutron activation analysis laboratories outside the containment area.
All of these units produce an audible alarm from the detecV r itself as well as remote actio and /isual alarms in the control i
room.
In the future this watem will be connected into the security surveillance unit located in tne TAMU campus radio room.
Material Handling Area Renovation To facilitate the storage and handl
- of radioactive caterials i
a number of change:s were made or are scheduled to be nade.
These changes are shown in Figure 2.
The ma.jor change in the addition of a cold sample preparation area on the east end o f the material handling area next to to the Electronic Shop (See Figure 2).
A half wall was constructed to separate the two areas and a door was put in for access to the cold side of the MHA.
All other modifications as shown n Figure
- ere not completed at the end of this rFborting period.
B.
Improvements to Reactor Systems and Experimental Faciliules Console Chane;e n and Imcrovements a.
Remote indicatora for the water level in the three radio-active waste water tanks were installed in the control room auxiliary panel.
These instruments provide the operator with previously unavailable knowledge and provide for safer operation, thereby reducing the chance of possible tanks overflow.
In addition, high water le '/ e l indicators were also installed in the control room for both the primary and secondary sumps.

Reylaconent af Deminera11: m Beada I
The cation and anion recins of the mixed bed demineralicer had t
reached a.ery poor per formance level and had to be replaced.
The old recinc had b:en in aervice for.ppro xima tel:/ five years and I
had operated at a capacit:. i;uch lower than expected.
The replace-ment reains uelected pi tide for easier ceparation and increaced i

_R_e.nlacement of Carbo-Dur Filters l
i Tne performance of th: carbo-dur filtration system had been deteriorating over the pact few years and had finally reached the point to where itc operation was no longer naticfactory.
All th-filter materialc had been depleted to an extent that the filter actually rained the conductivity of the water ac it passed through.
As a result all of the ir:.erior filter materialc had i
to be replaced.
This included the activated charcoal and all four dradec o f gra /el.
Alco, the paint on the lower portion of the tankb interior had begun to flake off.
The tank was thorougnly cleaned and the lower section was repainted v;1th epoxy paint and I
cealer, before the filter materials were incertad.
Heat Exchanger Cleaninc During a vicual inapection of the heat e/; changer through the cite glasu a buildup of ccale deponits wac noticed on the outside of the utainleaa cteel U-tuben.
It was acaumed this buildup had cauced a clight decreace in the capacity of the cym bem to Pr+,ove heat from the primar:/ pool water.
An attempt was made to reduce a
the scale deposits by circulating a chemical called Duotrex, g
obtained from Certified Laboratoriec, which in designed to strip I
off scale buildup and mineral depocita and hac a special additive to aid in the cucpencion of the loosened depositc.
The h e a i. exchanger was isolated from the rect of the cooling system and water was circulated at a rate of 100 gal / min through I
j i
15 the shell side of the heat exchanger.
Tne chemical was then added and circulation was continued for 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> after the pH of the water reachad 1 5 The system was then flushed to rencve all chemienle,nd suspended deposits.
A final visual inspection I
indicated tlit the oL ?rved scale had been removed.
- However, l
no significant increase in heat trans fer was noted.
1 E. layed Heutron Counting Lab l
l Renovation of the celayed neutron counting uranium analysis i
lab was completed.
This system utilises an already existing pneumatic system to t l ann i'e r samples to and fcom the reacter.
In addition to the existing setup an automatic sample loader and sample storage shield were fabricated, and a scanner / counter / printer system l
was added to the system.
I With these additiens and improvements the lab is now operational in the fully...utomatic made.
.ultiple Rotinnerie Irradiation System Due to an increased demand in rotisserie irradiation space a device has been designed and fatticated which will handle up to four ro"isseries.
This device was designed to be used on the west face of the reactor, thus allowing the simultaneous use of all other irradiation facilities.
The device utilises an electric matcr to drive the system, which is mounted on the reactor bridge.
This motor is connected to the rotisserie drive by an aluminum l
driv" shaft which is suspended from the reactor bridge.
This l
system is used primarily for irradiation of 1 week duration or longer l
l New Core Loading i
The primary purpose
or t his change was to increase the avail-able flux on the east face of the reactor.
Core VI (See Figure 3T
'tas modified to Ccre VI-A by moving the fuel bundle from the D-7 location into the F-5 notch.
'ine new loading is sho'.;n in Figure U.
Tests were conducted which confirmed an increase in the neutron flux on the east face.
Tests also indicated that this change caused the flux chape to flatten.
Both of these were desirable i
I effects and the core was declared operational.
However, this core was only operated as needed for neutron radiography.

I An analy313 of the damaged tower ce"ealsd that the mounting for i he fan tranamission
'? ailed caucing the fan blades to rip through the w.'Is cf the fan 'olade housing.
The fan blades broke awa:, from the,;ransmission hub when they made contact with the I
,ecoden fan housing.
The fan assembly and the fan housing were
'g damaged beyond repair.
The fan assembly had been recently g
inspected by a factor', representative and found to be in r.eed o f repair.
imp a i r partc were on order at the time of the i
incident but.hipnent wac not acheduled untf1 early June 1930.
l 5
The reactor.vaa operated on a reduced schedule until Ma./ 21, l
1930.ehen a t mporary ran acaembly was placed into service.
The i
temporary far installation provided approximately three-fourtha (3/4) the ori;inal cooling capacity, which was adequate for the normal achedule of reactor cperaticns.
The temporary ran as sembl',
conaicted.cf 4 fan unita mounted in a 2 x 2 array on a wccd beam l
support stro^ture <thich cpanned the circular openint; at the top uf th" cool;.c tower.
Each ran unit consicted of a 54" 7 54" steel frame nwcini" alth a R horsepower motor and direct drive fan blade assembly.
The original design rep]2coment was installed and put in ce vice 9-2-80.
The temporary fan as.~mbly has been retained for emergency ute.
Starr E em and i'an te' eat er Jy ct ema, The ctorn drainage cyatem at the Nuclear Science Center has exparienced long-term aubaurface erosion along the out fall line.
This has reaulted in the total failure of the system to perform its design function.
/ccociatad with thic problem is the location 0: the radioacti~ waste holdup tanks which are directly above this out fall line.
Theac tanks have began to cettle due to this sub-curface erosion, and must be relocate' A atudy of tne storm and canitary sewers was made and a ecn-tract was awn.raed to Binkley and !!almec, Inc., to repair these syctems.
l Thir nroj e ct involved the design and ccnctruction of an adequate l
outfall structure, relocation of the radioactive holdup tanks, and l
2scociated dict. cork to remove all subcurface erocion pockets.
This ucrk chould be
.pleted by September 1931.

Siefert -- Post Doctorate hecoil tritium atoms, generated from 3pe(n,p)3H process with thermal neutrons from the reactor, reacted with organic compounds C H Cl and C-CgH to yield products either from C HsF, such as 2 5 g
2 abstraction or substitution.
The substituted products thus formed carcied a large amount of residual energy. 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 prese'-e condition, and (2) the fraction decomposed (or stabilized) varied as a linear function of
I I-3 The effective pressure, F,
was calculated by taking l o g P,b:k,s.
into d ideration the relative collib[o,nal coefficient of the component mole.cules in each system.
Further studies on pressure e f fec t and the analysis of energetics o f these and other similar systern are in progress.
The reactions of recoil 31 Si atoma 7ormed by the nuclear 31 P ( n, p ) 31 Si, have beon studied.
In such systems, transformation, it has been shown that recoil 3151 atoms will abstract either H i
from PH o." F from PF to give the corresponding silylenes, 3
3 31c4H or "lSiF The reactions of the silylenes thus formed with 2
2
/arious conj ugated dienes are the major concerl. of this prcgram.
It has been shown that these silylenes formed in the nuclear recoil system consist of about 200 singlet and 80% triplet.
The addit'on lI l
of silylenes i:. all of these for:a will add to conjugated dienes to give the corresponding silacy-clopent-3-enes.
The relative l
reactivities of the butadiene, various pentadienes, and hexadienes l

in some of the addition reactions is under serious consideration.
l NEUTRON ACTIVATIO:. FOR FOTASSIUM IN METEORITES FOR 39Ar/40Ar DATING Personnel Dr.
M.
W.
Howe -- Pro fe s s o r Dave Aylmer -- Graduate Assistant By irradiating metecr'te samples and standards, it is possible to determine the E, Ca, anu K-Ar age of the samples.
The analysis is done with noble gas mass spectrometry.
The 39K is activated and decays to 39Ar which allows an accurate estimation of the K content.
An estimation of the 40 Ar level, which decays frcm h,
can also be made.
Thus, the ratio of 39Ar/40Ar leads to an 40 I
accurate calculation o f the K-Ar age of the sample.
Ca is included to correct for an interference with the K determination.
Ageo on the order of 4.5 x 109 years are expected.

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 gcal 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 l
samples.
Sjze-fractionation, density-bradient fractionation and fl~tation will be some o f 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.

Industrial Training Programs In addition to the activities described above, the NSC through l
the Texas Engineering Extension Service has embarked on a program to develop a number of training courses for industrial organisations.
These are primarily oriented toward nuclear power plant and medical re march pers^nnel.
A description n~ the courses is preJented below.
FIREFIGHTlI.'G FOR MudLEAR POWER PLANT PERSONNEL i
1 Instructors Mr Paul Hanneman, TEES Mr. Gene Bates, N3C Mr. Een Walker, NSC This course uses the extensive facilities at the Erayton Fire-man Training field for practical, hands-on training in the types of fice situations which nicht be faced by nuclear power plant fire brigades.
Usually the brigade members uave had little or no such experience.
This is enmbined with the expertise and use of the NSC to present the particular problems of firefighting with radiat'on or radioactive contamination present.
A combined fire / radioactive contamination exercise is conducted as a final exam.
One course was hold in 1980 with representatives from 8 power utilities.

III-2 EFFLUENT RELEASE
SUMMARY
I Introduction Summaries of radioactive effluents released from the Nuclear Science Center for 1980 are incluaed 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 summarised on a monthly basis.
The annual average release rate was 8.67 E-12 pC1/cc.
Total radio-I activity released for e year was 6.47 E-04 curies.
There were d day half-lives identified from isotopic 3 radioisotopeu with >
analyses of the filt?r papers in addition to the < 0 day half-I lives of the decay daughters of Radon-Thoron.
These data are presented in Table 1.
l l' '.s e o u ' Releases Argon-41 is tue maj or gasecus effluent produced and released at the I;uclear Science Center.
This effluent is measured by I
counting the Argon-41 photopeak in the gaseous discharges of the central exhaust stack.
Total Argon-41 released during 1980 was i
7 67 E01.
This results in an annual average release rate of (E
1.03 E-08 nCi/cc as measured in the central exhaust stack with no g
lilution factors applied.
Applying the dilution factor of l
50 E-03 allcwed at the uite boundary (as determined, SAR, pages l
117-119, June 1980) results in radioactivity concentrations of
<l5 of the limits specified in 10CFR20, Appendix B, Table II, Column 1.
These data are summarised on a monthly basis and presented in Table 2.
l Liquid Waste Releases i
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 concentrationc were determined for each release.
There were 66 liquid waste releases totaling 1.14 E 06 gallons including diluents from the Nuclear Science Center during 1980.
The total radioactivity released for 1980 was 2 35 E-02 Ci with
,(
an averaga concentration of 9 90 E-06 pC1/ml.
Radioisotopes were
'E identified as Ir-192, Co-60, Mn-54, Co-58, Na-24, Zn-65, Cr-51, Nb-95, Mn-56, Ph-214, Cd-ll5, Ce-141, Br-82, Co-57, Cs-137 and Sb-122.
Radioactivity concentrations for each radioisotope was below the limits specified in 10CFRPO.
Summaries of these data are presented in Tables 3 through 15
-n
.II-3 i
Solid Radioactive Waste I
There was a total of 125 ft 3 of dry solid waste material packaged in seventeen (17) 55 gallon steel drums for disposal during 1930.
These materials were transferred to the Radiological Safety Office, Texa, 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, c':-137, zn-65, Ce-141, Mn-54, Cr-51, and Cd-109 with the total radioactivity being 1.74 E-02 C1.
These data are in Table 16.

III-20 ENVIRONMENTAL SURVEY PROGRAM Introductio_n The environmental survey samples were collected in accordance with th" schedules of the cooperative surveillance program between the Texas 9 tate Department of Health and Texas A&M University.
These samples were analyzed for gross gamma and beta activities anu isotope identification.
Data from these samples remained i
bacleally unchanged from 1979 anJ reflect the continued use of retention facilities and sample analysis for laboratory effluents prior to their release Sample analyses indicate that the l
activities are remaining at normal oackground 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 bourdaries.
These measurements are made for a period of approximate 1 - 90 days using commercially available thermoluminesce.nt dosimeters (ILD's) of lithium fluoride chips in glass encapsulate l
bulbs.
These dosimeters are provided and processed by Texas Department of Healtn, Division of Occupational Health and Radiation i
Control.
Ambient background for these measurements is determined from a control dosimeter located southeast of Easterwood Airport l
approximately 800 meters cast of the Nuclear Science Center site.
l This location is at a right
'gle to the prevailing southeasterly I
winds which occur a large majority of the time on an annual basis.
Tablo 20 lists the average exposure rate above ambient back-ground for a number of locations at the site boundary.
The highest exposure points at the north 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 expo ure of 54.0 nicro H/hr.
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 proper ty.
A donimeter at this location reveals.:nly backEround radiations.
Summaries of the environmental survey program for 19Pd are presented in Tables 17-19 for gross beta activity.

-Introduction i
I k
l The detection and olimination of radiation hazards is an integral part of tle Radiation Safety Program at the Nuclear i
3cience Center.
The radiation and smear survey programs con-l j
tribute to tne control End elimination of these health hazards.
Thia program ic effective in preventing the spread of radio-active contaninatlon, inproper s t ora r;e of radioactive materials,
and unwarranted exposureo to radiation.
I i
H tdiation c urvey The Nuclear Oclence Center use; an area radiation monitoring I
syntum con inting. of nine (9) detector channels located throughout l
1 th" Reactor ar.d Laboratory Buildings.
This syctem is equipped.d t h
(
alarm aettingo and remote readouts in the control and reception rooma.
Radiation '.evelt and opeiational checks ara recorded on a daily ba313.
Thic nyntem functionc as a radiation safety monitor i
for tne early detection of impending radiation hazards.
The l
- uclear 3cience Center Facilitico and site coundaries are curveved l
monthly with bett -gamma noncitive instruments.
Thece measuremeits are tagen to determine proper atorage and identification of radio-active materi11n and that vicitor and routine work areas are free ilation Lazarda.
Additionally, radiation monitoring cupport of in
/ided for the reactor operations and experimenter groupa 1
to inaure the safe handling of radicactive materials and control of personnel exposuren.
There were no unexpected radiation levels or improper exposures of radioactive materials detected during 1980.
These surveyu revealed only background radiations at the site perimeter fence.
Contamination Jurvey_
The Nuclear Science Center is routinely s ur ve:/cd for radio-active contamination every week.
This program includes the collaction, analysis and evaluation of approximately 250 smear samplea and the decontamination of areas and stored materials
.zith removable beta-garrma radioactivities of greater than 300 dpm/100 cm2 Thic program was effective in the elimination of contaminated areas and ancertaining " hat visitor and personnel tra f fi c patterna were free of radioactive contamination.

III-26 PERS0!HIEL EXPOSURES Radiation exposuren to personnel at the lluclear Oclence Center for 1980 viure within the limita of 10CFR20.
The maximum exposure received by an individual for the year was 1200 mrem.
It is i
expected that thic value will be reduced to less than 500 meem for the next re,;rting period by revicing certain procedures.
A total of 6.490 M;NnEM was received for 1980.
More important, the exposures reflect an extended effort by all personnel to minimize and eliminate radiation exposures whenever practicable.
These exposure data becomes more cignificant when one considers that in addition'to routine reactor operations, over 11,000 camples containing 1050 curiec of radicactivity were p;oduced and processed at the I!uclear Science Center in 1980.
The whole-body exp3aure data for IJSC employees and expe'imentel peraonnel are procented in Table 21.
Th'se data are presented in graded divisions E7 required under 10CFR20.202(a).
Tne acceus control procedures for visiting personnel were effec-tive ir. preventing exposure to radiation.
There were 4,198 visitors to the I;uclear Science Center during 1980 The maximum exposure to any visitor as determined by film badges was less than the minimum meanurable quantitles.
These values are 10 I
nillirema for X or gamma, 40 millirema for hard beta, 20 millirems for fact neutrons and 10 millirems for thermal neutron radiations.
