I:4TRODUCTIO?J The IJuclear Science Center is operated by the Texas Engineering Experiment Station as a service to Texas A&M 2
University.
Tne facility is available to the University, other educational institutions, governmental agencies, Z
and private organizations and incividuals.
Tnis report nas been prepared by the staff of the Iiuclear Science Center of the Texas Engineering Experiment
=
Station to satis fy the reporting requirements of USDOE Contract llumber EY-76-C-05-4207 and o f 10 CFR 50 59 The report coveru the period from January 1, 1978 through December 31, 1973.
2 The reactor utilization remained at a high level with the total number of irradiations, sample irradiation hours and total experiment hours comparing favorably with the previous reporting period.
The reactor was not pulsed during tne reporting p'riod due to a restriction on pulsing until tne fuel damage study is completed.
Plans for the installation of an operational full FLIP core continued with tne computer analysis of several core configurations.
In addition to increasing core life, the FLIP eore will provide additional irradiation capabilities for improved utilization of the reactor.

Facility Safety and Operational Improvements
'Jork Pla t fo rm for the Reactor Bridge An aluminum platform with rubber mat covering was attached to the weat side of the reactor bridge (see figure 2).
The worn plat form la used to perform tacks such as cample handling, fuel handling and Ieactor maintenance.
The plat form remains attached during bridge movement, thus providing access for all reactor operating positions in the pool.
Prior to the inctallation a plat form available only at the stall position required re mo val when the reactor was moved to the large pool section.
The new plat form hau improved reactor operation y
~
procedureu and narety.
Facility Locks R e - F.e y e d A new key cyatem was established for the !!3C facility to improve security.
The plan was simplified by consolidating ceveral individually geyed loega.
The new key plan was initiated by the IJ3C and the loexamith work performed by the Texas A&M University ke',
shop.
Puerto Rico FL1P /uel Identification The upp2r end fittings of the Puerto Rico FLIP fuel elements were modified to identify the elements as containing FLIP fuel.
A flat surface was filed on the tip of the end fitting.
This produces a sainny end appearance when viewed underwater from above as compared to a dull appearance for standard TRIGA fuel elements that are not filed.
The identification procedure is required by Technical Specification S.l.a(5).
Pool Level Alarm Circuit dailfication A pool level alarm light was installed on the reception room Pacility radiation monitor panel.
The pool level indication has a latching feature with a recet.
The alarm light was installed to aid in i, h e evaluation of emergene;/ conditionc.

A total of 418 square feet of laboratory and conference space was added.
B.
Improvements to Reactor Systems and Experimental Facilities Console Changes or Improvements Made During the Reporting Period 1
a.
The auxiliary alarm panel was modified to provide H
visual and audible signals for personnel control of l
the beam port No. 4 neutron radiography facility.
"C-2" circuits were installed for personnel control j-sample preparation room.
The auxiliary panel alarm lay-t of the lower research level and the neutron radiography out was improved by the grouping of alarms and the selection of audible alarms using a bell or a door chime.
Th alarm panel circuit was modified to provide a test oi all alarm lights.
A switch was added to provide i
" elected facilit3 " door open" audible signals to aid the y
second shift operations personnel in surveillance of the facility.
b.
A new reset panel was installed providing an improved layout of switches that are easier to identify and use.
The period ceram bypass switch was relocated to the rear w
of the log power instrument due to its infrequent use.
t 1
The ;onsole power reset switch was also moved to the rear
[
of *he console.
Separate switches were provided for a
test ing the main and auxiliary panalarms.
A fuel m
tem >erature scram reset switch was added to the reset
~
panel.
NI
=
c.
The dual linear measuring instrument (safety amplifier)
A g
was mod! fled to provide latching scram signals and resets for detector high voltage failure and high flux 7
y scram.
Prior to the change the scram indication did act latch in for display on the main panalarm.
If the
[i problem cleared itself the indication on the instrument
[
would also clear.
The meter faces for each channel were p
i-marked to indicate a.0% tant signal reading.

Operational Prablems and Solutions b
Replacement of Reactor Bridge Platform Jacks b
The four aclusor jacks used to lift the bridge yoke and 3
teactor frame structure were replaced.
The old jacks became difficult to operate and replacement of shaft thru3t bearings did not correct the problem.
It was determined by inspection that the lead screws on the Jacks nad experiencu excessive wear and the jacks should be replaced.

16 Pool Water meak During Removal of Boral Liner in Beam Port No. 4 The boral 1.n:r in the amall diarneter section of beam port do. 4 was remo vec. using an extended chlsel tool to cut through the k inch thicPaean of the boral.
During removal of the boral the tool utruc-the flanged end of tne aluminum beam port extennion tubu causing the flange to leak at the 0-ring seal.
The leak was umall but action was taken to prevent 1o30 of pool water froin the utall.
The pool gate was positioned and replace-n.e n t of the C_maged beam port extension was reviewed by the operations staff.
The pool atall was drained and a new beam port extenalon was installed.
0-rings were replaced on all beam port flangen and the seal on the primary water return flapper valve wau replaced.
The pool walls of the stall were cleaned and adjustmenta were made to the neutron radiography reflector.
After fillJng the pool and testing the atall, pool divers installed an extension to beam port No. 5 located in the large pool section.
1001 water losu was prevented during installation of the extencion by plugging the end of the beam port with a pneumatic pipe plug device and a backup seal provided by closure of the 0-ring aealed beam port anield door.
Replacement of bearings in the Primary Pool Water Cooling Pump The pump anart bearings on the primary pool water cooling pump were replaced due to overheating of the old bearinga.
A garden nose water supply was connected to cool the bearinga until replacement could be scheduled.
The bearing cooling procedure permitted continued operation of tim reactor through a ousy cenedule.
The bearings were replrced Ina the pump returned to normal operation.
Inatallation of Vibration Reducing Snubbers on Water System Gauges Gauget used to measure water precsures are often damaged by vibrationa from pulaating water preucures within the system.
Snubbera tnat reduce precoure curgeu were installed on gauges used in tne reactor pool water cooling system and recirculation oy o vem (to prevent damage to the gaugen).
The snubberc were very ef fective.

Badertscher, II -- Clinical Research Associate Dr. Dan !!igat ower -- Pro fe s sor Dr David M.
iload -- l'r o f e s s o r The main objective of this project was to develop a prostatic imagin6 agent with the dog as a model.
Our I
hypothesis was that Palosein, a copper containing super-oxide dismutase enzyme, could be used as a labeled scanning agent whien is s ele c t ive ly t a r;e n up by the prostate gland I
and externally imaged in neoplastic conditions.
To accomplish this, we attempted to excnange activated 6"Cu for the two copper atoms in the Palouein molecule, by adjusting the pH of the 0.1 molar codium acetate solution down to 3 7 for 30 I
minutes, and then neutralizing the pH back to 7.0 with sodium hydroxide.

Schweikert -- Professor, Chemistry Dr. David Moore -- A3sistant Research Chemist Dr. John McGinley -- Assistant Research Chemist Ms. Ann McGinley -- Jraduate Assistant Melinda Yulo -- Graduate Assistant Dr. John Crimenko -- Assistant Research Chemist The Center for Tract Characterization utilized the 1 Megawatt reactor and Nuc lear Science Center on a variety of research projects durir.g the past year.
The majority of these projects involved Instrumental Neutron Activation Analysis (INAA) for the determination of trace substances in a variety of matrices at the ppm and sub-ppm level.
Basically, the INAA wor < falls in three categories.
(1) Pollution, (2) Antnropology-Archaeology, and (3) Marine I
Life.
(1) Pollution.
(a) The CTC cooperated with NASA in the analysis of air particulate samples for 25-30 trace elements in an effort to identify sources of air pollution and establish baseline measurements.
(b) Vanadium and I
Barium meas urer.ents were nade on marine biota and ocean and river sedimento to obtain baseline concentration values prior to oil drilling operationn.
Similar measurements were also made to assi;t in the study of the baule geo-I chemistry of the.;e met 213.

Neff -- Radiological Safety Officer Joe Harville -- Graduate Assistant The purpose of this project is to determine if it is possible to measure the ver ical distribution in an ocean Z
core of fallout related rad )nuclides.
From this measured 7
distribution and the known yearly atmospheric fallout rate, it is believed that a correlation can be drawn which will allow a determination of the data of the cediment sample, as well as, an approximation of the rate of sedimentation.
Chemistry POTASSIUM I:s ZIRCONIUM SAMPLES Personnel Dr. A. Clearfield -- Pro fe s sor Gary Day -- Graduate Assistant The purpose of the work at the Nuclear Science Center was to determine potassium in samples of the inorganiz ion ex-
]
changer zirconium bis (mononydrogen orthophosphate).
These samples were obtained from calorimetric experiment whose interpretation require a knowledge of the load (or percent g
composition) of the solid phase.
Standard samples were prepared from zirconium pyrosphosphate and potassium biphthalate (KHC H 0g) in known mass ratios.
All standards and samples 8 4 were dried at 100 C for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, weighed into plastic vials 3
(N 0.1 gm each) and sealed.
Samples and standards were un irradiated for 1 minute, allowed to decay for 5 minutes and counted using detector number one on the Canberra Scorpio MCA 2000 System for 300 seconds.
Standards were then used to compute the radiation flux for each element required (Zr, Hf, K) and these fluxes were then used in the MASCAL I

The substituted products thus formed carried a large amount of residue energy.
The pressure dependence of the unimolecular decompositions of these subst itut ional producta has been investigated under a I
very wide range of pressure including the ase of large alumin-lu::. containers for low pressure studien.

Further studies on pressure effect and the analysis of energetics of these and other similar systems are in progress.
The reactions of recoil 31 S1 atoms formed by the nuclear 31 P(n,p)31 Si, have been studied.
In such transformation, systems, it has been shown that recoil 31 Si atoms will abstract either H from PH 3 or F from PF3 to give the corresponding silylenes, 31SiH 31 2 or SiF2 The reactions of the silylenes thus formed with various conjugated dienes are the major concern of this program.
It has been shown that these sily-lenes formed in the nuclear recoil system consist of about 20% singlet and 80% triplet.
The addition of silylenes in all of tnese forms will add to conj ugated dienes to give the corresponding silacyclopent-3-enes.
The relative reactivities 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.

Work involved mapping of uranium content throughout a South Texas mine, also examination for Uranium-material or straight Uranium content in clay.
2)
Release of U and TH from granitic rocks.
Granitic rock material representative of unweathered rock, weathered granitic rock from soil profiles developed in situ on parent granitic rocks, and granitic material transported by a local stream traversing granitic rock was sampled in order to char-acterize parameters upon which the distribution and release of U and Th during weathering and local transportation are critically dependent.
In addition to field reconnaissance and examination of the samples with standard petrographic techniques, all samples were analyzed by nuclear techniques.
Particle track analysis was used on thin sections of the granite to determine the pre-weathering distribution and I
approximate concentration of U among the constituent phases of the rock.
Gam:na ray spectrometry of natural decay products was used to determine U, Th, and K in the parent gran it e,
I soil profile material, and in the stream cediment.
Delayed-neutron counting was used to determine U in stream sediment cmr.ples, soil profile samples and size and mineralogic fraccions I

of those samples to better delineate phases critical to U and Th loss and transportation.
While Th favors accumulation in soil materials, U is seen to be mobilized early in weathering, with considerable loss from the granitic material to the ground water system.
In areas of favorable structure, this loss of easily-mobilised U from granitic rocks is known to have contributed to the formation of economic deposits of U.

With support from the Bureau of Land Management,
a method of extracting the Vanadium from the biota, and thus obtaining reliable data in the PPB levels, is being developed.
Oceanograohy UR ANIU:? IN ANOXIC SEDIMENTS ON THE GULF COAST Personnel Dr. William Sackett -- Professor Frederick Webber -- Graduate Assistant A worldwide increase in nuclear power dependency and a continual depletion of high grade uranium ores are resulting in the utilization of lower and lower grade uranium deposits.
For example candstones in the South Texas Coastal Plain with from 0.1 to 0.23 uranium are presently being mined.
In the future, hign 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 I
sedimentu (up to 0.01%).
Anoxic sediments along the Gulf I
I-7 Coast such as found in the newly discovered Orca basin and in various estuarine and near shor-environments may show similar or greater enrichments than thoae found elsewhere.
Thus, the goal 01 thiu worg is to determine uranium concen-trations in sedi: 2nts in various anoxi; environments along the Gulf Coast in ora 2r to provide the data base for the evaluation of anuxic Julf Coast marine sediments as future uranium sources-Nuclear E x ne> ring Personnel Dr. Ron H.u-t -- nosoelate i r o l e.s a u r Les Albert -- Gradu tte Acciatant MEASUREME.iTo 01< 31 P CONCEdiRA'IION PRODUCED BY NEUTRON TRANSMUTATION DUPING OF SILIr%

111-1 EIG'LUE!!f REllXE CLGHY Introduction Sunmries of radioactive effluent released frun the Nuclear Science Center for 1978 are included in thia apperv11x. Tnese data are presented in tabular fann ano includa atmospheric, liquid and calid waste releaces.
Particulate Heleacea a
Ihdioactive particulateu are nonitored at the base of the central exhaust ctack and suninarized on a nonthly basia. The annual average release rate was I
1.15 E-ll pC1/cc. Total radioactivity released for 1978 was 8.58 E-04 C1.
There were no radioicotves with > 0 day half-lives identified from isotopic analyses of the filter papers. Trece analycen revealed only the decay daugntern of Ibdon-Thoron. Itece data aru presented in Table 1.
Gaceoun Releases I
AIT;on-41 la the mJor gaseous errluent pro.luced and released at the Nuclear Science Center. Thic effluent is reasured by photopeak counting I
tne gaseous discharges in the central exnauat otack. Total argon-41 radioactivities releas x1 during 197c was 2 30 C1.
This reflecto a 20%
dectuase of radioactivities released in 1977 lhis reduction is the result of no reactor operationu utilizing the irradiation cell and an extended effort by experinenter personnel in the proper uae and operatica of the N3C pneunntic irradiation ayatems.
Ihese data are cuninarized on a renthly bacia and presented in Table J Ltquid Waste Releaseo Radioactive liquid effluenta are collected in 11guld 'cate holdup tanks prior to release frun t he confine, of the Nucle:u' Science Center.
Sample analyces for radicactivity concentrationa and radioicotope identification
(
were determined for each releane.
ihere were 31 11guld waste releases totaling 5.17 EOS c111ona frcm the :cclear 3clence Center during 1978.
The total radioactivity releaned for 1978 was 6.93 E-03 Ci with an I
average concentration of c,. 33 E-UU p C1/ce.
Ihiioicotopes were identified as 60Co, 5 8co, s yn, 6 5:n, 1921p, 12Hb, 57Co, 1 3 76,12 /Sb, and 24Na. Releases were below the limits sp;cified in 10CI7120.
Su:rarlea of these release data are presented in tablen 3-14.
Solid fudioactive '.nate a
There was 242 ft 3 of coll 1 waate nnteriala cenerated at the Nuclear Science Center in 17(8.
l.h i s w a a t t was tranuferred to the Ibdiological Safety Office Ibxas Licunae Na. 6-+40, for dic; ucal. The bulk of this I
b waste,191 ft was mixe:1 re i U :ao, -usi e! cer freo the ue-3 ndreralizer system. The reLuining C ft was in the form of paper, poly gloves, rags, and ccner expendable laboratory ite:T,.
Total radioactivity was 6.34 5-03 C1.
Hadioisotopec were ident irled au 1 2 "Cb, 1 9 21r, 51 Cr, 60Co, bSZn,1d2Eu,109Cd, 5 %, ud 57Co.

E;WIRO:E!hAL SURVEY PROGRAM
's Introduction
'Ihe envirorcental survey samples were collected in accordance with the schedules of tre cooperative surveillance program between the Texas State Departneni., of !!ealtn and Texan A&M University. Tnese samples were arnlysed j
for gross Emana and beta activities and isotope identification. Data from these samples rennined basically unchangpd from 1977 an1 reflect the continued use of rutention facilities and sample analysis for laboratory effluents prior r-to their release. Sample analysis indicate that the activities are remaining at normal background levels in the unrestricted environment.
The envirornental survey program was expanded in 1977 to 4".clude the neasurenent of integrated radiation exposures at the site boundaries. Tnese neasurements are nnde for a period of approximately 90 days using comercially ava11aole tiemoluminescent dosinnters (TLD's) of lithium fluoride chips in c, lass encapsulated bulbs. Tnese dosineters are provided and processed by Texas D2partment of IIealth, Division of Occupational :lealth and Radiation Control.
^
Ambient background for these neasurements is detemined from a control dosineter located southeast of Easterwood Airport approxirntely 800 neters east of the Juclear Science Center site. This location is at a right angle to tre prevailing southeasterly winds which occur a large najority of ' he tine on an annual basis.
Table 20 lists tre average exposure rate above ambient background per megawatt hour of reactor operation for a number of locations at tne E
site boualary. The nignest exposure points are at the middle north and E
northwest corner of the site boualary. Additionally, a dosimeter is located adjacent to tne radioactive waste storage building and the Instrument calibration range. Exposure data from this dosineter is not considered as a result of reactor operations but does reflect the maxirum site bouniary exposure of 141 7 micro R/hr. Tnis site bounda"y location is furtner protected from free acceJs to the 02neral public for an additional 100 meters of fenced Texas A&M University property.
A dosinnter at this location reveals only background radiations.
I Su:anaries of the environmentel survey prograrl for 1978 are presented in Tables 16-20.
