1 I. INTRODUCTION The Nuclear Science Center is operated by the Texas Engineering Experiment Station as a service to the Texas A&M University System and the State of Texas. The facility is available to the University, other educational institutions, governmental agencies, and private organizations and individuals. 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, 1982 through December 1, 1982. Reactor utilization continued at about the same pace as the
. previous year with a slight decrease in the total number of . irradiations, number of samples irradiated, and total experiment hours. Reactor operation of 93.3 Mw-days for 1982 represents approximately an 11% decrease over the previous year. There was, however, a significant increase in the number of sample irradiation hours primarily due to a smaller number of experimenters irradiating an extensive number of samples when compared to the previous reporting year. The reactor was not pulsed during the reporting period, but the fuel damage study was completed and preparations are being made to pulse in 1983 Core VII-A was established during this reporting period and was used throughout most of 1982. This was only a minor modifica-tion to Core VII which combined the neutron sources into one canister allowing an additional pneumatic receiver to be placed in the core. Core VIII was established in December, 1982 and involved the installation of the transient rod in preparation to reinitiate a pulsing program for the NSCR.
Several major facility modifications and improvements were completed during the past year. The machine shop relocation begun in 1981 was completed this past year. In addition the reactor control room was remodeled, and work began to upgrade the demineralizer room by repainting, repairing leaky valves, and
-resurfacing the floor. A new Beam Port #4 water shutter was installed to reduce personnel radiation exposure during experi-mental use, and the evacuation horn system was modified to allow the air horns to be silenced from the reception room once all personnel have been accounted for. Because of leakage and corrosion problems associated with the exhaust system for the chemistry lab and sample handling cell, this system was replaced with a single high capacity blower and an acid / caustic neutralizing filter. Also, an increased need for a high flux rotisserie resulted in the installation of a new rotisserie motor to be used in the reactor west face notch.
2 LSeveral operational problems occurred'during 1982 some of which resulted in a loss of reactor operating time. The waste storage tank leak reported in 1981 was corrected with the
. purchase and installation of a new fiberglass tank. A new high velocity' raw water stirrer system has also been developed for the waste storage tanks due to frequent failures of the old mechanical system. There was also an extensive number of electronic problems sssociatad with reactor systems which had 'to be corrected throughout the year.
Administratively during 1982 Donald E. Feltz became Acting Director and assumed the duties of former Director, Dr. John D. Randall who was reassigned to the Nuclear Engineering Department at Texas A&M University. In addition a loss of experienced personnel in supervisory and management positions resulted in having to acquire and to train new individuals for these key positions. Efforts are, however, underway to stabilize the staff and reduce personnel turnover.
3 II. REACTOR UTILIZATION A. Utilization Summary Utilization of the NSCR during the reporting period is shown in Figure 1 and Table I. Figure 1 presents reactor operation from January 1969 through December 1982. During the present reporting period the NSCR was used by approximately 1,200 students and 25 faculty and staff members representing 13 departments at Texas A&M University. In addition, more than 350 faculty and students from 12 other educational institutions used the facilities, and 6,280 visitors were registered during 1982, including 14 high school groups. A total of 23 non-university organizations had programs that were dependent upon the NSCR. During twenty years of operation, the NSC has provided services to 36 departments at Texas A&M University, 102 other colleges and universities,'75 industrial organizations, and 20 federal and state agencies. (See Appendix IV and V for listings). B. Utilization by the Texas A&M University System During 1982. the following personnel

1 14 - III. FACILITY OPERATIONS A. Facility Safety and Operational Improvements
' Machine Shop Relocation IAs reported in the'1981 annual report, continued expansion at the:NSC. involved ~the addition of a new machine shop adjacent to the storage shed. The shop relocation was completed in January, 1982. . Reactor Control Room Modifications ,
In March, 1982'remodeling of the reactor control room was completed. This-included. repainting, carpeting, providing new
. chairs-for operators, and installing a new reactor schedule board.
Evacuation Horn System Modification In March, 1982 the evacuation horn system was modified to allow the horn to be disabled using controls in the reception room after all personnel have been accounted for following evacuation of the facility. This.was done in an effort to reduce noise and confusion { during emergency evacuations. 'As seen in Figure 2 a solenoid operated isolation valve was installed, and a bypass line was
'provided should the solenoid fail to function properly. The bypass
-valve is operated manually behind the control room panels. lit should also be noted that since the solenoid valve is normally open, a loss of power to the facility will only result in an inability
.to silence the air horns from the reception room.
Upgrading of the Demineralizer Room During August, 1982 reactor operations personnel repainted the demineralizer room and its associated piping. In addition leaking
. valves were repacked, and the acid pump used for regenerating the ion exchanger.was remounted on the wall. The concrete floor has deteriorated over the years due to exposure to acid, and work has now begun on resurfacing:and providing for better drainage. This work is expected to be completed in 1983 I

16 B. Improvements to Reactor' Systems and Experimental Facilities New Core Loadings i
' Core VII-A (see Figure 3) was established January 6, 1982.. .This new core was only a minor modification to Core VII in that the neutron- sources _ were relocated within a single tube in grid location E-2 and an extra pneumatic receiver was positioned in D-2. This-core was used throughout the year until' December.3, 1982 at which timeLCore VIII (Figure 4) was. established. As can be seen this change consisted. simply of the . installation of. the transient rod
-in-preparation for reinitiating pulsing operations of the NSCR.
Addit' ion of West Face Rotisserie Motor Due to an increased need for a rotational irradiation ~ device within a high flux area a new rotisserie motor assembly was installed-for use with the B-5 grid position. A smaller rotisserie designed'to' rotate within a 3" x 3" core notch is used-with this 7 system, and a remote' motor control switch and a power ~"0N" light have been installed in the control room. Beam Port #4 Water Shutter > In May, 1982 a new Beam Port #4 shutter system was installed
- and tested. This new beam port extension (see Figure 5) has the capability of being flooded with water which serves as 'a neutron /
gamma shield. Water: evacuation is accomplished using low pressure air and solenoid operated valves. Water level is determined using a float-switch as incorporated in the shutter design, and. digital indication of. the beam port condition is 'provided in the beam port #4-sample prep. room. This new shutter system reduces. personnel radiation when handling film cassettes between
' irradiations.
- Installation of Pneumatic System Controller ~for Shell Laboratory As discussed in the 1981 annual report a new lab was established for-the7Shell Development Company. In March, 1982 the pneumatic - transfer system for this lab was modified such that a controller
= separate from the control room central unit was available for use.
A' permit switch was installed in the. control room, but the experi-menter has the capability to. establish his desired timing sequence. In addition to this change in the laboratory the south pneumatic station on the mechanical chase level was modified such that the Shell lab has its own' separate piping system. Modification of the Chemistry Lab and Sample Handling Cell
- Exhaust System Because.of leakage and corrosion problems associated with the exhaust system for the chemistry lab and sample handling cell, the

q 20 system was replaced with a single high capacity blower and an acid / caustic neutralizing filter. The new system (Figure 6) was designed such that a negative pressure is maintained in all lines upstream of the blower. The exhaust from the chemistry lab hood is. drawn through a chemical filter prior to discharging to the central exhaust system, and a damper box is installed downstream of the filter to adjust for proper flow rates from the chemistry lab and sample handling cell. Negative pressure in the line from the sample handling cell has been achieved with the elimination of the small suction blower previously used. In addition there will be a direct connection from the bridge to the blower for handling future venting requirements for the pneumatic system. C. Operational Problems Waste Storage Tank Beolacement As reported in the 1981 annual report work was begun on the relocation of the radioactive waste storage tanks to a new slab. Tank #1 was found to have a leak, and following a decision not to repair the tank, a new fiberglass tank was installed in October, 1982. The new tank has a volume of 12,500 gallons and was declared operational in November, 1982. Modification of the Waste Storage Tank Stirrer System Because the previous motor driven stirrer system for the waste storage tanks had experienced frequent failures, a new system as shown in Figure 7 has been developed. This high velocity raw water system consists of a flexible hose with a quick disconnect and a distribution header within the tank. The hose is dis-connected at all times when stirring is not in progress to minimize the possibility of contaminating the raw water system. In addition a siphon break hole is provided at the high point of the raw water system within each tank to prevent accidental siphoning. Electronic Problems Associated with Reactor Systems Equipment age resulted in a significant loss of operating time On two occasions frayed for the reactor during the past year. and deteriorating cables resulted in short circuits and excessive electronic noise within the console. A large amount of reactor operating time was lost in October,1982 due to a series of dropped rods occurring because of a weak armature magnet for the shim safety control rod and electronic noise being generated by a faulty high voltage power supply in the Safety Channel instrument. Because these two problems occurred simultaneously and were intermittent in nature, locating the cause proved to be very difficult. Efforts are being made to carefully inspect and locate these problems by implementing a surveillance program to reduce failures which could occur as the components continue to age.

23 Reportable Occurrences Failure of the Linear Power Channel to Respond During Reactor Startup On February 5, 1982 during the initial reactor startup of the day, it was noticed that the linear power channel was not responding. Rod withdrawal was terminated with the shim safety control rods at approximately 40% and reactor power less than 1 watt. The detector high voltage switch was found to be in the off position, and a reactor shutdown was initiated. The reactor supervisor restored power to the detector, and the reactor was started up to 1 Mw with no further problems. Although the operator observed proper detector
- voltage during the prestartup check, the switch was apparently inadvertently turned off prior to startup. Normal subcritical multiplication was observed on the Log Power Channel but it was not until the reactor approached 1 watt that the operator noted no response on the linear channel.
Failure of the Log Channel Rate Meter During a Reactor Startup On July 22, 1982 during the initial reactor startup of the day it was noticed that the log power channel rate meter was no longer responding. The reactor was shutdown, and following a cleaning and inspection of various switch contacts normal meter response'was observed. However, the meter failed a second time during the subsequent reactor startup. A further cleaning of amplifier boards restored normal operation, and a third reactor startup was performed with no further problems noted. The inter-mittent nature of the problem made it difficult to pinpoint the exact cause of failure. However, the instrument has since been observed closely and no further failures have occurred. Failure of a Fuel Temperature Thermocouple During Reactor Operation On September 28, 1982 erratic readings were noted of the fuel temperature indicator while the reactor was operating at power. The reactor was shutdown, and on Setember 29, 1982 a different instrumented fuel element (IF) was connected to the Fuel Temperature Channel. After approximately twelve hours of operation erratic readings were once again observed and the reactor was shutdown. A new IF was prepared and installed in the core on October 1, 1982 and has operated natisfactorily since that time. Reactor Operation in Excess of Licensed Power Level i On December 4, 1982 following a core change to establish Core VIII a power calorimetric was performed and indicated the reactor was operating lower than the indicated power. Since all pro-cedural requirements and initial conditions had been adhered to and the data appeared to be correct, the reactor power detectors
24 werefrepositioned such that the calculated actual power-and indicated power agreed.. A.second calorimetric performed on December 10, 1982 indicated'that reactor power was.actually much higher.than indicated,.and a. series of additional calorimetrics were completed.during.the following week to confirm -the results. Based on these results,'NRC' Region IV was' notified on December 17, 1982, and it was later decided that reactor power'may have
.been as'high as~1.37 Mw on December 6, 1982 and 1.23 Mw from December.7, 1982 to December,9,11982. A thorough investigation into the. calorimetric of December 4 indicated that an improper ice bath for.the reference temperature had been prepared causing the large. error-obtained.- .The ice bath prepared with too g little water. experienced a temperature change of approximately 5 F over a ltwo hour period resulting in a 30% error. Operators have now-been trained in the proper method for ice bath preparation, and until the calorimetric procedure is thoroughly reviewed an
" interim procedure limits the amount of reactor power increase by. detector adjustment at any one time to no greater than 10% of i the measured power. Security Incidents There were two incidents pertaining to security requirements at the NSC during-1982. However, due to public disclosure restrictions these, will not be addressed in this report. It should be noted; however, that neither case involved an item of noncompliance. D.

Unscheduled Shutdowns A total of nineteen unscheduled shutdowns occurred during 1982. As can be seen a large number were electronic in nature due to equipment age. The' unscheduled shutdowns can be arranged in the following_ categories: Cause of Shutdowns Number of Shutdowns Building power loss 6 Operator error 3 Electronics 10 F. Reactor Maintenance and Surveillance
- 1. A calibration of the fuel temperature measurigg changel was
- performed on 1-7-82. The LSSS was set at 525 C (975 F).
- 2. A channel check of the fuel element temperature measuring channel was made daily by recording the fuel element temperature and the pool water temperature prior to reactor startup.

- 4. The reactivity worth of all experiments was either estimated or measured, as appropriate before reactor operation with the experiment. The most reactive experi-ment ~ irradiated had a worth of $.65.
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 FLIP fuel elements adjacent to the transient rods. However, there are plans to pulse in 1983 and the transient rod was installed in December with the establishment of Core VIIT.

. SEDIMENTS, MACRONEKTON AND SPINY OYSTERS FROM THE SOUTH TEXAS TOPOGRAPHIC FEATURES STUDY Personnel Dr. B. J. Presley -- Associate Professor Dr. P. N. Boothe -- Research Associate Fred Fenner -- 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 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 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 produc-tion 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 1 300 ppm and 5 100 ppm respectively.

Recoil' tritium atoms,-generated from 3He(n,p)3H process with thermal neutrons from the reactor, reacted with organic compounds such as C 2 HsF, C 2 Hs cl-and_C-C 4He to yield' products either1from
. abstraction or substitution. The-substituted products that formed-carried : a -large . amount of residual energy. The pressure dependence
;orithe unimolecular decompositions of these substitutional products
'has been investigated under_a very wide range of pressure including
'the.use of;1arge aluminum containers for-low pressure studies. .The:
results' indicated that (1) essentially all. excited molecules will l decompose under a very low pressure condition, and.(2) the fraction-
. decomposed (or stabilized) varied as a linear function of. log Pgpp.
The effective pressure consideration P~bI, the relat19 was calculated collisional by taking coefficient intocomponent of-the molecules in each system. Further studies on pressure effect and~ the analysis of energetics of these and other similar systems are in. progress. The reactions of recoil 31S1 atoms formed by the nuclear ' transformation, 31 P(n,p)31Si, have been studied. In such systems,
'it has been shown that: recoil 31Si atoms will abstract either H
.from PH3 or-F from'PF3 to give the~ corresponding silykenes, 31 SiH2
?or 31SiF2 . The reactions of the silylenes thus formed with 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 80% triplet. -The addition of silylenes in all of 'these forms will add to conjugated dienes to
-give the corresponding silacy-clopent-3-enes. The relative i reactivities of the butadiene, various pentadienes, and hexadienes ar'e being studied and the nature of a large steric effect observed in some of the addition reactions is under serious consideration.

III-2 EFFLUENT RELEASE
SUMMARY
kntroduction Summaries of radioactive effluents released from the Nuclear:
- Science Center for.1982 are included in this-Appendix. These: data
-are presented in tabular form and include atmospheric, liquid and solid waste'rc1casco.
Particulate Releases Radioactive particulates are monitored at- the base of the
~
central--exhaust stack-and summarized on a-monthly basis. The annual avera~ge release rate was 5.57: E-11 pC1/cc. Total radio-
. activity released for- the ~ year was 3.98 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 major gaseous effluent produced and released at the Nuclear Science Center. This_ effluent is measured by:
- counting -the Argon-41 photopeak in the gaceous discharges of -the central-exhaust stack.. Total Argon-41: released during 1982 was-2.45 curies. This results.in an annual average release' rate of 3.99 E-08 -pCi/cc asL measured in the central exhaust; stack with no dilution: factors applied. . Applyint; 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. Tuese 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_72 liquid-waste releases'totalingf2.2 E 06 gallons including diluents from the Nuclear Science Center durin 1982. '
The total radioactivity released for 1982 was 2.65 x 10- Ci with an average-concentration of 3.11 x 10 6 pCi/ml. Summaries of the Eradioisotope data are presented in Tables 3 through 15 Radio-activity. concentrations for each isotope'were below the limits specifiedLin 10CFR20 Appendix:B.

I III-21 l RADIATION AND CONTAMINATION CONTROL PROGRAM Introduction l 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 h 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 measuroments 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 h 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 1982. These surveys revealed only background radiations at the site peri-meter fence. Contamination Survey The Nuclear Science Center is routinely surveyed for radio-g active contaminatian every month. This program includes the g collection, analysis and evaluation of approximately 250 smear g samples and the decontamination of areas and stored materials with removable beta-gamma radioactivities of greater than 200 [ dpm/100 cm2,
III-22 PERSONNEL EXPOSURES Radiation exposures to personnel at the Nuclear Science Center for 1982 were within the limits of 10CFR20 The maximum exposure received by an individual for the yee.r was s 1320 mrem. A total of approximately 7.91 MANREM was received for 1982. 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 14,000 samples containing approximately 21.35 curies of radioactivity were produced and processed at the Nuclear Science Center in 1982. 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 6,580 visitors to the Nuclear Science Center during 1982. The maximum exposure to any visitor as determined by film badges was less than the minimum measurable quantities. These values arr: 10 millirems for X or gamma, 40 millirems for hard beta, 20 millirems for fast neutrons and 10 millirems for thermal neutron radiations. 4
