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 L

Several. operational problems occurred during 1982 some cur.

.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 velocityLraw 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 associated with reactor systems which had tof 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 persc.nnel in supervisory and management positions resulted in having to acquire and to train new individuals for these key l positions. Efforts are, however, underway to stabilize.the staff and reduce personnel turnover.

14-a III. FACILITY OPERATIONS A.- Facility Safety and Operational Improvements Machine Shop Relocation As 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 repalnting, 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 account'ed for following evacuation of the {

facility. This was done in an effort to reduce noise and confusion d during energency evacuations. As seen in Figure 2 a solenoid 'l 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. It 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 1

-valvesnwere repacked, and-the acid pump used;for regenerating the

1on1 exchanger was remounted.on the wall.- The concrete floor-has deteriorated over the. years due to' exposure to acid, and work has now bagun on resurfacing and providing for-better drainage. 'This

, work is expected to be-completed.in 1983 E

16 B. Improvements to Reactor Systems and Experimental Facilities-New Core Loadings 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 time Core VIII (Figure 4) was established. As can be seen this change consisted simply of due installation of the transient . rod in preparation for reinitiating pulsing operations of the NSCR.

Addition 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' system, and a remote motor control switch and a power "ON" 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 incorpcrated 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 Sy7 tem Controller for Shell Laboratory As discussed in the 1981 annual report a new lab was established for the Shell 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-i menter has the capability to establish his desired timing sequence.

l 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.

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 Reclacement 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 for the reactor during the past year. On two occasions frayed 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.

L Reportable Occurrences Failure of the Linear Power Channel to Respond During Reactor l 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 p3npoint the I exact cause of failure. However, the instrument has since been i 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 satisfactorily since that time.

Reactor Operation in Excess of Licensed Power Level 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

x 24

- <were repositioned such>that the calculated actual power.and indicated. power agreed. .A second calorimetric' performed on December'lo, 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, 1982. 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 glittle

-water experienced a temperature change of approximately .5 F over L a ~ two' 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 reactorfpower increase by

. detector adjustment at any one time to no greater than 10% of l -the measured power.

Security Incidents There were two incidents-pertaining to security requirements at the NSC during 1982. However, due to public disclosure will not.be addressed in this report.

TRITIUM AND SILICON-31 PRODUCTION PROJECT Personnel-

• Dr. Yi-Noo. Tang -- Professor H L Dr. E. E. Siefert -- Post Doctorate l Recoil tritium atoms, generated from 3He(n,p)3H process with-t

. thermal neutrons from the reactor, reacted with organic compounds such as 02 H5 F, C2 H5 01 and C-C4 He to yield products either from abstraction or substitution. The-substituted products that formed

-carried a large_ amount of residual energy. The pressure. dependence )

- of the~ unimolecular decompositions of these subst'itutional products 1

'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 l

~ decomposed (or stabilized) varied as a linear function of log Pgpp.

She . effective pressure Pconsideration the relat19kp, collisional was calculated coefficient by taking of the into component 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 31 Si atoms formed by the nuclear transformation, 31P(n,p)31Si, have been studied. In such systems, it-has been shown that recoil 31Si atoms will abstractielther H from PH3 or F fr'om 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~20f 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

" 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.

In the present l and perhaps, the final phase of the project, the lignite humic acids were fractionated according to molecular size on a sephadex cclumn. The fractions obtained were analyzed for uranium content using NSC facilities and an attempt made to correlate the urnnium

{ distribution with the molecular weights of the humic acids.

Geology Personnel Dr. Thomas Tieh -- Professor Wendy Schaftenaar -- Graduate Assistant Studies were performed to determine the distribution, abundance, and nature of occurrence of uranium in igneous rocks of the Davis Mountains of West Texas. Uranium content was determined using the delayed neutron counting system at the NSC.

Radiological Safety Office DETERMINATION OF URANIUM CONTENT IN LIGNITE Personnel Dr. R. D. Neff -- Professor John O'Donnell -- Graduate Student The NSC delayed neutron counting system was used to determine uranium content of lignite samples. These results were then compared to other methods of uranium detection.

SUMMARY

h -Introduction

' 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 L

_ solid waste releases.

Particul' ate-Releases

~ Radioactive particulates are m'onitored at the base of the-

- . centra 1' exhaust stack"and summarized on a monthly basis. The '

annual average release rate was 5.57'E-11 pCi/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.

e

. 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 gaseous 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-as measured in the central exhaust stack with no dilution. factors applied. Applying.the dilution factor of

' 5.0 E-03 allowed at theisite boundary (as determined,-SAR, pages

~117-119, June 1980) results in radioactivity concentrations of

< 1% of the limits specified in 10CFR20, Appendix B, Table II, Column 1. These data are summarized on a monthly basis and presented in Table 2.

Liquid Waste Releases

Radioactive liquid effluents are collected in liquid waste holdup. tanks _ prior'to release-from the. confines of the Nuclear Science Center. -Sample' analyses for: radioisotope identification

.and radioactivity concentrations were, determined for each' release.

There were 72 liquid waste releases totaling 2.2'E 06 gallons-including diluents from the Nuclear Science Center durinE 1982.

'The total radioactivity released for 1982 was 2.65 x 10-Ci with

.anL average -concentration of- 3 11 x 10 6 pC1/ml. _ Summaries of the- '

radioisotopeEdata are presented in Tables 3 through.15 Radio .

activity concentrations for.each isotope _-were belowlthe! limits specified in.10CFR20 Appendix B.

III-21 RADIATION AND CONTAMINATION CONTROL PROGRAM Introduction The detection and elimination of radiation hazards is an integral part of the Radiation Safety Program at the Nuclear Science Center. The radiation and smear survey programs con-tribute to the control and elimination of these health hazards.

This program is effective in preventing the spread of radio-active contamination, improper storage of radioactive materials, and unwarranted exposures to radiation.

Radiation Survey The Nuclear Science Center uses an area radiation monitoring system consisting of nine (9) detector channels located throughout the Reactor and Laboratory Buildings. This system is equipped with alarm settings and remote readouts in the control and reception rooms. Radiation levels and operational checks are recorded on a daily basis. This system functions as a radiation safety monitor for the early detection of impending radiation hazards. The Nuclear Science Center Facilities and site boundaries are surveyed monthly with beta-gamma sensitive instruments. These measurements are taken to determine proper storage and identification of radio-active materials and that visitor and routine work areas are free of radiation hazards. Additionally, radiation monitoring support is provided for the reactor operations and experimenter groupc 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 r

The Nuclear Science Center is routinely surveyed for radio-active contamination every month. This program includes the collection, analysis and evaluation of approximately 250 smear samples and the decontamination of areas and stored materials with removable beta-gamma radioactivities of greater than 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 year was % 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 andEeliminate radiation exposures whenever practicable. These exposure 1 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 asfrequired 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 are 10 millirems for X or gamma, 40 millirems for hard beta, 20 millirems for fast neutrons and 10 millirems for thermal neutron radiations.
