1. INTRODUCTION This report has been prepared by the staff of the Nuclear Engineering Teaching Laboratory (NETL), The University of Texas at Austin, to satisfy the reporting requirements of the U.S. Department of Energy Contract Number At-(40-1)-3919 and 10 CFR 50.59. The report covers the period from January 1, 1985 to December 31, 1985.

The Nuclear Engineering Teaching Laboratory (NETL) is a part of the Mechanical Engineering Department in the College of Engineering at The University of Texas at Austin. The program's major equipment consists of a 250 kW TRIGA Mark-I reactor operated in pulsing and steady state modes. The Nuclear Reactor Laboratory and Neutron Activation Analysis Laboratory areas, shown in Figures 1 and 2, are located in Taylor Hall on the main university campus. A Nuclear Radiation Laboratory for other types of experiments is located in another building on the main campus. Equipment maintained by the NETL program includes a Cockcroft Walton 14 MeV neutron generator, a Lockheed Aerojet su b c ri-ti.c al assembly, a-9250 curie Co-60 irradiator and 150 kilovolt industrial X-ray source. Also available are isotopic neutron sources that include three californium-252 sources and six plutonium-beryllium sources and reference sources for instrument calibrations. A wide array of detectors and electronic equipment are available to provide measurement and analysis capability of laboratory produced or maintained radiation sources.

Changes in the NETL program occur as a continuing response to achieve effective operation of various HETL projects and program development. A major planning effort, to move the location of the laboratory activities, was i initiated during the 1984 calendar year and continued L through the 1985 calender year. The project plans to move l .the facility location from The University of Texas at Austin l main campus to the Balcones Research Center (BBC). The proposed move is in response to needs for expansion of other educational programs and facilities on the main campus and the development of the research center as a major research and engineering site. Submittal was made to the Nuclear l Regulatory Commission (NRC) in November 1984 for the

' approval of the new facility location. An NRC site visit in January 1985 and subsequent evaluation of the license application resulted in the issuance of a construction permit in June 1985. Preliminary architectural and engineering plans were approved by The University of Texas System Board of Regents in July 1985. Plans are to complete final drawings and specifications by architects and i engineers, obtain regents approval and award of funding in r-5 4

1985 the spring of 1986. Facility completion is scheduled for 16-18 months after start of construction.

Fuel elements from the dismantling of the Northrup Aircraft Division TRIGA were cbtained by donation during the 1985 year. Two shipments consisting of a total of 58 elements were added to the fuel inventory as replacement fuel and supplemental fuel for the proposed facility planned operation at 1.1 Megawatts.

Decommission and dismantling plans for the Taylor Hall facility were submitted in May 1985. Actual decommission and dismantling work is scheduled to occur after the the movement of key components from the Taylor Hall site to the-Balcones Research Center site upon completion of the proposed facility.

The Balcones Research Center facility will provide laboratories for the TRIGA reactor, neutron generator, radiation measurement, preparation and processing of radioactive samples, and office space. Although the facility move consists primarily of moving the present TRIGA facility and other program activities into a single building at the Research Center, several improvements to the reactor facility are planned to extend facility capability. These include above ground shield structure for access to horizontal beam tubes, and increased power and pulse parameters. Plans are to utilize the present fuel and move some other components from the old to the new facility.

Many of the components such as reactor structure, and instrumentation and control system are to be replaced. A few components such as control rod drives will be reconditioned.

1985 D. Report to the College of Engineering Each year the Reactor Committee provides a report to the Dean of the College of Engineering describing activities of the committee and a review or assessment of the operation of specific portions of the NETL program concerning the reactor and other radiation producing equipment. Harris Marcus, Reactor Committee Chairman, summarized the activities during this period saying, "A great deal of enthusiasm exists within the Nuclear Engineering Teaching Laboratory in spite of the extensive paperwork load associated with the proposed move to B.R.C. The program has again completed a busy, successful year."

Specific items of interest included:

1) The main effort in the program was associated with the development of a new reactor facility at Balcones Research Center. A plan has been developed and preliminary work with NRC personnel has progressed in an orderly manner.

The next few months should lead to approval to proceed to build the new reactor facility at B.R.C.

2) Northrup donated 59 partially used fuel elements for use in the TRIGA facility. The transfer of the fuel over two separate delivery dates was well organized and proceeded with no incidents.

3) The reactor remained operating efficiently while the rest of Taylor Hall was being torn down around it.

1985 III. LABORATORY DEVELOPMENT A. Organization

-Dr. Dale E. Klein continued as the Director and Dr.

Thomas L. Bauer continued as Reactor Supervisor / Assistant Director during the past year. An administrative change in the Office of the President replaced Peter T. Flawn with William H. Cunningham as President of The University of Texas at-Austin and assigned Gerhard J. Fonken as Executite Vice President and Provost.

Appointments of part time staff during the year included two temporary.short term student appointments and a longer term appointment. All facility staff positions became complete-with the appointment of R. Clements as a Laboratory Research Assistant. Mr. Clements has previous licensed operator experience and should provide an asset to the future program goals of the facility. Other staff personnel remained unchanged.

. One change in the Nuclear Reactor Committee replaced the student member on committee. Other key faculty and university support personnel remained unchanged.

.B. Nuclear Engineering Teaching Laboratory The Nuclear Engineering Teaching Laboratory is part of the Nuclear Engineering Program at The University of Texas.

The Nuclecr Engineering Teaching Laboratory's central feature is a Mark I TRIGA thermal fission reactor.

Originally licensed by the Atomic Energy Commission to operate at 10 KW in 1963, the nuclear reactor and the associated laboratory equipment have been updated over the past years and the research capabilities of the Laboratory are now more diverse. In 1968, the facility license was amended to allow the TRIGA reactor to operate at a steady state power level of 250 kW which increased experimental capabilities.

Other radiation producing devices maintained by the Laboratory are a thousand curie Co-60 irradiator, vertical neutron beam tube, suboritical assembly, industrial x-ray source, 14 MeV neutron generator, and several isotopic neutron sources. Different types of radiation detection devices provide the capacity to monitor or analyze the various radiation sources.

One of the functions of the nuclear reactor and its associated equipment has been to teach and demonstrate the fundamentals of reactor operation. Another function has been the demonstration of specific applications of nuclear technology. Several organized classes routinely utilize the 14

1985 reactor facility. Courses utilizing the reactor and associated facilities are listed in Table 3 Classes, organizations and groups are provided tours or demonstrations of the' reactor and its associated experimental facilities. Approximately 850 persons were admitted into the reactor facility during the past year.

The use, operation, regulation and inspection of the Nuclear Engineering Teaching Laboratory is controlled by the United States Nuclear Regulatory Commission, the Nuclear Reactor Committee of The University of Texas, the Director of the Nuclear Engineering Teaching Laboratory, the Radiation Safety Committee and the Texas Department of Health Division of Radiation Control.

C. Neutron Activation Analysis Laboratory The Neutron Activation Analysis Laboratory has provided nuclear analytical support for individual projects ranging from student project support for classes to measurements for faculty research projects. Student project support is in the areas of engineering, chemistry, physics, geology, biology, zoology, and other areas. Research project support includes elemental measurements for environmental and investigative research projects. Scientific articles based upon the results of sponsored and non sponsored research by this laboratory have been published or accepted for publication in several journals and proceedings, and have been presented at conferences at the state, national and international level.

Radiation measurement systems available include gamma ray spectroscopy with HpGe detector and microcomputer controlled acquisition and analysis system, Si(Li) detector and multichannel analyzer for X-ray measurements, alpha-beta proportional counter, scintillation detectors, neutron detectors and associated electronic modules to accomplish several types of standard nuclear measurements. An important function of the laboratory is to support various research applications with the neutron activation analysis method or other techniques related to nuclear radiation measurements.

D. Nuclear Radiation Laboratory The Nuclear Radiation Laboratory is utilized by staff and students of the Nuclear Engineering Program at The University of Texas at Austin. The laboratory is located in an area of the Engineering Science Building. A 14 MeV Texas Nuclear neutron generator is the main feature of the laboratory. Three californium-252 neutron sources are also available for use. The facility, with installed shielding, provides an area where students and staff can perform experiments utilizing not only the high energy neutrons from 15

1985 the neutro'n generator but fission spectrum neut Sns from Cf252. In addition to the neutron generator and the californium sources, other smaller radioactive sources are also used within the confines of the Nuclear Radiation Laboratory.

! 1985 IV. Facility Operations Summary A. Operating Experience During the period no significant deviations from normal operating conditions were observed. Pulse reactor operation remains suspended until proper operation of the removed uncompensated ion chamber is confirmed or an appropriate substitute is installed. Established operating procedures and other required procedures remained unchanged.

Licensed activities were performed by two persons with Senior Operator Permits, T.L. Bauer and M.G. Krause.

Operating activities were in support of reactor operations, nuclear engineering, sample irradiations, research and education or demonstrations. No new experiments were proposed or approved. Excluding operation for demonstration, instruction or routine surveillance, the major experiment performed was neutron activation to support various research activities. Maintenance during the period consisted primarily of routine equipment repair and adjustments.

B. Reactor Shutdowns Reactor shutdowns (scrams) occurring during the reporting period are summarized in Table 4, categorized according to the type of initiating event. Safety system scrams are protective actions to shutdown the reactor that are caused by the proper operation of the safety system but are not the result of an operator error or an intentional action of the operator. Operator error scrame are the result of judgement errors or procedural errors. Instrument and power failure scrams are protective actions that result from loss safety system function. Intentional scrams are operated initiated scrams such as tests. Manual action scrams are classified either safety or intentional as determined by the cause of the manual scram action.

Inadvertent scrams are all unintentional shutdowns of the reactor by the protective action of the safety system.

Table 5 compares the number of inadvertent shutdowns during this reporting period to previcus reporting periods.

1985 C. Utilization Reactor utilization data for this reporting period is summarized in Table 6. A summary of reactor utilization since initial criticality is shown in Table 7. Bar graphs comparing annual burnup and quantities of samples irradiated since initial criticality are shown in Figures 4 and 5.

D. Maintenance During this reporting period maintenance consisted primarily of routine repair and adjustment.

E. Facility Changes Operation of the reactor in the pulse mode has been dtscontinued until the operation characteristics of the compensated chamber as related to pulsing is established.

This evaluation is a low priority since current activities of the facility do not require pulsing and future facility operation will be reevaluated in relation to the new facility proposal.

The acquisition of fuel included the installation of additional fuel storage racks in the reactor pool. Four two section racks with a total of twelve elements each were in installed. Eight single section racks provide the necessary storage for the remaining fuel elements, temporary storacc for fuel removed from the reactor core and storage for other core components.

1985 F. Radiation Exposures A summary of radiation exposures during this reporting l period to facility personnel, students, and visitors is shown in Table 8. The average exposure per individual and the greatest exposure per individual for each group is summarized in Table 9. No exposures in excess of the limits of 10CFR20 opourred during this period.

'G . Area Radiation Surveys An sr.nual~ summary of the normal radiation levels measursd in the laboratory is shown in Table 10. The results of routine surface and pocl water contamination surveys are summarized in Table 11. Environmental surveys performed outside the laboratory are summarized in Table 12.

H. Badioactive Effluents

1. Gaseous Wastes Gaseous discharge during the reporting period is

. limited to leakage of Ar41 from the reactor laboratory.

The total estinated amount of radioactivity released was calculated based on experimental data.

Measurements indicate the equilibrium concentration of Ar41 is 4 x 10^-8 Ci/m3 Estimate of the release is calculated from the monthly number of full power hours operated during the period. Although air leakage from the laboratory is restricted, an effective air change rate of two per hour (.36 m3/sec) is assumed with dilution at the release point (.14 sec/m3). A summary of the calculated radioactive gaseous discharges during the reporting period is presented in Table 13

2. Liquid Waste No liquid radioactive waste was discharged during the reporting period. Efforts are made to avoid liquid waste disposal by appropriate evaporation or absorption techniques for small volumes and purification by resin treatment for large volumes.

3 Solid Waste The activity and amounts of solid waste discharged during the reportin6 period are summarized in Table 14.

All solid waste materials were packaged and shipped, along with radioactive waste generated in other departments, by the Safety Office. Waste shipments are performed by Isotex, Friendswood, Texas.

Heat Transfer and Friction Factor Analysis for Artificially Roughened Surfaces

. Sponsor: Center for Energy Studies National Science Foundation University Research Institute Personnel: Dale Klein, NETL J. Parker Lamb, Mech. Eng.

Mike Krause, NETL

Description:

The proposed research is to determine the heat transfer and friction characteristics for surfaces with discrete roughness geometry. Two major aspects are to be examin6d in that this is both an experimental and av. analytical investigation. Values of R(h+) and G(h+) in the universal velocity and temperature profiles will be examined. New experimental techniques have been developed at The University of Texas at Austin to measure local heat transfer values surrounding discrete roughness elements. A test assembly to examine artificially roughened surfaces is being designed. In addition, a new aralytical method has also been developed to determine R(h+) and G(h+) values without making detailed velocity and temperature profile measurements. Analytical predictions will be made utilizing fundamental parameters in boundary layer theory coupled with the latest information on rough surfaces using integral techniques. Results from the experimental and analytical methods will be compared in order to gain insight as to the dominant mechanism involved for the use of discrete rough surfaces. This research has fundamental application for heat transfer augmentation.

Fission Product Absorption in Continuously Processed Fission Suppressed Fusion Hybrid Reactor Blankets Sponsor: Department of Energy Fellowship Center for Fusion Engineering Personnel: Dale Klein, NETL J.W. Davidson, NETL Ann Patterson-Hine, NETL

Description:

, The effect on blanket performance of fission product absorption in lithium / molten salt hybrid reactor blankets is being-investigated. Neutron flux spectra in blankets of varying fuel and fission product compositions are being t

determined using the discrete ordinates codes, ANISN, and DOT-IV with multigroup cross section data from VITAMIN-C.

34

1985 ,

Flux levels and spectrally weighted cross section libraries for the blanket materials, fuel, and fission products will be= established for use in the depletion analyses.

Generation end depletion of the various isotopes in the blanket will be calculated using ORIGEN. A lumped fission product model will be used in the transport calculations; however, detailed information concerning the constituents of the lump will be included in the depletion analysis.

In addition to full and partial reprocessing of the -

molten salt, alternative processing concepts will be investigated. A parametric study of the effects of

]

processing performance will be carried out. This study will result in the characterization of the fission product concentration'in the molten salt with respect to isotopics, neutron absorption, and the effects on blanket parameters j such as the tritium and fissile breeding ratios.

35 N .

1985 -

Carbon dioxide miscible displacement is one method of enhanced oil recovery which can increase ultimate prodtetion beyond that obtained from primary and secondary methods, t

Current sources of CO2 for this application are obtained from natural CO2 wells, by-product CO2 and on-site generation of CO2. This project is to examine the feasibility of obtaining CO2 and other valuable by-products from Texas lignite using a high temperature gas-cooled nuclear reactor for process heat. An integrated concept will be developed to include the nuclear process heat and the valuable by-products converted from the Texas lignite.

Thermal Analysis of Nuclear Shipping Containers Sponsor: Sandia National Laboratories Personnel: Randy "anteufel Dale E. Klein

Description:

The thermal analysis of shipping containers to be used in the transport of spent nuclear fuel is an important safety issue. Sandia National Laboratories has been involved in safety issues for the transport of nuclear material for many years. The University of Texas at Austin (NETL) has been involved in the specific issues of thermal analysis of these containers for several years. The current project is intended to benchmark a thermal analysis computer code (Q/TRAN) and pre and post processing software PATRAN-G using four standard model problems. Comparisons will be made with other applicable codes currently available at UT (including HEATING 5). Sensitivity studies will be performed to further evaluate Q/TRAN's suitability for thermal analysis. Enhancements, if any, that will increase the current capabilities of the software will be suggested and developed if feasible.

Application of COBRA for shipping Cask Analysis Sponsor: Sandia National Laboratories Personnel: Tom Dolbear, Mechanical Engineering Dale Klein, NETL

Description:

A thermal hydraulic computer code, COBRA, has been applied for both steady state and transient analysis. Previous research at The University of Texas at Austin involved the modification of the COBRA code and created a new version COBRA *GCFR 4P/UT. The current research is directed towards 36

1905 l i

modifying COBRA *GCFR 4P/UT so that it may be applied to transient conditions for shipping cask analysis. One speciific modification will be to develop a more l sophisticated model for analyzing radiation heat transport.

Results using this code will be compared with the results from Q-TRAN and HEATING-6 where possible. In addition, recommendations will be made regarding CuBRA's use for dry storage analyses.

Transportation Analysis of Spent Fuel & High Level Wastes Sponsor: Nuclear Engineering Teaching Laboratory Personnel: Danny Smith, NETL Dale Klein, NETL Thomas L. Bauer, NETL

Description:

The current methodology (i.e., overall plan for analysis which integrates discrete computer codes and other computational elements) for analysis of high-level waste and spent fuel transportation is not directed toward minimizing radiation exposure but rather is an attempt to demonstrate minimum compliance with statutory and regulatory requirements. The current models (i.e., algorithms and computer codes) exhibit deficiencies and the thesis to be examined for this work is that more representative and credible models can be developed for radioactive waste transportation analyses and thos2 models can be integrated into a methodology that allows eclection of routes resulting in minimum radiation exposure. This work will also examine options for cost-effective enhancement of transportation operations with the intent of minimizing public and occupational exposure to radiation as well as exposure to radiation and non-radiation transportation risks (recognizing that elimination of risk is neither possible nor necessary but that achievement of exposures as low as reasonably achievable, ALARA, is prudent).

Neutron Transport Studies: Neutron !!ultiplication by Beryllium Sponsor: National Science Foundation Personnel: Nolan E. Hertel, Center for Fusion Engineering

Description:

l

37

r 1905 The use of beryllium as a neutron multiplier is central to the current fusion breeder design. Recent measurements of beryllium neutron multiplication and reevalutions of beryllium nuclear data indicate that the multiplying performance of beryllium previously has been overestimated, possibly by as much as 255 If beryllium's performance as a-neutron multiplier has indeed been overestimated even by as much as 10%, the direction of the fusion breeder program in the United States might well change. It is tantamount to the current fusion breeder concepts that the issue of beryllium neutron multiplication be resolved. Therefore, an experiment using a spherical shell of beryllium is being proposed.

The beryllium experiment has been designed to measure multiplication resulting from DT, DI. PuBe, and 252Cf neutron sources being placed in a spuerical shell. By doing so the sensitivity of the multiplication to spectral shape can be observed. In addition, the use of these rour sources helps to simulate the effect of neutron source deCradation in a fusion reactor. The neutron multiplication will be obtained directly from summing weighted Bonner ball measurements of the neutron leakage. The neutron multiplication obtained in this manner will provide a number which tests the capability of the current beryllium nuclear data to calculate total neutron multiplication.

Neutron Therapy Beam Heasurements Sponsor: National Institute of Health

- Public Health Service Personnel: Nolan Hertel, Hechanical Engineering Robert Graves, Universtiy of Rochester

Description:

The energy spectra of the new neutron beam at H.D. Anderson Hospital will be measured. This will be done by using two techniques: (1) the foil activation technique in which neutron energy spectra are obtained by unfolding threshold foil activation data, and (2) the pulse height unfolding method in which both neutron and photon energy spectra are obtained by one-dimensional pulse height unfolding using experimentally measured response functions for mono-energetic photons and neutrons. Spectra will be measured in air and in tissue-equivalent liquid phantom as a function of field size, depth along central axis, off-axis distance, and beam modifying devices. Data measured under these conditions will be used to compute kerma ratios and ionization chamber sensitivity factors needed to calibrate t the therapy beams. The results will also provide information on both the dosimetric and biological 38 I - .__ .___

Heasurement of Nutrional and Other Elements in Bread Sponsor: Nuclear Engineering Teaching Laboratory Food.Research Center, University of Idaho Personnel: F.Y. Iskander K.R. Davis

Description:

Sgyptian bread samples were collected from several locations across the country. Cereal and other components used for bread making depend on location _(city, village or nomad).

-The objective of the study is to determine the concentration of nutritional elements in the different bread samples and to study a possible correlation between the iron content of bread and cases of iron deficient anemia.

Determination of Rare Earth and other Elements in Bottom Sediments from the Mediterranean Sea Sponsor: Nuclear Engineering Teaching Laboratory Oceanography Dept., Alexandria University Personnel: F.Y..Iskander N. Dowider

Description:

Silt is deposited directly in front of the Rosetta and Damietta mouth of the Nile where distribution of sediments is not governed by the bottom configuration. Fine sediments

-are distributed in deep depositional environments as well as in shallow water areas. The distribution of the sediments thus seems to be mainly affected by acting currents in the area. Sediments passing through the Rosetta and Damietta branches are distributed asymmetrically on either side of the mouths of the two branches. In this study the concentration of 30 elements were determined in twenty different samples.
