Temperature Measurement in Operating Reactors: In-Reactor Temperature Measurement Associated With Fuel Element Testing

Description: The Fuel Development operation at Hanford uses a variety of in-reactor facilities to test experimental and prototypical fuel elements. High pressure-high temperature water loops in constant use are the 6 in. {times} 9 in. ETR core facility, the 3 in. {times} 3 in. ETR reflector facility and four front-to-rear loops in the 100-K East reactor at Hanford. Low pressure water cooled test facilities in use are located in the MTR the various Hanford reactors. Stainless steel sheathed the thermocouples… more

The alleged 231-Z discharge of plutonium to the 216-Z-19 Ditch, February 1977

Description: This report describes circumstances involved in the alleged 91.2 grams of plutonium released to the 216-Z-19 Ditch from the 231-Z facility. The following areas were reviewed: 231-Z liquid waste data collected by Battelle-Northwest and Rockwell Hanford Operations (Rockwell); the sampling methods used by Battelle and Rockwell; and operating conditions in the 231-Z and 234-5Z Buildings at the time of the alleged release.

To Organize and Evaluate an Intramural Sports Program for Boys at Schreiner Institute

Description: The purpose of this study was to evaluate the intramural sports program at Schreiner Institute, Kerrville, Texas, for the school year, 1947-48, to determine its adequacy in meeting the aims and objectives of a reorganized program of intramural sports set up in the school at the beginning of the year, 1947-48. Attention was directed to the special need for the program, to its aims and objectives, to its plan of procedure, and to the outcomes at the end of the year.

Proposal for charging test fuel element with corrugated outer jacket, GEH-10-62

Description: Localized tensile necking and splitting of the Zircaloy-2 clad on coextruded uranium cored fuel elements may represent an ultimate exposure limit. One way to increase the total energy capability of the fuel element is to corrugate the outside cladding so its perimeter is greater than that of a circle circumscribing the equivalent cross-sectional area. Thus swelling of the core will be accommodated by bending of the cladding rather than by large cladding tensile strains. The principal purpose of… more

Preliminary report on CX-2 N-inner fuel tube number 1055-8

Description: The real cost of metallurgical examination of irradiated fuel elements is several times that of fuels before irradiation. Since post-irradiation study is necessary to determine the performance of prototype fuel designs in a reactor environment, complete physical characterization before irradiation provides an economical and efficient basis for comparing experimental data. Without such comparative study, unexpected damage to fuels in the reactor would be difficult, if not impossible, to interpre… more

DHS Workshop -- Homeland Security: New Challenges for Decision Making Under Uncertainty

Description: A workshop addressing the decision-making challenges confronted by the United States Department of Homeland Security (DHS) in the face of large uncertainties, complex value systems, and multiple stakeholders was held November 13-14, 2003, in Washington, D.C. Forty-six participants drawn from the DHS, other government agencies, universities, national laboratories, and the private sector attended the workshop. The goals were: (1) to develop a common understanding of the range of decisions DHS pro… more

Application of Neural Networks to Flight Test Diagnostics

Description: A system has been designed which can provide summary information about specific noisy electric pulses that are generated during flight testing. This is important from a telemetry viewpoint, since limited bandwidth often rules out transmitting all of the pulse data. The system is based on a neural network processing paradigm. The neural network serves as a mapping between pulse data inputs and pulse category outputs. Output categories correspond to presence or type of component failure. Extensiv… more

Nuisance Source Population Modeling for Radiation Detection System Analysis

Description: A major challenge facing the prospective deployment of radiation detection systems for homeland security applications is the discrimination of radiological or nuclear 'threat sources' from radioactive, but benign, 'nuisance sources'. Common examples of such nuisance sources include naturally occurring radioactive material (NORM), medical patients who have received radioactive drugs for either diagnostics or treatment, and industrial sources. A sensitive detector that cannot distinguish between … more

Neutron Irradiation of Sapphire (Al 2 O 3 )

Description: A centerless-ground, 0.25-in.-diam. by 0.75-in.-long sapphire single crystal exposed to an integrated thermal neutron flux of 2 x 10 19 nvt at a temperature of 350 deg C (660 deg F) did not change its dimensions appreciably simple beam, with slightly less force than was required to break a similar unirradiated rod. In a darkened room the irradiated sapphire begins to thermoluminesce noticeably at 280 deg C (535 deg F) and most of the amber or brown coloration produced by the pile exposure is re… more

An Improved Continuous-Indicating Dew-Point Meter

Description: Note presenting the development of a continuous-indicating dew-point meter that automatically maintains a mirror surface at the dew point. The instrument was found to have an average accuracy of 1 degrees Fahrenheit over the range of 75 to -45 degrees. The accuracy of the instrument is uncertain at temperatures below 32 degrees Fahrenheit by the difference in vapor-solid and vapor-liquid equilibrium temperatures.

Technical Investigation of Autoclave Failure

Description: On July 31, 1959, an autoclave ruptured while being used for thermal cycling studies of Plutonium Recycle Test Reactor (PRTR) plutonium-aluminum fuel elements. Since stand-in materials were being used in this test, no contamination was involved. This accident could lead to inference of greater hazards associated with PRTR fuel designs than had previously been postulated. An ad hoc technical investigation committee was appointed by the Manager Reactor and Fuels Research and Development, to stud… more

Evaluation of passive alpha detectors for sensitive/inexpensive/fast characterization of radiological contamination on surfaces and in soils

Description: Passive alpha-particle detectors, originally developed for indoor radon measurements, offer the potential for cost-effective and sensitive measurements of radiological contamination in soils and on surfaces for field screening and radiological survey applications. We have carried out field demonstrations of electret ionization chambers (EIC`s) and alpha track detectors (ATD`s). The EIC`s offer the advantages of immediate on-site readout, good sensitivity, ruggedness, and simplicity of operation… more

Use of passive alpha detectors to screen for uranium contamination in a field at Fernald, Ohio

Description: This paper reports the results from a field test of newly developed techniques for inexpensive, in situ screening of soil for alpha contamination. Passive alpha detectors that are commercially available for the detection indoor airborne alpha activity (i.e., {sup 222}Rn) have been modified so they can be applied to the detection of alpha contamination on surfaces or in soils. Results reported here are from an intercomparison involving several different techniques with all measurements being mad… more

Electrical performance of a three-stage flux compression generator system

Description: In previous papers at prior Megagauss Conferences, we have described the design and performance of two stage FCG pulsed power packages. This paper extends the effort to a three stage pulsed power package that increases the power amplification and versatility of the self contained packages. The first tow stages are helical FCGs. The second stage is energized by using a magnetic coil connected to the first FCG. The coupling technique is similar in concept to the cascaded devices previously demons… more

Projectile charge state dependence of M-shell ionization of Au, Pb, Bi, and U by 1. 42-MeV/amu fluorine ions

Description: The present study was undertaken to determine the direct ionization and electron capture contributions to vacancy production in the M-shells of /sub 79/Au, /sub 82/Pb, /sub 83/Bi and /sub 92/U for incident /sup 19//sub 9/F ions. M-shell x-ray production cross sections have been measured for 1.42-MeV/amu /sup 19//sub 9/Fq/sup +/ ions for q = 4,5,6,8,9. Enhancements in the target x-ray production cross sections were observed for projectiles with one and two K-shell vacancies over those without K-… more
