Tellurium interference in /sup 129/I activation analysis

Description: Measurement of /sup 129/I at low levels is required for effluent control, environmental assessment and tracer studies in the natural environment. Low level /sup 129/I analysis has also been used for measurement of natural-fission-produced /sup 129/I in minerals and ores as well as meteorites. The most sensitive method for /sup 129/I measurements is neutron activation analysis of iodine separated from a suitable sample. Minimum sample processing prior to neutron activation is desirable in order … more

Phase 1 of the Hanford Environmental Dose Reconstruction Project

Description: This report summarizes the water pathway portion of the first phase of the Hanford Environmental Dose Reconstruction (HEDR) Project, conducted by Battelle staff at the Pacific Northwest Laboratory under the direction of an independent Technical Steering Panel. The HEDR Project is estimating radiation doses that could have been received by the public from the Department of Energy's Hanford Site, in southeastern Washington State. Phase 1 of the water-pathway dose reconstruction sought to det… more

Phase 1 of the Hanford Environmental Dose Reconstruction Project

Description: For more than 40 years, the US government made plutonium for nuclear weapons at the Hanford Site in southeastern Washington State. Radioactive materials were released to both the air and water from Hanford. People could have been exposed to these materials, called radionuclides. The Hanford Environmental Dose Reconstruction (HEDR) Project is a multi-year scientific study to estimate the radiation doses the public may have received as a results of these releases. The study began in 1988. During … more

Operation and routine maintenance of the automatic monitor for hexavalent chromium in Columbia River water

Description: A Technicon Autoanalyzer for hexavalent chromium has been installed at the Automatic Columbia River Monitoring Station located along the west bank of the Columbia River. The sample water is delivered to the building by a deep well jet pump for continuous monitoring for gross gamma, {sup 131}I, hexavalent chromium, and for emergency water samples. An alarm system indicates unusually high activity levels. The unit was installed to detect hexavalent chromium which reaches the river as a result of … more

Tritium extraction facility study - 1965

Description: This study was prepared in support of AEC-requested reactor case studies. Two of the cases include local separation and purification of tritium from Hanford irradiated aluminum-lithium alloyed slugs after 1974, at which time, the Savannah River Plant would be shut down. Consideration is given to processing N Reactor rods or {open_quotes}K{close_quotes} Reactor I&E slugs. Quantities of tritium to be produced would be five kilograms per year in one case and seven kilograms per year in the other c… more

Transient calculation techniques

Description: This paper presents a calculation of transient events in the Hanford piles due to the build up of fission product nuclides with a very large neutron absorption cross-section. In particular it was found after operation of the first major pile that Xe{sup 135} was a short lived isotope which built up in the pile, and which possessed a very large cross-section. The dynamics in number density of this isotope has a major impact on the reactivity behavior of the piles, and in particular on the start-… more

Low Latency Remote Memory Access on the Intel Paragon

Description: We describe a cooperative project between Pacific Northwest Laboratory and Intel on providing low latency communications on the Intel Paragon. Our interest is in developing modules that are tailored to specific types of communication and are optimized for these cases. The modules described are implemented as simple extensions to the Paragon operating system. The first extension supports remote reads, writes, and accumulates on subsections of matrices. This module is intended to be used where th… more

Environmental status of the Hanford Reservation for December 1966. (Annual summary)

Description: Data are summarized on levels of radioactivity in environmental samples collected at Hanford during 1966, including detailed data on samples collected during December. Data are included on the radioactivity in fallout from Chinese and Russian nuclear weapons test, samples of drinking water and Columbia River water, the /sup 56/Mn content of Columbia River water sampled at various locations, the /sup 131/I content of gaseous wastes and surface waters, and the radioactivity of soil samples from t… more

First FFTF local clad temperature tests with 7-pin bundles

Description: A series of three tests will be performed to evaluate: temperature gradients between wall and central coolant channels in an FFTF fuel assembly to assess thermal stress level in the pins. The potential hot spot caused by the presence of a wire wrap spacer. A single electrically-heated 7-pin fuel assembly model will be used to perform these tests. The configuration is summarized in Table 1 and the instrumentation in Figure 1. Pins 1, 2, and 7, along with the local coolant thermocouples, characte… more
