Assessment of fire hazards in buildings housing fusion energy experiments

A number of materials in and within the proximity of buildings housing fusion energy experiments (FEE) were analyzed for their potential fire hazard. The materials used in this study were mostly: electrical and thermal insulations. The fire hazard of these materials was assessed in terms of their ease of ignition, heat release rate, generation of smoke, and the effect of thermal environment on the combustion behavior. Several fire protection measures for buildings housing the (FEE) projects are analyzed and as a result of this study are found to be adequate for the near term.

Determination of continuous gamma-ray spectra over the energy range 0. 1 to 8 MeV. [RETECTUR code] (open access)

Determination of continuous gamma-ray spectra over the energy range 0. 1 to 8 MeV. [RETECTUR code]

An experimental facility was established at LLL to characterize radiation fields produced by a variety of sources and transmitted through various shielding materials. Specific techniques for acquiring and reducing continuous gamma-ray energy spectra are discussed including NaI(Tl) detectors. Use of several detector sizes allowed study of a wide variety of source intensities and calculation of response matrices for a number of collimated detector configurations. A computer program to perform the data reduction by an iterative unfolding process is described. The reduction technique discloses the continuous gamma-ray energy spectrum over the range 0.1 to 8 MeV as opposed to the traditional peak intensity analysis. 11 references.

Executive-style briefings on selected repository design issues (open access)

Executive-style briefings on selected repository design issues

This document is a collection of executive-style briefings on selected repository design issues. Most of the briefings discuss differences between the US repository design bases presented in US Working Draft on Repository Physical Descriptions in a Salt Formation, prepared in support of INFCE discussions of May 1978 and the FRG-Netherlands design bases, presented in Design Study of a Radioactive Waste Repository to be Mined in a Medium-Size Salt Dome by Hamstra and Velzeboer, Netherlands Energy Research Foundation, January 1978. Advantages and disadvantages of the two sets of design bases are discussed, and the impacts of adopting either of these bases on the other's programs and positions are identified.

Fluid loads on LOFT DTT shrouds located in reactor vessel downcomer and DTT thermal loads during nuclear LOCE (open access)

Fluid loads on LOFT DTT shrouds located in reactor vessel downcomer and DTT thermal loads during nuclear LOCE

A thermal analysis was performed on a LOFT drag disc turbine (DTT) for a nuclear LOCE. Thermal gradients through the DTT shroud and turbine body, and temperature differences between body and shroud were calculated. This was done to determine the possible need for additional stress analyses of the DTT shroud to body welds based on thermal loads for a nuclear LOCE.

Fracture mechanics evaluation of some LOFT blowdown system and primary coolant coldleg welds (open access)

Fracture mechanics evaluation of some LOFT blowdown system and primary coolant coldleg welds

Fracture mechanics evaluations were performed for three welds in the LOFT blowdown system and one weld in the LOFT primary coolant system. Because the applied stress is not known, a sensitivity analysis was run. The assumed initial defect size was one that had a small probability of being missed; applied stresses of 68.9, 137.8, 206.7, and 344.8 MPa were used. It was found that at the lowest stress (68.9 MPa or 10 ksi) the number of cycles from the initial size to rupture was over 6 x 10/sup 6/. The current calculations indicate that with the worst crack configuration--depth-to-length ratio (a/2c) of 0.10--about 1000 cycles with a peak stress of 227.5 MPa (33 ksi) will be needed to propagate the 0.5 x 5.1 cm (0.2 x 2.0 in.) crack to failure.

INREM II: a computer implementation of recent models for estimating the dose equivalent to organs of man from an inhaled or ingested radionuclide (open access)

INREM II: a computer implementation of recent models for estimating the dose equivalent to organs of man from an inhaled or ingested radionuclide

This report describes a computer code, INREM II, which calculates the internal radiation dose equivalent to organs of man which results from the intake of a radionuclide by inhalation or ingestion. Deposition and removal of radioactivity from the respiratory tract is represented by the ICRP Task Group Lung Model. A four-segment catenary model of the GI tract is used to estimate movement of radioactive material that is ingested or swallowed after being cleared from the respiratory tract. Retention of radioactivity in other organs is specified by linear combinations of decaying exponential functions. The formation and decay of radioactive daughters is treated explicitly, with each radionuclide species in the chain having its own uptake and retention parameters, as supplied by the user. The dose equivalent to a target organ is computed as the sum of contributions from each source organ in which radioactivity is assumed to be situated. This calculation utilizes a matrix of S-factors (rem/..mu..Ci-day) supplied by the user for the particular choice of source and target organs. Output permits the evaluation of crossfire components of dose when penetrating radiations are present. INREM II is coded in FORTRAN IV and has been compiled and executed on an IBM-360 computer.

Lawrence Livermore Laboratory Geothermal Energy Program. A Status Report on the Development of the Total-Flow Concept (open access)

Lawrence Livermore Laboratory Geothermal Energy Program. A Status Report on the Development of the Total-Flow Concept

The technology development activities of the Geothermal Energy Program at the Lawrence Livermore Laboratory are summarized. Significant progress toward development of the Total-Flow concept was made during FY 1978. The results show that the original goal of 70% engine efficiency for the Total-Flow impulse turbine is achievable, that a Total-Flow system is competitive economically with conventional systems, and that the Total-Flow concept offers the benefit of more efficient utilization of geothermal resources for electric power production. The evaluation of several liquid expanders designed for low-temperature (including geopressured) resources suggests that if development were continued, these expanders could be used in combination with conventional systems to increase overall system efficiency. Although the program was terminated before complete field testing of prototype systems could be carried out, the concepts have been adopted in other countries (Japan and Mexico), where development is continuing.

Mortality, migration, income, and air pollution: a comparative study (open access)

Mortality, migration, income, and air pollution: a comparative study

The interrelationships among different demographic factors, specific causes of death, median family income, and estimated air pollution emissions were examined. Using the Medical Data Base (MEDABA) developed at Brookhaven National Laboratory, the entire population of the United States was cross-tabulated by income and emission levels of air pollutants. Path analysis was used to examine a number of patterns and relationships for each age, race, and sex group containing a minimum of 10,000 persons. Competitive and complementary effects were observed. These effects were frequently age dependent and occasionaly sex related. This specialized data base, the application of path analysis, and the development of a dynamic population and mortality model, in combination, proved to be a useful tool for investigating the effects of energy related pollutants on the exposed population.

Quark--parton model with large parton k/sub T/ (open access)

Quark--parton model with large parton k/sub T/

The quark--parton model is generalized to allow for arbitrarily large parton k/sub T/. Since it is expected that < k/sub T/ > will rise with Q/sup 2/ in (highly virtual) photon mediated processes, this generalization is necessary to restore the applicability of the quark-parton model. By treating k/sub T/ as an essential kinematical variable, the introduction of a new scaling variable z is considered. Together with Bjorken's x variable, a unified kinematical description is given of the four distribution functions: hadron structure functions and jet decay functions for spacelike and timelike photons. The possibility of a simple interpolating universal function is considered. Phenomenological determination of that function is examined in detail. Predictions on R, parton < k/sub T/ >, hadron < p/sub T/> in jets, etc., are made with the dimuon < q/sub T/ > being used as an input. The usual relation <q/sub T/ > = ..sqrt..2 < k/sub T > is shown to be false in the region where k/sub T/ is not small compared to k/sub L/, a situation which prevails in the production of dileptons recently measured. The k/sub T/ distributions for timelike and spacelike cases are shown to be not identical. The model is consistent …

Removal of plutonium from high-level caustic waste solutions using bone char: pilot study

Pilot studies have been completed using 275-..mu..m bone char as an adsorbent for the removal of plutonium, in concentrations ranging up to 8 mg/liter, from caustic waste solutions. These waste solutions were adjusted to an approximate pH of 8 before they were passed through columns of the bone char. Overall decontamination factors of about 5 x 10/sup 9/ were obtained. A tentative design of a caustic waste treatment system utilizing cartridge filters and bone char columns was made. Its advantages and possible cost saving benefits are assessed.

Revegetation Following Artificial Disturbance. Three Year Progress Report, June 1, 1975--February 28, 1978

The purpose of the study was to look at some of the potential problems associated with reseeding or reclamation in the buffer zone at the Rocky Flats nuclear weapons plant near Golden, Colorado. During the time covered by this report, another contract dealing with the Grasslands Irradiation Site was transferred to this contract. It was proposed that plant sensitivity to an internal alpha dose, such as might be encountered on Pu contaminated or uranium mine mill tailing contaminated soils, be measured using chromosome aberrations as the end point. This three year report is divided into two subproject reports; one dealing with the Rocky Flats work and one dealing with the grasslands irradiation study. The objectives of the first study were to determine a rapid and feasible method of revegetation;determine a revegetation method such that the vegetation will revert to a natural system as rapidly as possible; and develop a predictive model for soil movement by wind during the revegetation period. The results of the second investigation to date are as follows. There was no change in diversity over the last 3 year period. There was no change in coefficient of community over the last 3 year period. There was no …
