[D. W. Griffith]

[D. W. Griffith]

D. W. Griffith is shown standing on the roof of the new Crazy Hotel, which opened in 1927; and replaced the First Crazy Hotel, which had burned in 1925. Mr. Griffith, who produced silent movies including the "Keystone Kops" comedies, and the classic film "Birth of a Nation", was a guest at the Crazy Hotel while visiting Mineral Wells in 1929. A commemorative postage stamp was issued in his honor on May 27, 1975. Local folklore has it that Mr. Griffith was impressed by the "WELCOME" sign on East Mountain (the world's largest non-commercial, electrically-lighted sign at the time). He developed the "HOLLYWOOD HILLS" addition with other partners when he returned to California, and he erected what is probably the most recognizable landmark in America: The HOLLYWOOD sign now graces Los Angeles. Both signs have survived similar difficult times in their histories. This picture appears on page 19 of A.F. Weaver's "TIME WAS in Mineral Wells", second edition, 1974.

CONTAIN assessment of the NUPEC mixing experiments (open access)

CONTAIN assessment of the NUPEC mixing experiments

The ability of the CONTAIN code to predict the thermal hydraulics of five experiments performed in the NUPEC 1/4-scale model containment was assessed. These experiments simulated severe accident conditions in a nuclear power plant in which helium (as a nonflammable substitute for hydrogen) and steam were coinjected at different locations in the facility with and without the concurrent injection of water sprays in the dome. Helium concentrations, gas temperatures and pressures, and wall temperatures were predicted and compared with the data. The use of different flow solvers, nodalization schemes, and analysis methods for the treatment of water sprays was emphasized. As a result, a general procedure was suggested for lumped-parameter code analyses of problems in which the thermal hydraulics are dominated by water sprays.

Geothermal energy in Idaho: site data base and development status (open access)

Geothermal energy in Idaho: site data base and development status

Detailed site specific data regarding the commercialization potential of the proven, potential, and inferred geothermal resource areas in Idaho are presented. To assess the potential for geothermal resource development in Idaho, several kinds of data were obtained. These include information regarding institutional procedures for geothermal development, logistical procedures for utilization, energy needs and forecasted demands, and resource data. Area reports, data sheets, and scenarios were prepared that described possible geothermal development at individual sites. In preparing development projections, the objective was to base them on actual market potential, forecasted growth, and known or inferred resource conditions. To the extent possible, power-on-line dates and energy utilization estimates are realistic projections of the first events. Commercialization projections were based on the assumption that an aggressive development program will prove sufficient known and inferred resources to accomplish the projected event. This report is an estimate of probable energy developable under an aggressive exploration program and is considered extremely conservative. (MHR)

Health effects model for nuclear power plant accident consequence analysis. Part I. Introduction, integration, and summary. Part II. Scientific basis for health effects models

Analysis of the radiological health effects of nuclear power plant accidents requires models for predicting early health effects, cancers and benign thyroid nodules, and genetic effects. Since the publication of the Reactor Safety Study, additional information on radiological health effects has become available. This report summarizes the efforts of a program designed to provide revised health effects models for nuclear power plant accident consequence modeling. The new models for early effects address four causes of mortality and nine categories of morbidity. The models for early effects are based upon two parameter Weibull functions. They permit evaluation of the influence of dose protraction and address the issue of variation in radiosensitivity among the population. The piecewise-linear dose-response models used in the Reactor Safety Study to predict cancers and thyroid nodules have been replaced by linear and linear-quadratic models. The new models reflect the most recently reported results of the follow-up of the survivors of the bombings of Hiroshima and Nagasaki and permit analysis of both morbidity and mortality. The new models for genetic effects allow prediction of genetic risks in each of the first five generations after an accident and include information on the relative severity of various classes of genetic …

Ceramic and glass radioactive waste forms (open access)

Ceramic and glass radioactive waste forms

This report contains 14 individual presentations and 6 group reports on the subject of glass and polycrystalline ceramic radioactive waste forms. It was the general consensus that the information available on glass as a waste form provided a good basis for planning on the use of glass as an initial waste form, that crystalline ceramic forms could also be good waste forms if much more development work were completed, and that prediction of the chemical and physical stability of the waste form far into the future would be much improved if the basic synergistic effects of low temperature, radiation and long times were better understood. Continuing development of the polycrystalline ceramic forms was recommended. It was concluded that the leach rate of radioactive species from the waste form is an important criterion for evaluating its suitability, particularly for the time period before solidified waste is permanently placed in the geologic isolation of a Federal repository. Separate abstracts were prepared for 12 of the individual papers; the remaining two were previously abstracted.

Neutron spectrum measurements for radiation protection purposes (open access)

Neutron spectrum measurements for radiation protection purposes

The energy spectra of low-intensity neutron sources used for calibrating personnel neutron dose-rate meters and dosimeters and for characterizing the neutron fields to which personnel are exposed were measured. Several detector-analyzer systems that will measure in the energy range 50 keV to 20 MeV at intensities from 10/sup -1/ to 10/sup 5/ n/cm/sup 2/-s are described. The systems include NE213 and stilbene organic scintillators as well as H/sub 2/, /sup 3/He, and CH/sub 4/ proportional counters. Also described are pulse-height analysis and pulse-shape discrimination systems. An unfolding code, NUTSPEC, reduces the pulse-height data to an absolute differential neutron flux phi(E) for the above detectors. The code uses a derivative unfolding method for the scintillation detectors, and for the proportional counters it calculates a response matrix and uses an iterative unfolding method to determine phi(E). The unfolded flux distribution combined with published conversion factors produces differential neutron dose-equivalent and kerma rates. Spectral segments obtained with different detectors from several measurements merge into a single differential flux spectrum over the range 50 keV to 20 MeV, together with the corresponding differential kerma and neutron dose-equivalent distributions. Also reported are spectrum measurements near /sup 252/Cf and /sup 238/PuBe sources with various moderators.

Field tests to determine scaling tendency of some moderate-temperature geothermal brines (open access)

Field tests to determine scaling tendency of some moderate-temperature geothermal brines

Several field tests were completed to determine the scaling tendency of moderate-temperature geothermal brines. Data were taken on the Heber as well as the East Mesa Known-Geothermal-Resources-Areas (KGRA's). The test results most directly benefit the Heber Geothermal Binary Demonstration Plant, but some have been generalized to be useful for other moderate-temperature (302 to 460/sup 0/F (150 to 239/sup 0/C)) geothermal reservoirs also. Field experiments determined conditions under which calcite, silica, and metal sulfides are likely to form. The calcite tests determined pressures which must be maintained to prevent gas-breakout and ensuing calcite deposition. Required pressures varied from one reservoir to the next and were strong functions of non-condensable gas content. The brine cooling tests tried to quantify the amount of silica which would drop out of the Heber brine by incrementally cooling it below a design set point of 150/sup 0/F (66/sup 0/C). The conclusion was that no detectable increase in silica occurred in times relevant to plant operations when the brine was cooled to 120/sup 0/F (49/sup 0/C). Although the cooling tests showed no detectable increase in silica formation, other materials did form in small amounts. The list includes magnetite (Fe/sub 3/O/sub 4/), calcite (CaCO/sub 3/), and mixtures of …

Rapid sulfur capture studies at high temperatures (open access)

Rapid sulfur capture studies at high temperatures

Determine conditions that would reproduce optimum sulfur capture ( super-equilibrium'') behavior. No attempt was made to extract kinetic data for calcination or sulfur capture, as might be done in a comprehensive study of sorbent behavior. While some interesting anomalies are present in the calcination data and in the limited surface area data, no attempt was made to pursue those issues. Since little sulfur capture was observed at operating conditions where super-equilibrium'' might be expected to occur, tests were stopped when the wide range of parameters that were studied failed to produce significant sulfur capture via the super-equilibrium mechanism. Considerable space in this report is devoted to a description of the experiment, including details of the GTRC construction. This description is included because we have received requests for a detailed description of the GTRC itself, as well as the pressurized dry powder feed system. In addition, many questions about accurately sampling the sulfur species from a high-temperature, high-pressure reactor were raised during the course of this investigation. A full account of the development of the gas and particulate sampling train in thus provided. 8 refs., 17 figs., 2 tabs.

Welcome Sign And Lookout Tower: 1929

Welcome Sign And Lookout Tower: 1929

The WELCOME sign was donated to the city of Mineral Wells in 1922 by George Holmgren, President of the Texas Rotary Club, in appreciation for the hospitality extended the Rotary Club at its State Convention in Mineral Wells that year. The caption on the photograph reads: "Reputed to be the largest Non-commercial electric sign in U.S." East Mountain was a popular place for viewing the city, especially for photographers. The lookout tower atop West Mountain (above the WELCOME sign) was destroyed by a tornado in 1930. The WELCOME Sign was built by Holmgren in his San Antonio Iron Works in 1922. He gave the sign to the people of Mineral Wells with the understanding that they would maintain the sign and the many light bulbs required to light it. The Mineral Wells Jaycees later replaced the light bulbs with lower-maintenance red neon lights. A Warrant Officer Club Company from Fort Wolters moved the sign from East Mountain in 1972 to the east side of Bald Mountain, where it remains today [2008], lighted with flood lights at its base. It is reported that this sign inspired D.W. Griffith, to promote possibly the most recognizable landmark in the United States, the HOLLYWOOD …

Griffith Energy Project Final Environmental Impact Statement (open access)

Griffith Energy Project Final Environmental Impact Statement

Griffith Energy Limited Liability Corporation (Griffith) proposes to construct and operate the Griffith Energy Project (Project), a natural gas-fuel, combined cycle power plant, on private lands south of Kingman, Ariz. The Project would be a ''merchant plant'' which means that it is not owned by a utility and there is currently no long-term commitment or obligation by any utility to purchase the capacity and energy generated by the power plant. Griffith applied to interconnect its proposed power plant with the Western Area Power Administration's (Western) Pacific Northwest-Pacific Southwest Intertie and Parker-Davis transmission systems. Western, as a major transmission system owner, needs to provide access to its transmission system when it is requested by an eligible organization per existing policies, regulations and laws. The proposed interconnection would integrate the power generated by the Project into the regional transmission grid and would allow Griffith to supply its power to the competitive electric wholesale market. Based on the application, Western's proposed action is to enter into an interconnection and construction agreement with Griffith for the requested interconnections. The proposed action includes the power plant, water wells and transmission line, natural gas pipelines, new electrical transmission lines and a substation, upgrade of an existing …
