Acceptance criteria for heat exchanger head staybolts

Description: Each of the six primary coolant loop systems of the Savannah River Site production reactors contains two parallel single-pass heat exchangers to transfer heat from the primary coolant (D{sub 2}O) to the secondary cooling water (H{sub 2}O). The configuration of the heat exchangers includes a plenary space defined by the heat exchanger tubesheet and the heat exchanger head at both the heat exchanger inlet and outlet to the primary piping. The primary restraint of the heat exchanger head (Type 304… more

Accident Management to Prevent Containment Failure and Reduce Fission Product Release

Description: Brookhaven National Laboratory, under the auspices of the US Nuclear Regulatory Commission, is investigating accident management strategies which could help preserve containment integrity or minimize releases during a severe accident. The strategies considered make use of existing plant systems and equipment in innovative ways to reduce the likelihood of containment failure or to mitigate the release of fission products to the environment if failure cannot be prevented. Many of these strategies… more

Accreditation of ionizing radiation protection programs

Description: There are over one million workers in the United States who have the potential to be exposed to ionizing radiation. Therefore, it is necessary to determine accurately the quantity of radiation to which they may have been exposed. This quantity if measured by personnel dosimeters that are carried by individuals requiring radiation monitoring. Accreditation of the organizations which evaluate this quantity provides official recognition of the competence of these organizations. Accreditation progr… more

Accuracy and Cost Effectiveness of Manual and Automated Water-Level Monitoring Technology

Description: Relative water-surface elevations are used to characterize the unconfined aquifer beneath the Hanford Site. Simultaneous and frequent, measurements in areas of rapid change have been avoided because of cost, even though both are important, and in some cases essential, for aquifer characterization. The objective of this study was to evaluate, demonstrate, and report on the most cost-effective methods of obtaining water-level data for characterizing aquifers at hazardous waste sites. Aquifer char… more

Achromatic and isochronous electron beam transport for tunable free electron lasers

Description: We have continued the study of a suitable electron beam transport line, which is both isochronous and achromatic, for the free electron laser being designed at Lawrence Berkeley Laboratory. A refined version of the beam transport optics is discussed that accommodates two different modes of FEL wavelength tuning. For the fine tuning involving a small change of the electron beam energy, sextupoles are added to cancel the leading nonlinear dispersion. For the main tuning involving the change of th… more

Acid measurements via near-infrared spectroscopy

Description: We were able to predict acid concentration to {plus_minus}0.08M HNO{sub 3}. In the presence of Al{sup 3} interference, the prediction dropped to {plus_minus}0.29 mols/liter over the range 0 to 9M HNO{sub 3}. Temperature affects the prediction of acid adversely and would have to be modelled out or the sample cell thermostated prior to using this method. 10 refs, 12 figs.(DLC)

The acid precipitation provisions of the 1990 Clean Air Act Amendments and minorities' energy consumption

Description: In November 1990 Congress passed a comprehensive set of amendments to the Clean Air Act of 1977 with potentially very high compliance costs. The provisions pertaining to control of acid precipitation have been specified with sufficient detail to examine their cost impacts. These provisions will require investment in emissions control technology, mainly by electric utilities. Production costs will increase due to the required investment, resulting in higher electricity prices. This paper examine… more

Acoustic emissions applications on the NASA Space Station

Description: Acoustic emission is being investigated as a way to continuously monitor the space station Freedom for damage caused by space debris impact and seal failure. Experiments run to date focused on detecting and locating simulated and real impacts and leakage. These were performed both in the laboratory on a section of material similar to a space station shell panel and also on the full-scale common module prototype at Boeing's Huntsville facility. A neural network approach supplemented standard aco… more

Acrylic mechanical bond tests

Description: The tensile strength of bonded acrylic is tested as a function of bond joint thickness. 0.125 in. thick bond joints were found to posses the maximum strength while the acceptable range of joints varied from 0.063 in. to almost 0.25 in.

ACT sup 2 project report: Ventilation and air tightness measurement of the Sunset Building

Description: This report presents the results of ventilation and air tightness measurements made on the test section of the Sunset Building as part of the ACT{sup 2} project. Real-time measurements were made over a two-week period in July 1991 to determine the building's performance; most of the results derive from intensive measurements made during (unoccupied) weekend periods. The ventilation rate of the entire building was measured to be about 2 air changes per hour of outdoor air which exceeds ASHRAE St… more

Actinide consumption: Nuclear resource conservation without breeding

Description: A new approach to the nuclear power issue based on a metallic fast reactor fuel and pyrometallurgical processing of spent fuel is showing great potential and is approaching a critical demonstration phase. If successful, this approach will complement and validate the LWR reactor systems and the attendant infrastructure (including repository development) and will alleviate the dominant concerns over the acceptability of nuclear power. The Integral Fast Reactor (IFR) concept is a metal-fueled, sod… more
