Numerical experiments on the probability of seepage intounderground openings in heterogeneous fractured rock

Description: An important issue for the performance of underground nuclear waste repositories is the rate of seepage into the waste emplacement drifts. A prediction of this rate is particularly complicated for the potential repository site at Yucca Mountain, Nevada, because it is located in thick, unsaturated, fractured tuff formations. Underground opening in unsaturated media might act as capillary barriers, diverting water around them. In the present work, they study the potential rate of seepage into dri… more

Solar power towers

Description: The high desert near Barstow, California, has witnessed the development of this country`s first two solar power towers. Solar One operated successfully from 1982 to 1988 and proved that power towers work efficiently to produce utility-scale power from sunlight. Solar Two was connected to the utility grid in 1996 and is operating today. Like its predecessor, Solar Two is rated at 10 megawatts. An upgrade of the Solar One plant, Solar Two demonstrates how solar energy can be stored in the form of… more

Patent Reform: Overview and Comparison of S. 507 and H.R. 400

Description: H.R. 400 and S. 507 are similar but different omnibus patent reform proposals. Both bills generally transform the Patent and Trademark Office into a government corporation; require publication of patent applications 18 months after filing, subject to certain exceptions that differ in these bills; and extend the patent term for certain delays in patent issuance. S. 507 also contains provisions on patent reexamination reform. This report summarizes and compares the bills and reviews arguments for… more

Point & Click: Internet Searching Techniques

Description: This report discusses criteria to consider when judging the quality of an internet site and the best strategies for locating information on the World Wide Web. There are two ways to search the Internet. The first is to use subject guides (e.g., Yahoo, Galaxy, or WWW Virtual Library), which are compiled by human indexers. These present an organized hierarchy of categories so a searcher can “drill down” through their links. The second option is to use a search engine (e.g., Alta Vista, Hotbot, or… more

Solar buildings. Overview: The Solar Buildings Program

Description: Buildings account for more than one third of the energy used in the United States each year, consuming vast amounts of electricity, natural gas, and fuel oil. Given this level of consumption, the buildings sector is rife with opportunity for alternative energy technologies. The US Department of Energy`s Solar Buildings Program was established to take advantage of this opportunity. The Solar Buildings Program is engaged in research, development, and deployment on solar thermal technologies, whic… more

Solar dish/engine systems

Description: Solar dish/engine systems convert the energy from the sun into electricity at a very high efficiency. Using a mirror array formed into the shape of a dish, the solar dish focuses the sun`s rays onto a receiver. The receiver transmits the energy to an engine that generates electric power. Because of the high concentration ratios achievable with parabolic dishes and the small size of the receiver, solar dishes are efficient at collecting solar energy at very high temperatures. Tests of prototype … more

1997 annual report on waste generation and waste minimization progress as required by DOE Order 5400.1, Hanford Site

Description: Hanford`s missions are to safely clean up and manage the site`s legacy wastes, and to develop and deploy science and technology. Through these missions Hanford will contribute to economic diversification of the region. Hanford`s environmental management or cleanup mission is to protect the health and safety of the public, workers, and the environment; control hazardous materials; and utilize the assets (people, infra structure, site) for other missions. Hanford`s science and technology mission … more

Tank characterization technical sampling basis

Description: Tank Characterization Technical Sampling Basis (this document) is the first step of an in place working process to plan characterization activities in an optimal manner. This document will be used to develop the revision of the Waste Information Requirements Document (WIRD) (Winkelman et al. 1997) and ultimately, to create sampling schedules. The revised WIRD will define all Characterization Project activities over the course of subsequent fiscal years 1999 through 2002. This document establish… more

Solar Two

Description: Solar Two is a concentrating solar power plant that can supply electric power on demand to the local utility, Southern California Edison Company. It can do so because it operates not only during sunny parts of the day, but it can store enough thermal energy from the sun to operate during cloudy periods and after dark, for up to three hours, at its rated output of 10 megawatts (MW). For the first time ever, a utility scale solar power plant can supply electricity when the utility needs it most, … more

Helium Background in the D0 Detector Related to the Photomultiplier Tubes

Description: Helium is present in the earth's atmosphere at about 5 parts per million. (ref. Technology of liquid helium, NBS monograph 111). The D-Zero detector uses helium for the cryogenic cooling of its superconducting magnet and visible light photon counter (VLPC) electronics chips. In addition, the tevatron accelerator has superconducting magnets that use helium Due to the possibility of leaks or releases of helium from these helium lines and components, the background helium level in the collision ha… more
