CASIM predictions of Meson West Tevatron target soil activation (open access)

CASIM predictions of Meson West Tevatron target soil activation

A new Meson West Target has been proposed for Tevatron II. The dump design proposed by David Eartly is shown. A longitudinal side view of the dump and the shield for target produced muons is shown. The core of the dump is seen to be a copper plate surrounding the beam. The copper is surrounded by iron, which is in turn shielded by concrete. The tunnel is embedded in sand and gravel. The sand and gravel within 3' of the concrete is continuously drained by underdrains. Soil below the top of the underdrains is not considered to be protected. Activity produced in the unprotected soil below can be leached out, transported to the aquifer, and subsequently reach public water supplies. It is the activation of this unprotected soil which is of particular interest. Since the specific type of beryllium target to be used has not yet been decided, and since it would only reduce the resultant soil activation, I have chosen to ignore it and to presume that all the targetted intensity is lost on the dump. I have made CASIM calculations of the levels of soil activation to be expected using the proposed dump design. Since the activation of …

Flat-Rate Tax Proposals (open access)

Flat-Rate Tax Proposals

In recent months there has been a growing congressional interest in the advantages and disadvantages of revamping our current tax system for a flat-rate tax method. Supporters of the new proposal argue that such a plan would promote productivity, simplify present IRS tax forms, save the public billions of dollars that presently go to tax-preparation professionals, and enhance Federal revenue by closing numerous tax loopholes and special deductions that are now enjoyed by relatively few. Opponents believe, however, that the tax burden under a flat-rate plan might fall more heavily upon the middle class and, unless exceptions were made, would hurt educational institutions and charities. Problems with popular tax deductions, such as home mortgage interest, would have to be addressed. This packet provides background materials which discuss the practical and theoretical issues that surround a flat-rate tax, including the probable redistribution of the tax burden under various rates and income bases.

Innovative Rates Program. Final report (open access)

Innovative Rates Program. Final report

Title II of the Energy Conservation and Production Act (ECPA) as amended by the Public Utility Regulatory Policies Act (PURPA) provided financial assistance to state utility regulatory commissions, nonregulated electric utilities, and the Tennessee Valley Authority through the Innovative Rates Program. The financial assistance was to be used to plan or carry out electric utility regulatory rate reform initiatives relating to innovative rate structures that encourage conservation of energy, electric utility efficiency and reduced costs, and equitable rates to consumers. The Federal and local objectives of the project are described. Activities planned and accomplishments are summarized for the following: project management, data collection, utility bill evaluation, billing enclosure/mailing evaluation, media program evaluation, display evaluation, rate study sessions evaluation, speakers bureau evaluation, and individual customer contacts. A timetable/milestone chart and financial information are included. (MHR)

Modal photon densities (open access)

Modal photon densities

The short wavelength laser code XRASER uses line raidation fields whose dimensions are photons/mode. In this document, we discuss modal photon densities and provide formulas relating these units to units more familiar to the LLNL community.

Plutonium-aerosol emission rates and human pulmonary deposition calculations for Nuclear Site 201, Nevada Test Site (open access)

Plutonium-aerosol emission rates and human pulmonary deposition calculations for Nuclear Site 201, Nevada Test Site

This study determined the plutonium-aerosol fluxes from the soil to quantify (1) the extent of potential human exposure by deep-lung retention of alpha-emitting particles; (2) the source term should there be any significant, long-term, transport of plutonium aerosols; and (3) the resuspension factor and rate so that, for the first time at any nuclear site, one may calculate how long it will take for wind erosion to carry away a significant amount of the contaminated soil. High-volume air samplers and cascade impactors were used to characterize the plutonium aerosols. Meteorological flux-profile methods were used to calculate dust and plutonium aerosol emission rates. A floorless wind tunnel (10-m long) was used to examine resuspension under steady-state, high wind speed. The resuspension factor was two orders of magnitude lower than the other comparable sites at NTS and elsewhere, and the average resuspension rate of 5.3 x 10/sup -8//d was also very low, so that the half-time for resuspension by wind erosion was about 36,000 y.

SLC ir conceptual design (open access)

SLC ir conceptual design

Work on a one interaction-region, push-pull conceptual design for the SLC is described. The concept which has received the most attention is described. It is a below-ground hall - a 15 m deep rectangular pit covered by a surface building which houses counting rooms, power supplies, cryogenics and other auxiliary equipment. (LEW)
