Final safety analysis report for the Galileo mission: Volume 3 (Book 1), Nuclear risk analysis document: Revision 1

It is the purpose of the NRAD to provide an analysis of the range of potential consequences of accidents which have been identified that are associated with the launching and deployment of the Galileo mission spacecraft. The specific consequences analyzed are those associated with the possible release of radioactive material (fuel) of the Radioisotope Thermoelectric Generators (RTGs). They are in terms of radiation doses to people and areas of deposition of radioactive material. These consequence analyses can be used in several ways. One way is to identify the potential range of consequences which might have to be dealt with if there were to be an accident with a release of fuel, so as to assure that, given such an accident, the health and safety of the public will be reasonably protected. Another use of the information, in conjunction with accident and release probabilities, is to estimate the risks associated with the mission. That is, most space launches occur without incident. Given an accident, the most probable result relative to the RTGs is complete containment of the radioactive material. Only a small fraction of accidents might result in a release of fuel and subsequent radiological consequences. The combination of probability with …

Bose-Einstein correlations of pions in e/sup +/e/sup minus/ annihilation at 29 GeV center-of-mass energy (open access)

Bose-Einstein correlations of pions in e/sup +/e/sup minus/ annihilation at 29 GeV center-of-mass energy

Measurements of two- and three-particle correlations between like-sign pions produced in e/sup +/e/sup minus/ annihilation at 29 GeV center-of-mass energy are presented. The analysis is based on data taken during the period 1982--1986 using the TPC/2..gamma.. detector at PEP. Two-particle correlations are studied as a function of Q, the momentum difference as measured in the rest frame of the pion pair, and as a function of q/sub 0/, the energy difference as measured in the lab frame. The Bose-Einstein enhancement is observed when Q is small even when the energy difference, q/sub 0/, is substantial. This observation provides evidence that the Bose-Einstein correlations are best described by a model that correctly accounts for the relativistic motion of the particle sources. Three-pion correlations are measured both by using a standard three-pion correlation function, and also by using a correlation function for which the correlations between the pairs of pions within the triplet have been subtracted. The observation of three-pion correlations after pair correlations have been subtracted supports the interpretation that the observed correlations are due to Bose-Einstein interference. 56 refs.

Bacteria transport through porous material: Final technical report (open access)

Bacteria transport through porous material: Final technical report

The injection and penetration of bacteria into a reservoir is the most problematic and crucial of the steps in microbial enhanced recovery (MEOR). In the last phase of our work valuable information on bacterial transport in porous media was obtained. A great deal of progress was made to determine chemical bonding characteristics between adsorbed bacteria and the rock surfaces. In order to further enhance our knowledge of the effects of surface tensions on bacteria transport through porous media, a new approach was taken to illustrate the effect of liquid surface tension on bacterial transport through a sandpack column. Work in surface charge characterization of reservoir rock as a composite oxide system was also accomplished. In the last section of this report a mathematical model to simulate the simultaneous diffusion and growth of bacteria cells in a nutrient-enriched porous media is proposed.

Comments on new technical and economic data available for EPA`s proposed offshore oil and gas discharge guidelines and standards (open access)

Comments on new technical and economic data available for EPA`s proposed offshore oil and gas discharge guidelines and standards

The purpose of this paper is to provide comments on the Environmental Protection Agency (EPA) Notice in the Federal Register entitled, ``Oil and Gas Extraction Point Source Category, Offshore Subcategory; Effluent Limitations Guidelines and New Source Performance Standards; New Information and Request or Comments`` (53 FR 41356; October 21, 1988). This Notice announces the availability of new technical, economic and environmental assessment information relating to the development of Best Available Technology economically achievable (BAT and New Source Performance Standards (NSPS) regulations under the Clean Water Act governing the discharge of drilling fluids (muds) and drill cuttings from offshore oil and gas facilities. The Notice is part of a rulemaking process which formally began with the initial release of rules in August 1985 and which incorporates numerous comments and additional data received subsequent to the release of the 1985 rules. The comments in this paper will concentrate on the following five issues: Estimated project impacts are misrepresented by assuming weighted-average incremental costs of regulation. Economic impacts are inaccurate, since annual compliance costs will likely affect the number of wells drilled, by the effect of compliance costs on project economics and the reduction in industry cash flows on capital available for drilling. …

The economic impact of proposed regulations on the discharge of drilling muds and cuttings from the offshore facilities on US undiscovered crude oil reserves (open access)

The economic impact of proposed regulations on the discharge of drilling muds and cuttings from the offshore facilities on US undiscovered crude oil reserves

This paper presents the results of an assessment of the potential economic impact of proposed regulations. on the discharge of drilling fluids (muds) and cuttings on US offshore undiscovered crude oil resources. These regulations include proposed Best Available Technology economically achievable (BAT) and New Source Performance Standards (NSPS) effluent limitations under the Clean Water Act governing the discharge of drilling fluids and drill cuttings from offshore oil and gas drilling operations. The impact of the proposed RAT/NSPS regulations for the drilling fluids and drill cuttings disposal on the cost of funding, developing, and producing Lower-48 offshore undiscovered crude oil resources will depend significantly on operators perceptions on the chances of failing toxicity or static sheen tests. If operators, in economically justifying their projects, assume that the fluids fail one of these tests, thereby prohibiting them from being discharged, up to 11% of the economically recoverable offshore resource would be considered uneconomic to produce. This would amount to 845 million barrels of oil at an oil price around $25 per barrel. On the other hand, if operators are willing co take their chances and see if their fluids fail one of these tests, then, based on EPA`s assumptions concerning forecast fluid …
