A companion paper presented at this conference described the design of a Radioisotope Thermophotovoltaic (RTPV) Generator for an illustrative space mission (Pluto Fast Flyby). It presented a detailed design of an integrated system consisting of a radioisotope heat source, a thermophotovoltaic converter, and an optimized heat rejection system. The present paper describes the thermal, electrical, and structural analyses which led to that optimized design, and compares the computed RTPV performance to that of a Radioisotope Thermoelectric Generator (RTG) designed for the same mission. RTPV's are of course much less mature than RTGs, but our results indicate that - when fully developed - they could result in a 60% reduction of the heat source's mass, cost, and fuel loading, a 50% reduction of generator mass, a tripling of the power system's specific power, and a quadrupling of its efficiency. The paper concludes by briefly summarizing the RTPV's current technology status and assessing its potential applicability for the PFF mission. For other power systems (e.g. RTGs), demonstrating their flight readiness for a long mission is a very time-consuming process to determine the long-term effect of temperature-induced degradation mechanisms. But for the case of the described RTPV design, the paper lists a number …

This program relates to demonstration use of electric-powered vehicles. KSU has two electric cars (conversion vehicles) from Soleq. Corp., and is purchasing 4 Chevy trucks for conversion. This document discusses the participating groups, program plan, events, vehicles and components, operations, and procurement.

We have determined the inelastic magnetic response S({omega}) of UPd{sub x}cu{sub 5{minus}x} (X=1,1.5) for temperatures from 0.3 to 300 K and energies between 05 and 400 meV using the neutron time of flight technique. S({omega}) is virtually identical in the two compound, displaying marginal Fermi Liquid scaling over the entire range of temperatures, as well as scale invariant energetics.

The Petroleum Supply Monthly (PSM) is one of a family of four publications produced by the Petroleum Supply Division within the Energy Information Administration (EIA) reflecting different levels of data timeliness and completeness. The other publications are the Weekly Petroleum Status Report (WPSR), the Winter Fuels Report, and the Petroleum Supply Annual (PSA). Data presented in the PSM describe the supply and disposition of petroleum products in the United States and major US geographic regions. The data series describe production, imports and exports, inter-Petroleum Administration for Defense (PAD) District movements, and inventories by the primary suppliers of petroleum products in the United States (50 States and the District of Columbia). The reporting universe includes those petroleum sectors in primary supply. Included are: petroleum refiners, motor gasoline blenders, operators of natural gas processing plants and fractionators, inter-PAD transporters, importers, and major inventory holders of petroleum products and crude oil. When aggregated, the data reported by these sectors approximately represent the consumption of petroleum products in the United States. Data presented in the PSM are divided into two sections: Summary Statistics and Detailed Statistics.

The estimate is based on the preliminary magnet design provided by B. Lundberg. The required magnetic field induction in the winding carrying toroid leg is specified as an initial condition. Based on the cross section areas of the toroid legs the induction in all four toroid legs can be calculated. The particular type of steel which will be used is unknown so they used the curve on Fig. 2 for the most wide spread steels to obtain a field strength in the steel. The number of steel plates and accordingly the resulting technological air gap are unknown, therefore the calculation for two different gaps .25 mm and 2.5 mm were preformed. Results of the power consumption calculations for the proposed toroid spoiler magnet for different magnetic field induction values and two different air gaps are given. Operating costs for running the magnet are also given.

In accordance with the past-practice strategy, the US Department of Energy (DOE) is conducting an expedited response action (ERA) at the N Springs, located in the Hanford 100 N Area. This Project Management Plan (PMP) addresses the design and construction of a sheet pile barrier and the design, construction, and operation of an ion-exchanged pump and treat system at N Springs. There were three objectives set for the N Springs ERA, which are outlined in Item 6 in the Senior Executive Agreement Committee Agreement on the Resolution of Milestone M-14-00 Change Request Dispute. The first N Springs ERA objective is to eliminate or substantially reduce the flux of strontium-90 to the N Springs, and ultimately to the Columbia River via groundwater migration. A sheet pile barrier will be installed in the path of groundwater flow, forcing strontium-90 contaminated groundwater to flow around it in order to reach the river, substantially decreasing groundwater flow velocity. Since the strontium transport velocity is approximately 2 orders of magnitude less than that of the groundwater in the vicinity, the flux of strontium-90 to the river will be reduced. The second N Springs ERA objective is to evaluate commercially available treatment options for strontium-90 contaminated …

This report analyzes the radionuclide dose impact of the PUREX process waste stream. The radionuclide ingestion and inhalation pathways are analyzed. Two spent fuel assemblies processed in the Separation facilities are analyzed, the Mark 31A and Mark 31B. The individual radionuclide significance to dose is evaluated in terms of dose percentage. Comparing the radionuclide individual dose value allows the determination of those radionuclides whose dose impact is significant. The results of this analysis demonstrate that a limited number of radionuclides contribute 1% or more to the total dose and that the major contributor to the sludge source dose is strontium. The results obtained permit reducing the list of radionuclides to be considered in the development of source terms to support the High Level Waste Safety Analysis Report.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.
