Generic Guide Specification for Geothermal Heat Pump Systems (open access)

Generic Guide Specification for Geothermal Heat Pump Systems

The attached Geothermal (Ground-Source) Heat Pump (GHP) Guide Specifications have been developed by Oak Ridge National Laboratory (ORNL) with the intent to assist federal agency sites and engineers in the preparation of construction specifications for GHP projects. These specifications have been developed in the industry-standard Construction Specification Institute (CSI) format and cover several of the most popular members of the family of GHP systems. These guide specifications are applicable to projects whether the financing is with conventional appropriations, arranged by GHP specialty ESCOs under the U.S. Department of Energy's Technology-Specific GHP Super ESPCs, arranged by utilities under Utility Energy Service Contracts (UESCs) or arranged by generalist ESCOs under the various regional ESPCs. These specifications can provide several benefits to the end user that will help ensure successful GHP system installations. GHP guide specifications will help to streamline the specification development, review, and approval process because the architecture and engineering (AE) firm will be working from the familiar CSI format instead of developing the specifications from other sources. The guide specifications help to provide uniformity, standardization, and consistency in both the construction specifications and system installations across multiple federal sites. This standardization can provide future benefits to the federal sites in …

Plutonium Finishing Plant (PFP) Standby Power System Commercial Grade Item (CGI) Critical Characteristics (open access)

Plutonium Finishing Plant (PFP) Standby Power System Commercial Grade Item (CGI) Critical Characteristics

PFP's Standby Power System consists of the diesel generators, the generator control system, Rm 308 UPS, switchgear batteries, and the electrical equipment used to distribute this power. Due to the nature of the equipment and its use throughout general industry, the majority of the system falls within the CGI definition HNF-PRO-268, ''Control of Purchased Items and Services'' and HNF-PRO-1819, ''PHMC Engineering Requirements'' require that the critical characteristics of CGI-procured equipment be established in an engineering document prior to placing the order. HNF-5043 established these critical characteristics for the Standby Power System. This modification adds several items to the document.

Modeling of lead-acid battery capacity loss in a photovoltaic application (open access)

Modeling of lead-acid battery capacity loss in a photovoltaic application

The authors have developed a model for the probabilistic behavior of a rechargeable battery acting as the energy storage component in a photovoltaic power supply system. Stochastic and deterministic models are created to simulate the behavior of the system components. The components are the solar resource, the photovoltaic power supply system, the rechargeable battery, and a load. One focus of this research is to model battery state of charge and battery capacity as a function of time. The capacity damage effect that occurs during deep discharge is introduced via a non-positive function of duration and depth of deep discharge events. Because the form of this function is unknown and varies with battery type, the authors model it with an artificial neural network (ANN) whose parameters are to be trained with experimental data. The battery capacity loss model will be described and a numerical example will be presented showing the predicted battery life under different PV system use scenarios.

Geographic resolution issues in RAM transportation risk analysis (open access)

Geographic resolution issues in RAM transportation risk analysis

Over the years that radioactive material (RAM) transportation risk estimates have been calculated using the RADTRAN code, demand for improved geographic resolution of route characteristics, especially density of population neighboring route segments, has led to code improvements that provide more specific route definition. With the advent of geographic information systems (GISs), the achievable resolution of route characteristics is theoretically very high. The authors have compiled population-density data in 1-kilometer increments for routes extending over hundreds of kilometers without impractical expenditures of time. Achievable resolution of analysis is limited, however, by the resolution of available data. U.S. Census data typically have 1-km or better resolution within densely-populated portions of metropolitan areas but census blocks are much larger in rural areas. Geographic resolution of accident-rate data, especially for heavy/combination trucks, are typically tabulated on a statewide basis. These practical realities cause one to ask what level(s) of resolution may be necessary for meaningful risk analysis of transportation actions on a state or interstate scale.

Proceedings of the 1999 Oil and Gas Conference: Technology Options for Producer Survival

The 1999 Oil & Gas Conference was cosponsored by the U.S. Department of Energy (DOE), Office of Fossil Energy, Federal Energy Technology Center (FETC) and National Petroleum Technology Office (NPTO) on June 28 to 30 in Dallas, Texas. The Oil & Gas Conference theme, Technology Options for Producer Survival, reflects the need for development and implementation of new technologies to ensure an affordable, reliable energy future. The conference was attended by nearly 250 representatives from industry, academia, national laboratories, DOE, and other Government agencies. Three preconference workshops (Downhole Separation Technologies: Is it Applicable for Your Operations, Exploring and developing Naturally Fractured Low-Permeability Gas Reservoirs from the Rocky Mountains to the Austin Chalk, and Software Program Applications) were held. The conference agenda included an opening plenary session, three platform sessions (Sessions 2 and 3 were split into 2 concurrent topics), and a poster presentation reception. The platform session topics were Converting Your Resources Into Reserves (Sessions 1 and 2A), Clarifying Your Subsurface Vision (Session 2B), and High Performance, Cost Effective Drilling, Completion, Stimulation Technologies (Session 3B). In total, there were 5 opening speakers, 30 presenters, and 16 poster presentations.

Baryon stopping and hadronic spectra in Pb-Pb collisions at 158 GeV/nucleon (open access)

Baryon stopping and hadronic spectra in Pb-Pb collisions at 158 GeV/nucleon

Baryon stopping and particle production in Pb+Pb collisions at 158 GeV/nucleon are studied as a function of the collision centrality using new proton, antiproton, charged kaon and charged pion production data measured with the NA49 experiment at the CERN Super Proton Synchrotron (SPS). Stopping, which is measured by the shift in rapidity of net protons or baryons from the initial beam rapidity, increases in more central collisions. This is expected from a geometrical picture of the collisions. The stopping data are quantitatively compared to models incorporating various mechanisms for stopping. In general, microscopic transport calculations which incorporate current theoretical models of baryon stopping or use phenomenological extrapolations from simpler systems overestimate the dependence of stopping on centrality. Approximately, the yield of produced pions scales with the number of nucleons participating in the collision. A small increase in yield beyond this scaling, accompanied by a small suppression in the yield of the fastest pions, reflects the variation in stopping with centrality. Consistent with the observations from central collisions of light and heavy nuclei at the SPS, the transverse momentum distributions of all particles are observed to become harder with increasing centrality. This effect is most pronounced for the heaviest particles. This …
