Testimony by J. William Currie, Ph. D Manager, Energy Systems Modernization Office, Battelle, Pacific Northwest Laboratories before The Senate Committee on Governmental Affairs Washington D. C

This report consists of the testimony by J. William Currie, Manager, Energy Systems Modernization Office, Battelle, Pacific Northwest Laboratories before The Senate Committee on Governmental Affairs, Washington, DC on February 18, 1992. He states It is a pleasure to have the opportunity to talk with this distinguished committee about energy conservation technologies and policies, especially as they relate to federal energy use and the commercialization of energy-efficiency technologies. Clearly, using energy more efficiently offers the potential for tremendous cost savings and environmental benefits in the United States and throughout the rest of the world. The challenge, especially with regard to the federal sector, is to lay the foundation for ensuring that the citizens of our nation realize the maximum savings and environmental benefit over the long run. This is the primary focus of my comments today.''

Substitute safety rods: Physics of operation and irradiation (open access)

Substitute safety rods: Physics of operation and irradiation

Under certain assumed accidents, an SRS reactor may lose most of its bulk moderator while maintaining flow to fuel assemblies. If this occurs immediately after operation at power, components normally dependent on convective heat transfer to the moderator will heat up with the possibility of melting that component. One component at risk is the currently used cadmium safety rod. A substitute safety rod consisting solely of sintered B{sub 4}C and stainless steel has been designed which is capable of withstanding much higher temperatures. This memorandum provides the physics basis for the adequacy of the rod for reactor shutdown and provides a set of criteria for acceptance in the NTG tests. This memorandum provides physics data for other aspects of operation. These include: Heat production and helium production, along with related phenomena, resulting from inadvertent irradiation at power. Gamma heat input under drained tank conditions. An equivalent rod design suitable for charge design and safety analyses. Degradation under normal operation. Thermal flux ripple in adjacent fuel due to axial striping of alternate B{sub 4}C and steel pellets. Possible effect on safety analyses. Safety rod withdrawal during reactor startup.

Theoretical approach for enhanced mass transfer effects in-duct flue gas desulfurization processes (open access)

Theoretical approach for enhanced mass transfer effects in-duct flue gas desulfurization processes

Bench-scale and pilot-scale experiments have been conducted to measure the mass transfer and kinetic rates at simulated duct injection conditions. Section 2 describes the tank reactor test results. The stirred tank reactor was used to study absorption of SO{sub 2} into saturated Ca(OH){sub 2} solutions with varied ionic strengths. The results of current experiments were compared with previous tests using saturated Ca(OH){sub 2} solution and 0.1 M CaCl{sub 2}. Section 3 summarizes the status of the Short-Time Differential Reactor (STDR) tests for Task 2.3. The effect of CO{sub 2} on reactivity of Mississippi Ca(OH){sub 2} with SO{sub 2} was investigated. The extent of carbonation was measured for a commercial Mississippi Ca(OH){sub 2} and laboratory-produced sorbents. Section 4 presents pilot plant testing conducted to evaluate various operating conditions and process schemes to support large-scale field testing at Meredosia and Beverly (Task 3). Consistent data were obtained from pilot testing of in-duct dry injection downstream of the humidifier. Section 5 reports differential reactor (Task 4) tests. The differential reactor has been modified to determine the effect of initial water content on the sorbent reactivity. An experimental method has been developed to prepare solid samples containing reproducible, predictable quantities of water. The experiments …

SEPARATION OF TRITIATED WATER FROM WATER USING COMPOSITE MEMBRANES

The work in this task involves the use of composite membranes to remove tritium from contaminated water at DOE sites. Experience with membrane systems in industry indicates that they are inherently energy efficient. Furthermore, membrane technologies such as reverse-osmosis have been well developed for desalination and other industrial/municipal applications. Aromatic polyphosphazenes were chosen as the polymeric material for the membranes being investigated because they have excellent radiological, thermal, and chemical stability. The FY-96 effort is directed toward empirical delineation of a potential mechanism, providing a statistical approach to data acquisition, further mass balance determination, and a preliminary design for the module staged array.

A new transport discretization scheme for arbitrary spatial meshes in XY geometry (open access)

A new transport discretization scheme for arbitrary spatial meshes in XY geometry

We introduce a new spatial discretization scheme for transport on arbitrary spatial grids in XY geometry. Our arbitrary'' spatial grid is composed of arbitrarily-connected polygons, each of which may have an arbitrary number of sides. We begin our derivation by imposing particle balance on every corner'' of each cell (Consequently, we call our scheme the corner-balance (CB) method.) We complete the derivation by introducing simple closure formulas that relate volume-averaged unknowns to surface-averaged unknowns in each corner. We discuss the relationship of the new scheme to discontinuous finite-element methods and to multiple-balance methods. We demonstrate that on simple grids, the method reduces to very robust schemes that have been studied previously. We discuss the theoretical performance of the method in the thick diffusion limit, and provide numerical results for that limit. We present additional numerical results from simple problems that test the new scheme in other limits. Finally, we offer some concluding remarks about the method. 9 refs., 6 figs.

The European nuclear power industry: Restructuring for combined strength and worldwide leadership

The European nuclear power industry is being restructured from an industry drawn along national lines to a European-wide industry. This, in part, reflects growth of the European Economic Community, but it also reflects changes in the international nuclear power industry. The objectives of the participants, beyond better integration of the nuclear industry in Western Europe, are to (1) obtain European leadership of the worldwide commercial nuclear power industry, (2) improve medium- and long-term safety of Eastern Europe and the former Soviet Union (FSU) power reactors, and (3) reduce domestic concerns about nuclear power. The activities to achieve these goals include (1) formation of Nuclear Power International (a joint venture of the German and French nuclear power plant vendors for design and construction of nuclear power plants), (2) formation of a utility group to forge agreement throughout Europe on what the requirements are for the next generation of nuclear power plants, and (3) agreement by regulators in multiple European countries to harmonize regulations. This is to be achieved before the end of the decade. These changes would allow a single design of nuclear power plant to be built anywhere in Europe.

Optically-ionized plasma recombination x-ray lasers (open access)

Optically-ionized plasma recombination x-ray lasers

Design studies for recombination x-ray lasers based on plasmas ionized by high intensity, short pulse optical lasers are presented. Transient lasing on n = 3 to n = 2 transitions in Lithium-like Neon allows for moderately short wavelengths ({le} 100{angstrom}) without requiring ionizing intensities associated with relativistic electron quiver energies. The electron energy distribution following the ionizing pulse affects directly the predicted gains for this resonance transition. Efficiencies of 10{sup {minus}6} or greater are found for plasma temperatures in the vicinity of 40 eV. Simulation studies of parametric heating phenomena relating to stimulated Raman and Compton scattering are presented. For electron densities less than about 2.5 {times} 10{sup 20} cm{sup {minus}3} and peak driver intensity of 2 {times} 10{sup 17} W/cm{sup 2} at 0.25 {mu}m with pulse length of 100 fsec, the amount of electron heating is found to be marginally significant. For Lithium-like Aluminum, the required relativistic ionizing intensity gives excessive electron heating and reduced efficiency, thereby rendering this scheme impractical for generating shorter wavelength lasing ({le} 50{angstrom}) in the transient case. Following the transient lasing phase, a slow hydrodynamic expansion into the surrounding cool plasma is accompanied by quasi-static gain on the n = 4 to n = …

Evaluation of the computerized utilities energy monitoring and control system installed at the US Military Community at Goeppingen, Germany

Under the provisions of an Interagency Agreement between the US Army and the Department of Energy, Martin Marietta Energy Systems, Inc., through the Oak Ridge National Laboratory, is evaluating the Utilities and Energy Monitoring and Control System (UEMCS) installed at the US Military Community Activity at Goeppingen, Germany. This evaluation relies on examination of existing data and information to determine the effectiveness of the UEMCS. The Goeppingen UEMCS is an integral part of a combined UEMCS/district heating system which includes the UEMCS at Schwaebisch Gmuend, Germany. The system was installed during 1985 and 1986. The UEMCS at Goeppingen and Schwaebisch Gmuend are both well designed, implemented, and maintained. The UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS is operated in a supervisory mode with distributed intelligence in local controllers. At present, the UEMCS at Schwaebisch Gmuend does not have a central computer, but requires only a dedicated phone line to couple with the one at Goeppingen. Though the conversion to district heat has produced the majority of energy savings, the UEMCS day/night setback program also contributes substantially, with additional savings from start/stop programs, such as seasonal switchover, and various temperature control …
