Westinghouse independent safety review of Savannah River production reactors (open access)

Westinghouse independent safety review of Savannah River production reactors

Westinghouse Electric Corporation has performed a safety assessment of the Savannah River production reactors (K,L, and P) as requested by the US Department of Energy. This assessment was performed between November 1, 1988, and April 1, 1989, under the transition contract for the Westinghouse Savannah River Company's preparations to succeed E.I. du Pont de Nemours Company as the US Department of Energy contractor for the Savannah River Project. The reviewers were drawn from several Westinghouse nuclear energy organizations, embody a combination of commercial and government reactor experience, and have backgrounds covering the range of technologies relevant to assessing nuclear safety. The report presents the rationale from which the overall judgment was drawn and the basis for the committee's opinion on the phased restart strategy proposed by E.I. du Pont de Nemours Company, Westinghouse, and the US Department of Energy-Savannah River. The committee concluded that it could recommend restart of one reactor at partial power upon completion of a list of recommended upgrades both to systems and their supporting analyses and after demonstration that the organization had assimilated the massive changes it will have undergone.

Assessment of the theory and hypotheses of the acidification of watersheds (open access)

Assessment of the theory and hypotheses of the acidification of watersheds

This report documents and critically assesses the evolution and status of the scientific understanding of the effects of acidic deposition on surface waters. The main conclusion is that the dominant theory of surface-water acidification fails to adequately incorporate many important factors and processes that influence surface water acidity. Some of these factors and processes are not well researched or recognized as being important by most scientists in the aquatic effects research area. 258 refs., 14 figs., 23 tabs.

Simulation of ethylbenzene dehydrogenation in microporous catalytic membrane reactors (open access)

Simulation of ethylbenzene dehydrogenation in microporous catalytic membrane reactors

Current state-of-the-art inorganic oxide membranes offer the potential of being modified to yield catalytic properties. The resulting modules may be configured to simultaneously induce catalytic reactions with product concentration and separation in a single processing step. Processes utilizing such catalytically active membrane reactors have the potential for dramatically increasing yield of reactions which are currently limited by either thermodynamic equilibria, product inhibition, or kinetic selectivity. Examples of systems of commercial interest include hydrogenation, dehydrogenation, partial and selective oxidation, hydrations, hydrocarbon cracking, olefin metathesis, hydroformylation, and olefin polymerization. A large portion of the most significant reactions fall into the category of high temperature, gas phase chemical and petrochemical processes. Microporous oxide membranes are well suited for these applications. A program is proposed to investigate selected model reactions of commercial interest (i.e., dehydrogenation of ethylbenzene to styrene and dehydrogenation of butane to butadiene) using a high temperature catalytic membrane reactor. Membranes will be developed, reaction dynamics characterized, and production processes developed, culminating in laboratory-scale demonstration of technical and economic feasibility. As a result of the anticipated increased yield per reactor pass, large economic incentives are envisioned. First, a large decrease in the temperature required to obtain high yield should be possible because …

Modeling of Integrated Environmental Control Systems for Coal-Fired Power Plants Quarterly Report: January-March 1989 (open access)

Modeling of Integrated Environmental Control Systems for Coal-Fired Power Plants Quarterly Report: January-March 1989

This is the sixth quarterly report of DOE Contract No. DE-AC22- 87PC79863, entitled Modeling of Integrated Environmental Control Systems for Coal-Fired Power Plants.'' This report summarizes accomplishments during the period January 1, 1989 to March 31, 1989. Efforts this past quarter focused primarily on the preparation of a computer User's Guide for the Integrated Environmental Control Model (IECM). Drafts of the first two chapters are now complete. These chapters constitute the bulk of this quarterly report. Drafts of the remaining chapters are in preparation, and will appear in a future report this year. We also have been working closely with DOE/PETC to define the computer configuration to be transferred to PETC as a contract deliverable. That process is now complete and the equipment is on order. Delivery of the IECM to PETC is expected during the next calendar quarter. Finally, we are continuing our efforts to develop and refine a number of clean coal technology process models. These efforts will be summarized and reported at a future date.

MHD compressor---expander conversion system integrated with GCR inside a deployable reflector (open access)

MHD compressor---expander conversion system integrated with GCR inside a deployable reflector

This work originates from the proposal MHD Compressor-Expander Conversion System Integrated with a GCR Inside a Deployable Reflector''. The proposal concerned an innovative concept of nuclear, closed-cycle MHD converter for power generation on space-based systems in the multi-megawatt range. The basic element of this converter is the Power Conversion Unit (PCU) consisting of a gas core reactor directly coupled to an MHD expansion channel. Integrated with the PCU, a deployable reflector provides reactivity control. The working fluid could be either uranium hexafluoride or a mixture of uranium hexafluoride and helium, added to enhance the heat transfer properties. The original Statement of Work, which concerned the whole conversion system, was subsequently redirected and focused on the basic mechanisms of neutronics, reactivity control, ionization and electrical conductivity in the PCU. Furthermore, the study was required to be inherently generic such that the study was required to be inherently generic such that the analysis an results can be applied to various nuclear reactor and/or MHD channel designs''.

Establishment and maintenance of a coal sample bank and data base

During the current reporting period a total of 139 samples (46 DOE Sample Bank samples and 93 other Penn State samples) of various sizes were distributed. Sixty-three of the samples were distributed to DOE or its contractors; 76 were distributed to other agencies. A total of 88 data printouts were distributed. In addition, seven special data requests were fulfilled by either search/sort and printout or creation of a data disk. Several preliminary requests for Sample Bank and Data Base information have also been handled.

COMMIX analysis of four constant flow thermal upramp experiments performed in a thermal hydraulic model of an advanced LMR (open access)

COMMIX analysis of four constant flow thermal upramp experiments performed in a thermal hydraulic model of an advanced LMR

The three-dimensional thermal hydraulics computer code COMMIX-1AR was used to analyze four constant flow thermal upramp experiments performed in the thermal hydraulic model of an advanced LMR. An objective of these analyses was the validation of COMMIX-1AR for buoyancy affected flows. The COMMIX calculated temperature histories of some thermocouples in the model were compared with the corresponding measured data. The conclusions of this work are presented. 3 refs., 5 figs.

Phase formation in the Pt/InP thin film system (open access)

Phase formation in the Pt/InP thin film system

InP substrates with 40nm metal films of Pt were encapsulated in SiO{sub 2}, and isochronally annealed up to 600{degrees}C in flowing forming gas. The composition and morphology of the phases that formed were studied using x-ray diffraction, Rutherford Backscattering, and transmission electron microscopy. Results show that the Pt/InP system begins interacting at 300{degrees}C. TEM analysis of the 350{degrees}C anneal shows unreacted Pt and additional polycrystalline phases, with no observed orientation relationship with the substrate. The Pt layer has been completely consumed by 400{degrees}C, with a uniform reacted layer indicated by RBS. At high temperatures (between 500{degrees}C and 600{degrees}C), the reaction products are PtIn{sub 2} and PtP{sub 2}. The two phases show a tendency for phase separation, with a higher concentration of PtP{sub 2} at the InP/reacted layer interface. The phosphide phase also shows a preferred orientation relationship with the substrate. 14 refs., 5 figs.
