Bench-scale co-processing. Quarterly report No. 14, October 1, 1991--December 31, 1991

Description: This report, which is the 14th quarterly report for Contract DE-AC22-87PC79818, covers the quarter from October 1991 to December 1991. The objective of this contract is to extend and optimize UOP`s single-stage, slurry-catalyzed co-processing scheme. The current task is to complete a long-term operability run using a molybdenum-based catalyst at approximately 460{degrees}C. The objectives of this study are to demonstrate that high-severity conditions can be run for an extended period (at least one month) and to collect enough product sample to do a complete Hempel fractionation and detailed characterization of the individual naphtha, distillate, and VGO cuts. This information will be used to reevaluate the engineering design and product upgrading scheme that was developed under the first co-processing contract (DE-AC22-84PC70002). During the current quarter, the long-term operability study was successful completed.

Preliminary engineer`s flow sketch and process description, Redox feed preparation from current metal

Description: The basis feed to the Redox plant is 5,000 lb/day of uranium, supplied both as current irradiated uranium metal slugs in jackets, and as uranium compounds from the existing metal waste storage tanks. The proportions of the two feeds are chosen according to the enrichment level of the irradiated metal, so as to give a plutonium production of about 650 gm/day. The design basis has been taken as 0 to 1,500 lb/day U from the waste storage system and 2,000--5,000 lb/day of irradiated metal. Only the feed preparation from irradiated metal is discussed in this process description, and a basis of 5,000 lb/day is used throughout. The metal feed has associated with it 172.5 lb. Al and 2.5 lb. Si as slug jackets, and contains about 650 gpm. plutonium and 3 {times} 10{sup 5} curies of gamma-emitting fission products (FP). The purpose of the feed preparation section is to remove the aluminum and silicon, and to dissolve the uranium as an aqueous solution for feed to the Redox extraction battery. Secondarily, it is tentatively proposed to provide equipment in this section to achieve a preliminary decontamination from ruthenium, which is poorly handled by the Redox extraction system, and from FP which are adsorbed by the filter aid used in the clarification step. The product of the feed preparation section is an aqueous solution of uranyl nitrate hexahydrate of 59.4% (2 M) concentration, with part of the stoichiometric nitrate ion neutralized by NaOH, and containing nearly 2% sodium dichromate as an oxidizing agent. It contains 99.9% of the plutonium originally in the slugs, and perhaps as little as 0.3 {times} 10{sup 5} curies of gamma-emitting FP.

K{sub effective} calculations for infinite planar square-pitched arrays of waste receptacles

Description: Neutron multiplication factors (k{sub eff}) have been calculated for arrays of three standard sizes of waste receptacles: 5, 30, and 55 gallon drums containing either 2% or 5% enriched uranium compounds mixed with either water or oil. The calculations demonstrate the effect of both the array pitch and the uranium concentration on k{sub eff} No container was subcritical for all possible sets of concentration and pitch. All were safe for both very low and very high uranium concentrations. Accident condition calculations, for which an extra drum is added to the system, show little effect on criticality.

Nitrogen oxide abatement by distributed fuel addition. Quarterly report No. 11, February 1, 1990--April 30, 1990

Description: The formation and destruction of nitrogenous species in the fuel rich coal post flame of a laboratory coal combustor were explored. The fuel rich zones in reburning and air staging configurations were compared under a variety of conditions. The objective was to determine the relative significance of homogeneous and heterogeneous sources of HCN formation and to extract models that can predict nitrogenous species profiles in fuel rich zones. Heterogeneous effects on HCN formation due to the slow release of nitrogen from the coal residue were of minor significance. HCN formation and destruction in fuel rich regimes were governed by homogeneous gas phase kinetics. The contribution of Fenimore nitrogen fixation reaction of HCN formation limited the destruction of nitrogenous species in fuel rich regimes. The interconversion of nitrogenous species in the fuel rich pulverized coal post flame could be adequately described by a simplified mechanism based on known fundamental gas phase kinetics with no adjustment of rate coefficients and partial equilibrium assumptions. The proposed model was successful at predicting NO, HCN and NH{sub 3} profiles under reducing conditions in both reburning and staged combustion configurations.

Fundamental mechanisms in flue gas conditioning. Quarterly report, July 1992--September 1992

Description: This project is divided into four tasks. We developed our management plan in Task 1. Task 2, evaluation of mechanisms in FGD sorbent and ash interactions, focuses on characteristics of binary mixtures of these distinct powders. Task 3, evaluation of mechanisms in conditioning agents and ash, is designed to examine effects of various conditioning agents on fine ash particles to determine mechanisms by which these agents alter physical properties of ash. We began Tasks 2 and 3 with an extensive literature search and assembly of existing theories. We completed this phase of the project with publication of two special Topical Reports. Our laboratory analyses during the past quarter covered a variety of topics. We quantified increases in surface area, changes in particle morphology, and increases in cohesivity that result when sorbents are mixed with ashes. Measurements of water content illustrated the increased tendency of the mixtures to adsorb and absorb water. Our analyses of leached and unleached dust cake ashes provided some interesting insights into effects that compounds adsorbed on surfaces of ash particles can have on bulk ash behavior. We also observed the effects that pozzolanic reactions can have on ash resistivity. Initial examinations of outputs of the SRI-EPA resistivity prediction model showed that the model could not accurately predict the resistivities we measured for leached and unleached dust cake ashes.

Hot semiworks Redox studies

Description: The separations Hot Semiworks at the Hanford Atomic Products Operation was built in order to: (1) develop optimum conditions for the economic operation of the Redox and TBP plants, (2) procure engineering design data which would allow the specification of process equipment required for new processes such as Purex, (3) provide facilities for the study of future process and engineering problems on a semiworks scale employing radioactive process solutions, and (4) provide facilities for immediate trouble shooting for urgent separations plant problems. The initial operation of this facility was designed to develop conditions for the economic operation of the Redox Plant. These studies, covering a period from November, 1952 to October, 1953, are described in this report. The Redox process is used at Hanford for the separation of uranium and plutonium from fission products and from each other. The basis of the process is the preferential extraction of uranium and plutonium nitrates from an aqueous phase of high salting strength into an organic solvent (methyl isobutyl ketone) to effect the separation from fission products. This operation is conducted continuously in columns, packed with Raschig rings, through which the phases are passed counter-currently. Uranium and plutonium are separated by converting the plutonium to a lower valence state, in which form it is preferentially extracted back into an aqueous phase of high salting strength in a second column. Uranium is then returned to an aqueous phase of low salting strength in a third column. The products are further decontaminated in similar additional cycles. A detailed description of the process is given in the Redox Technical Manual.

Nitrogen oxide abatement by distributed fuel addition. Quarterly report No. 3, February 1, 1988--April 30, 1988

Description: This research is directed towards the development of engineering guidelines that define the application of distributed fuel addition as a technique for NO{sub x} abatement. It is expected that multiple fuel and air addition in the post-flame of a combustion process will increase free radical concentrations which destroy nitrogenous species and thus help them decay toward their equilibrium concentrations, which can be very low in that region of the combustor. Screening experiments were conducted on a laboratory scale downfired combustor. The objective was to compare NO{sub x} emissions arising from various combustion configurations, including fuel and/or air staging. Although the primary focus of this research is on NO control, a secondary effort was directed towards the measurement of N{sub 2}O emissions from various coal combustion processes. N{sub 2}O has been identified as a trace gas responsible for stratospheric ozone depletion, and has been hypothesized to arise from combustion processes, in amounts roughly proportional to NO emissions. Results presented in this report showed that the ratio N{sub 2}O/NO was far from constant. The introduction of secondary air into a combustion process was accompanied an increase in N{sub 2}O emissions. The measured N{sub 2}O was always less than 10 ppm even under the most favorable combustion conditions. Reburning with premixed fuel and air mixtures was not effective in reducing NO emissions.

Early Site Permit Demonstration Program: Recommendations for communication activities and public participation in the Early Site Permit Demonstration Program

Description: On October 24, 1992, President Bush signed into law the National Energy Policy Act of 1992. The bill is a sweeping, comprehensive overhaul of the Nation`s energy laws, the first in more than a decade. Among other provisions, the National Energy Policy Act reforms the licensing process for new nuclear power plants by adopting a new approach developed by the US Nuclear Regulatory Commission (NRC) in 1989, and upheld in court in 1992. The NRC 10 CFR Part 52 rule is a three-step process that guarantees public participation at each step. The steps are: early site permit approval; standard design certifications; and, combined construction/operating licenses for nuclear power reactors. Licensing reform increases an organization`s ability to respond to future baseload electricity generation needs with less financial risk for ratepayers and the organization. Costly delays can be avoided because design, safety and siting issues will be resolved before a company starts to build a plant. Specifically, early site permit approval allows for site suitability and acceptability issues to be addressed prior to an organization`s commitment to build a plant. Responsibility for site-specific activities, including communications and public participation, rests with those organizations selected to try out early site approval. This plan has been prepared to assist those companies (referred to as sponsoring organizations) in planning their communications and public involvement programs. It provides research findings, information and recommendations to be used by organizations as a resource and starting point in developing their own plans.

Catalyst and process development for synthesis gas conversion to isobutylene. Quarterly report, April 1, 1992--June 30, 1992

Description: A rate equation for carbon monoxide consumption showing first order in CO and 0.5 order in hydrogen indicates the rate controlling step involves dissociated hydrogen. The inhibition of the rate with carbon dioxide is also shown. Examination of the hydrocarbon distributions indicates a see-saw effect with the C{sub 4}s representing the fulcrum and methane and C{sub 5}{sup +} the end points. The shift in the distributions tends to be towards the C{sub 5}{sup +} for high pressures and long residence times. This distribution can be shifted by incorporating Ti into the catalysts, but the optimum amount of Ti needs to be determined. The sol gel method of preparing the catalysts tends to produce a less active catalyst than by precipitation of a zirconyl salt. The most active catalyst contained approximately 2% Th/ZrO{sub 2}
