Advanced development of a pressurized ash agglomerating fluidized-bed coal gasification system. Quarterly progress report, April 1-June 30, 1982
The overall objective of the Westinghouse coal gasification program is to demonstrate the viability of the Westinghouse pressurized, fluidized bed, gasification system for the production of medium-Btu fuel gas for syngas, electrical power generation, chemical feedstocks, or industrial fuels and to obtain performance and scaleup data for the process and hardware. Progress reports are presented for the following tasks: (1) operation and maintenance of the process development unit (PDU); (2) process analysis; (3) cold flow scaleup facility; (4) process and component engineering and design; and (5) laboratory support studies. Some of the highlights for this period are: TP-032-1, a single stage, oxygen-steam blown gasifier test was conducted in three operational phases from March 30, 1982 through May 2, 1982; TP-032-2 was conducted in two operational phases from May 20, 1982 through May 27, 1982; TP-032-1 and TP-032-2 successfully served as shakedown and demonstrations of the full cyclone cold wall; no visible deposits were found on the cold wall after processing highly fouling coals; samples of product gas produced during TP-032-1, were passed through four different scrubbing solutions and analyzed for 78 EPA primary organic pollutants, all of which were found to be below detection limits; TP-M004, a CO/sub 2/ tracer …

Single-column-based absorption process for treating dissolver off-gas
The fluorocarbon absorption process for krypton and xenon removal from dissolver off-gas is based on exploitation of solubility differences which exist among noble gases and other gas-phase constituents in the fluorocarbon solvent dichlorofluoromethane (refrigerant-12). Process performance and reliability have been demonstrated on an engineering scale with over 10 years of pilot plant operation, including testing with /sup 85/Kr, /sup 133/Xe, and /sup 131/I. The culmination of this work is a single-column design which results in a simplified process with improved reliability and lower cost. Data are presented summarizing recent single-column development activities. These include data plots depicting decontamination factor vs feed gas flow rate, DF vs process absorption factor (kG/L), and location of the concentration peak via the solvent flow rate. In general, 99% removal is easily obtainable for Kr, Xe, and CO/sub 2/ while attaining concentration factors on the order of 10/sup 3/ to 10/sup 4/. Further concentration of the Kr product is investigated using solid sorbent and cold trapping technologies. Effective removal of entrained fluorocarbon solvent and CO/sub 2/ from the single-column product stream is demonstrated using 13X and 5A molecular sieves, respectively. Additional separation of Xe is studied using a silver mordenite bed and compared to existing …

CASIM predictions of Meson West Tevatron target soil activation
A new Meson West Target has been proposed for Tevatron II. The dump design proposed by David Eartly is shown. A longitudinal side view of the dump and the shield for target produced muons is shown. The core of the dump is seen to be a copper plate surrounding the beam. The copper is surrounded by iron, which is in turn shielded by concrete. The tunnel is embedded in sand and gravel. The sand and gravel within 3' of the concrete is continuously drained by underdrains. Soil below the top of the underdrains is not considered to be protected. Activity produced in the unprotected soil below can be leached out, transported to the aquifer, and subsequently reach public water supplies. It is the activation of this unprotected soil which is of particular interest. Since the specific type of beryllium target to be used has not yet been decided, and since it would only reduce the resultant soil activation, I have chosen to ignore it and to presume that all the targetted intensity is lost on the dump. I have made CASIM calculations of the levels of soil activation to be expected using the proposed dump design. Since the activation of …

Investigations on SYNROC mineralogy. Progress report
Progress reports are presented for the following projects: (1) factors influencing the leaching performance of hollandiate; (2) incorporation of uranium and rare earths into zirconolite; (3) reconnaissance studies of the stability relations of Ca-Ti-Al phases in SYNROC C formulations; (4) immobilization of highly aluminous sludges; (5) SYNROC D formulations produced by sintering in air; (6) crystallization behavior of interstitial glass in SYNROC D formulations. Some of the highlights are: (1) leaching performance of all hollandites irrespective of preparation technique, can be improved by hot-pressing under specific controlled redox conditions, below Ni-NiO; (2) there is no satisfactory crystal-chemical reason why the leaching performance of Ti/sup 3 +/-bearing hollandite should be superior to that of Al/sup 3 +/ hollandite; (3) experiments have shown that the zirconolite lattice can accept up to 30% rare earths (Sm/sub 2/O/sub 3/) before becoming destabilized in favor of pyrochlore or a related f.c.c. structure; (4) SYNROC zirconolites will therefore be well below their saturation limits in rare earths and trivalent actinides; (5) experiments have established that the Ca-Ti-Al phase (CTA) is compatible with perovskite, hollandite and zirconolite; (6) magnetoplumbite-type phases coexists with hollandite, perovskite, zirconolite and Fe-bearing pseudobrookite, but do not coexist with the CTA phase CaTi/sub …

Physics basis for an axicell design for the end plugs of MFTF-B
The primary motivation for conversion of MFTF-B to an axicell configuration lies in its engineering promise as a reactor geometry based on circular high-magnetic-field coils. In comparing this configuration to the previous A-cell geometry, we find a number of differences that might significantly affect the physics performance. The purpose of the present document is to examine those features and to assess their impact on the performance of the axicell, as compared to the A-cell configuration, for MFTF-B. In so doing, we address only those issues thought to be affected by the change in geometry and refer to the original report Physics Basis for MFTF-B, for discussion of those issues thought not to be affected. In Sec. 1, we summarize these physics issues. In Sec. 2, we describe operating scenarios in the new configuration. In the Appendices, we discuss those physics issues that require more detailed treatment.
