F-Canyon continues to obtain good chloride removal from Rocky Flats Alloy solution during head end treatment. One single batch of solution from the thirteenth alloy campaign, dissolved earlier this month, has been successfully processed. This was the first campaign to combine Rocky Flats Scrub Alloy (RFSA) with Rocky Flats Anode Heel Alloy (RFAHA) in the same dissolution solution (TA-2-1183). Following dissolution in Tank 6.4D, chloride was precipitated with mercurous ion added as the nitrate. The precipitate, Hg{sub 2}Cl{sub 2}, was concurrently removed with the gelatin floc via centrifugation. For this batch, a set of duplicate samples was initially obtained from Tank 11.2. However, due to repeated acid and density measurements by Laboratories, the volume of sample remaining was insufficient to permit chloride analysis. Samples of the same solution, now transferred to Tank 13.3, were analyzed. During the transfer, a 2% dilution occurred, but this error is not significant due to the larger error in the chloride analysis. For the single batch of RFSA-RFAHA material processed from the thirteenth campaign, the head end product contained 52 ppm ({micro}g/mL) chloride, a DF of 22. Relative standard deviation of the measurement was {+-}6 ppm (n = 4) for a precision of {+-}12%.

Objective was to develop a glass utilizing the silica waste material from geothermal energy production, and to supply local artists with this glass to make artistic objects. A glass composed of 93% indigenous Hawaiian materials was developed; 24 artists made 110 objects from this glass. A market was found for art objects made from this material.

UCO kernel fabrication was previously demonstrated at 2 kg per batch. The limiting factors were the size of the sintering furnace and the UCO drop columns. The former UCO drop columns also showed considerable variability in the quality of gelled microspheres. A larger-size sintering furnace and a set of drop columns with an improved design were installed in 1987. The new set of drop columns and sintering furnace, in conjunction with other modular-sized equipment, were designed to produce the reference batch size of 5.5 kg of UCO kernels containing 5 kg of heavy metal (HM). The new equipment was utilized in the manufacture of several 2 kg batches of UCO kernels and ran well. In the process development reported here, the batch size was scaled-up to 5.5 kg. While the equipment is performing as expected, some of the process parameters still need to be optimized. In the body of this document is a description of the process to make UCO kernels via Gel Supported Precipitation (GSP) technology and the critical parameters that were changed to scale-up the kernel batch size to 5.5 kg, while meeting product specifications.

FEL3D is a three dimensional simulation code, written for the purpose of calculating the parameters of coherent radiation emitted by electrons in an undulator. The program was written predominantly for simulating the coherent super-radiant harmonic frequency emission of electrons which are being bunched by an external laser beam while propagating in an undulator magnet. This super-radiant emission is to be studied in the TOK (transverse optical klystron) experiment, which is under construction in the NSLS department at Brookhaven National Laboratory. The program can also calculate the stimulated emission radiometric properties of a free electron laser (FEL) taking into account three dimensional effects. While this application is presently limited to the small gain operation regime of FEL's, extension to the high gain regime is expected to be relatively easy. The code is based on a semi-analytical concept. Instead of a full numerical solution of the Maxwell-Lorentz equations, the trajectories of the electron in the wiggler field are calculated analytically, and the radiation fields are expanded in terms of free space eigen-modes. This approach permits efficient computation, with a computation time of about 0.1 sec/electron on the BNL IBM 3090. The code reflects the important three dimensional features of the electron beam, …

In the interaction region of the SLC, the information of beam position monitors (BPM) is used to get crucial information on the beam parameters, like the position, the inclination, or the deflection of the beams at the interaction point. The information is usually extracted from the BPM readings by fitting orbits, using the known twiss parameters at the BPM positions. The quality of these fits depends, however, on the assumed resolutions of the BPMs. This is a particularly serious problem in the interaction region, since BPMs with quite different resolutions and very different values for the beta-function have to be combined. This note presents a method which allows empirical extraction of BPM-resolutions from the orbit-fits. The method has been originally developed in reference. It has been tested by Monte Carlo simulations and successfully exploited for the measurement of spatial resolutions of a time projection chamber. 2 refs., 3 figs., 5 tabs.

The goal of this research is to develop catalysts that directly convert methane and light hydrocarbons to intermediates that later can be converted to either liquid fuels or value-added chemicals, as economics dictate. During this reporting period, we synthesized several phthalocyanine catalysts supported on magnesia (MgO) in Task 3. In Task 4 we have tested these catalysts for oxidation of methane and did a number of blank experiments to determine the cause of the low methanol yield we have observed. Magnesia supported catalysts were prepared by first synthesizing the various metal tetrasulfophthalocyanines (TSPCs), converting them to the acid form, and then supporting these complexes on a basic support (MgO) by a neutralization reaction. The metals used were Ru, Pd, Cu, Fe, Co, Mn, and Mo. CoTSPC was also synthesized in zeolite Y using our standard template techniques described in Quarterly Report No. 1. These complexes were examined for catalytic activity in the oxidation of methane. The PdTSPC/MgO had greater activity, and oxidized some of the methane (selectivity of 2.8% from the methane oxidized at 375{degrees}C) to ethane. This is a much lower temperature for this reaction than previously reported in the literature. We also examined the reactivity of various components …

This paper discusses the use of fluorescent screens for the measurement of beam profiles on non-circulating particle beams. An expression for the intensity of the beam profile as a function of phosphor thickness is given. 3 refs., 8 figs.

The Effluent Treatment Facility (ETF) criticality review identifies two potential scenarios for criticality: (1) An instantaneous release of a significant quantity of fissile material from a process upset; and (2) A gradual accumulation of fissile material in process vessels. The potential for an instantaneous release from 211-H will be eliminated by the installation of a nuclear safety blank as recommended in the criticality review. With the nuclear safety blank installed, the only mechanism for introducing a gradual accumulation of uranium to the ETF from 211-H will be via Acid Recovery Unit (ARU) and General Purpose (GP) evaporator overheads. This study has determined that the maximum credible annual release of uranium-235 to the ETF from these sources is 106 grams.

There is some concern that the FB-Line D1 dissolver may have been pressurized above the liquid head pressure by a reaction that occurred in the dissolver. The D1 Pu limit of 8.8 kg is based on a tank with an inner slab thickness of 3.34 inches and a wall thickness of 0.40 inches for a total slab thickness of 4.14 inches. When the incident occurred there was less than 1,500 gm Pu (1,323 gm) in the dissolver. Some calculations were made to determine the safe slab thickness for 1,500 gm Pu in the D1 dissolver. Calculations show that 1,500 gm Pu can be safely contained in a 6 inch thick D1 dissolver provided the cabinet panels are in place.
