In 1979, a K-edge densitometer (KED) was installed by the Safeguards Assay group from Los Alamos National Laboratory in the PNC reprocessing plant at Tokai-mura, Japan. It uses an active nondestructive assay technique, KED, to measure the plutonium concentration of the product solution. The measurement uncertainty of an assay depends on the count time chosen, but can be 0.5% or better. The computer hardware and software were upgraded in 1992. This manual describes the operation of the instrument, with an emphasis on the user interface to the software.

The mechanical behavior of a silicon crystal under bending is investigated. For a crystal of length 30 mm and thickness 3 mm, to achieve the specified bend angle of 0.64 mrad, the appropriate angle of the aluminum punches is 0.96 mrad.

Hybrid technologies for the reduction of NO{sub x} emissions from coal-fired utility boilers have shown the potential to offer greater levels of NO{sub x} control than the sum of the individual technologies, leading to more cost effective emissions control strategies. Energy and Environmental Research Corporation (EER) has developed a hybrid NO{sub x} control strategy involving two proprietary concepts which has the potential to meet the US Department of Energy`s NO{sub x} reduction goal at a significant reduction in cost compared to existing technology. The process has been named CombiNO{sub x}. CombiNO{sub x} is an integration of three technologies: modified reburning, promoted selective noncatalytic reduction (SNCR) and methanol injection. These technologies are combined to achieve high levels of NO{sub x} emission reduction from coal-fired power plants equipped with S0{sub x} scrubbers. The first two steps, modified reburning and promoted SNCR are linked. It has been shown that performance of the SNCR agent is dependent upon local oxidation of CO. Reburning is used to generate the optimum amount of CO to promote the SNCR agent. Approximately 10 percent reburning is required, this represents half of that required for conventional reburning. If the reburn fuel is natural gas, the combination of reburning and …

Often inert material exists in front of a calorimeter. If an electromagnetic (EM) shower initiates in this material, and energy is not sampled by the calorimeter, then energy resolution will be degraded. It is crucial to minimize the amount of inert material. Algorithms using a separate readout of the energy early in the shower (a ``preshower`` detector) can also be used to alleviate the reduced performance. This problem has previously been studied using CDF test beam data. In addition, an EGS simulation was used to look at the methods of using the preshower (PS) readout to reduce the energy error.
