[en] To complete the KSTAR neutral beam facility, the I and C (Instrumentation and Control) of KSTAR NBI(Neutral Beam Injector) will be also implemented. The goal of this research is to design EPICS (Experiment Physics and Industrial Control System) based I and C for KSTAR NBI, During about 10 years, KAERI has already installed and operated the neutral beam facility in the test stand, and has many operation experience and material for a new neutral beam facility. Using this experience and material, the new I and C for KSTAR NBI will be improved and implemented, and complied with KSTAR discharge scenario and operation sequence

[en] This optimization program is developed in four phases: 1) the EOC enrichment is redistributed to maximize the EOC reactivity, and a fuel loading priority scheme is developed from this; 2) the optimal regionwise BOC enrichment distribution and depletion trajectories of a 3-region core are determined by holding constant the total inventory of U²³⁵ in the core; to minimize the fuel cost, the total amount of U²³⁵ must be reduced externally; 3) by assuming that the number of fuel assemblies from each batch is fixed, the core is reloaded according to the fuel-loading priority scheme so that the averaged enrichment of each region is the same as that of the 3-region results; and 4) the depletion trajectories of individual fuel assemblies are found by forcing the region averaged burnup of each region at each depletion step to follow the optimal trajectories of the three regions. A preliminary study of the optimizing of cycles one and two of the TMI-1 reactor is presented. It allows more flexible poison control to show the general trend of the optimization. The optimal depletion trajectories require a low leakage core throughout the cycle. More stringent control poison constraints can be exercised in the future using these methods

[en] Some gauge theoretical models of CP violation are discussed. The Kobayashi-Mashawa model of CP violation is reviewed, followed by a critical analysis of Weinberg's model of spontaneous CP violation in SU(2) x U(1) gauge theory. The left-right symmetric SU(2) x SU(2) x U(1) models of electroweak interactions are then discussed, focussing on the isoconjugate model of CP violation. Finally, a model for spontaneous CP violation in SU(2) x SU(2) x U(1) is presented. Unlike SU(2) x U(1) models, CP violation arises here naturally out of a minimal Higgs sector. Some phenomenology of CP violating processes have also been discussed

[en] For the past four years, Occidental Research Corporation has been conducting a fusion program which is based on a reactor concept in which geometrically focused and time compressed beams of cold light ions and neutralizing cold electrons from large area sources are ballistically propagated over several meters through a near vacuum to implode a pellet target. The approach combines the cost advantage of efficient moderate voltage pulsed power technology with the simplicity-advantage of unguided ballistic propagation. In addition, the compactness, efficiency, focusability and energy range of the system makes the approach of great interest for supplementary heating of magnetically confined fusion plasmas. Theoretical analyses have been made of beam-target interaction, beam progagation and source accelerator design. A one-dimensional implosion and nuclear burn code indicates that significant yields can be obtained from simple targets with moderately energetic light ions. Experimentally the short-term objective is to demonstrate that the required degree of space-time focusing can be achieved on a 200-500 keV electron neutralized ion (or plasma) beam from a simple prototype 100 sq cm low temperature zeolite source

[en] The FEMP Baseline establishes the basis for integrating environmental activity technical requirements with their cost and schedule elements. The result is a path forward to successfully achieving the FERMCO mission. Specific to cost management, the FEMP Baseline has been incorporate into the FERMCO Project Control System (PCS) to provide a time-phased budget plan against which contractor performance is measured with an earned value management system. The result is the Performance Measurement Baseline (PMB), an important tool for keeping cost under control

[en] The box diagrams contributing to the CP-odd part m' of the kaon mass matrix in the Weinberg model of CP violation are evaluated with careful inclusion of external momenta. The contribution from diagrams with exchange of two Higgs bosons are found to be significant although generally somewhat smaller than those involving one Higgs and one W boson. A phenomenological analysis of CP-violating kaon decay is carried out, using as parameters the Higgs mixing angles, the CP-violating decay amplitude (presumably due to Higg's-boson penguin diagrams), and the corresponding dispersive contribution to m'

[en] We propose and analyze a minimal model of spontaneous CP violation with the gauge symmetry SU(2)sub(L) x SU(2)sub(R) x U(1)sub(B-L). We find that the 'isoconjugate relation' of Mohapatra and Pati is no longer valid in this model even for the four-quark case. However, due to a dynamical effect, all three of the main superweak predictions (etasub(+-)=eta⁰⁰, etasub(+-0)=eta⁰⁰⁰ and etasub(+-0)=etasub(+-)) are approximately true to better than 1%. For the six-quark-case, we find the Kobayashi-Maskawa phase is calculable and small so that its presence does not appreciably change the phenomenology of the model. (orig.)

[en] Accurate measurements of neutron doses in the containment of a commercial nuclear power plant have been a concern in the last several years. If neutron dosimeters are used to assess exposures in a spectral environment substantially different from that in which they were calibrated, the dose equivalent interpretation of these dosimeters can be an order of magnitude higher than the actual dose. Proper characterization of the spectral environment will provide proper corrections for the reading. Many computer programs have been written for unfolding the spectrum with the measured count rates. A new unfolding computer code has been devised based on the response function calculated from a neutron transport code for 25 neutron energy groups from thermal to 15 MeV
