As part of the spent fuel treatment program at the Idaho National Laboratory, a vacuum distillation process is being employed for the recovery of actinide products following an electrorefining process. Separation of the actinide products from a molten salt electrolyte and cadmium is achieved by a batch operation called cathode processing. A cathode processor has been designed and developed to efficiently remove the process chemicals and consolidate the actinide products for further processing. This paper describes the fundamentals of cathode processing, the evolution of the equipment design, the operation and efficiency of the equipment, and recent developments at the cathode processor. In addition, challenges encountered during the processing of irradiated spent nuclear fuel in the cathode processor will be discussed.

In this study, a double-solvent radiation method is proposed to prepare silver nanoparticles in the pores of metal-organic framework MIL-101(Cr). The results reveal that well-dispersed silver nanoparticles with a diameter of about 2 nm were successfully fabricated in the cages of monodisperse octahedral MIL-101(Cr) with a particle size of about 400 nm. The structure of MIL-101(Cr) was not destroyed during the chemical treatment and irradiation. The resulting Ag/MIL-101 exhibits excellent catalytic performance for the reduction of 4-nitrophenol. This method can be extended to prepare other single or bimetallic components inside porous materials.

Purpose: The purpose of this study is to provide basic information for the establishment of a Heavy Ion Therapy center by analyzing the cases of Heavy Ion Therapy devices, introducing the equipment and space composition of Heavy Ion Therapy equipments. Methods: This study is carried out by study the Heavy Ion Therapy, by figure out status of the installation of treatment centers around the world and by analyze the composition of Heavy Ion Therapy equipments and spaces through case studies. Results: The results of this study, which investigated the treatment of Heavy Ion Therapy and analyzed the plans of the five Heavy Ion Therapy centers, are summarized as follows. 1) Heavy Ion equipment requires a significant floor area. Vertical as well, many cross-sectional areas need to be secured for the construction of a delivery system. The Heavy Ion Therapy device should be built as a shielded wall because of the radiation leaking. Therefore, it is necessary to consist of a independent treatment center. 2) The size of Heavy Ion devices is getting smaller. Linac can be put into syncrotron. and the size of syncrotron, delivery system, and rotating-gantry is getting smaller. 3) Japan is often installed for treatment, and control rooms are integrated, while Europe has secured research space and each control room is separated. Implications: People are not familiar with the Heavy Ion Therapy. And the effectiveness of the treatment is not well promoted yet. Hopefully, more attention will be paid to the research involved in the Heavy Ion Therapy.

If remodeling is defined as activities that restore the overall function of a building up to the standards currently demanded rather than as a simple replacement or repair of old facilities and equipment, the main task of remodeling should be the reduction in differences between areas, establishment of a functional linkage between departments and setup of a smooth circulation system. Therefore, this study is an analysis of remodeling strategies and construction processes to resolve major tasks of remodeling. Through this research we acquire concluding remarks. 1) The remodeling strategies of equipment-intensive areas can be divided into two measures: utilizing the existing buildings (the main buildings) the most, and of concentrated relocation in the new buildings. The former method is advantageous in that the main building serves as a center in hospital layouts because concentrated placement of the diagnosis/ treatment area and the supply area benefit the overall operation in terms of functions. However, the measure has limits in that it is difficult to install the facilities and equipment of the new demands due to the low ceilings, which serve as a potential challenge in future growth and changes. 2) The latter measure is the one in which equipment-intensive areas and the areas that are absolutely short of space are first placed in the new buildings while other areas (the outpatient area, the administration area and the miscellaneous areas) are in the existing building (main building). Given the possibility of development In the future, concentrated placement in the new buildings can be said to be more effective order to actively address future growth and changes.
