Times Cited Count：13 Percentile：41.68(Physics, Fluids & Plasmas)The National Centralized Tokamak (NCT) facility program is a domestic research program for advanced tokamak research to succeed JT-60U incorporating Japanese university accomplishments. The mission of NCT is to establish high beta steady-state operation for DEMO and to contribute to ITER. The machine flexibility and mobility is pursued in aspect ratio and shape controllability, feedback control of resistive wall modes, wide current and pressure profile control capability for the demonstration of the high-b steady state.

Times Cited Count：15 Percentile：45.44(Physics, Fluids & Plasmas)Design studies are shown on the National Centralized Tokamak facility. The machine design is carried out to investigate the capability for the flexibility in aspect ratio and shape controllability for the demonstration of the high-beta steady state operation with nation-wide collaboration, in parallel with ITER towards DEMO. Two designs are proposed and assessed with respect to the physics requirements such as confinement, stability, current drive, divertor, and energetic particle confinement. The operation range in the aspect ratio and the plasma shape is widely enhanced in consistent with the sufficient divertor pumping. Evaluations of the plasma performance towards the determination of machine design are presented.

JNC(Japan Nuclear Cycle development institute) has been conducting the project called "Horonobe URL project" in Horonobe-cho, Hokkkaido, Japan. The aim of the project is to establish the scientific and technical basis for geological disposal on sedimentary rock. In the project, a underground facility with 500m depth will be constructed. This report is summarized the results on support design of the planned underground facility based on the data obtained by the several borehole investigations from ground surface. Owing to rational support design, the detailed compartment of the input parameters for the stability analysis in surrounding rock at position of underground facility were made based on the results of borehole investigation in HDB-1, HDB-3, which were drilled near the position. Moreover, the idea of double support system was adopted in this study to minimize the support in underground facility.
