摘要： PURPOSE:To display sufficient information about the movement of a control rod by making prescribed calculations based on the output information in the upper half and lower half regions of a core. CONSTITUTION:The Xe concentration and I concentration in the upper half and lower half regions of a core are calculated based on the outputs PT, PB in the upper half and lower half regions of the core. The Xe (I) concentration calculated momentarily appears as the concentration in the equilibrium state. The outputs PTX, PBX (PTI, PBI) in the upper half and lower half regions of the core are obtained based on the Xe (I) concentration. The deviations AOX, AOI of the corresponding axial output distribution to be realized as the equilibrium state with the present transient Xe concentration and I concentration, the axial output distribution deviation AOP of the core at the time, and parameters DAOIX, DAOPX defined by these deviations are calculated by the equations from the outputs. The locus is displayed with DAOIX used as the Y axis and DAOPX as the X axis, and Xe oscillation is controlled based on the locus information, i.e., a control rod is operated with the locus used as the origin.

摘要： PURPOSE:To provide a blanket for fusion reactor in which overcooling problem of tritium breeder due to cooling water channel on the side wall of blanket container is solved. CONSTITUTION:Overcooling problem is solved by placing a thermal insulating member 8, i.e., a woven fabric of stainless steel wires as thin as 50mum or less, between a can 5 filled with tritium breeder 2 and the side walls 1a, 1b of blanket. Thermal insulation effect equivalent to that of conventional ceramic thermal insulation member can be achieved. Furthermore, tritium adsorption problem by the thermal insulation member can also be solved using quite thin stainless steel wires while enhancing workability.

摘要： PURPOSE:To realize the reduction in a cost by the improvement of the reliability of a through-part design and the efficiency of a working without depending on a human processing. CONSTITUTION:A through design face is inputted from an automatic through- part design face input part 2 according to a design working range based on the shape of the wall or floor of a building structure from a data input part 1 and a through-part position is automatically extracted by an automatic through-part position extraction processing part 3 from the inputted through-part design face and route information. Then, a through-part shape and attribute is automatically selected by an automatic through-part shape and attribute setting processing part 4 from the extracted through-part position, shape and attribute of the wall or floor of the building structure, route shape and attribute, and design condition.

摘要： PURPOSE:To obtain a non contact type surface pollution density inspector which has a detection part adapted to measure a pollution density accurately and a signal processing part in a high radiation environment field. CONSTITUTION:gamma-rays 11 and beta-rays 12 emitted from a surface pollutant 10 are incident on radiation detecting sections 1 and 2 to generate electric pulses. The electric signals are amplified with amplifiers 4 and 5. noise components are removed with discriminators 6 and 7 and then, the electric signal alone attributed to the beta-rays 12 is extracted with an anti-coincidence circuit 8. The results are inputted to display a radiation unit a display section 13.

摘要： PURPOSE:To surely suppress the core reactivity of a fast breeder reactor. CONSTITUTION:A pin 15 of an extension link mechanism 10 joints with a cum groove 14 provided on a cum unit 9 and the cam unit 9 is moved up and down by the thermal expansion difference between a temperature sensing cylinder 7 and a low thermal expansion rod 8, and thus the length of the extension link mechanism 10 is varied. A thermal resister 16 made of such steel as Inconel 625 and the like having small heat conductance is placed in the inner periphery of the temperature sensing cylinder 7, which delays the heat conduction to the cum unit support rod 8 at this moment. During a slow coolant temperature rise like in normal startup, the temperatures are the same between the temperature sensing cylinder 7 and the cum unit support rod 8 and thermal expansion difference does not occur. During a rapid coolant temperature rise, the heat conduction to the cum unit support rod 8 is delayed by the heat resister 16 and thus, temperature difference is caused between the temperature sensing cylinder 7 and the cum unit support rod 8, which extends the extension link mechanism 10. The shape of the cum groove 14 is set so that the extension mechanism 10 does not extends until the normal operation temperature and it extends beyond the normal operation temperature.

摘要： PURPOSE:To improve the integrity of heat structure by mixing metal with ceramic and composing an armor block part by means of a mixed material obtained by continuously changing its composition ratio. CONSTITUTION:An armor tile block 7 is composed of a part 4 of 100% copper, a mixed material part 5 obtained by mixing ceramic such as with tin copper and an armor tile 2 composed of carbon material such as C/C composite material, and a hole for putting through a metal-made cooling tube 1 is provided in the part 4. Compositional ratio of the part 5 indicates that copper is high in the side near the part 4 and ceramic such as tin is continuously heightened as it approches to the tile 2. And the adhesion between materials is heightened through an active metal-thin inserted material 6 such as TiC in the boundary part between the tile 2 and the part 5. Next, the cooling tube 1 is put through the hole of the part 4 and a contact face is vacuum-brazed and fixed for connection. Thereby keeping of residual stress and thermal stress is suppressed and the thermal structural integrity of the material is heightened.
