Title: Emergency stop operation of nuclear reactor
Inventor: EGUCHI YUMIKO
IPC: G21C7/08
Filed: 1990-07-21
Abstract: PURPOSE:To stop a nuclear reactor within a short time in case of emergency by inserting control rods present at the position high in reactivity of the nuclear reactor at higher speed. CONSTITUTION:The core of a nuclear reactor is constituted by arranging a large number of unit lattices 4, wherein four fuel assemblies 3 are arranged to the periphery of control rods 2 arranged crosswise, in a lattice form. The peripheral part of the core is low in output as compared with the center part thereof and narrow in a range receiving the effect of the control rods. The control rod worth other than the peripheral part becomes high toward the center of the core. Therefore, at the time of the scram of the nuclear reactor, the control rods of the center part of the core effective for the lowering of output at the positions where X-marks are applied are inserted at speed higher than that of the other control rods by driving a high speed scram mechanism. Since the output of the lower part of the core is low, the boron content of the lower parts of the control rods is reduced to reduce the wt. of the control rods. By this method, the nuclear reactor can be stopped within a shorter time.

Filed: 1994-08-18
Abstract: PURPOSE: To prevent any clearance from being generated between first and second yokes even though temperature loads are applied to the yokes, by securing a gap between the first and second yoke for a molding resin to flow therein. CONSTITUTION: Between first and second yokes 15, 16, a gap for a molding resin to flow therein is secured. That is, such a molding structure is adopted that when a mold shell 17 is molded, the molding resin flows not only in gaps d1, d2 present among magnetic pole teeth 11a, 15a, 12a, 16a and bobbin wiring space parts e, f present in external yokes 11, 12, but also in a gap g present between the internal yokes 15, 16. Thereby, even though the temperature loads of a refrigerant, etc., are applied to the internal yokes 15, 16, the clearances caused by thermal deformations are not generated in the internal yokes 15, 16 and cracks are not generated in the mold shell 17. As a result, a mold coil having a waterproof structure wherein the problems of insulation faultinesses are resolved can be obtained.
