Title: Fuel assembly for nuclear reactor
Inventor: DOUMOTO NOBORU
IPC: G21C3/344
Filed: 1990-05-23
Abstract: PURPOSE:To improve fuel utilization efficiency by enabling shifting a void reactivity coefficient of coolant during plant operation, to negative side without lessening intervals (grid pitch) between fuel assemblies. CONSTITUTION:To a spacer supporting tube 3 placed at a central part of a fuel assembly, a plurality of void flowing in and out holes 11, other than light water flowing in and out holes 8 and 9, are provided within a void generating region of effective fuel part, and therewith light water in a fuel part and light water in the spacer supporting tube, mix together through those holes and also enable generating void in the spacer supporting tube 3 in the same manner as the light water in the fuel part. In this case, even if the void ratio rises high, output of fuel rods at inner layers scarcely increases. Consequently, reactivity coefficient of coolant void shows a negative value compared to that in an ordinary fuel assembly. Therefore, the grid pitch can be increased as much as the reactivity coefficient is shifted to a negative side. By this procedure, burn-up of the fuel assembly can be improved.

Inventor: YUHARA KOUHEI
IPC: H01F38/08
Filed: 1982-07-28
Abstract: PURPOSE:To reduce eddy-current loss of a transformer wherein a core comprises at least two main cores forming the main magnetic path and path cores forming the leakage magnetic path. CONSTITUTION:When high frequency voltage is applied to a primary coil 10, the alternating magnetic flux of high frequency passes a ferrite core 1 and voltage is induced in a secondary coil 11 in accordance with main magnetic flux phi1 crossing with the secondary coil 11 out of the passing magnetic flux as well as the winding ratio between primary and secondary coils. Leakage magnetic flux phi2 out of both leakage fluxes phi2 and phi3 passes through path cores 1-3, 1-3. In other words, the leakge magnetic flux distributed near the abutted portion of main cores 1-1, 1-2 in the absence of the path cores 1-3, 1-3 can be concentrically passed through the path cores 1-3, 1-3. Thus, it becomes possible to greatly reduce the leakage magnetc flux crossing with both primary and secondary coils 10, 11 and hence to significantly reduce eddy-current loss due to the leakage magnetic flux.

Filed: 1989-05-25
Abstract: PURPOSE:To obtain the angular signal stable over wide rotating speeds by providing a means for making time analysis of the output obtd. from the windings of a pulse motor. CONSTITUTION:The voltage VL generated in the winding A1 or B1 when the pulse motor 1 is used as a generator is VL=n(dphi/dt), where (n) is the number of turns of the winding, dphi/dt is the time differentiation of the magnetic flux crossing the winding. The approximate integration action to the change faster than time constant of CR of a resistor R and a capacitor C is made and the output voltage V is made into V=nphi/CR when the voltage is inputted to integrating circuits 2, 3. Namely, the output voltage when there is no error voltage is nphi/CR, the max. value and min. value thereof is + or -(nphimax/CR). The nphimax/CR is equaled to the forward voltage of diodes by connecting parallel circuits 4, 5 of the diodes in parallel with an integrating capacitor. The output voltages of the circuits 2, 3 when the rotation is started from the static state are transferred to a stationary rotating state in a short period of time in this way.

Abstract: PROBLEM TO BE SOLVED: To prevent improper partial fusion of a fuse by connecting a plurality of fuses, which are arranged on one and the same plane including a center line of a reactor, in parallel by a supporting conductor and connecting the supporting conductor and the reactor in series. SOLUTION: Respective fuses 2a-2n are arranged on one and the same plane including the center line 0 of a reactor 4 and respective fuses are arranged in parallel by a supporting conductor 3 and further the conductor 3 and the reactor 4 are connected in series. In this case, since the conductor 3 is so constituted as to connect respective fuses in parallel on one and the same plane including the center line 0 of the reactor 4, the magnetic fluxes 5 do not cross the direction (X-axis direction) in which induction electromotive force is generated in the conductor 3 or in respective fuses. Consequently, no induction current flows in respective fuses and load current flowing in the reactor 4 is divided uniformly to respective fuses.  As a result, no temperature difference is caused in respective fuses, so that large current flow in a specified fuse and improper fusion of a specified fuse are prevented.
