Title: Core of nuclear reactor
Inventor: KAWASHIMA KATSUYUKI
IPC: G21C7/14
Filed: 1990-07-25
Abstract: PURPOSE:To obtain large negative reactivity at a transient phenomenon by making an engaging structure of a coolant inlet part at lower end of control rod guide tube and a reactor core supporting plate, to be a short lengthened and flexible one. CONSTITUTION:A coolant inlet part 32 of control rod 3 guide tube 31 is shorter than a coolant inlet part 31, and also, in case that an amount of coolant which is engaged solely into a core supporting plate 4 in a manner of a cantilever, get reduced, and coolant temperature rising high, a fuel assembly bends itself with pushing away the control rod guide tube easily. In this way, an extent of radial expansion (deformation) of whole reactor core increases than ordinary one and there fore addable negative reactivity increases. Accordingly, in this example application, a reactor core of which countermeasure plan for coolant flow amount loss and passive safety are much emphasized, can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a quality controlling method for ready-mixed concrete by which W/C (water cement ratio) of produced ready-mixed concrete can be grasped at real time in a point of time for production. SOLUTION: The set-up weighing value of various concrete materials is set up in accordance with a compounding ratio preset on an operation panel and respective materials are weighed while keeping the set-up weighing value as a target value. When discharge of the materials into a mixer is started, actually weighed amount of cement, weighed amount of water and surface water rate of aggregate are fetched from the operation panel 1 to a quality controlling device and simultaneously the set-up weighing value is fetched. Actual result W/C (water cement ratio) is calculated at real time from the weighed amount of cement, weighed amount of water and weight of surface water stuck on the surface of aggregate. W/C error at every kneading batch, which is difference value of the actual result W/C and set-up W/C calculated similarly from the set-up weighing value, is calculated. The W/C error is plotted in a CRT indicator at every kneading batch and transition of the W/C error is indicated in a graph.

Abstract: PURPOSE:To get rid of any error in a cage position displacement detecting signal as well as to aim at the measurement of an accurate cage displacement distance by installing a mechanism, keeping off any movement due to a wind out of a reference line, in plural positions between top and bottom of this reference line. CONSTITUTION:A part of the uppermost portion of a mounting arm clamped to a guide rail 1a by a clip 11 is bent in an L-shaped form to which a reference tape 13 is being locked, and it is hung down by a weight. Each mounting arm 16 of plural pieces of section L-shaped members is anchored to the guide rail 1a at intervals by the clips 11 and bolts 12. Each bracing piece 17 is locked to each tip of these mounting arms 16 so as to come into contact with a side face of the tape 13. The bracing pieces 17 are made so as to come into contact with both sides of the tape 13 alternately. With this constitution, even if a wind being produced by cage lifting motion and air penetrating from a clearance hit on the reference tape 13, any deflection is kept back by the bracing piece 17. Consequently, a detecting signal out of a cage displacement detector comes to such a signal that is not affected by the wind, so that a cage displacement distance is accurately measurable.

Abstract: PURPOSE:To prevent the blank time in a smoke detection operation by being generated by detecting the non light emission of a light emitting lamp and alarming that the limit of the life of the light emitting lamp is close when the number of the times of the non light emission is more than the prescribed number of times. CONSTITUTION:From the time when a smoke sensor 1 is installed or a xenon lamp 10 is exchanged, the number of times when the xenon lamp 10 does not emit the light at the time to emit the light, that is, the number of the times of the non light emission is stored every month. That is, when a light emitting level by a light receiving element 20 does not arrive at a prescribed level at the time of a light emitting instruction from a control circuit 50, the number of the times of the non light emission is increased by '1.' Then, the number at every month is stored in an EEPROM 63. The total number of the times of the non light emission in the month and the figure of an alarm level, 7 times for instance, are compared by the control circuit 50 every month and a life alarm signal is outputted when the total number of the times of the non light emission in the month is more than 7. Thus, the failure of the xenon lamp 10 can be recognized beforehand and the blank period in the smoke sensing operation is not generated.
