Title: Method for charging fuel assembly
Inventor: MATSUURA TETSUAKI
IPC: G21C5/00
Filed: 1988-12-14
Abstract: PURPOSE:To make effective utilization of channel boxes by making predictive calculation of the difference in the irradiation quantity of fast neutrons on two opposite side faces of all the channel boxes in operation and evaluating the interference of the channel boxes and control rods. CONSTITUTION:The fast neutron fluxes phi of all the fuel assemblies are calculated by using predictive calculation codes with respective cycles and the inclinations DELTAphi of the fast neutrons between the two opposite side faces of the channel boxes (CB) are determined and are multiplied by the irradiation time of the respective cycles, by which DELTAphi.t of all the CBs in the core at the end of the respective cycles are calculated. The DELTAphi.t are compared with phic.t having the possibility that the CBs interfere with the control rods and if there is the CB which attains DELTAphi.t>DELTAphic.t, such CB is exchanged with the CB in the position having such DELTAphi at which bending arises in a reverse direction. The optimum fuel charge position at which the number of the CBs to attain DELTAphi.t>DELTAphic.t are minimized is determined by repeating the above-mentioned procedures. Thus the CBs are utilized effectively.

The outputs of the detectors 21 to 30 are applied via A/D converters 31 to 40 to cumulating devices 51 to 60. The accelerometers are distant from each other and only one acts if there is impact near any thereof. The devices 51 to 60 cumulated the waveforms of all the channels while the waveforms are synchronized N times at the prescribed time before and after the generation point. The detection accuracy is enhanced to N<1/2> times in S/N by the integrated averaging of N times. An alarm is emitted from comparators 61 to 70 when the outputs of the cumulating devices exceed the levels of alarm level setters 41 to 50. A diagnosing device 71 operates an alarm device 73 when there is reasonability when compared with the delay time on the sensor channel.

Abstract: PROBLEM TO BE SOLVED: To allow some revolutions from the binding position of a binding member by slightly transferring the binding member in the open direction with the help of an urging plate when a specified engagement state under which the binding position of the binding member is regulated, is cancelled. SOLUTION: When a side plate 16 is set in an upright position and a binding member 21 is set in the binding position, the first face 17A of an urging plate 17 is positioned on the almost same face as the side plate 16 and the second face 17B of the urging plate 17 is set in an inclined position.

The binding pipe 18 has only to be rotated in the direction where the side plate 16 falls down by pinching the loose part by finger and transferring the binding pipe 18 in the arrow B direction.
