摘要： To eliminate or reduce stress for an operator who operates an operation panel. A touch panel-type operation panel includes a display with touch panel including an image display surface for displaying an operation part and a control device. The display with touch panel detects approach of an operation finger to the operation part and the position of the operation part and outputs signals of the detected approach of the operation finger and the detected position. The control device predicts and analyzes, in response to an input of the signals of the approach of the operation finger and the position, a state of a control target by operation corresponding to the operation part with reference to state data of the control target, determines appropriateness of the predicted and analyzed operation, and outputs a result of the determination.

摘要： In a fuel assembly, a plurality of fuel rods are arranged in an array of 10 rows and 10 columns in the cross section of the fuel assembly. A flow resistance member is disposed in a central portion in the cross section at upper end portions of partial length fuel rods which are a part of the fuel rods. In the flow resistance member, resistance members are each disposed between ferrules arranged in an array of 6 rows and 6 columns in the diagonal direction of the flow resistance member. Resistance members are each disposed between the ferrules in a peripheral portion of the flow resistance member. By disposing the resistance members, the pressure loss in an inner region in the cross section of the fuel assembly is increased, and the flow rate of a gas-liquid two-phase flow in an outer region surrounding the inner region is increased.
