  • Patent number: 11942228
    Abstract: More accurate prediction of reactor water quality of a nuclear reactor is implemented. A device for prediction of reactor water quality of a nuclear reactor in a nuclear power plant is disclosed. The device stores a reactor water quality prediction model which is learned using learning data, and with which future reactor water quality is predicted. An explanatory variable of the reactor water quality prediction model includes a value in a predetermined period unit that is generated from data acquired in an operating nuclear power plant. The device generates the value in a predetermined period unit from data acquired in a target operating nuclear power plant, and acquires a predicted value of the reactor water quality in the target nuclear power plant based on the reactor water quality prediction model and the value in a predetermined period unit.

  • Patent number: 11925854
    Abstract: Provided is an information processing apparatus that is to be connected to a controller apparatus including a push-button, a force sense presentation section, and the push-button. The push-button moves between a first position and a second position when depressed by a finger of a user. The force sense presentation section presents a force sense to the push-button. The information processing apparatus determines, according to a prescribed force sense setting, the aspect of a force sense to be imparted to the push-button, and controls the force sense presentation section of the controller apparatus, according to the determination. Each time a predefined operation is performed, the information processing apparatus changes the force sense setting from a current force sense setting to a different force sense setting.
