Systems and methods provide data gathering and execution on the same without human operations. Systems may include controls and sensors that electronically provide data and operations to a processor networked with the same. For a nuclear reactor, the processor may determine reactivity from the sensors and issue commands to actuators to operate the reactor. Reactivity may be determined based on all reactivity factors determined from the plant data, including the use of modelling. The processor may position control elements or moderator feeds to achieve a desired reactivity. The processor may be networked to plant switches and sensors, and multiple processors may be used to independently calculate and decide on plant operations. Human operator input is not required at discreet instances of plant operational change; systems may include displays and input interfaces to permit observation and/or intervention if absolutely necessary.

The invention relates to a device for controlling a plurality of nuclear reactors, comprising, for each nuclear reactor, a plurality of sensors for measuring operating parameters as well a system for controlling the nuclear reactor.

A component interface module with enhanced user convenience, according to the present invention, is a component interface module for managing the interface between a control system, which generates component command signals, and components, which generates component feedback signals, wherein the components are classified into first to third component groups, the component interface module is formed from first to third component interface modules, each of the first to third component interface modules includes: an input port; a processor including a priority logic, a component logic and a diagnostic logic; and an output device, the priority logic is set using a four-contact rotary switch for selecting any one of four settings in order to set the priority for the component command signals, and the component logic is set using a control rotary switch of each of the first to third component interface modules.

The systems and methods generally include a nuclear power plant unit assembled in a shipyard from a plurality of structural modules, each of the structural modules having manufactured components for use in power production when moored or fixed to a floor at least one of in and proximal to at least one of an offshore marine environment, a river environment and a coastal marine environment. The nuclear power plant unit is subdivided into at least one arrangement of structural modules that includes an electrical interface for one of transmitting electrical power generated by the nuclear unit and powering a system of the unit, a communications interface for communications internal or external to the unit, a user interface that is configured to permit a user to access a system of the unit, and a network interface for data communications to or from the unit.

A nuclear reactor protection system includes a plurality of functionally independent modules, each of the modules configured to receive a plurality of inputs from a nuclear reactor safety system, and logically determine a safety action based at least in part on the plurality of inputs, each of the functionally independent modules comprising a digital module or a combination digital and analog module, an analog module electrically coupled to one or more of the functionally independent modules, and one or more nuclear reactor safety actuators communicably coupled to the plurality of functionally independent modules to receive the safety action determination based at least in part on the plurality of inputs.
