Comprehensive plans are in place to enhance nuclear power plant operation to achieve higher performance, including longer fuel cycle operation and uprating the reactor's rated thermal power output. Similarly, many plants have been upgraded by replacing component and/or equipment that have obsoleted. In an environment in which new operating phases coexist with both new replaced equipment and existent equipment, it is necessary to have an instrumentation and control system capable of monitoring and properly controlling a wide range of state conditions from the equipment level to the plant level in order to obtain maximum performance from the plant while ensuring that its operating state remains stable and highly reliable. By constantly employing the state-of-the-art digital technologies, Hitachi has developed instrumentation and control technologies for achieving highly efficient and reliable nuclear power plants.
