Nuclear Power Plant Control Rod Control System Software

As a contractor of Doosan Heavy Industries I&C, SINAENG Co., Ltd. has participated in obsolete equipment replacement and new construction works of multiple nuclear power plants for the localization of nuclear power plants.
The control rod control system is a system controlling the exit/insertion of the control rod for controlling the output of a nuclear power plant. It largely consists of a power control unit, a logic control unit and a supervisor management unit. We are developing the software of each part.
In particular, software of high completion level is being developed through technology development and system analysis in the power control part.
