A nuclear power plant consists of parts over 10 million. These device have to be maintained properly for safety and high reliability. There are two types of maintenances of nuclear power plant, recovering maintenance to repair a failed device and prevention maintenance to prevent shut down. At the beginning of introduction nuclear power plant, recovering mainly had been performed only the case of occurrence of broken at nuclear power plant. As operation technology has been accumulated, they pursue safe operation by expecting failure using the cumulative data of possible device failure and performing preventive maintenance by inspection and replacement before unexpectedly shut down.
Nuclear Steam Supply System is a system to run turbines which generate electricity by converting high temperature, high pressure steam from heat occurred by nuclear fuel. There are three kinds of system as below.
Our company perform precise inspection of NCS systems by dispatching engineers during Planned Preventive Maintenance period
Development of Korean standard NSSS controller
In cooperation with KHNP, we have successfully developed NSSS controllers, before which had depended on technologies from oversea. This is a key factor of appliance on nuclear power plant, and these controllers are installed and driven properly. NSSS controller improved efficiency of products with integrated control program method of nuclear steam supply as well as contributed to the safe driving of nuclear power plant applying human engineering.
