Business
Woojin Ntec, Inc. is a South Korea-based engineering and technical services company specializing in the inspection, maintenance, testing, and integration of instrumentation and control (I&C) systems for power generation infrastructure. The company primarily operates within the nuclear and thermal energy sectors, delivering comprehensive lifecycle engineering solutions. Its core offerings and service lines include routine preventive maintenance services (continuous operational monitoring, calibration, and real-time troubleshooting of instrumentation and control loops in active power plants); planned overhaul maintenance services (comprehensive diagnostic testing, refurbishment, calibration, and replacement of critical control devices and Man-Machine Interface Systems [MMIS] during scheduled plant outages); commissioning and trial operation services (functional safety testing, system verification, and pre-commercial operational support for newly constructed nuclear and thermal power units); plant diagnosis and modernization engineering (integrity assessments, lifespan extension evaluation, and digital I&C retrofitting for aging analog infrastructure); nuclear plant decommissioning technology solutions (real-time three-dimensional radiation field mapping systems, G-CAM radiation visualization devices, and contamination assessment equipment); and proprietary component manufacturing (localization and fabrication of specialized electronic modules, sensor assemblies, signal processing units, and instrumentation control cabinets). The company primarily serves state-affiliated power utilities across South Korea, including Korea Hydro & Nuclear Power Co., Ltd. (KHNP) and the thermal power generation subsidiaries of Korea Electric Power Corporation (KEPCO), with strategic plans to expand its engineering services to overseas nuclear projects. Founded in January 2013 and headquartered in Hwaseong-si, Gyeonggi-do, South Korea, Woojin Ntec operates as a consolidated subsidiary of Woojin Co., Ltd., a specialized developer of industrial sensors and nuclear instrumentation systems. In recent developments, Woojin Ntec completed its initial public offering (IPO) and listed its common shares on the KOSDAQ market under the ticker symbol 457550 in January 2024. Concurrently, the company has undertaken major strategic business expansions into the nuclear power plant decommissioning and small modular reactor (SMR) maintenance sectors, actively advancing government-backed R&D initiatives for indigenous radiation monitoring systems, three-dimensional imaging apparatus, and next-generation reactor instrumentation control technologies.
