Wooree Technology Signs 8.5 Billion Won Nuclear Power Plant Control System Supply Contract

Wooree Technology has signed an 8.5 billion won supply contract with Korea Hydro & Nuclear Power for the Data Acquisition System (DAS) for the main computer (PMS) of Kori Units 3 and 4.

According to Wooree Technology on August 20, the deal accounts for 9.7% of the company’s sales from the previous year, with a contract period extending until February 2028. Wooree Technology will supply the DAS used in nuclear power plant monitoring systems, as well as provide system construction and technical support. Through this project, the company aims to upgrade the nuclear control and instrumentation systems, ensuring precision monitoring of major facilities at Kori Units 3 and 4 and enabling stable collection and management of operational data.

Ensuring the stable operation of nuclear power plant facilities requires highly reliable data collection and an integrated monitoring system. The PMS monitors and analyzes the operational status of the main systems and facilities of the plant in real-time, while the DAS collects and stores measurement and operational data within the plant, supporting the identification of abnormal signs and decision-making for maintenance. In particular, since DAS is directly linked to the operational reliability of nuclear control and instrumentation systems, it is a field that demands high technical reliability and extensive implementation experience.

Wooree Technology continues to expand its performance in securing contracts, leveraging its position as the sole domestic supplier of nuclear MMIS DCS. In the first quarter, its order backlog increased by 12% year-on-year to 100.4 billion won, and in May the company also signed a contract to supply the PMS DAS for Hanul Units 1 and 2 worth 9.2 billion won. Wooree Technology is also working to secure new growth engines by participating in a range of small modular reactor (SMR) projects, in addition to large-scale nuclear power plants.

A Wooree Technology official stated, "We have once again proven our technical capabilities in core monitoring and data management for nuclear operation by winning this Kori Units 3 and 4 project, following our previous success with Hanul Units 1 and 2," adding, "Through thorough quality control and stable project execution, we will contribute to improving the safety and operational reliability of the power plant."
