Saean Engineering

What Saean Engineering does

Saean Engineering Corporation (세안기술(주)) is a Seoul-headquartered, privately held Korean nuclear engineering services firm founded in February 1997. The company specializes in non-destructive testing (NDT), inspection, and maintenance services for nuclear power plants and other high-temperature/high-pressure industrial facilities, organized around three core service lines: ultrasonic testing (UT), eddy current testing (ECT), and power plant equipment inspection and maintenance covering sludge lancing, foreign object search and retrieval (FOSAR), chemical cleaning waste treatment, and RCS piping inspection.

Its underlying technology rests on robotic remote-controlled inspection systems for high-radiation zones, vision-sensor-based real-time leak and vibration monitoring (Leakage & Vibration Monitoring System), and spent nuclear fuel canister drying and dry-storage container NDT systems. The portfolio is protected by 42+ registered Korean patents and supported by a Corporate R&D Center established in 1997 plus a Hwaseong Training Center for skills development. Saean holds KEPIC QAP, ASME NQA-1, ISO 9001/14001/45001/19443, and KOLAS calibration accreditation, all required for nuclear plant access.

Saean operates as a B2B/B2G professional services firm earning revenue through negotiated long-term contracts with government-owned utilities and enterprise nuclear operators, primarily Korea Hydro & Nuclear Power (KHNP) across all Korean plant sites, with supplementary international projects in the UAE (Barakah), USA, and Canada via partnerships with ANATEC, IIA, ZETEC, and others. The company sells proprietary equipment (e.g., spent fuel drying systems, vision-based monitoring) as part of service contracts and through its KOLAS-accredited calibration center. A 2018 corporate split created Saean Enertech Corporation as a separate entity for radiation-related operations. CEO Jae-Seok Park leads the firm.
