- The SC module will be utilized in Romania’s SMR project, with Samsung C&T expected to play a significant role in the main construction, strengthening technical competitiveness and securing leadership in the global SMR market.
- Meta Description: Samsung C&T Engineering & Construction Group has successfully demonstrated a new modular construction component for small modular reactors with a Steel-Composite (SC) module to be used in Romania’s SMR Project.

Samsung C&T Engineering & Construction (E&C) Group is accelerating its push into the global small modular reactor (SMR) market by showcasing a modular construction method for SMR structures.
During a recent completion ceremony, the Samsung C&T E&C Group completed a demonstration of a Steel-Composite (SC) modular wall for SMRs in collaboration with IHI Corporation, a leading Japanese heavy industry company.

Samsung C&T’s SC Module Mockup is Unveiled
The demonstration took place on May 27 at IHI’s Yokohama plant in Japan, with representatives from RoPower, a subsidiary of Romania’s SMR project developer Societatea Nationala Nuclearelectrica (SNN), U.S.-based Fluor and NuScale, and IHI in attendance. During the event, Samsung C&T unveiled the full-scale SC wall module and officially handed over the completed unit that will be used for the Romania SMR Project.

A New Modular Approach
Nuclear power plant walls are typically constructed onsite using formwork, rebar, and poured concrete. In contrast, Samsung C&T, working with IHI, produced a Steel-Composite (SC) wall using prefabricated steel plates filled with concrete, significantly enhancing structural safety.
Advantages of a Modular SMR Approach
The modular approach of fabricating components off-site and assembling them onsite aligns with the SMR project’s need to shorten construction schedules and reduce costs. The SC modular method offers key advantages, including enhanced safety, faster timelines, improved quality, and cost savings, positioning it as a core technology for SMR construction.
Samsung C&T Positioned to Take on Future SMR Projects
The Samsung C&T E&C Group is currently participating in the Front-End Engineering Design (FEED) phase of Romania’s SMR project. With the successful demonstration of this core construction method, the company is now expected to take on a significant role in the main construction phase. The achievement also positions Samsung C&T as a key player for participation in future global SMR projects.
Koo Won-seok, Executive Vice President of Samsung C&T’s Nuclear Business Team, stated, “The successful demonstration of the SC module further proves our technical expertise and project execution capabilities in the SMR construction sector. Building on this success, we aim to ensure the successful delivery of the Romania SMR project and strengthen our competitive edge in the rapidly growing global SMR market.”
