Summary
The government has confirmed Yeongdeok County in North Gyeongsang Province as the construction site for two new large nuclear reactors and Gijang County in Busan as the site for Korea's first small modular reactor (SMR). Because site selection marks the turning point at which a nuclear project moves from the planning stage into actual ordering and construction, it is an event that improves medium- to long-term work visibility across the entire nuclear value chain — from main equipment to design, construction, and maintenance.
What happened
Under this decision, the two new large reactors will be built in Yeongdeok, North Gyeongsang Province, while the first unit of the SMR — a next-generation reactor design nearing commercialization — will be located in Gijang, Busan. Gijang County is already Korea's largest nuclear cluster, home to a dense concentration of the Kori and Shin-Kori reactors, and the decision is read as placing the demonstration-oriented SMR in a region with accumulated operating experience and infrastructure.
Large reactors and SMRs are different in nature. A large reactor is a massive civil-engineering and equipment project requiring construction costs of trillions of won per unit, whereas an SMR is built by manufacturing modules in a factory and assembling them on site — a field where standardization and export scalability stand out. With both tracks securing sites simultaneously, the industry can now target two pillars at once: existing large-reactor work and the future SMR market.
Structural background
As policy direction has shifted from a nuclear phase-out stance to nuclear expansion, Korea's nuclear industry has entered a phase in which new construction and continued operation (lifespan extension) proceed in parallel. On top of this, rising global electricity demand combined with the power burden from data centers and AI is prompting a reassessment of nuclear power's standing as a carbon-free baseload source. The site confirmation is a signal that this trend is taking concrete shape through administrative procedures, and the timeline leading to environmental impact assessment, licensing, design, and ordering is now beginning to move.
Impact on stocks and sectors
- Doosan Enerbility: As Korea's sole maker of core main equipment such as reactors and steam generators, it is expected to benefit directly from both new large-reactor units and SMR module manufacturing. The confirmation of new sites is a key variable that improves visibility for future main-equipment orders.
- KEPCO E&C: Responsible for comprehensive nuclear design (reactor systems and overall design), it generates design work from the early stages of construction. Following site selection, revenue recognition begins at the front end as design orders flow through.
- KEPCO KPS: Handling reactor maintenance and commissioning, its long-term maintenance revenue base grows thicker as the number of new units increases. As a stock whose benefits come after units enter operation rather than during construction, it is a beneficiary with a time lag.
- Equipment and component stocks such as BHI, Woojin EnTec, and Iljin Power: As part of the cooperative value chain covering auxiliary equipment, instrumentation and control, valves, and maintenance personnel, their order momentum may be reflected in a distributed manner once ordering gets into full swing.
- KEPCO (Korea Electric Power): As the ordering and operating entity, it carries both construction-cost burdens and electricity-tariff structure, placing it in a two-sided position where cost and tariff variables must be weighed alongside any straightforward benefit.
Bull vs. bear scenarios
On the bullish side, the key point is that site confirmation is the starting point of a timeline running through environmental assessment, licensing, design, and main-equipment ordering. If two new large reactors and the SMR demonstration proceed simultaneously, work for main equipment, design, and maintenance will be recognized in a distributed manner over many years, and SMR standardization experience could also serve as a future export reference.
Conversely, the bearish variables are clear. Between site selection and actual groundbreaking, several stages remain — environmental impact assessment, licensing, and consultations on local acceptance — so the possibility of schedule delays is ever-present. Nuclear policy is an area of high volatility depending on the administration and public opinion, posing policy-continuity risk, and many nuclear stocks may have already priced in policy expectations, leaving accumulated valuation burdens. It is also worth keeping in mind that site confirmation does not immediately mean an order contract.
Action points for investors
- Check the timing and contract scale of actual order announcements for large-reactor main equipment and design to gauge whether expectations are converting into earnings.
- For SMRs, distinguish theme from substance based on progress against concrete milestones such as design approval and demonstration schedules.
- Track the order backlog of related stocks and the trend in nuclear-segment revenue and profitability at the next quarterly earnings release.
- Follow the environmental impact assessment and licensing schedules as well as policy decision announcements to price in delay and change risks in advance.
