Nuclear power & SMR
+2.51%원자력발전·SMR
The nuclear power and SMR theme covers Korean companies involved in building and maintaining nuclear reactors, supplying reactor components and nuclear fuel, and developing small modular reactors, which are smaller designs intended to be factory-built and deployed in more locations. Korean investors group these companies together because South Korea has a long-established domestic reactor industry and has been exporting nuclear plant projects abroad, while global interest in carbon-free baseload power has renewed attention on the sector. Stocks in this theme are often discussed in relation to government energy policy and international reactor contracts.
