Governments are accelerating the development of small modular reactors (SMRs) as part of a global nuclear power revival, with the U.S. taking the lead in microreactor technology. SMRs, with capacities up to 300 MW(e), are modular and factory-produced, making them cheaper and faster to construct than traditional reactors. They are designed for smaller sites and can be incrementally deployed to meet energy demands.
Microreactors are even smaller and can be transported easily, making them suitable for rural areas and emergency response scenarios. These reactors can operate for up to 10 years without refueling and are expected to have simple designs that enhance safety.
In the U.S., the Department of Energy supports various advanced reactors, including microreactors, as part of a push to quadruple nuclear power production by 2050. Recently, companies like Aalo have achieved significant milestones in reactor development.
The U.S. Army is spearheading microreactor initiatives per Executive Order 14299 to establish operational reactors by 2028. With plans to invest $2.2 billion in partnerships for new reactors at military bases, the army aims to catalyze the development of advanced nuclear technologies across the country.
Government support and favorable regulations are expected to spur rapid advancements in microreactor technology over the coming years.
