Four nuclear reactors hit a big milestone in the US

The US nuclear power sector reached a significant milestone this Independence Day as four new microreactors achieved criticality, marking a key step in their operation. This accomplishment aligns with a goal set by the Trump administration to have three such reactors reach this stage by the end of last year. Achieving criticality signifies that the reactors can sustain a controlled nuclear chain reaction, a crucial step towards commercial deployment. This development is pivotal as it underscores the potential for advanced nuclear technology to play a role in the nation's low-carbon energy future.
