Small nuclear reactors are pitched as cheaper, safer, faster and easier to finance than their conventional counterparts. Hype around them is building fast, but some experts warn it ignores fundamental

Denmark is considering building small modular nuclear reactors to meet its energy needs, the climate and energy ministry said Thursday, which would bring an end to its 1985 ban on nuclear power.

Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons. Those bump into other atoms, splitting them and causing them to emit more neutrons, which bump into other atoms, continuing the chain reaction.

Fireplaces are cozy until it’s time to shovel out the ashes. Nuclear power has the same problem: abundant, reliable energy paired with a growing pile of difficult-to-discard spent fuel. But a new reactor design aims to “burn” part of that nuclear ash by turning certain spent fuel back into usable energy.

The federal government is sending enriched uranium to a nuclear company that aims to build next-gen salt-cooled reactors in Oak Ridge.

For decades, Hawaiʻi has said no to nuclear power. But advancements in nuclear technology and pressures to shift Hawaiʻi away from costly oil have prompted some lawmakers to revisit the nuclear question.

Gov. Kathy Hochul plans to pursue perhaps the most ambitious development of nuclear power in America, setting a new goal to build five gigawatts of new nuclear capacity instead of just the one gigawatt she announced last June.

The massive corporate handout was approved despite strong opposition from organizations across the state, as well as the Onondaga, Tonawanda Seneca, Mohawk, and Tuscarora Nations due to the impacts of nuclear power on their lands and treaty rights.
