Nuclear power is on the brink of a 1 trillion-dollar resurgence, but one accident anywhere could stop its momentum.

Nuclear energy is at an inflection point. Early exuberance about its potential was undercut by a series of devastating and dangerous accidents: Three Mile Island in Pennsylvania in 1979; Chornobyl in Ukraine in 1986; and Fukushima Daiichi in Japan in 2011.

But now, thanks to new technology and the increasingly urgent need to fight climate change, nuclear energy is getting a second shot at becoming a prominent part of the global energy grid. That’s because nuclear energy generation does not create any of the dangerous greenhouse gas emissions that cause climate change.

In a panel discussion at the United Nations on Tuesday, a collection of nuclear energy leaders from around the world gathered to discuss the scope of that renaissance and why it’s so critical that the industry work together to ensure gold-standard safety measures are adopted everywhere.

A nuclear accident anywhere has the potential to upset the most major momentum the nuclear industry has had in decades.
