President Joe Biden, as you’ve no doubt heard, has had a rough few weeks. Yet on Tuesday, he signed a bill into law that could well prove transformative for America’s energy future. Here’s hoping — whatever happens in November’s election — that more progress lies ahead.

Known as the Advance Act, the bill seeks to remedy some long-standing flaws in nuclear-energy regulation. To reach net zero, the world will need to roughly double its nuclear capacity by 2050, according to the International Energy Agency. Yet constructing new nuclear plants in the US is expensive, time-consuming and encumbered by red tape. Partly as a result, the industry has stagnated: The share of electricity generated by nuclear is projected to decline to about 12% by 2050, from about 18% today.

The Advance Act should help reverse that trend. As a start, it makes useful reforms to the Nuclear Regulatory Commission, allowing the agency to hire more staff, reduce licensing fees, speed application processing and ease the burden of environmental reviews. It also makes a small but consequential change to the commission’s mission, requiring it — after decades of focusing on potential threats — to also consider the vast public benefits of nuclear energy when making regulatory decisions.
