Rishi Sunak, U.K. prime minister, announced plans this week to boost Britain’s nuclear workforce by 40,000 to support submarine building and developing other aspects of the nuclear energy industry.

“In a more dangerous and contested world, the United Kingdom’s continuous at-sea nuclear deterrent is more vital than ever,” Sunak said in a statement. “Today we usher in the next generation of our nuclear enterprise, which will keep us safe, keep our energy secure, and keep our bills down for good.”

More information about the government’s plans are laid out in the Defence Nuclear Enterprise Command policy paper.
