도입부: In this issue: The NRC proposes a new rule on microreactors, EDF will invest $117 million to bolster the nuclear supply chain, South Africa looks to build its nuclear workforce, and more.

NRC introduces microreactor regulatory framework

The Nuclear Regulatory Commission has released a new licensing framework for microreactors and similar reactor designs that may provide a more suitable pathway for applicants with simpler technologies. The proposed rule—known as Part 57—is the latest to come out of the NRC’s rules review and overhaul stemming from the ADVANCE Act and 2025 nuclear-related executive orders.

Nuclear trivia—reveal

The answer: In 1958, the USS Nautilus, the world’s first nuclear submarine, became the first ship to reach the North Pole. As the ship that birthed the nuclear navy, the Nautilus today maintains a legacy as one of the most important nuclear projects of the 20th century. A brief background: While the history of submersible vehicles goes surprisingly far back in history (see the USS Alligator of the American Civil War or even various, rudimentary designs all the way back in the Middle Ages), the Nautilus sought to solve the inherent issues of the diesel-electric systems used in the early 20th century. These designs were held back by a constant need to surface and recharge the vessel’s batteries—an issue that nuclear power was poised to make irrelevant. The Nautilus project was authorized by Congress in 1950. Work on a prototype reactor began in 1951 at the National Reactor Testing Station (which would go on, after many name changes, to become Idaho National Laboratory. On May 31, 1953, that prototype reactor was brought to power. In a matter of weeks, a 66-hour, full-power run of the reactor was successfully completed. According to an article in the May 1969 issue of Nuclear News, this first test was “equivalent to a nonstop underwater trip from Newfoundland to Ireland at top speed.” On January 21, 1954, the Nautilus was launched into the Thames River in Connecticut. Four years later, the ship and its crew successfully circumvented the polar ice cap, reaching the North Pole on August 3, 1958.
