도입부: In this issue: Southern Nuclear’s Ho Nieh nominated to the NRC, Idaho National Laboratory and ALARA, a new analysis of China’s nuclear sector from Johns Hopkins, Caputo’s resignation from the NRC, and more.

INL makes a case for eliminating ALARA and setting higher dose limits

A report just released by Idaho National Laboratory reviews decades of radiation protection standards and research on the health effects of low-dose radiation and recommends that the current U.S. annual occupational dose limit of 5,000 mrem be maintained without applying ALARA—the “as low as reasonably achievable” regulatory concept first introduced in 1971—below that threshold.

China launches fusion-focused company

China has established a state-owned fusion energy company, China Fusion Energy Co., as a subsidiary of the China National Nuclear Corporation with the goal of accelerating the commercialization of fusion energy. According to a report by People’s Daily Online, the new company has a registered capital of 15 billion yuan (about $2.1 billion). Go deeper on Nuclear NewsWire.

How can radiation protection professionals support the global demand for nuclear energy?

The nuclear industry is being pushed forward by a global tailwind that includes plans for more conventional nuclear plants and an exciting trend toward developing small modular reactors. These include advanced safety features and novel reactor designs, often powered by new types of fuel. Read Mauritius Hiller’s full article on Nuclear NewsWire.

TBT: The reactor not built at Fermi

Twelve years after the world’s first breeder reactor (EBR-1 in Idaho) reached criticality, the 66-MWe Fermi-1, a liquid metal fast breeder reactor, entered operation in Monroe County, Mich., in 1963. Fermi-1 was the first LMFBR power reactor in the U.S. While the prototype pushed forward our understanding of breeder technology, it suffered a partial meltdown only three years into its life. After extensive repairs, the reactor restarted in 1970, only to be permanently shut down in 1972. Fermi-2: While Fermi-1 was plagued with issues, its successor has been a different story altogether. Fermi-2 is a 1,205-MWe boiling water reactor, a GE BWR-4, that entered commercial operation in 1985. Unlike its predecessor, Fermi-2 has had only minor issues and is still helping power Michigan today. Fermi-3: DTE Energy, the owner of Fermi nuclear power plant, began planning Fermi-2 in 1968. In 1972, the company expanded its plans by ordering Fermi-3, a companion GE BWR-4, to be built at the site. The company spent roughly $7 million (approx. $50 million in 2025 dollars) in siting and engineering studies, but development plans were indefinitely postponed by 1974 and by 1975 were permanently cancelled. So, why was Fermi-3 scrapped? One reason DTE gave at the time was a concern that changing federal regulations would force them to “start from scratch” on licensing activities. Those changes came from the abolition of the Atomic Energy Commission and the creation of the Nuclear Regulatory Commission, which was codified in the Energy Reorganization Act of 1974. Changing tides: Today, there is a chance that Fermi-3 will not be left in the dustbin of history as a reactor unbuilt. The NRC approved a combined operating license in 2015 that permits DTE to build another large plant at the site. In April, a spokesperson for the company told state legislators that direct federal and state support could see the company embarking on a new build.

To read the cancelation announcement of Fermi-3, see the August 1975 issue of Nuclear News (p. 40). (ANS members only)
