Southern Nuclear last Friday announced that its Vogtle Unit 2 reactor has become the first U.S. commercial reactor to be authorized by the Nuclear Regulatory Commission to use accident tolerant fuel exceeding 5 percent uranium-235 enrichment.

China’s Taishan-1, which was shut down last summer due to damaged fuel rods, resumed operations on August 15.
The plant briefly made headlines last summer—as much for the damage inside the reactor as for the media fallout. In June 2020, plant operators found damage to the cladding on about five of the 60,000 fuel rods in Taishan-1, one of the plant’s two 1,660-MW EPRs. What happened next seemed like a bad game of “telephone.”

If Taishan-1 were operating in France, Électricité de France would shut down the reactor in order to assess the situation in progress and stop its development, according to a July 22 press release from EDF. The 1,660-MWe French-designed EPR—the recent subject of sensational press coverage of fuel rod failures—operates in China’s Guangdong Province.

The facts, once known, were uncomplicated. At Taishan-1 in China—the first Framatome EPR to be commissioned—operators detected an increase of fission product gases within the primary coolant circuit sometime after the reactor’s first refueling outage in October 2020. The cladding on a handful of the more than 60,000 fuel rods in the reactor had been breached, posing an operational issue—but not a public safety issue—for the plant.

Today’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.
