Once again, the U.S. fleet has achieved a new personal best, even as utilities and operators face formidable challenges.
In the early years of the Nuclear News capacity factors survey, any factor over 70 was deemed excellent; any factor under 50 was considered poor. By that standard, all but two operating U.S. power reactors chalked up excellent performance during 2017–2019. A record 809.4 TWh of electricity was generated in the United States from nuclear energy in 2019, according to the U.S. Energy Information Administration (EIA), besting the record of 807.1 TWh set in 2018.
Nuclear News staff developed the capacity factors survey in the early 1980s as a way to identify the most productive reactors in an expanding fleet. Fleet improvement was the industry’s self-identified goal, but no one could anticipate the startlingly rapid pace of improvement, spurred by the Institute of Nuclear Power Operations (INPO), which boosted fleetwide performance to highs that continue today.
Producing packages for radioactive materials takes time, attention to detail, and a thorough commitment to quality assurance.
The Optimus-H transport cask on display at the 2020 Waste Management Conference in Phoenix, Ariz.
Jeff England, director of transportation projects for NAC International, pointed to the large stainless steel canister, which looked like a giant-sized silver dumbbell, perched on the flatbed of a semitrailer truck parked in the middle of the expansive exhibit hall in the Phoenix Convention Center. NAC, a provider of nuclear storage, transportation, and consulting services, was using the 2020 Waste Management Conference, held March 8–12 in Phoenix, Ariz., to unveil its newest transport casks, the Optimus-H and Optimus-L.
“These are a different niche,” England said of the casks, which were designed to transport radioactive materials, including remote-handled transuranic waste, high-activity intermediate-level waste, low-enriched uranium, and fissile materials. “You have a lot of [small] drum-sized packages, and you also have a lot of big packages that will hold around 10 55-gallon drums. But there’s not anything in between. We hold a 110-gallon drum capacity.”
