Progress continues on a new utility shaft at the Department of Energy’s Waste Isolation Pilot Plant in New Mexico as shaft-sinking crews recently surpassed the midway point at a depth of 1,076 feet. When complete, the full shaft depth will be 2,275 feet, with the team now halfway to the WIPP repository depth of 2,150 feet.

According to the Department of Energy’s Office of Environmental Management (EM), shipments of transuranic waste to the Waste Isolation Pilot Plant in New Mexico are back to pre-pandemic levels, with the deep underground repository receiving 12 shipments in one week this summer.
Producing packages for radioactive materials takes time, attention to detail, and a thorough commitment to quality assurance.

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.”
