A new supercomputer named Bitterroot started operating in June at Idaho National Laboratory’s Collaborative Computing Center (C3) and is speeding up nuclear energy research by improving access to modeling and simulation tools. Bitterroot arrived at INL in March, and the announced July 15 that the supercomputer was open to users on June 18 after installation and an extensive program of testing.

While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use. Jenifer Shafer, the associate director for technology at the Advanced Research Projects Agency–Energy (ARPA-E), recently delivered a TEDx talk in which she explained the basic concepts of nuclear waste recycling, including related nonproliferation issues.

Fast burst reactors were the first fast-spectrum research reactors to reach criticality by using only prompt neutrons with high-enriched uranium as fuel, creating a pulse for microseconds. Among many achievements, fast burst reactors were the first research reactors to demonstrate the ability of thermal expansion to terminate a pulse and to show how this could aid in reactor safety.

Last year in late August, 120 storage cylinders of depleted uranium oxide (DUOx) safely arrived by rail in West Texas, having been shipped from the Department of Energy’s Portsmouth Site in Ohio. It was the first such shipment of the stable crystalline powder from the Portsmouth Site and was another milestone in the DOE Office of Environmental Management’s (EM) efforts to ship DUOx for off-site disposal.

The exterior of the Clementine nuclear reactor at Los Alamos Scientific Laboratory. (Photo: LANL)In March 1949—75 years ago this month—the 25-kilowatt reactor known as Clementine reached full power. As an experimental reactor, it had a rather long and successful run. It was the world’s first fast neutron (high-energy) reactor and operated from initial criticality in 1946 to final shutdown in 1952.
