Another Nail in the Coffin of the Misguided MOX Program

, senior scientist

In the Fiscal Year 2018 omnibus spending bill passed by the House of Representatives yesterday and the Senate today, Congress is taking an encouraging step toward terminating the wasteful and dangerous Mixed Oxide (MOX) Fuel Fabrication Plant, under construction at the Savannah River Site in South Carolina. The MOX plant, if completed, would be used to dispose of 34 metric tons of excess plutonium from the U.S. nuclear weapons program by turning it into fuel for nuclear reactors. However, the project is decades behind schedule and is now expected to cost upwards of $50 billion—ten times the original estimate. Read more >

The “Versatile Fast Neutron Source”: A Misguided Nuclear Reactor Project

, senior scientist

The Union of Concerned Scientists (UCS) supports a moderate level of Department of Energy (DOE) research funding to make nuclear power safer and more secure—for example the agency’s program to develop accident tolerant fuels for nuclear reactors. Conversely, UCS does not support programs that not only would cost a lot of money, but also could make nuclear power more dangerous and less secure. That’s why the organization is troubled by a bill that was passed by the House of Representatives on February 13. Read more >

The Pyroprocessing Files

, senior scientist

The article by Ralph Vartabedian in the Los Angeles Times highlights the failure of the Department of Energy’s decades-long effort to chemically process a stockpile of spent nuclear fuel at Idaho National Laboratory, ostensibly to convert the waste to forms that would be safer for disposal in a geologic repository. A secondary goal was to demonstrate the viability of a new type of processing spent fuel—so-called pyroprocessing. Instead, it has demonstrated the numerous shortcomings of this technology.

UCS in Science: The NRC Must Act to Reduce the Dangers of Spent Fuel Pool Fires at Nuclear Plants

, senior scientist

In a Policy Forum article published in this week’s Science magazine, I argue, along with my co-authors Frank von Hippel and Michael Schoeppner, that the U.S. Nuclear Regulatory Commission (NRC) needs to take prompt action to reduce the alarmingly high potential for fires in spent fuel pools at U.S. nuclear plants.
