What Does North Korea Want—and What is the US Prepared to Give?

, co-director and senior scientist

North Korea is not likely to negotiate in earnest unless it is convinced the United States is committed to the process. It is important that the administration put together a package of what it is willing to put on the table in response to Pyongyang’s steps. Read more >

Another Nail in the Coffin of the Misguided MOX Program

, Acting Director, Nuclear Safety Project; Senior Scientist, Global Security Program

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 Case of the “Low-Yield” Trident Warhead

, Washington representative and senior analyst

Among the nuclear weapons programs included in the Trump administration’s Nuclear Posture Review, only one could start this year and be fully implemented in 2019. The military could field a “low-yield” nuclear warhead for the Trident missiles carried by US submarines.

What is this new warhead capability, and where does the proposal stand? Read more >

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

, Acting Director, Nuclear Safety Project; Senior Scientist, Global Security Program

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

, Acting Director, Nuclear Safety Project; Senior Scientist, Global Security Program

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.
