Let’s Get a Better Deal on Plutonium Disposition

President-elect Donald Trump has promised to renegotiate international agreements to get “better deals” for the United States. A good place for him to start would be the U.S.-Russia Plutonium Management and Disposition Agreement (PMDA), which obligates each country to dispose of 34 metric tons of excess plutonium from their military stockpiles, so the dangerous material cannot easily be reused for nuclear weapons. Collectively, this plutonium is enough for more than 15,000 nuclear bombs. Read more >

Nuclear Plant Security on the 15th Anniversary of 9/11: The Need to Remain Vigilant

Although the September 11, 2001, attacks are becoming a distant memory, it would be a big mistake to forget that the danger to the United States from both international and domestic terrorists remains very real today. Unfortunately, U.S. nuclear power plant owners are experiencing collective denial about their facilities’ vulnerability to sabotage attacks that could cause widespread radiological contamination.

Indian Point and a Victory for Sound Science at the NRC

UCS devotes a lot of ink to criticizing the Nuclear Regulatory Commission (NRC) for making bad decisions that reduce nuclear safety. So it is a refreshing change of pace to be able to praise the agency.  On May 4, the NRC commissioners did the right thing and voted to overturn a ruling by the Atomic Safety and Licensing Board in the Indian Point license renewal proceeding that, had it stood, would have set a terrible precedent for scientific integrity in regulatory decision-making.

The Perfect Gift for the Nuclear Security Summit

As the fourth and final Nuclear Security Summit convenes today, here’s an idea for a great parting gift that President Obama can offer to the international community. The United States possesses a unique asset that could be used to train nuclear security guards in a realistic setting: the partially built Mixed Oxide (MOX) Fuel Fabrication Facility at the U.S. government’s Savannah River Site (SRS) in South Carolina. Using this complex as an international training center would help strengthen global nuclear security and give new life to a facility that otherwise appears destined for the scrap heap. Read more >
