The U.S. nuclear weapons laboratories have a program that allows their scientists and other researchers to conduct independent research and development (R&D) on subjects unrelated to the primary missions of the labs. This program—the Laboratory-Directed Research and Development (LDRD) Program—allows the labs to set aside up to 8% of their budgets each year for such R&D. Read More

Last December UCS, in collaboration with the American Association for the Advancement of Science (AAAS), held a one-day workshop on the safety and security of U.S. nuclear weapons. About 20 people participated, including active and retired scientists and engineers from Los Alamos, Lawrence Livermore, and Sandia National labs; representatives from NNSA, DOD and the State Department; independent scientists who are members of the JASON group that advises the government on nuclear weapons and other security issues; and experts from academia and nongovernmental organizations.

Considerable resources have been given to the safety culture at nuclear power plants and within the Nuclear Regulatory Commission (NRC) over the past decade. Safety culture is a challenging subject for nuclear technologists to handle because it does not lend itself to equations and computer analysis. Read More

The NRC’s process for handling allegations of safety problems at nuclear power plants was described in NEAT #8. Workers at nuclear power plants, as well as workers at companies providing goods and services to nuclear power plants, are protected by federal regulation from being discriminated against for having raised safety concerns.

In 2012, Congress demanded the Pentagon come up with recommendations for the location of a third site to base interceptors for the U.S. Ground Based Midcourse (GMD) missile defense system. So far no money has been appropriated for building a site (nor even for the next step in the study, an Environmental Impact Assessment of the top three candidates), nor has the Pentagon asked for any.

The nuclear nightmare at Fukushima Daiichi is the most recent in a string of nuclear accidents. In April 1986, the Unit 4 reactor at Chernobyl in the Ukraine experienced an uncontrolled increase in power that caused two “rapid disassemblies” – nukespeak for explosions. Read More
