New Insights from Old Glass

How might getting old—really old—affect the glass waste form chosen to immobilize radioactive waste at the Hanford Site in southeastern Washington state? Researchers are seeking answers from walls containing ancient glass in Europe. These walls, known as hillforts, are defense structures that date as far back as the Bronze Age. The researchers progress is the cover story in the May 2016 American Ceramic Society Bulletin.

PNNL Making Cleaner and More Efficient Vehicles

As Tri-Citians, we're fortunate that we don't have the frustrating traffic and long commutes that our friends in Seattle and Portland endure. And with lower prices at the pump, we don't think much about fuel efficiency.

New Watts Bar Reactor Gets Green Light for Operations

On October 22, the U.S. Nuclear Regulatory Commission (NRC)​​​​​​​granted Tennessee Valley Authority's (TVA's) Watts Bar Nuclear Generating Station a 40-year operating license for its new Unit 2 reactor. This is the first nuclear reactor to be granted an operating license by the NRC in two decades.

Corrosion Cracking: When Does it Really Start?

Pressurized water nuclear reactors in the United States generate about 13 percent of U.S. electricity. Though efficient, these reactors face a unique challenge with stress corrosion cracking (SCC). This type of corrosion is one of the primary life-limiting degradation mechanisms of nickel-base alloy pressure boundary components, such as instrumentation and control rod nozzles, the welds that attach these nozzles to the reactor vessel, and welds that connect feedwater piping to the reactor vessel. As interest grows in a more sustainable and efficient fleet of nuclear reactors across the world, there is increasing interest in characterizing SCC initiation response.
