July in the Tri-Cities usually brings sunny skies, hot weather and high demand for electricity as many of us retreat to air-conditioned homes and offices.
In fast-neutron reactors, fuel is sealed in ~7 millimeter diameter steel tubes called cladding. When a high-energy "fast" neutron strikes an atom in the steel, it can knock the atom out of place, like a cue ball striking another billiard ball. This leaves two types of damage in the metal: an empty spot where the atom was, and the displaced atom wedged between other atoms. Over time, these defects typically drive undesirable rearrangement of the microstructure, potentially reducing the life of the cladding.
Cybersecurity is increasingly top-of-mind and in the news. Individuals worry about identify theft and the compromise of financial and medical records. And the federal government battles myriad threats aimed at our national security.
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.
Steve Jobs said, "Innovation distinguishes between a leader and a follower." That is especially true in research and development. New technologies and creative solutions do not materialize overnight or on their own.
Discovery in action. These words describe what we do at PNNL. For more than 50 years, we have advanced the frontiers of science and engineering in the service of our nation and the the world.
PNNL takes pride in advancing scientific frontiers and developing solutions to vexing problems. In particular, we apply our technical expertise to address national needs in security, energy and the environment.
As a Department of Energy national laboratory, you would expect Pacific Northwest National Laboratory to perform research in chemistry, physics and engineering in support of our energy, environmental and security missions.
Scientists have made a "vitamin mimic" - a molecule that looks and acts just like a natural vitamin to bacteria - that offers a new window into the inner workings of living microbes.
PNNL will manage the newly formed Lightweight Materials National Lab Consortium or LightMAT – a network of nine national labs with technical capabilities that are highly relevant to lightweight materials development and use.
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.
Calcium carbonate found in chalk, shells and rocks is one of the most important materials on earth. New insights on how it turns into hard, strong materials will help scientists design materials needed for a low-carbon future.
Enjoying the beauty of science year-round is easy with a new digital calendar and computer wallpaper containing captivating images that illustrate research at PNNL.
