By combining computational modeling with experimental research, scientists identified a promising composition that reduces the need for a critical material in an alloy that can withstand extreme environments.

Researchers are developing and deploying solutions to reduce risk and increase efficiency while keeping people and the environment safe.

Summer is for science! PNNL’s interns are diving into science and technology and getting a front-row view of the research and development of a national laboratory.

Science and engineering solutions helping keep America safe from explosive, radiological, biological and cyber threats.

Researchers delivering new solutions to speed development and deployment of advanced reactor concepts.

Peering through the thick, green glass of a decades-old "hot cell," an expert technician manipulates robotic arms to study highly radioactive waste from Hanford, in support of ongoing cleanup.

Cleaning up Hanford is no easy task: it is one of the world's largest and most complex environmental remediation projects. The nation's top engineering firms are on the job and the Department of Energy's PNNL is helping.

Nuclear power figures prominently in our country's energy portfolio and is essential to our economic and environmental security.

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.

School's out, which means a new group of interns is settling into summer research assignments with mentors at the Department of Energy's Pacific Northwest National Laboratory in Richland.
