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

PNNL’s contributions over the last year span scientific discovery, sustainable energy and national security.

Twenty years after the first radiation portal monitor was installed, PNNL continues supporting the Department of Homeland Security’s efforts to detect and prevent terrorist weapons from crossing our borders.

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

PNNL’s expertise is the foundation for monitoring technology that identifies trace amounts of radioactive materials and determines whether they are indicative of a nuclear explosion.

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.

Just reading the headlines makes it clear that these are anxious times.

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

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.

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.
