PNNL, located at Richland, Washington, is one of 10 U.S. Department of Energy national, multiprogram laboratories. Though it has shrunk from earlier times, PNNL is still a major lab, and employs about 3,600 staff members, with an annual budget of more than $200 million. PNNL conducts research in nearly every field of basic science to solve problems in the areas of the environment, energy, health and national security. Currently laboratory staff are engaged in over 1,000 research projects for the DOE, other federal agencies and private clients. Associated with the Hanford Nuclear Reservation, to which it is adjacent, PNNL is operated by Battelle Lab, a nonprofit R&D lab that is involved in numerous government and private R&D projects.
