PNL continued its role as an expanding and diversifying facility under DOE. When MountSt. Helens erupted in 1980, PNL began collecting and analyzing ash samples to determine potential environmental and health consequences. The laboratory fabricated special bundles of reactor fuel rods to help to determine what happens to nuclear fuel rods during a reactorloss of coolant accident. PNL helped DOEto establishthe first Atmospheric Radiation Measurement site to obtain data related to global environmental change. It prepared a unique booklet explaining potential radiation hazards to help the people ofEnewetak Atoll to understand health risks of returning to their native islands, the site of many earlier open-air United States nuclear weapons tests. PNL used its own Grumman Gulfstream I aircraft to collect air samples of fallout from the 1986 Chernoby! nuclear reactor accident. The laboratory developed a process for encapsulating highly radioactive nuclear wastein vitrified glass and demonstrated the process ona pilot-plant scale employing spent fuel from a commercial power reactor. PNL also performed lead laboratory roles for DOE on the Aquifer Thermal Energy Storage Program, wind energy, nuclear waste materials characterization, and nuclear waste management. By 1992 PNL employed more than 3,500 people, had an annual budget of over $500 million, and supported energy, environmental, health, educational, and national security missions. It focused on scientific research and the rapid development and deployment oftechnology, with an emphasis on resolving environmental issues, such as waste remediation, and global environmental change. When appropriate, PNL also performed work for other federal agencies, such as the Department of Defense, the Nuclear Regulatory Commission, and the Environmental Protection Agency. In 1995 it was designated Pacific Northwest National Laboratory (PNNL). , Inactive Records Produced by Pacific Northwest National Laboratory: PNNL has custody of inactive records created by its own organizations and by General Electric. Like the Richland Operations Office, PNNL generally controls inactive records on the box level. PNNL, however, usually retains information about the collections ofwhich records boxes are a part. The attached Records Input/Data Transfer forms are inventories of the folders which appear in records boxes. PNNL uses them as one means of controlling its inactive records. The forms alsolist the organization which retired the records and indicate the larger collections of which boxes are a part. Originally some of PNNL's inactive records aboutsite activities were classified. The Richland — Operations Office has now declassified many ofthese older documentsin response to litigation and other needs. It has placed many of these documentsin its public reading room; thus, much of the contents of the boxes listed on the attached Records Input/Data Transfer forms may be available in the Richland public reading room. As soon as the documentsare available, they are linked to the Hanford HomePageat http://www. hanford.gov/doe/reading.htm. Sy Inactive Records Produced by Pacific Northwest National Laboratory—Selected Materials on the Effects of Plutonium Production: The attached Records Transfer/Data Input forms list some of the most important recordsin the custody of the laboratory. They contain documents related to the environmental and health effects of plutonium production at Hanford. They also
