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 establish the 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 offallout from the
1986 Chernobyl nuclear reactor accident. The laboratory developed a process for encapsulating
highly. radioactive nuclear waste in vitrified glass and demonstrated the process on 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 deploymentof technology, with an emphasis _

on resolving environmental issues, such as waste remediation, and global environmental change.

When appropriate, PNL also performed workfor other federal agencies, such as the Department
ofDefense, 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 of which 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 meansofcontrolling its inactive records. The forms also list the
organization whichretired the records and indicate the larger collections of which boxes are a

part.

Originally some of PNNL's inactive records about site activities were classified. The Richland
Operations Office has now declassified many of these older documentsin response to litigation
and other needs. It has placed many of these documentsinits public reading room; thus, much of
the contents of the boxeslisted 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 Home Pageat http://www. hanford.gov/doe/readinghtm.
Inactive Records Produced by Pacific Northwest National Laboratory—Selected Examples
of Reactor Safety Research: The attached Records Transfer/Data Input forms list collections
which demonstrate research aimedat helping to insure the safety of commercial nuclear power
plants. Much of the work was performed for the Nuclear Regulatory Commission. Nuclear
