Oak Ridge National Laboratory Institutional Plan: FY 1982-1987

16 Oak Ridge National Laboratory Institutional Plan FY 1982-FY 1987
tokamak stability in collaboration with the Impurity
Study Experiment (ISX-B) program. In the EBT
area, the efforts to model confinement will continue,
and, in particular, the effects of high-core plasma
beta will be studied. Efforts are increasing in the
area of advanced toroidal concepts; emphasis is on
the effects of externally applied helical fields.
Work continues in an applied plasma physics effort
to develop advanced laser diagnostics. For example, a
multichord Faraday rotation system that measures the
plasma current profile on ISX-B has been developed
and should begin providing data in FY 1982.
Activities pertaining to atomic physics data will
continue analyzing and disseminating important data
for the fusion community and, where needed, will
measure cross sections of multicharged ions.
Tokamak Systems (AT 10 10). The ISX-B
device continues to produce critical information for
the tokamak program. High-beta studies of circular
and noncircular plasmas continue, as well as parallel
programs in pellet fueling, impurity studies, electron
cyclotron heating, magnetic ripple effects, and diag
nostic development. In FY 1982 a bundle divertor
and improved diagnostics will be installed. We
expect the ISX-B program to continue into 1984.
As a result of broadened interest shown by other
laboratories and DOE in improving the tokamak con
cept, the ISX-C program and device are being
modified and renamed ATF to emphasize the study of
improved toroidal confinement features. Included will
be studies of the effects of helical coils on stability
and confinement and of the principles of steady-state
operation. The ATF operation should start in 1985.
Development and Technology (AT 15). The
major development activities in this area are super
conducting magnets and neutral beams. The delivery
of the first three coils for the Large Coil Program
(two from the United States and one from Japan) is
expected in mid FY 1982, and testing should begin
early in FY 1983. The remaining U.S. coil and the
two other international coils (from Euratom and
Switzerland) should be delivered in FY 1983 and
should lead to full-scale tests in FY 1984. Develop
ment work on high-field conductor and magnet
designs suitable for high-field tokamak magnets will
continue.
The Poloidal Divertor Experiment (PDX)/ISX-B
neutral-beam development activity has been com
pletely successful. Develop ment in the area of long-
pulse beams, in support of the MFTF-B device at
Lawrence Livermore Natonal Laboratory and ATF,
has begun and will contii ae through 1984. Efforts
in the areas of radiofrequency heating technology and
negative ion-based neutral beams are expected to
increase. In addition, significant work is in progress
on (1) developing materials for fusion reactors, (2)
developing accelerators that use solid hydrogen pellets
to fuel plasma devices, (3) characterizing the plasma-
wall interaction, and (4) developing techniques for
calculating neutron transport in complex geometries
and for checking the calculations against experimental
results.
The Fusion Engineering Design Center (FEDC) has
completed a preliminary design of the Fusion
Engineering Device (FED) and is preparing to colla
borate in expanded studies during FY 1982 and
1983. The FEDC's future role is being discussed.
Design studies of the FED and of the tokamak and
EBT demonstration reactors serve as a focus for the
plasma physics experiments and for technology
development.
Finally, a first draft of a generic environmental
impact statement for magnetic fusion power systems
has been prepared and will continue to be refined.
Biomedical and Environmental
Research (HA 02)
This activity encompasses a broad effort to under
stand the interaction of energy-related pollutants with
living organisms, including their transport, chemical
evolution, and ultimate fate in the environment. The
similarity of the environmental processes controlling
the fates of many different pollutants makes a broad
approach especially productive. Sedimentation and
sediment transport are studied to define the principal
reservoirs and vectors of pollutants; this information
is being used in ongoing DOE activities to ensure that
they are conducted safely and effectively and that
potential hazards to humans and ecological systems
can be identified, evaluated, and anticipated. One
