Atoll
\
(USAKA) Base. The USAKA Base is locatéd on
Kwayalein Atoll, Republic of the Marshall Islands, which
is over 2100 miles west of Hawaii in the southern North
Pacific. HAZWRAP was tasked to devise a scheme for
disposal of polychlorinated biphenyl (PCB) -contaminated
transformer fluids. Alternatives to incineration were
sought because of the remote location, harsh marine
environment, and difficult logistics in transporting
PCB-contaminated materials to the United States for
disposal. Many of the transformers on Kwajalein Island
contain askarels in the range of 300,000- to 700,000-ppm
PCB. A surgery of PCB disposal methods identified
thermal destruction as the only available and permitted
process for destroying very high-concentration PCB
fluids. The economics and risk associated with
transportation make this option unattractive. Existing
chemical destructive methods are permitted for <10,
000-ppm PCB and result in incomplete degradation of PCB.
A new chemical method referred to as base catalyzed
destruction
(BCD)
was developed by scientists at the
Environmental Protection Agency Reduction Engineering
Laboratory. The BCD chemical reaction will destroy PCBs
in excess of 100,000 ppm. This emerging technology was
not at the process or demonstration phase of
development. HAZWRAP tasked scientists and engineers
from Oak Ridge National Laboratory to develop and scale
up the process. These efforts will result in a mobile
chemical
reactor unit that
can be transported to remote
locations and decontaminate high-concentration PCB
fluids on-site.

ABSTRACT
A mission hazard assessment has been performed for the
Strategic Target System Mission 1 (known as STARS M1)
for hazards due to potential debris impact in the
Marshall Islands area. The work was performed at Sandia
National Laboratories as a result of discussion with
Kwajalein Missile Range (KMR) safety officers. The STARS
