Order number 940330-160606-96 -001-001 page 5 set 11 with 111 of 111 items 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.

CORPORATE TEXT Sandia National Labs., Albuquerque, NM (United States) PUB. DATE (YYMMDD) 930700 ~ LIMITATION CODE UNL 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 900348349
