Sealaska Technical Services Awarded Major Contract wtih U.S. Department of Energy's National Nuclear Security Administration

Sealaska Technical Services (STS), LLC announced today that will participate in a joint venture with Tetra Tech was selected to provide design-build services to the U.S. Department of Energy’s National Nuclear Security Administration (NNSA). Under the Design, Integration, Construction, Communication, and Engineering (DICCE) contract, the joint venture will share in the $400-million contract over the next seven years.

The DICCE Contract is administered by NNSA’s Office of Nuclear Smuggling Detection and Deterrence (NSDD) (formerly Second Line of Defense) whose mission it is to strengthen the capabilities and commitment of U.S. partner countries to deter, detect, and interdict illicit trafficking of nuclear and other radioactive materials within the interiors of partner countries, across international borders, and through the global maritime shipping system.  This U.S. government nuclear nonproliferation program provides partner countries with the tools and training necessary to counter nuclear smuggling, thus making an essential contribution to the global nuclear detection architecture. It does this by installing radiation detection systems at high-priority locations around the world and by building a community of states that possess an indigenous capacity to deter, detect, and interdict nuclear and radioactive materials.

The joint venture team will provide design-build services to support the installation and deployment of fixed and mobile radiation detection systems and associated infrastructure at border checkpoints, airports, seaports, internal country locations, and maritime borders outside of the United States.

“Sealaska is honored to have the opportunity to continue to help NNSA achieve its critically important global security goal of reducing the threat of nuclear and radiological terrorism,” said Anthony Mallott, Sealaska President and CEO. “We look forward to working with the NNSA and our joint venture partner to make the world a safer place.”
