A joint venture (JV) comprising BWX Technologies and Aptim has secured a $140m extension contract from Bechtel Marine Propulsion Corporation (BMPC) to conduct site decommissioning operations.

The current two-year extension deal also includes a $14m option, which is expected to be awarded to the company next year.

Additionally, the deal features an option for a third year of work at a value that will be negotiated in the future.

BWX Technologies president and chief executive officer Rex D. Geveden said: “BWXT takes immense pride in supporting the nuclear navy through this important infrastructure support and decommissioning programme with our partner APTIM.

“We have a very successful track record at the Naval Nuclear Propulsion Programme (NNPP) sites, and we look forward to continuing these efforts through BMPC.”

BWSR carries out comprehensive decommissioning and demolition (D&D) and infrastructure support work on complex systems, components and nuclear work facilities at BMPC-managed NNPP sites.

The company has performed high-consequence D&D and infrastructure support work at these project sites since October 2010.

Work to be conducted under the deal includes the complete demolition of inactive facilities and the removal of complex systems in operating nuclear facilities, which is expected to facilitate the installation of new systems without compromising the sites’ ongoing operations.

The current contract extension is slated to take effect from 1 October.
