BWXT announces nuclear manufacturing plant expansion
BWX Technologies announced today plans to expand and add advanced manufacturing equipment to its manufacturing plant in Cambridge, Ontario, Canada.
A $36.3 million USD ($50M CAD) expansion will increase the plant’s size by 25 percent—to 280,000 square feet—and another $21.7 million USD ($30M CAD) will be spent on new equipment to increase and accelerate its output of large nuclear components. The investment will increase capacity and create more than 200 long-term jobs for skilled workers, engineers, and support staff, according to the company.

Was the death of the Yucca Mountain repository the fate of a technical lemon or a political lemon? We must be careful not to let this debate lure us away from capitalizing on the fruits of the project. One such fruit is a system for safely sealing packages containing radioactive nuclear waste. In March 2009, Idaho National Laboratory (INL) successfully demonstrated the Waste Package Closure System (WPCS), a full-scale prototype system for closing waste packages (WPs) that were to be entombed in the now-abandoned Yucca Mountain repository. This paper describes the system and components, which INL designed and built, to weld the closure lids on the WPs, nondestructively examine the welds using four different techniques, repair the welds if necessary, mitigate crack-initiating stresses in the surfaces of the welds, evacuate and backfill the WPs with an inert gas, and perform all of these tasks remotely. As a nation, we now have a proven method for securely sealing nuclear WPs for long-term storage - regardless of whether the future destination for these WPs will be an underground repository. Additionally, many of the WPCS's features and concepts may benefit other remote nuclear applications.
