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.

This paper deals with a new foam material containing polysytrene and its oxirane derivative. A monomer, 4-vinylphenyloxirane (M1), was prepared from 4-chlorostyrene. Polystyrene-based copolymers using styrene and M1 were prepared by free radical copolymerization using azo-bis(isobutyronitrile) (AIBN) as an initiator. The solutions of the obtained polystyrene-based copolymers in 4-chlorotoluene were gelated by the addition of a cationic initiator, which caused crosslinking via ring-opening polymerization of the pendant cyclic moieties. SEM images of the dried gel show various foam structures. The formation mechanism of the micro- and nano-structure was explained from the view point of the affinity of the monomer unit and the solvent. The homopolymer of 4-vinyphenylolxirane showed the finest and most uniform structure.
