Located in Newmarket, Ontario, Curtiss-Wright Nuclear Canada (CWNC) is a product and service brand of Curtiss-Wright Nuclear, providing commercial grade dedication, equipment qualification, and project management services to support the local Canadian nuclear market and the international fleet of CANDU utilities. CWNC’s services include seismic testing and analysis, radiation testing, LOCA simulation, and thermal aging, as well as safety-related repair, refurbishment, and reverse engineering to extend the life of electrical and mechanical components. Additionally, CWNC manufactures a portfolio of conductivity cells and cell holders.

CWNC’s qualification center is fully equipped to perform testing in-house on a broad range of components and assemblies, and has been designated as a testing facility for the EPRI SQURTS program. Their tri-axial shaker table has a 10,000 lb. capacity and can be accelerated to 18g with frequencies of 200Hz. All seismic testing and analysis is consistent with the requirements of the CSA N289 series, the IEEE 344 standard, and the IEEE 323 standard. 

CWNC’s quality assurance program is NUPIC-audited, meeting both the CSA Z299.2-1985 + CSA N286-05 and 10CFR50 Appendix B requirements for Canada and the United States. CWNC is also certified by TSSA to N285 and CSAB51 for fabrication of welded and non-welded components.
