How we work

Our in-house Engineering department houses engineers whose control system knowledge covers a broad range of control system platforms from many vendors and whose experience spans numerous industries, including nuclear, aerospace, petrochemicals, automotive, and manufacturing. Our engineers are skilled in designing and developing a wide-range of control systems: from Distributed Control Systems (DCSs) and Independent Control Systems (ICSs) to standalone single-loop controllers. In addition, we have experience in PLCs, HMIs, SCADA, data historians and plant information systems.

Quality Assurance

It has been a long term policy of Alithya to deploy independent verification and validation teams to ensure that review and testing is performed with the proper degree of objectivity and to provide a division of labour that compresses project timelines and uncovers errors early.

Alithya has a proven track record of performing qualification of pre-developed/Commercial-Off-The-Shelf (COTS) software components and related software engineering tools, and helping nuclear operators and suppliers comply with regulatory requirements of the Canadian nuclear industry with respect to computer systems. Our expertise includes involvement in authoring COG-95-179, CSA N290.14-07 and CSA N290.14-15.

Our quality process is embodied in the Alithya Nuclear Quality Management System (NQMS).

NQMS has been successfully audited by CANDU Procurement Audit Committee (CANPAC) and/or OPG against the following nuclear standards: CSA N299.1, CSA N286-12 and CSA N286-05, CSA N286.7-16 and CAN/CSA Q396.1.1, CE-1002-STD (Category II Software Engineering), and CE-1003-STD (Category III Software Engineering)

Engineering Lab Capabilities

Alithya’s Engineering Technology lab serves as a research, prototyping, development, and testing centre for all in-house projects related to computer/control systems and custom hardware. This allows us to provide complete turnkey systems qualified to nuclear standards.

Technical Resources

Simulation software, OPC servers, HMIs, and PLCs are some of the development tools used to integrate software with hardware components. With these resources readily available, Alithya can perform rapid prototyping, development, testing, and integration all on site.

Nuclear Ready Control Systems

We deliver safe, reliable, cyber-secure, nuclear-ready control systems by leveraging our expertise in Nuclear Engineering Change Control (ECC) process, Software Engineering standards (Category 1, Category 2, Category 3), Software and hardware qualification standards (CSA N290.14), Cyber Security standards (CSA N290.7) and Extensive domain experience.
