UNENE R&D Workshop offers a glimpse into the future
MARCH 15, 2022 – The University Network of Excellence in Nuclear Engineering (UNENE) brings industry, academia and government together for collaboration that drives excellence in nuclear industry engineering, operations and research.
Nuclear power is a key ingredient in clean energy systems that are low in carbon and provide large amounts of electricity for the clean energy economy of the future. Continually improving and driving innovation of nuclear technologies will help us ensure all people can benefit from this important source of electricity as we strive to reduce and eliminate carbon emissions from our energy supply.
Through UNENE’s three-day seminar, participants learn about the latest developments in government direction, industry investment and activities as well as what researchers are working on in the labs to inform policy, business and career decisions.
UNENE’s last workshop in December 2021 was no exception. Thanks to a great lineup of industry experts, academic researchers and students presenting their work over three days, that collaboration once again resulted in new connections and discoveries.
Through the summaries below and links to recordings of the sessions, UNENE offers everyone a chance to strengthen their knowledge about the latest in nuclear developments.

Industry Research Chair presentations
Nuclear Safety Analysis and Nuclear Reactor Safety and Thermalhydraulics
Dave Novog, McMaster University
Professors Dave Novog and John Luxat head up the Nuclear Safety Analysis and Nuclear Reactor Safety and Thermalhydraulics Industrial Research Chair (IRC) at McMaster University. At UNENE’s R&D Workshop in December 2021, Novog described the program, which is in its final year before potential renewal, as intensive and wide-ranging. The underlying theme of the IRC is uncertainty analysis and applications, but the focal areas of the project have evolved over the years to take on different topics. Notably, the impact of Fukushima has increased the focus on severe accident methodologies and emergency planning, as well as safety and risk analysis and computational assessment tools. Novog also highlighted the importance of collaboration with industry partners. “None of these projects would be successful without our partners. We continue to use industry as both a research collaborator and also a training collaborator for the students involved.”

The Need for Innovation to Build SMRs – and Fight Climate Change
Robin Manley, Vice President, New Nuclear Development, OPG
In his role Vice President of New Nuclear Development at Ontario Power Generation (OPG), Robin Manley is accountable for the implementation of small modular reactors (SMRs) in the Darlington New Nuclear Project. At UNENE’s R&D Workshop in December 2021, he spoke about the recent selection of the GE Hitachi BWRX-300 as the SMR technology to be deployed at the site, saying it was the result of a thorough and extensive process to determine the best fit for Ontario’s needs and will provide low GHG emission power for the electricity grid and for electrification of other sectors of the economy. Manley also said that ramping up Canada’s nuclear fleet will create a huge human resources need for highly skilled engineers and scientists, and that he sees UNENE playing a key role in meeting the demand. “We’re going to need you and we’re going to need people like you to come into the nuclear sector if we’re going to be successful or else we won’t be able to deploy the nuclear we’re going to need to fight this climate change problem.”
