The agreement establishes a cooperative framework for Aecon and Fermi Energia to work together during the SMR development phase as the exclusive provider to develop a qualified domestic nuclear capability, modeled after the Canadian experience, to benefit the BWRX-300 deployment in Estonia.
“We are proud to partner with Fermi Energia as Estonia advances its SMR program in support of the energy transition. Aecon’s experience working on the G7’s first BWRX-300 in Canada gives us the unique position to bring our strong nuclear expertise and technical solutions to one of the most critical aspects of this new build program, including advanced manufacturing, automation processes, lessons learned and best practices,” said Aaron Jonhson, Senior Vice President, Nuclear.
During the agreement’s three-year term, the parties will strategize, plan, and evaluate paths forward for the deployment of the BWRX-300 in Estonia. Aecon and Fermi Energia will work together on a pre-construction schedule and cost planning, and the development of a capable reactor building deployment team, in collaboration with local and international partners.
“This agreement builds on Aecon’s proven experience and gives Estonia access to the world’s most advanced SMR construction expertise. It is a significant step forward towards our goal of delivering safe, reliable, and carbon-free nuclear energy for Estonia’s future,” says Kalev Kallemets, CEO, Fermi Energia.
