Long-term strategy calls for up to 10 new reactors in Canada
Canada has launched a Nuclear Energy Strategy, a long-term vision of its nuclear power potential that includes plans to deploy up to 10 new large-scale reactors in the country by 2040.
The June 22 announcement, along with ongoing projects at Darlington and Bruce Power, further confirm Canada's ambitions to expand its nuclear power presence not just domestically but also abroad. Four pillars stand at the heart of the country’s Nuclear Energy Strategy: new nuclear builds in Canada, maintaining its status as a top nuclear supplier and exporter, expanding uranium production, and continuing nuclear fission and fusion innovations.

In this paper, we describe the implementation, verification, and numerical validation of Generalized Perturbation Theory (GPT) capabilities in the TRIPOLI4® Monte Carlo code. The GPT is applied to reaction rate ratios (linear forms) and effective kinetics parameters (bilinear forms). For these latter, we focus in particular on the effective neutron generation time Λeff, the effective prompt lifetime ℓeff, and the effective delayed neutron fraction βeff. Verification is achieved comparing the results obtained using TRIPOLI-4® to benchmarks where analytical solutions are available. Numerical validation is performed with respect to independent Monte Carlo calculations using the SCALE 6.2.4 and SERPENT 2.2 codes, to published results, and to direct perturbations. Finally, a comparison with respect to the APOLLO3® deterministic code is performed for the EPICURE experimental configuration of the water-moderated EOLE reactor core, formerly operated at CEA.
