Who We Are: Brantley Fusion Systems leads in structural engineering, finite element analysis (FEA), and engineering management consulting, specializing in nuclear fusion innovation through first principles engineering.

What We Do: Our team delivers robust solutions for next-gen energy projects across the U.S. and beyond, using advanced FEA (nonlinear thermal, seismic, strain, bi-linear and multi-linear materials analysis) to design fusion reactor vessels, cores, structures and support systems that thrive in extreme conditions.

Our Expertise: Led by a top FEA expert, we’ve shaped fusion projects like Tri Alpha Energy’s Copernicus and other fusion startup test reactors, building on fission experience (e.g., TVA Watts Bar II, WEC AP1000, FPL/Duke Nuclear fleet, post-Fukushima flex structures across the US) to deliver designs validated by rigorous NRC approval.

Our Services: We offer structural engineering design, analysis, engineering management, field support, regulatory guidance, and project execution—tailored to accelerate fusion breakthroughs and rooted in a first principles approach.

Why Choose Us: Trusted by industry leaders, we provide on-demand, fusion-focused solutions to drive your projects to success.
