In this episode of Decouple we deep dive the European Pressurised Reactor and what its troubled construction history reveals about the real constraints on nuclear build out in the modern West. The conversation traces how a design intended to satisfy every regulator through a design philosophy of extreme redundancy and conservative safety margins instead exposed the limits of Western construction capacity, supply chain readiness, and project management culture.

The episode also places the EPR in context alongside other large reactor designs, including AP1000 and APR 1400, highlighting how different philosophies around active redundancy, passive safety, modularity, and operational flexibility shape construction risk and cost. We explore why Germany and Korea were able to execute reactors with highly redundant active safety systems successfully when industrial capacity was warm, and why the EPR pushed that same philosophy beyond the point of diminishing returns.

Why have we built nuclear ships before, proven they can operate, and still not made them commonplace?

Nick Touran breaks down the history of maritime nuclear power, from the Nuclear Ship Savannah and Otto Hahn to Japan’s Mutsu and Russia’s Sevmorput, then pivots to floating nuclear power concepts such as the MH 1A Sturgis and the Offshore Power Systems program. We explore what worked, what failed, and what keeps blocking adoption, including port access rules, indemnity and international agreements, staffing costs, containerization economics, shielding and public reaction, and the unique operational demands of running reactors at sea.

In this episode of Decouple, Dr. Jeff Waksman, Principal Deputy Assistant Secretary of the Army for Installations, Energy and Environment, explains how the U.S. Army is making a second attempt at making microreactors great again. The discussion situates the Janus microreactor program in the long history of the Army Nuclear Power Program and Project Pele, highlighting why earlier small reactor deployments failed to compete with diesel and grid power even in extreme environments, and why Janus represents a fundamentally different approach.

Janus is best understood as an attempt to apply the Commercial Orbital Transportation Services model to nuclear energy, using milestone-based funding, hard downselects, and vendor replaceability to subsidize learning rather than electricity sales. The conversation explores the severe economic constraints facing one to ten megawatt reactors, the limits of the SpaceX analogy, and the unglamorous but decisive challenges of fuel logistics, waste removal, and slow nuclear learning cycles that will ultimately determine whether microreactors can ever move beyond demonstration and into durable military let alone commercial service.
