Unlocking Advanced Modular Reactors in the UK

What are Advanced Modular Reactors (AMRs) and why could they be an important contributor to the UK’s clean energy transition? This guide explores the barriers currently slowing deployment and outlines a potential enabling framework that could unlock investment and accelerate first-of-a-kind AMR projects.

Advanced Modular Reactors are a new generation of modular nuclear technology. They are designed to be quicker and cheaper to build than traditional power stations, while also being more flexible in how they can be utilised.

With a real potential to become part of the UK’s clean energy mix, AMRs offer a transformative opportunity to deliver clean, flexible and cost-effective energy but only if systematic barriers to entry are addressed, that ensure progress around deploying this new technology on first-of-a-kind projects isn’t deterred.

The UK’s energy needs are intensifying. AMRs could play a pivotal role in addressing this, but without targeted intervention, the UK may miss a critical window to establish leadership in this emerging sector.

This guide explores the steps needed to overcome barriers to AMR deployment and outlines an enabling framework to unlock and accelerate projects. With the right conditions in place, AMRs could attract private investment, grow the supply chain, create skilled jobs, and support the UK’s energy and climate objectives.
