Advanced Modular Reactor (AMR) Research, Development and Demonstration Programme: Phase A competition

BEIS is providing up to £2.5 million in innovation funding to support the development and demonstration of High Temperature Gas Reactor (HTGR) technology in the UK.



The AMR RD&D programme aims to demonstrate High Temperature Gas Reactor (HTGR) technology by the early 2030s, in time for any potential commercial AMRs to support net zero by 2050.

This HTGR demonstration, which will be sited in the UK, should be shaped by end-user requirements, and should incentivise private investment in HTGRs by removing technical risk. It should have innovation at the centre of its design, build, and application.

Through a pre-commercial, fully funded Small Business Research Initiative (SBRI), this Phase A competition aims to fund up to 6 Pre-FEED (Front End Engineering Design) studies across 2 key technology lots. These are:

  • Lot 1: Reactor Demonstration (up to 4 Pre-FEED studies will be awarded) for projects developing Advanced Modular HTGR technologies, with up to £500,000 available for each project
  • Lot 2: Fuel Demonstration (up to 2 Pre-FEED studies will be awarded) for projects developing Coated Particle Fuel (CPF) for HTGR technologies, with up to £250,000 available for each project

The AMR RD&D programme is part of the £385 million Advanced Nuclear Fund, and is aligned with the £1 billion Net Zero Innovation Portfolio (NZIP) which aims to accelerate the commercialisation of innovative clean energy technologies and processes through the 2020s and 2030s.

To support Phase A, the Office for Nuclear Regulation (ONR) and the Environment Agency (EA) have been allocated up to £830,000 to continue to build and maintain their capability on advanced nuclear technologies.
