Advanced small modular reactors, known as SMRs, will probably have many advantages over older technology. But it's not yet known how they will stack up against other sources of electricity.
Nuclear industry players tout small modular reactors as an "inherently safe," cost-effective source of electricity. The reality may be less attractive.
This is a big opportunity for smaller reactors that can be built quickly and cheaply.
Small nuclear reactors are one step closer to powering the UK's future energy requirements.
