The British government has asked its nuclear regulator to start the process for approving Rolls-Royce's planned small- scale modular nuclear reactor, which policymakers hope will help cut dependence on fossil fuels and lower carbon emissions. From a report: Britain last year backed a $546 million funding round at the company to develop the country's first small modular nuclear reactor (SMR), part of its drive to reach net zero carbon emissions and promote new technology with export potential. Energy minister Kwasi Kwarteng has also said new nuclear projects will play an important part in Britain's efforts to reduce its reliance on expensive gas, which hit fresh record high prices on Monday amid the crisis in Ukraine. SMRs can be made in factories, with parts small enough to be transported on trucks and barges and assembled more quickly and cheaply than large-scale reactors. Each mini plant can power around one million homes and Rolls-Royce has forecast the SMR business could create up to 40,000 jobs based on British and export demand.

The British government has asked its nuclear regulator to start the process for
approving Rolls-Royce's planned small- scale modular nuclear reactor, which policymakers hope will help cut dependence on fossil fuels and lower carbon emissions.

There are more details on the design itself here: https://en.wikipedia.org/wiki/List_of_small_modular_reactor_designs#Rolls-Royce_SMR

"500 day construction"
"10 acres (4 ha) site"
"The target cost is 1.8 billion for the fifth unit built"

So not all that small.

Even the truely small ones can still get nasty: https://en.wikipedia.org/wiki/SL-1

I recently watched on TV a documentary detailing the construction
of a full-size reactor in the UK, called "How to Build a Nuclear
Reactor". However as the pandemic caused lots of delays and
probably prevented the film crew from going on site over that time,
it turned out to be more like "How to Build the Foundations for a
Nuclear Reactor", which wasn't quite what I had in mind.

Here in Argentina we had the CAREM modular design. The problem is the
scale. In the long run, big power centrals are moneywise more efficient
than the midget reactors. But the small power centrals they are useful on
faw awar locations off the main national interconnecter power grid.
