666,667 East Midlands Population Reject 777 Wind Turbines And Choose 1 Small Modular Reactor [SMR]

A single Rolls - Royce 440 MW Small Modular Reactor has a design life of 60 years and a availability factor of 90%. On average, it will deliver 396,000,000 W of 24/7, low-carbon electricity, every hour of every day for 60 years.
Every hour of every day, each man, woman and child in the UK uses 594 W of electricity - not just for our direct use but 'our content' of the electricity used by industry, commerce, business, schools, hospitals and everything that provides our wonderful way of life. So:
Small Modular Reactors - once in a lifetime opportunity for the UK

Keadby 68 MW Onshore Wind Farm
Keadby - Sustainability Impact Report
Supplying 38,000 homes equates to a continual average supply of 17,325,571 W of intermittent electricity. This will supply all of the electricity to 29,168 people.

To supply 666,667 people would require almost 23 Keadby-sized wind farms - a total of 777 x 2 MW wind turbines at a cost of £2,258 million.

The site size for 777 x 2 MW wind turbines would need to be 205 sq km.

And Finally:
To provide electricity for the 60 year design life of the SMR, after 25 years a 2nd batch of 777 x 2 MW wind turbines would have to be built and then a 3rd batch would have to deliver for 15 years [40% of its lifespan] before intermittent wind power matched the 24/7 nuclear power from an SMR. That's the intermittent output from 
1,865 x 2 MW wind turbines.

So that's 2.4 x £2,258 million:     £5,419 million.

The most expensive form of Pressurised Water Reactor, the the 3,200 MW EPR at Hinkley Point, has a capital cost of £18 Billion + a 'delayed' cost of £7.2 billion for decommissioning and waste handling and storage. That works out at £7,875 million/MW.

At the same rate in £/MW for capital cost, decommissioning, waste handling and storage, a 440 MW SMR would cost:                    £3,465 million.

Onshore Wind Turbines cost 56% more than SMRs !
