930,277 Lancastrians reject 299 sq km of Offshore Wind in Favour of a Single Sellafield Reactor.

A Sellafield based Nuclear Reactor 
can generate all of the electricity [domestic; commercial; industrial] used by a population of 942,424 people for 60 years.  That's more than what is required for the Cities of Lancaster, Preston and Liverpool.
Population Supplied: 930,277
6 Offshore Wind Farms
Off the North West Coast of England are : 
West of Duddon Sands; Walney; Robin Rigg; Ormonde; Barrow; Burbo Bank.          
4C Offshore

A total of 363 x 3.47 MW [average] turbines occupy 188 sq km, have an Installed Capacity of 1,260 MW, have an Average Lifespan of 22.5 years and cost £3,655 million 
[£2.9 million/MW Installed]

'Homes powered annually': 762,507.
BEIS figure: 3,994 kWh/home per year.
So - Electricity generated per hour: 347,654,447 W
 @594 W/person
Population Supplied: 585,277
To supply 930,277 would:
Require 577 x 3.47 MW Turbines
Occupy an Area of 299 sq km
Have an Installed Capacity of 2,002 MW
Cost £5,806 million
To supply for 60 years, all of this Offshore Wind Farm Capacity has to be built a 2nd Time and then Generate for 2/3 of the life of the 3rd Build - That's a factor of X2.66' !
That would cost: £15,487 million.
[The output from 1,539 x 3.47 MW turbines]
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 620 MW SMR would cost:                    £4,883 million.

Offshore Wind Turbines cost 3.17X more than SMRs !

Sellafield 24/7 Electricity to supply 930,277 Lancastrians and Save 94,153,882 tonne of CO2 Emissions.

In 2016, 338.6 TWh of electricity were generated in the UK

In 2016, the population of the UK was 65,111,143

That means every hour of every day, every man, woman and child in the UK 'used' 594 Watts - that includes the electricity used domestically and by industry, commerce, schools, hospitals - and everything that, 
for each and everyone of us, provides our 
wonderful way of life.
On a site the size of a large supermarket, the GE-Hitachi PRISM Reactor has an installed capacity of 622 MW. It will operate at 90% capacity factor for 60 years

Every hour it will generate 559,800,000 Watts of 24/7, low-carbon electricity.

So it is capable of supplying: 
942,424 people, every year for 60 years !

100 miles of National Grid, serving:
City of Lancaster: Population 138,375
Preston Built Up Area: Population 313,322
City of Liverpool: Population 478,580
Grand Total: 930,277
List of Towns and Cities in Lancashire by Population

With coal disappearing from the electricity generating scene, a conservative estimation of emissions saved would be to consider displacing gas-fired generation:
"...electricity supplied by gas (320 tonnes of carbon dioxide per GWh)..."
P. 15 - Electricity Generation. CO2 Emissions by Fuel Type

From a tiny supermarket-sized site, this single PRISM installation will generate 4,904 GWh of 24/7 electricity and save 1,569,231 t CO2 emissions, every year for 60 years.
