I'd be interested to see the numbers on this.
How much diesel-equivalent fuel could a 1GW nuclear power plant create in one year?
Here's my back of the envelope attempt.
1000MW * 0.9 capacity factor = 900
900 * 24 * 365 = 7,884,000MW
7,884,000 * 0.3 = 2,365,200MW electricity to liquid fuel efficiency[1]
2,365,200MW * 1000 = 2,365,200,000kW
2,365,200,000 / 10 energy content of 1L of diesel being ~10kWh
236,520,000L of diesel per year from a 1GW power plant.
Australia alone uses something like 33,000 megalitres of fuel per year (that's not all diesel, a lot of it would be petrol, but close enough).[2]
So Australia alone would need something like 140 x 1GW nuclear-to-diesel plants.
Did I do something wrong here? That seems like a lot.
This[3] says Australia has electricity generating capacity was 66.5 gigawatts (2017 number), so my 140GW estimate to cover Australia's transportation fuel requirements by electricity-to-diesel seems within the correct order of magnitude.
