Accross all active nuclear power stations in 2040, what will be the least spent per MWe (Megawatt Electrical)?
The fifth planned Rolls-Royce SMR is expected to cost £1.8bn (~$2.2bn) to generate 470MWe - at a cost of £3.8mm (~$4.6mm) per MWe.
Price of a MWe is considered in the context of price per plant, meaning extensions to existing plants will affect the plant's total Price per MWe, not be considered separately. Similarly, re-activating existing inactive plants will not be considered for Price per MWe.

1,000evidence. at the end of 2022, Hinkley Point C is projected to cost over £30bn (https://manifold.markets/JoeReeve/will-hinkley-point-c-be-completed-f) to eventually produce 3200 mWE. £30bn -> $38.69*1000*1000*1000/3200 = 12mn
There will be a follow on from Hinkley Point, hopefully copying it and being done cheaper. Rule of thumb is a disaster somewhere in the world every two decades doubles the cost of all reactors currently being built. The SMR are supposed to be cheaper, but are a research project.
