The cost of one days electricity on the Australian grid is three times (or 50 times) more than it wa, page-104

The costings can only be relative to current installations... so all the fear mongering can be directed there.

In France they have 58 Nuclear Reactors ..... 58! So we have a precedent in production for decades supplying external markets.

The low cost of French nuclear power generation is indicated by the national energy regulator (CRE) setting the price at which EdF’s electricity is sold to competing distributors. In 2014 the rate is €42/MWh, but CRE proposed an increase to €44 in 2015, €46 in 2016 and €48 in 2017 to allow EdF to recover costs of plant upgrades, which it put at €55 billion to extend all 58 reactor lifetimes by ten years. In November 2014 the government froze the price at €42 to mid-2015. This Arenh re-sale price has represented a long-term floor price for EdF’s power, and is nominally based on the cost of production. The industrial group Uniden said that the proposed 2015 wholesale price of €44/MWh would be €14 higher than Germany’s.
French retail prices, without major effects from feed-in tariffs for wind and solar, remain very low. In 2013 French prices for medium-size industrials were about 90% of EU-27 average, and those for medium-size households (at less than 8 c/kWh) were less than half of EU-27 average.

That is 8 c/kWh unlike in Australia the highest prices in the world.
