Even with Danish insolation and weather and tilting the study heavily towards nuclear power by assuming that the nuclear costs are 40% lower than Flamanville 3 and 70% lower than Hinkley Point C while modeling solar as 20% more expensive renewables come out to vastly cheaper when doing system analyses.

This paper is very heavily biased against nuclear power and is only valid for Denmark
It uses 8% discount rate for nuclear vs 5% for VRE
It uses the most expensive nuclear reactor costs instead of Korean and Chinese reactors delivered at 3,500–5,000 USD/kW
80% capacity factor for nuclear is very low and should be over 90% for new reactors.
It's least cost mix intentionally excludes nuclear power which is absurd. Standard practice would let the optimizer choose nuclear's share in a hybrid mix. Sepulveda et al. (MIT, Joule 2018; Nature Energy 2021) using exactly this approach repeatedly find firm low-carbon resources (including nuclear) reduce total system cost under deep decarbonization. https://www.eavor.com/wp-content/uploads/2021/11/The-role-of... "Availability of firm low-carbon resources reduces costs 10%–62% in zero-CO2 cases"
They intentionally ignore inter-annual variability which is where dispatchable nuclear is most needed.
It generalizes based on Denmark's unique situation of having some of the best off-shore wind in the world and access to cheap hydro power and storage in Norway and no domestic nuclear supply chain.

Lund is the creator of EnergyPLAN and cites himself a lot.
This paper just repeats Aalborg group and Breyer's LUT group's anti-nuclear opposition.
