You can however price this in, and I doubt it accounts for 110$/MW. Furthermore, nuclear energy specifically only runs according to schedule. Reducing or raising output is expensive and slow.
For simplicity, lets use the cost of for every $ that a KG of green hydrogen costs, this mean that the cost per MW will be 30x of that. So if green hydrogen cost $1/KG you the cost in term of MW will be $30.
The current cost of green hydrogen is somewhere between $2 -> $12. That is the production cost. The market price for green hydrogen sits around $4-$20, since there are multiple industries that demands hydrogen.
For 110 to break even the hydrogen need to cost $3.5/kg, and in order to really displace natural gas, it is estimated that it need to reach $1/kg.
Now I noticed that those $150/MW is not a range, so I took a look. Projected nuclear LCOE costs for plants built 2020-2025 places nuclear around $27/MW to $147/MW depending on financing and country (source: OECD Nuclear Energy Agency’s (NEA's) calculation). Russia has the lowest cost and Slovakia or Japan (depending on financing method) has the highest.
So in summery, it can definitively cost more than $110/MW to produce viable green storage solution, especially in northern countries where low duration lithium batteries is not a working solution for long winter periods with low wind production and the sun is only up for a max few hours per day. Nuclear can also be much cheaper depending on where it is built and how it is financed.
EDF has published a paper stating they can scale 80% down and then up again, every day, within 30min.
In practice, they have done something like 20% within an hour. It was early 2019, there was such a crazy wind that they had to reduce nuclear production also (after already reducing coal, gas etc. to the min).
I think what they really can do is somewhere in between.
