> I’m particularly interested in how they plan to finance reactors in a grid dominated by solar.

Solar is 15% - a lot but not yet dominated. Solar works at day and demand is also highest during the day so solar should not be an enemy of nuclear.

It is actually an enemy of nuclear, economically. Solar is so cheap, it will naturally grow until it satisfies 100% of the daytime load. This pushes nuclear off the grid during the day - it’s power costs too much. But nukes need to be running and selling at 100% 24/7 to have any chance of breaking even.

This is what the OP means - they make no economic sense on most modern grids.

Related: Wind and solar generated more power than fossil fuels in the EU for the first time in 2025 - https://ember-energy.org/latest-updates/wind-and-solar-gener... - January 22nd, 2026 > Wind and solar overtaking fossil fuels in 2025 can be largely attributed to a staggering rise in solar power. Solar grew by more than a fifth (+20.1%) for the fourth year running. It generated a record 13% of EU power in 2025, above both coal and hydro. This trend was widespread: all EU countries saw growth in solar generation compared to the year before, amid a huge expansion in EU solar installations. Solar provided more than a fifth of electricity in Hungary, Cyprus, Greece, Spain and the Netherlands. Renewables provided nearly half of EU power (48%) as unusual weather conditions caused hydro generation to fall by 12% and wind by 2%, but boosted solar generation. Wind remained the second largest EU electricity source at 17% of EU power, generating more than gas. Signs of a structural shift are clear across the EU, as wind and solar generated more electricity than all fossil sources in 14 of the 27 EU countries in 2025. Over the past five years, wind and solar have experienced massive growth (from 20% in 2020 to 30% in 2025). Fossil fuels have fallen from 37% to 29% in the same period, while hydro and nuclear remained stable or slightly declined. https://ourworldindata.org/grapher/installed-solar-pv-capaci...
