> a nuclear powered grid to be vastly more expensive than a renewable grid when looking at total system cost

Yes, nuclear is more expensive. SMRs should help with that, but their expense has never been contested.

But marginal economics aren't everything. Renewable and battery production isn't ramping up fast enough to make that margin available at scale. This doesn't seem capital contrained, either--every major economy is throwing gobs of cash at the problem.

> Every dollar invested in nuclear today prolongs our reliance on fossil fuels. We get enormously more value of the money simply by building renewables

False economy. A dollar not invested into nukes doesn't go into renewables--partly because of the aforementioned scaling problem, it tends to wind up in gas.

We’re spending trillions of dollars of new money on gas infrastructure with decades of life and financial liabilities attached to them because we need the power, have maxed out renewables and are left with a choice: gas or nukes. Opposing nukes isn’t playing for renewables, it’s playing for gas.

SMRs can potentially do something that renewables can’t: they could be placed near the loads in places with no space for renewables and without relying on the grid. Think industrial areas or even cities or towns that are surrounded by other developed land. The grid moves slowly, and electricity prices via existing transmission lines are, in many areas, hilariously inflated for a number of reasons. A hypothetical portable, easy-to-acquire SMR producing power at $100/MWh would not be an amazing deal if a large electric utility bought it, but a $100/MWh would be an amazing price in quite a few markets if a small utility could actually buy at that price and deliver via a small last-mile distribution system.
