Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

For renewables, Construction, Maintenance and Demolition cost more

This is less true as time goes on. CCGT and coal has substantial overlap with all-in cost of firmed PV and onshore wind just in terms of capex and FOM. Nuclear O&M overlaps with all-in cost of wind or PV (although not the latter in sweden).

SMRs (most of the proposals to reduce cost) are also substantially less efficient than full sized reactors and the high grade Uranium or Uranium in countries you can pollute without consequence is mostly tapped out so prices are increasing (currently about $3/MWh for full scale or $6/MWh for an inefficient small reactor). By the time an SMR finally comes online, just the raw uranium will cost as much as renewables, let alone the rest of VOM (which is still a minority of O&M which is far, far less than Capex).

Anyone suggesting new nuclear should be regarded as either someone lying to maintain a nuclear weapons program, a scammer, or a russian agent trying to sell dependence on rosatom.

The first is potentially defensible, but they could also not lie instead.
