Here the KUN-24AP container ship would be a massive departure with its molten salt reactor. Despite this seemingly odd choice, there are a number of reasons for this, including the inherent safety of an MSR, the ability to refuel continuously without shutting down the reactor, and a high burn-up rate, which means very little waste to be filtered out of the molten salt fuel. The roots for the ship’s reactor would appear to be found in China’s TMSR-LF program, with the TMSR-LF1 reactor having received its operating permit earlier in 2023. This is a fast neutron breeder, meaning that it can breed U-233 from thorium (Th-232) via neutron capture, allowing it to primarily run on much cheaper thorium rather than uranium fuel.

An additional benefit is the fuel and waste from such reactors is useless for nuclear weapons.

so they've mounted some sails on the big cargo ships but all they do is reduce fuel use by 20-30%. if it's even feasible for ships larger than 30% the size of a modern bulk, they gotta be newly built, no retrofitting. rigging does have a bit of automation recently so the question of how much more labor is open, though smaller ships would necessarily mean more labor for the same amount of cargo.

like i endorse it if someone got this going in an mechanized, full-wind power way. it would be dope, but ironically a much larger project than this nuclear boat. which is just changing out the engine that drives the propellor
