Advanced Nuclear Reactors

The cluster focuses on discussions about innovative nuclear reactor designs like Generation IV, small modular reactors (SMRs), microreactors, and floating or portable systems, including their safety features such as meltdown-proof capabilities, historical examples, and barriers to widespread adoption.

Can someone explain to me how this reactor is meltdown proof?

Source? Is this inherent in all nuclear plants, or only in certain designs?

Are they building nuclear reactors to power those?

Can't you just use a Candu reactor for that now?

vivzkestrel Oct 30, 2024 View on HN

what about pocket nuclear reactors? when are we getting them?

Have you heard of generation IV nuclear reactors?https://en.wikipedia.org/wiki/Generation_IV_reactor

You are talking about reactorsI am talking about power plant ; one nuclear power plant has generally multiple reactorsA lot of active nuclear power plant are old and based on old design. This article was written before Fukushima !Many new projects are canceled because nuclear is now too expensive, partly due to the security constraint

Something similar to https://en.wikipedia.org/wiki/Russian_floating_nuclear_power... ?

question, why aren't we building more nuclear power plant like china? isn't gen 4 reactor safer?

Counterpoint: we've been powering ships with microreactors for decades.
