i recently had a VC in a couple new gen reactor companies call me a Negative Nancy. I'm not. I follow the developments. There is one venture, TerraPower that isn't just making another run at fast or pebble bed reactors, generally at a smaller scale. Only TerraPower has the vast risk capital backing needed to try what they are doing, but even they might license a technology to get to market sooner than they can by developing their TWR. It seems like PBRs have the most readily fixable problems, but even those are probably decades away from putting power on the grid. I would bet a number of the venture funded reactors will die of a "liquidity mismatch" with their investors. Some appear to be leaning on developing technologies and patents in anticipation of encountering that problem.
