    gen 4  plants are better designed and give more output

    A minor (percentage wise) part of our power needs? Yes but not dormant and even that is 20-40 years down the road really

    •  Only 1 nuke is currently under construction (0+ / 0-)

      About two dozen proposed projects have submitted combined construction/operation license applications to the NRC for new nukes.  Some have obtained the license, yet others have suspended their application review after Fukushima.

      But only 1 project is currently under construction -- Watts Bar Unit 2 (Tennessee).  All of the other projects are merely applying for licenses, and planning for future construction.  The cost uncertainty of construction makes all of the projects very risky to ratepayers and bondholders.  I'd be surprised if more than a handful actually get built.

      Regardless of calling these "gen 4 plants", the new proposed projects are the same old designs from 30 years ago: ABWRs, AP1000s, etc.  They still utilize same zirconium clad fuel, which risks hydrogen explosions in case of extreme temperatures from a loss of cooling accident.  This was the fatal flaw at Fukushima... the problem is the zirconium.

        actual gen 4 reactors that can 'fast process' thorium which seems to be something different then what you are talking about

        You know we largely agree? In the long term I'd be surprised if nuclear accounts for even 10% of the nations' power but that's not dormant
