    Hey that IS good news!
    Been waiting all my life. Maybe soon..

    Definitely a good thing and NE is a great source of power. The major
    caution is cannot have a Chernobyl happen. If you read what went on and >>> the history is out of science fiction craziness what they did and did

    Chernobyl was a completely different design from the US nukes.

    Several books (I've read two) point to system/design
    failures. In crisis, each person involved acted by the book.
    The book, and the system, were flawed

    For those interested, the video at https://www.youtube.com/watch?v=3dRZQwL-2WTgA
    offers a very understandable account of what went wrong at Chernobyl.

    More interesting to me than the mistakes made is the absolute delicacy
    of managing the control rods to counteract the many competing influences
    on criticality of the reactor. The reactor weighs tens of tons, the
    control rods perhaps a few tons. The criticality can change in
    microseconds. The rods move in tens of seconds.

    There's a very good reason nuclear power is thought of as
    "baseline load only".

    Thanks for reading,
    I would hardly call that a delacate job. It is nothing more than heat feedback. The same as any other fossil fuel power plant and it is a lot easier to control using microadjustments of the absorption rods. I ccould write a program to start from cold, bring it slowly up to temperature and then hold the ideal temperature through various power requirements probably in a day and certainly less than a week.

    I think that people do not understand just how simple a nuclear power plant is.

    They are indeed simple in some ways.

    But once scaled up, there are failure points; plumbing,
    coolant pumps, coolant reservoirs which have both the usual contamination/clogs and now radiation loving bacteria
    biofilm mats, electronics both in sensors and servos, power
    supply to controls and sensors, all the issues of wiring and
    more. As approachable as any power source, but not uniquely
    fail safe.

    Thorium reactors show some promise on paper but the major
    impediment is rarity.

    Engineering advances with iterations, for example your basic
    GM small block V8 engine which is largely as it was in 1955
    but over roughly a hundred million iterations has been
    refined to an astounding level of efficiency and durability
    in the current GM LS.

    over time:

    We just don't build enough nuclear plants to feed that
    failure-improvement loop.

    Operating a nuclear power plant is lot more complex than holding the temperature.
