    Former naval reactor operator here. It was clear to me at the time (1982-88) that one could be built that was fully automated. Dual redundancy to SIL 4 safety PLC's can make these micro reactors a single pushbutton operation without a "real" reactor operator present. PLC can be a hell of a lot smarter than the 20 year old kids we have running reactors on every aircraft carrier. I anticipate your funding will be well supported under the new Trump administration. Especially with support of advisors like Elon Musk.

      @OVER-bENGINEERED SIL4 is only necessary in (or intended for) situations that can cause mass casualty events. So trains, nuclear plants, chemical plants, are places you would find such systems. We wouldn't find them in Naval Nuclear because technology in the US Navy is 20-30 years behind industry. Naval Reactors waits far too long for systems to be approved.

    Using AI for control of a nuclear power reactor? As a professional engineer of control systems that worries me. We've been down this road before with fuzzy logic controllers. "you don't have to tune PID loops" they said. True enough.
    But it couldn't tell you when things changed. So the controller would quietly compensate for something that someone needed to know about. Nobody would know about certain wear and tear until the controller simply let go because it couldn't handle the situation any more. The result? Failure due to foreseeable conditions had there been a plain old PID loop controller. Maybe the scientists have their reasons. But for the love of all that is good, please talk to a professional engineer with a couple decades of experience before committing to some shiny concept like AI.

      But this comment implies we continue down the same path as we have been for decades. Worried and afraid to take chances leads to no progression. Also, as if nothing has been learned over the decades and documented and only engineers would have the knowledge needed to move forward. This will cause other countries to progress faster (if they haven't already)
      Now many of these smaller reactors use molten salt, liquid metal or other types of cooling solutions and not light water. Also I don't think anyone stated "nuclear" as your comment stated. There are other minerals to get the same reaction from a reactor such as Thorium etc.
      Just like the steel industry wouldn't adapt and change from open hearth to electrical arc, if we do not accept change we will be left behind. I personally don't believe we've used this technology to the fullest in fear of ____ (insert your fear)
      Current AI requires a database which is programmed by professionals with direct input from other professionals based on the system design required. We are not even close to AI = No humans in the loop and I don't know if it ever will be as the core AI community is well aware of societies fears. AI in 2024/2025 requires human oversight to monitor progress.

      AI is only mentioned in design support. AI can do millions of runs of worse case scenarios and loop back to make a change to the design and run the simulation again. Millions of iterations to optimize the design. For actual reactor operation, simple dual redundancy safety rated PLC's with the right programming and rated to SIL 4 integrity is a no-brainer. I was a 20yo kid running a reactor for a nuclear aircraft carrier. A PLC can certainly handle that task.

      I lived 25 miles downwind of the SONGS nuke plants for 36 years and would be happy to have my city host a SMR tomorrow. We had no problems from SONGS whatsoever, and some friends worked out there jumping into the reactor area and helping change fuel rods. They've had no problems from it to this day, either. Distributed SMRs would end our vulnerability to terrorist attacks on the grid by doing away with the grid altogether(ish).

    Dear nuclear people. From my experience as a nuclear engineer and reactor operator, I can tell you with certainty that these smaller reactors are no more modular than the old big ones. I have worked on the older reactors as well as several of the new modular projects. Videos all over the internet depict modular reactors being transported to remote sites. But this is much the same way we delivered the reactor vessel to Calvert Cliffs in 1969. What the videos fail to show you is the additional 'stuff' you have to build to operate the reactor. Turbine building, reactor building, control building, rad waste building, circulating water system, circ water intake structure, output transformer, switchyard, security building and fencing. And all these systems must be included in your license application. So, your videos are disingenuous. They leave the impression it is just a black box you deliver it and turn it on. You better fix your ad campaign because you're going to lose public support when they find out the truth.

    Micro reactors are great for hard to reach locations, but on the scale of things, i think they are vastly inefficient compared to large power plants. Economies of scale have shown across all industries, the bigger the factory the more efficient the plant. Dont fall into the trap of millions of small reactors that will burn up all the uranium available. After all, Uranium is a rare earth metal..... rare being the key word. Less availability will push up prices and will price out the general public and make everyone who doesnt use fossil fuels, energy poor.

    Fantastic presentation but there's a LOT you left out.
    FIRST - I do support the use of nuclear energy but the pro-nuclear lobby needs to be a lot better at messaging and leaving out issues DOES NOT HELP.
    1) No matter what anyone says there is always the issue of disposal. Here in Australia we have several Uranium mines including Olympic Dam which has around 30% of the worlds reserves. Its principally a copper deposit that's also laced with Gold and Uranium but its underground and is a stable land site. There's no reason why we can use it to store spent fuel. Why the rest of the pro-nuclear people can't or wont suggest disposal sites is pretty poor.
    2) Micro reactors have a basic efficiency issue with neutron flux. Neutron flux (the flow of neutrons through the reactor core) is what keeps the nuclear reaction going. Yes these small reactors can work but because of their scale they are also LESS EFFICIENT because they have a lower neutron flux.
    3) On the subject of efficiency and as an engineer this is a subject that annoys me a lot these days. No matter what anyone wants if you are using steam turbines then the THERMAL EFFICIENCY is limited to about 36% and that is simply dictated by the Laws of thermodynamics as any engineer knows.
    If you go and look at the latest reactors on Wikipedia and look at the thermal energy and electrical output you can find out the EPR 2 (European reactor) gets about 36% and the AP1000 (American reactor) gets about 35%. Interestingly MOST coal fired and other thermal plants get about the same efficiency because they also have to obey the laws of thermodynamics. Its because steam turbines are limited by a thing called Carnot Cycle efficiency Ceff = 1 - Tc/Th where Tc/Th is the temperature ratio over the Carnot Cycle and its not easy to get that Tc/Th less than 0.65. It has been done with high temperature flash boilers with coal. Its also why Gas Turbines are more efficient because they have a Tc/Th ration of about 0.54.
    Overall really good I just wished they'd go into some of the details a bit further.

    Micro modular reactors have only been 5 years away since the later 1940's yet not a single one has ever been built, by any country, anywhere on earth. The fantastic promise of MMNR's has prompted scores of billions of dollars of investment and lots more investment will be coming but the little actual research that all this money gets spent on keeps uncovering more problems that push the eventual commercial availability of MMNR's further down the road. Fact is, what we need WAY more than MMNR's is economical, efficient storage for renewable energy. Producing the energy, whatever the source, isn't the main problem, we have orders of magnitude more cheap, renewable electricity than we could use with quadruple the population currently on the earth, storage and transport is the issue. Sure wish obama had spent all our tax dollars on battery research instead of on flooding the country with existing technology Chinese solar panels. We'd probably have the miracle battery we need by now. Instead, obama pissed away all that money on virtue signaling that he could put his name on during his administration.

      @@justanghozzst8218 No, even if there were no regulators or government hoops to jump through, the economic and physical barriers to implementing commercial micros are WAY too huge to realistically be overcome. Even if the entire reactor construction were no cost, the fuel would have to be 1/10th the price it currently is for micros to even start being economically viable. And while the cost of the fuel could hopefully be reduced some if huge volumes of it started to be made, the cost won't go down to 1/10 of what it currently is.
      Don't forget, the nuclear industry is making HUGE sums of money off of just the promise of micro nukes, why would they bother actually moving forward to what would be an inevitable failure and the end of the investment gravy train?
      The physical barriers, such as, the smaller the fuel quantity, the more radiation escapes into the shielding instead of hitting and reacting with other fuel means an enormous fuel loss compared with larger reactors. All that wasted radiation still has to be paid for and then dealt with, it just doesn't contribute to the economics of the operation.
