    HPR4593: Nuclear Reactor Technology - Ep 8 Generation Four Reactors

    2026/03/11
    This show has been flagged as Clean by the host.

    01 Introduction

    This episode is the eighth and final one in an 8 part series on nuclear reactor technology.

    In this episode I will talk about future reactor technologies, particularly what are referred to as "Generation IV" reactors.

    Some of these will be simply additional developments of reactors that have already been discussed in this series, but this will show what technologies are seen as most promising today.

    03 What is Generation IV

    Generation IV International Forum is an international organization whose membership is composed of many of the countries that are researching advanced fission reactors.

    Their goal is to conduct a number of joint research projects to advance the state of the art.

    The members agree to participate in and share research on advanced technologies.

    04 Research Subjects

    05 Lead Fast Reactors (LFR)

    08 Sodium Fast Reactor (SFR)

    10 Gas-Cooled Fast Reactor (GFR)

    13 Very High Temperature Reactor (VHTR)

    16 Molten Salt Reactors (MSR)

    19 Super Critical Water Reactors (SCWR)

    27 Episode Conclusion

    In this episode we looked at the reactor types being studied under an international organization called the "Generation IV International Forum".

    All of these reactor types except for supercritical water reactors are not new and we have looked at them previously.

    Supercritical water reactors themselves represent the natural evolution of water cooled reactors.

    I expect that many of these research projects will not result in commercially successful results. Such is the nature of R&D.

    The supercritical water reactors would on the surface seem to have the most promise in terms of commercial use, as they focus on bringing two very well established technologies together, water cooled reactors and supercritical water.

    However, I'm not an expert in this field, so I'm just making an educated guess on that.

    30 Series Conclusion

    This is the end of the series on nuclear reactor technology.

    Episode 1 covered nuclear basics, including basic terminology and civil versus military nuclear material.

    Episode 2 covered nuclear fuel, including the different types, recycling of spent fuel, uranium and thorium resources, and medical isotopes.

    Episode 3 covered reactor basics, including slow versus fast reactors, moderators, coolants, steam generation, refuelling methods, and the three main commercial reactor types.

    Episode 4 covered the less common reactor types, including types which are no longer used, some historical developmental dead ends, and some types which may possibly be making a come back.

    Episode 5 covered fast reactors, including the different types, some of their history, why they were developed, and why they have so far only seen limited use.

    Episode 6 covered thorium reactors, including what is thorium and how it differs from uranium, why there is interest in thorium, what sorts of reactors can use thorium, and why thorium has not yet seen widespread use.

    Episode 7 covered small modular reactors or SMRs, what the reason is for developing them, what are the different ways they may be used, and where they are currently being built.

    Episode 8 covered "Generator IV" reactors which is a collection of future technologies.

    I hope that this series has been useful and informative on how nuclear reactors work and what the different types of reactors and different types of fuel are.

    I have focused on the past and present without looking very much beyond what is already developed except in this final episode.

    I have focused on the reactors, fuel, and medical isotopes, without much discussion of mining, refining, converting, enrichment, fuel fabrication, or disposal.

    I also haven't talked much about the rest of a functioning power plant, which includes cooling, steam turbines, generators, transformers, control systems, refuelling systems, switch gear, transmission grid connections, grid coordination, and many, many other things.

    And of course there's the entire grid itself, a very complex thing when operated at scale.

    None the less we count on the lights going on when we turn on the light switch while seldom thinking about all the things that go on behind the scenes to make that happen.

    As the recent blackout in Spain shows, that is something that we can't take for granted.

    With plans for "Net Zero" amounting essentially to the further electrification of everything, we need reliable sources of electrical energy to make that happen. Without reliable energy available at the touch of a switch, we don't even have a stone age civilization, let alone a modern one.

    So think about that the next time you turn on the lights or listen to a podcast or do nearly anything else in your daily life.

    This concludes the eighth and final episode of an 8 part series on nuclear reactor technology.

    HPR4592: Happy by shower # 2

    2026/03/10
    This show has been flagged as Clean by the host.

    I also happen to be happy when I see my dogs well. They’re both a little old and have had grave sicknesses. One, the girl, is taking medication because of a problem, maybe on the spine, that interferes with walking, but in general both her and the little white male (who almost died because of stone in the ureter at around the pandemic) are today good, and I’m grateful seeing them in this state. And I suffer when they suffer.

    The hot weather is also more comfortable for them, so, even though we are having
    too much hot
    weeks here in Curitiba [Brazil], it’s a soft, nice, weather.

    Generally I take a cup of coffee on the early morning. Sometimes I give a little run, or go cycling to my duties, without coffee and even without bread. Only then, hours later, I take the coffee and maybe eat something, hours after awake. The exercise, the bath with nothing on the stomach, and, oh, the coffee after (specially the espresso, or american, my current favourite, espresso with hot water), does good, it’s a good feeling outside of the routine.

    I learned to like to share things. I like to share what I judge important. As much as I appreciate doing that, they feel as a burden; an account, or a published content, are like something I’m constantly carrying, that may condemn what I come to be, or may create expectations on others that I can’t fulfil, or are “me in the world”, in a manner that I feel so unsecure. So I feel good, and safe, in erasing everything under my control some time after having created an account or published something.

    I feel well, and it makes me happy, to have a night of sleep in which I don’t wake up more than once. If I wake up early spontaneously, and rested, better yet, good sensation, makes me happy.

    To be true, when I spend the first time on the morning reading the Bible, with prayer, even when I’m not keen on doing that, man, my head and my body end up being marvellous. Martin Luther, the one of the reform, is said to having said: “I have so much to do that I will spend the first three hours praying”.

    A piece of opinion, unasked, if you’re constantly doing something you think it’s too easy, you may not be doing it right, or you’re not doing the right thing. Let’s see what’s wrong and do the right thing.

    One last thing that makes me happy is when my swimming pool is clean. It’s been for years now. As with the other facts, it’s good by itself, yeah, but has more meaning as I had many dirty problems with its water, to the point that the neighbours called sanitary authorities. I don’t want to have any more problems in this area, or in any other area of living, but I know now, and have to guide my heart to feel accordingly to what I know, that any problems that arise are to result in my good and good to other people and other living creatures too. So the difficulties, even the hardest ones, can be faced with peace, because I know the future, and being in a bad state will not help in hiking up and overcoming whatever there is here now or right ahead.

    Our posture, our internal condition in doing something,
    counts much
    together with the external things, visible or invisible, that we do.

    I thank you for listening [reading]. Bye.

    HPR4591: A Bit of Git

    2026/03/09
    This show has been flagged as Clean by the host.

    When attempting to push commits to a remote repository, git rejected
    the push with an error. The branches had diverged! git status

    Result:

    On branch main
    Your branch and 'origin/main' have diverged,
    and have 7 and 1 different commits each, respectively.

    The problem:
    * 79085bb (HEAD -> main) Improve mobile responsiveness for very narrow viewports
    * eec46f5 Improve responsive layout for narrow viewports
    * 79c71eb Fix sync dialog modal instantiation
    * 33fd501 Add markdown rendering to session notes in desktop app
    * 1a119f7 Increase hierarchy panel bottom padding to 9rem in web app
    * c557299 Constrain session notes width with word wrap
    * f2ab785 Add bottom padding to hierarchy navigation panel
    | * 7459345 (origin/main) fix: address bug on Desktop with Sync dialog
    |/
    * c8cc83d Fix routing for Dashboard action after renaming from Index
    After resolving with git rebase there was a new problem. commit
    messages contained

    Generated with [Claude Code](https://claude.com/claude-code)

    Co-Authored-By: Claude Sonnet 4.5 <[email protected]>

    The solution was to use interactive rebase with --exec to amend each commit:
    git rebase -i 7459345 --exec 'git commit --amend -m "$(git log --format=%B -n1 | sed -e "/ Generated with/d" -e "/Co-Authored-By: Claude Sonnet/d" | sed -e :a -e "/^\n*$/{\$d;N;ba" -e "}")"'

    Still the branches differed
    git log --oneline --graph --all -12
    * 4205e86 Improve mobile responsiveness for very narrow viewports
    * a5947ee Improve responsive layout for narrow viewports
    * 012a78f Add markdown rendering to session notes in desktop app
    * d5227d2 Increase hierarchy panel bottom padding to 9rem in web app
