  • Per the IAEA report on Chernobyl, page 4:

    The control rods and the safety rods of an RBMK reactor are inserted into the reactor core from above, except for 24 shortened rods which are inserted upwards and which are used for flattening the power distribution. A graphite rod termed a 'displaced is attached to each end of the length of absorber of each rod, except for twelve rods that are used in automatic control. The lower displacer prevents coolant water from entering the space vacated as the rod is withdrawn, thus augmenting the reactivity worth of the rod. The graphite displacer of each rod of all RBMK reactors was, at the time of the accident, connected to its rod via a ‘telescope’, with a water filled space of 1.25 m separating the displacer and the absorbing rod (see Fig. 1). The dimensions of rod and displacer were such that when the rod was fully extracted the displacer sat centrally within the fuelled region of the core with 1.25 m of water at either end. On receipt of a scram signal causing a fully withdrawn rod to fall, the displacement of water from the lower part of the channel as the rod moved down- wards from its upper limit stop position caused a local insertion of positive reactivity in the lower part of the core. The magnitude of this ‘positive scram’ effect depended on the spatial distribution of the power density and the operating regime of the reactor.




  • Philosophically, yes. One is created with intent, one is created to mimic intent. Human made works can challenge norms and explore entirely new ways of thinking about a subject. AI content is essentially trying to take everything relevant to a given prompt, blend it together, and give you something that meets your expectations.

    Now as far as is it practically the same, that’s where things are going to start getting sticky. If an AI makes a piece of art that resonates with people the same way that a human created piece of art does, those feelings are just as genuine. There is no practical difference. We’re seeing that right now with AI generated music. Just this week an AI country song hit #1 on billboard. The people that enjoy that song enjoy it regardless of how it was made. Personally, I think that country is kind of a low hanging fruit since it has effectively been following the same formula for a couple of decades, but it’s a great proof of concept.
