I think you said it: it's a non-event. It's the reactor reactor-ing within the design basis. But, I think "single rod-drop" will not shut down a reactor. That's a crazy amount of rod-worth. My opinion is that reactor safe-shutdown margin entails "single rod-stuck" scram to be feasible.
> But, I think "single rod-drop" will not shut down a reactor
Why do you think that? When rods are used to control the reaction rate I thought it was by raising and lowering them small amounts usually.
Being able to have a single fully inserted rod stop things would certainly make it more likely dropping rods into the core would stop an even than if you needed (say) all 3 to be fully inserted.
3x the chance of successfully stopping a serious problem, 1/3rd the chance of a blockage prevent the emergency shutdown.
Why don't you just look it up instead of actively arguing an assumption?
This reactor type has 73 assemblies of 5 rods each.
Nuclear safety regulations require that the control rod system must be powerful enough to bring the reactor completely subcritical with all Control Element Assemblies (CEAs) inserted minus one assembly stuck in the fully withdrawn position.
One assembly (or 3) inserted would not bring the reactor subcritical.
I'm already getting downvoted to oblivion for my gp comment, but whatever: what I was trying to convey based on my limited exposure is that a single rod will have a zone restricted shadow or local effect and multiple uniformly distributed rod banks are therefore needed for a an effective control or emergency shutoff. Additionally, on the flip side, I feel a single rod capable of shutoff will insert excessive positive reactivity in case of an ejection (could be a local steam overpressure, idk, don't hunt me down with hounds).
I don't think optical flats operate based on moiré gratings. The former is an interference/diffraction effect while the latter, is you underpinned earlier, is a sort of spatial heterodyning effect. For instance, you can generate moiré rulings (which effectively an optical illusion) with two angularly misaligned combs, but the comb spacing is order of magnitude larger than optical wavelengths, leading one to conclude it's not a wave interference phenomenon.
I need some help if you happen know your way around flybacks? I have a grime encrusted flyback transformer harvested from a crt set which I would like to hack around with, iff I had some inkling of the internal wiring of the coils, rectifiers etc. All it says is "FOK14A001 REV.0 ANYON T11520VO" and web searches refuse to surface an exact schematic; even though a lot of general information is available. But piecing together a schematic for this specific model is proving a drag from these nebulous floaters.
Well put. It's also eye-opening to watch some exceptionally lucky/gifted individuals exude an unmistakable air of deep contentment that only comes from being "time-rich" i.e. possessing complete command of your time. They get to strictly curate the projects and people around which their livelihood revolves. They can't stop gushing about it. It's like even they cannot believe that they are forming lifelong friendships and having meaningful experiences AT work; b/c everyone had told'em that life exists 'outside of work'.
Of course, that's a ride inaccessible to rest of us plebs, but it's nonetheless insightful to see what that ticket buys.
