I'm just gonna stay away even if there aren't people with guns guarding it ready to shoot on sight. If some control mechanism fails, that water gonna get blown away, boil me whole, or have some other spectacularly bad circumstance that wouldn't be healthy to be exposed to.
Reminds me of a show where they focuses on a host visiting sites where they were doing heavy lifts with cranes. One was a turbine replacement at a nuclear plant. The host had a few conversations with the armed security guards present. About half way through the episode he made a comment to one about realizing they were there to protect the reactor from him and his filming crew.
The point of the pool is to shield radiation so it makes sense that the pool is deep enough to attenuate the radiation to safe levels plus a factor of safety (1.5, 2.0, 2.5, whatever) so it makes sense that the top layer is fine. If it wasn't fine the pool is underspec'd.
depends if you're designing for there to be 2x more radiation than expected or half the water will be missing. Nuc reactor probably designed for both to happen simultaneously
This was a question to XKCD's Randal Monroe's What If? Water is used in these to block radiation, so as long as you don't dive and hug the casks, you're good. https://what-if.xkcd.com/29/ You would be a bit better since water blocks normal background radiation as well.
for anyone who didn't click that link and read it (which I highly recommend you do): the piece at the end of the image above, about being shot before you get to the water is a direct quote from the end of that piece
they want to keep the water as clean as possible, so no they dont even let people get close to the water during tours. radiation has nothing to do with it, its more that a piece of debris getting caught in a pump or valve will cause tens of millions dollars worth of damage/downtime.
Fun fact you may already know: those particles are traveling faster than the speed of light (the speed of light *in water*, not in a vacuum - can't get faster than that)
Let me clear it up. Speed of light in a vacuum - the fastest. Light zipping through water - slower than zipping through vacuum. Particles zipping through water faster than light in water but slower than light in vacuum = Cherenkov Radiation.
That pool is spent fuel cooling, not a reactor. It is not blue form Cherenkov radiation. It is blue because that is the natural color of water and that becomes more obvious when there is a lot of it, and from ambient lighting.
True: That pool is spent fuel cooling, not a reactor. But it IS blue from Cherenkov radiation. The effect is strongest immediately after offloading recently irradiated fuel, but persists for years.
The energy of cherenkov radiation is approximately proportional to wavelength, which is why it appears such brilliant blue (the upper limit of perception). It also dissipates with distance. So it wouldn't appear either as aquamarine, nor uniform through the pool. Here's an example where both are present, and you can see quite a difference in both color and uniformity.
It's such an extremely light shade of blue, combined with such a high degree of translucency, that significant quantities are required before the color becomes visible.
Dunnu, sounds like radiation is microdosing kinetic energy. Vault-Tec suggests building up a tolerance to bullets by exposing yourself to radiation first!
The blue hue is mostly the tiles reflection, but the shine is sherenkov radiation. Google it, pretty interesting if you are into math. Wont kill you, butni wouldnt deep dive in one of these pools as your impurities and normal metabolic juice will get radioactive and kill you
Yeah, I already knew a thing or two about Cherenkov radiation. (...Well, in fact exactly two. It's blue, and it's caused by particles traveling faster than the speed of light in water, which sounds super cool tbh.)
Crazily, particle accelerators are such small calibre that they can shoot through you without harming you (much). Turns out that when tiny particles decelerate the amount of energy they lose is inversely proportional to their velocity. That means they dump almost all their energy in the place where they finally stop. If the particles are so high energy that they make it all the way through the target, they’ll barely deposit any energy at all. There was a Russian scientist who managed to 1/
Get blasted with a proton beam to the head. The total ionising radiation dose was so high that instead of being treated, he was observed to learn about how death from radiation sickness occurs. Instead of dying though, he recovered and completed his PhD.
Also a good reminder that caliber tells you basically nothing about how a firearm will perform, which is how you know all the idiots harping about the new M7 Spear being "Terrible" because it fires a 6.8mm round instead of a 5.56 NATO are idiots who have no idea what they're saying
If you have proportional barrel length and propellent load and the same propellant and projectile shape, guns from the same era should have a kinetic energy proportional to the cube of the barrel width/projectile width. That is a lot of ifs.
because the 7.62 NATO round was infamously uncontrollable in full auto and was unreliable against unarmored targets, it went so fast it just punched through them with minimal stopping power. It's why the 5.56 was designed, it's built from they ground up to kill civilians and unarmored combatants. The 6.8 FURY round is designed to defeat body armor at extreme ranges without being uncontrollable the way the 7.62 is
Saying it was designed to kill civilians is a bit loaded, given that soldiers weren't wearing armor at the time. It was designed to kill the military threat it was facing, which from armies large and small, was humans sans armor. Being optimized to kill civilians is coincidental. That is, unless you can source the creator saying he did it on purpose. Otherwise, it was designed to eliminate the military that of the time: guys in shirts.

Alternatively, the guards are ready to shoot you for swimming in the forbidden pool, but the guard captain needs co-operation from The Ring Bearer.

You could put a fish in the pool and as it swam down it would die if stayed near the surface it would survive

The guards fill you with enough lead to handle the radiation so you're fine either way.

2.0x more what? 2x more water, or 2x more radiation shielding (i.e. about 3 inches more water since it halves every 3 inches)?

My question is what is the temperature of the spent fuel pool? I mean depending on the waters temperature the radiation may be a moot point.

Cherenkov Radiation itself is not deadly... but whatever is causing it is.
Dudeeronomy
The fall doesn’t kill you, it’s the sudden stop at the end.

this is accurate, but this is also not Cerenkov blue, or even glowing. Pretty sure it's just the pool's water and the color of the walls.

the particles are moving faster than light does in water.

Let me clear it up. Speed of light in a vacuum - the fastest. Light zipping through water - slower than zipping through vacuum. Particles zipping through water faster than light in water but slower than light in vacuum = Cherenkov Radiation.

It is clear with a very faint blue dye. I'm not sure it would be visible in a pool. More like an ocean.
