Yep that's how a tamper works. You can get your nuclear chain reaction going by using it to get your neutron economy to a level where it's critical, and otherwise wouldn't be at the same mass/geometry without the tamper.

Which is also great because if you're generating too many neutrons, you can remove the tamper a bit and then you go below 1 extra neutron per neutron spent again. This combined with how a lot of neutrons are delayed anyway safeguard any reasonable fission plant from a prompt-critical accident, unless it's made by retarded soviets.

If the surrounding material acts as a tamper, it can help the fissile material reach critical mass, so there is more radiation coming out of the remaining space as more of it is covered up. But in this video it is implies that there is a lot of radiation getting out when it's completely covered, which is nonsense, of course.

I feel bad for bald people because there's nothing they could have done to prevent it, but this is cope.

until they find out that without wypeepo, the society they rule regresses to the middle ages, if not further back

we need to crate a cyberspace so we can also shoot task manager (the windows software) in the head 4 times

they get aggressive if they got calves because for some reason they think you want to kill them on sight

twittards when a couple has an age difference of more than 4 nanoseconds

and then they'll flee to wherever the white people went to after the West turned into Shitholistan, and of course the white people will take them in again because they're being ruled by jews who want to destroy them... again

That was when they teased a Diablo game and then it turned out to be the phone game. Obviously it didn't destroy the company, but Diablo isn't doing so hot right now. Making a Diablo game for phones and expecting people to be excited for it got to be one of the most out-of-touch decisions in gaming.
