V2.1 of my reactor is now up. it now has a switch on the cooling tower to add water when needed. the next update will be bigger.

@randalserrano
what do the pumps do? I can't fugure out why they are there

did you spark the off switch? if you did, take a look at the holding tank while turning on and off.

is the holding tank the big curved thing with PTCT grid and some water in it?

EDITED: I worked out what the 'cool pump' switch is for, but what about switches for pumps 1 to 6?

those are to the right of the cooling tower. in the building with water.

@randalserrano
I think i get it. I'm guessing that the water from pumps 1 to 6 is meant to go the things labelled 1, 2, 3, etc.
I am also guessing that those things are the reactors?

yes. correct. if you turn the water off, the reactors will heat up. if they heat up too much, they will melt down.

@randalserrano
Literally melt? or fire?

melt. literally.
EDIT
at 1000 degrees thats why that temp meter is there.

Oh no!! I left powder toy on in the background! WITH THE WATER OFF! oops.

Well, at least core number 6 is perfectly intact (pump 6 is on). But the rest: not so much lol

Edited: I would give you a screenshot of it, but it wouldn't let me.

Edited again: core number 1: nothing left at all; core numbers 2 to 5: just the tops; core number 6: Perfectly intact (not that anyone would know: everyone is dead! lol)
