okay
i hope i dont repost this idea! cant search in this moment iam online with my phone XD
i forgott the alert for the ractor!
its simple
when the reactor heat goes above 75% (or more, less) redstone = 1 so i could place a redstone torch in my house and when its on i know in a few minutes everything blows up! its just tricky to code this, because redstone can turn off the reactor..
