reactor help please

I need help my friend and I have a server we have a reactor but we don't want it to blow up the lobby were it is as a centre piece,
so we need to stop it if it reaches 8500 and turn it of for 2 hours then turn it back on (if possible, we would like a status output on a monitor including temp, power output per tick, how longs left before it shut-down and turns on) but i have no idea what I am doing please help.

well… What you need is the sensors peripheral. Once you have that it can do all that.

were using tekkit

Tekkit just updated to include the CCsensors. You will have to update to get them. New version is 3.1.2. And yes, it is available for servers.
