-- The Goods
while run == true do

-- Check if Reactor is Formed
 if reactor.mbIsAssembled() == false then
  term.clear()
  term.setCursorPos(1,1)
  print("Reactor not formed")
  sleep(1)
 else

-- Turn Reactor On if Off
 if reactor.getActive() ~= "true" then
  reactor.setActive(true)
 end

-- Figure out Energy stored as a %
 storedEnergy = reactor.getEnergyStored()
 percentFull = math.floor(storedEnergy / maxEnergy * 100)

-- Make sure we are not going over 100 or under 0
 if percentFull >= 100 then percentFull = 100 end
 if percentFull <= 0   then percentFull = 0   end

-- Control the Control Rods
 reactor.setAllControlRodLevels(percentFull)

-- Output Information
 term.clear()
 term.setCursorPos(1,1)
 print("RF:", storedEnergy )
 print("Rod % ", percentFull)

-- Wait to run again
 sleep(1)

-- End the Loop
