ComputerCraft BigReactor (Active) automatic throttling

-- Title: ComputerCraft BigReactor automatic throttling software for Active reactors.
-- Author: MyrddinE
--
-- Throttles the reactor based on the level of hot fluid. Because the hot fluid buffer
-- is small compared to the generation speed, it updates several times a second to
-- maintain the proper temperature.

-- Update this to match your reactor's steam volume.
maxSteam = 9800

-- Set this to the side your monitor is on, or blank for no monitor. If the monitor is
-- connected via a wired modem, set this to the full name of the monitor.
monitor = ''
-- monitor = 'right'

-- Stick the computer right on the port. If the reactor is attached via a wired modem,
-- change the wrap to the full name of the Reactor.
reactor = peripheral.wrap('back')

-- Sets the monitor to a wrapped peripheral if you have one.
if #monitor > 0 then
  monitor = peripheral.wrap(monitor)
  width,height = monitor.getSize()
  monitor.setCursorPos(1,height)
else
  monitor = false
end

-- Run forever.
while true do
  -- The important part of the loop is just three lines, very simple.
  steam = reactor.getHotFluidAmount()
  rod = math.ceil(100*steam/maxSteam)
  reactor.setAllControlRodLevels(rod)

  -- Everything below just drives a scrolling monitor display.
  if monitor then
    temp = math.floor(reactor.getCasingTemperature()).."C"
    monitor.scroll(2)
    monitor.setCursorPos(1,height)
    monitor.write(rod.."%")
    monitor.scroll(1)
    monitor.setCursorPos(1+width-#temp,height)
    monitor.write(temp)
  end

  -- Sleep for a moment.
  sleep(.2)
