A visitor stands behind A Desk (reactor control engineer’s position) in the Unit 2 control room, ChNPP. On the panel behind him is a reactor core cartogram with lamps for each of the ~1700 fuel channels (white) and ~300 other channels for control rods and instrumentation. The lamps were used to indicate various parameters or activities in the individual channels. On the right is another cartogram with servoindicators displaying the position of control and protection rods in the reactor.
