But with low power output and extra drain on system, water didn’t actually reach reactor. 3 Automatic safety devices that shut down the reactor when water and steam levels fall below normal and turbine stops were shut off because engineers didn’t want systems to “spoil” experiment. Radiation shields Radiation shields 2 Almost all control rods were removed from the core during experiment. 1 Emergency cooling system was turned off to conduct an experiment.
