A METHOD OF CONTROLLING A NUCLEAR REACTOR OF THE TYPE COMPRISING A CORE STRUCTURE CONTAINING DISCRETE BODIES OF FISSILE MATERIAL COMPRISING THE STEPS OF INTRODUCING A SERIES OF BODIES OF NON-FISSILE NEUTRON ABSORBING MATERIAL INTO THE CORE STRUCTURE OF THE REACTOR SAID BODIES OF NON-FISSILE NEUTRON ABSORBING MATERIAL BEING INTRODUCED INTO THE REACTOR CORE STRUCTURE IN SEQUENCE ALONG A LINE PASSING THROUGH THE NUCLEAR REACTOR CORE STRUCTURE THE SERIES OF BODIES INCREASING IN NEUTRON ABSORBING CAPACITY FROM ONE BODY TO THE NEXT IN THE SERIES BEGINNING WITH A MINIMUM CAPACITY AT THE BODY WHICH IS FIRST INSERTED INTO THE NUCLEAR REACTOR CORE STRUCTURE AND ENDING AT A MAXIMUM CAPACITY AT THE BODY WHICH IS LAST INTRODUCED INTO THE REACTOR CORE STRUCTURE, THE NUCLEAR REACTOR BEING CONTROLLED DURING OPERATION BY MOVEMENT OF THE SERIES OF BODIES AS A WHOLE INTO AND OUT OF THE REACTOR CORE STRUCTURE SO THAT THE NUMBER OF THE SERIES OF BODIES CONTAINED WHOLLY OR PARTIALLY BY THE REACTOR CORE STRUCTURE IS VARIED.
