Nuclear Safety in Operating Integrity

What sits here
Plant is operated inside its safe operating envelope, and work is controlled so that barriers are not bypassed, defeated or overloaded. When a barrier is overridden, the override is authorised and controlled. When prevention fails, emergency response mitigates the consequences.
