| event text = Feed tube level sensor was found to be in a state such that it has failed as an IROFS [Item Relied On For Safety] for a fire accident sequence leading to the loss of a criticality control. Another IROFS is in place and the accident sequence continues to meet performance requirements. Less than a safe mass was always maintained. This event is being reported because only one item relied on for safety, as documented in the Integrated Safety Analysis summary, remains available and reliable to prevent a nuclear criticality accident, and has been in this state for greater than eight hours. | | event text = Feed tube level sensor was found to be in a state such that it has failed as an IROFS [Item Relied On For Safety] for a fire accident sequence leading to the loss of a criticality control.
