Onset of computer-based systems

Technical specifications, which define the operational limits and conditions within which a nuclear power plant must be kept, have dramatically increased in volume and complexity to the extent that computerized systems have been developed for their storage and retrieval. The state of the art systems encompass a number of capabilities including: tracking and scheduling routine surveillance, listing test procedures, keeping records of test history, tracking operability of components and systems, and comparing with equipment required by the LCO's (limiting condition for operation) and notification when an LCO is entered, its description, and the status of time deadlines. Other technical capabilities, advantages in speed applications to risk assessment, and accuracy, and expectations for implementation are discussed
