Considerations on Nuclear Data Link Implementation in Relation to the Technical Support Center, Emergency Operations Facility and Safety Parameter Display System

摘要

Upon the occurrence of a significant event at a nuclear plant, both the Nuclear Regulatory Commission and the licensee must carry out certain roles to mitigate possible consequences. To accomplish their respective roles effectively, both require timely data from the plant instrumentation systems. The relationship of the NRC-oriented Nuclear Data Link to the individual licensee-oriented Technical Support Centers, Emergency Operations Facilities, and Safety Parameter Display Systems have been examined with regard to implementaton of data acquisition, communication, and display requirements. The possible use of a common data acquisition processor for all four systems is discussed, along with technical considerations important in the implementation of such an approach. A common data acquisition system is not recommended but could be successfully implemented if tight control is exercised. Some of the anticipated difficulties in developing standardized data display are outlined. Duplication at the NRC Operations Center of those displays available at the reactor sites will be extremely difficult unless industry-wide standardization of display is implemented.
