Considerations for improving the reliability of the off-site power supply for nuclear generating stations

It is argued that improvements in plant distribution system analysis, maintenance procedures, work control, definition of ownership, provision of detailed operational procedures and improved training can reduce loss of offsite power events. These improvements are not simple to implement in many cases, but as maximum grid loads grow and control and protective relaying become more complicated, it is essential that the processes to ensure adequate analysis, training, maintenance, and work control be in place
