AP1000 SBO information

The nuclear term SBO has begun to get into the usage of some of the general public as a result both of the Fukushima Daiichi accident and as the result of a few storms in the United States in the last two years that resulted in brief SBO conditions (but of course in the US, the diesels started, ran and kept running in every instance.) SBO stands for "Station Black Out" and refers to a total loss of all AC power being supplied to the nuclear power plant site from outside the plant.

Westinghouse has today released a very excellent presentation on its new AP1000 nuclear plant's abilities in an SBO situation. This is important as AP1000 plants are actually under construction right now not only in the United States but in other countries. Advocates of reactor safety (and aren't we all?) and those interested in the overall SBO mitigation strategy will find the link below of great interest.

  1. The presentation was pretty neat, but the whole affair seemed a bit too complicated... Some sort of external power or pump is needed within 72 hours, even if everything goes to plan. There was not enough information to explain how the tanks and pipelines and valves needed to supply the water are protected, in case there's a flood, fire, earthquake, explosion or other calamity.
