Design Basis Flood for Nuclear Power Plants on River Sites

Presents techniques for determining the design basis flood (DBF) to be used for siting nuclear power plants at or near non-tidal reaches of rivers and for the protection of nuclear power plants against floods. Both natural floods and those due to dam failures are discussed.

This guide presents techniques for determining the design basis flood (DBF) to be used for siting nuclear power plants at or near non-tidal reaches of rivers and for the protection of nuclear power plants against floods. Both natural floods and those due to dam failures are discussed. Flooding could have repercussions on safety; consequently the DBF has to be chosen to have a very low probability of exceedance per annum. Two types of methods (probabilistic and deterministic) are discussed.
