Publication InformationManuscript Completed: May 2006 Prepared by Division of Fuel, Engineering and Radiological Research AbstractDuring plant operation, the walls of reactor pressure vessels (RPVs) are exposed to neutron
radiation, resulting in localized embrittlement of the vessel steel and weld materials in the core
area. If an embrittled RPV had an existing flaw of critical size and certain severe system
transients were to occur, the flaw could very rapidly propagate through the vessel, resulting in a
through-wall crack and challenging the integrity of the RPV. The severe transients of concern, This report, which describes the technical basis for the probabilistic fracture mechanics model, is one of a series of 21 other documents detailing the results of the NRC study. |
