Dear Colleagues,
Over the last 5 years, new calculation techniques, such as BDD, have been extensively studied in nuclear PSA. The concern of these studies has been to end the use of approximations: numerical approximations for which we do not know the error factors, and modeling approximations which leave out perhaps critical elements of the actual plant.
From all these investigations, some alarming issues related to large nuclear PSA models have been raised, which we feel need to be addressed as we put new calculation engines or next generation user interfaces into place:
