Numerically Modeling the Unthinkable: When Reactor Core Melt Meets Groundwater
By I. VladO2 - 07 ENVIRONMENTAL ENGINEERING & ARCHAEO-GEOPHYSICS NUMERICALLY MODELING THE UNTHINKABLE: WHEN REACTOR CORE MELT MEETS GROUNDWATER Ioan Vlad Department of Geophysics Stanford University CA 94305-2215 USA Summary Disaster scenarios for severe industrial accidents usually deal with a host of smaller contingencies that can lead to a total-failure maximum-damage event. For every small accident that can lead to total failure there is a plan that ends in the successful management of the events so that the failure either does not develop or it is stopped in an intermediate stage. The large amount of precautions to avoid total failure may make

Popa Petrom Ploiesti Romania Risk Management is a mature discipline with its own processes tools and techniques and with consensus about its main concepts and practices. Nevertheless projects still fail to meet their objectives and businesses are deprived of the benefits despite the theory that risk management should contribute success. Why is risk management failing to live up to its potential? The focus is almost entirely tactical and does not consider strategic

The one-way extrapolation operators are derived from the acoustic wave-equation dispersion relation and are usually defined in a Cartesian coordinate system with a vertical extrapolation axis. Riemannian wavefield extrapolation (RWE) is a
