Mechanisms of Magnetite Deposition in Pressurized Boiling and Non-boiling Water

📖 The Scoop

The melprog computer code is being developed to provide detailed, best-estimate, coupled analyses of all the major phenomena involved in the course of a severe accident progression. the initial version of this code, melprog-pwr/modo, is described in this report. the purpose of melprog is to provide at any time during an accident sequence a description of (1) the state of the reactor core and surrounding in-vessel environment, and (2) the disposition of core materials (in particular, fission products) contained within the reactor coolant system boundary. melprog is coupled to the trac-pf1 rcs thermal-hydraulics code to provide an integrated analysis of the behavior of core, vessel, and reactor coolant system during severe accidents. melprog treats core degradation and loss of geometry,debris formation, core melting, attack on supporting structures, slumping, melt/water interactions and vessel failure. the key element in melprog is the use of detailed modeling for the entire damage progression and failure sequence. emphasis is also placed on the rates of hydrogen, steam and fission product formation, and transport to containment during damage progression.
