Sandia National Labs' MELCOR
Severe Accident modeling code is a fully integrated, engineering-level computer
code that models the progression of severe accidents in light-water reactor
nuclear power plants (NPP). GNP for the Korea Institute for
Nuclear Safety (KINS) has awarded WSC a contract for development and integration
of a MELCOR Severe Accident (SA) Simulation model in the KINS simulator, which
is based on Shin Kori 3&4.
WSC's severe accident (SA) models allow simulation,
in real-time and fast time, of various malfunctions in abnormal/emergency
situations requiring operator actions and/or observance of automatic system
Integrating WSC SA models with the KINS
simulator will allow the KINS technical personnel to run a variety of accident
conditions and scenarios that should help improve the response of the teams
involved and support research in mitigating such situations.
enhancing the SA models, WSC will integrate a powerful 3D tool with the 3KEYMASTER Environment to provide visualization of
SA concepts and scenarios, systems, components, and events, allowing the user
to visualize what previously could not be seen. The high-fidelity SA simulation
models will pass physical characteristics such as temperature, Pressure, Void
Fraction, and Flow to allow a 3D dynamic visualization of those parameters
using a customized color-coded shade. The user will be able to obtain the
parameter value at any location within the 3D object.
The power of 3D
visualization is to be combined with high fidelity SA simulation models to
provide KINS an integrated platform with real time simulator response.
