A COMPUTER CODE FOR FIRE PROTECTION AND RISK ANALYSIS OF NUCLEAR PLANTS.

THE PROPOSED RESEARCH IS TO ADVANCE THE STATE-OF-THE-ART OF DETERMINISTIC RISK ANALYSIS AND FIRE PROTECTION METHODOLOGY OF NUCLEAR POWER PLANTS. A COMPUTER CODE, BASED ON THE USE OF A FIELD (DISCRETIZATION) MODELING TECHNIQUE, WILL BE DEVELOPED THAT HAS SUFFICIENT FLEXIBILITY FOR ACCURATE/REALISTIC REPRESENTATIONS OF GEOMETRY, VENTILATION AND OTHER CONDITIONS PRESENT IN CABLE ROOMS AND CONTROL ROOMS, AND OTHER ENCLOSURES IN NUCLEAR POWER PLANTS. THE COMPUTER CODE WILL BE CAPABLE OF THREE-DIMENSIONAL, TRANSIENT, TURBULENT FLOW AND HEAT TRANSFER CALCULATIONS WITH CHEMICAL REACTION AND RADIATION. THE CODE WILL HAVE A MODULAR STRUCTURE, SPECIFICALLY DESIGNED FOR THIS CLASS OF PROBLEMS. SIGNIFICANT EMPHASIS WILL BE PLACED ON CODE PORTABILITY AND EASE-OF-USE. THE CODE WILL HAVE LIMITED VERIFICATION AND DOCUMENTATION IN PHASE I, AND IT WILL BE ENHANCED IN PHASE II.
