WebMar 31, 2024 · This report summarizes the results of a three-year research project sponsored by the U.S. Department of Energy (DOE) Nuclear Energy University Program (NEUP) to enhance and apply the RELAP-7 code by adding and improving several important components (e.g., a mechanistic Reactor Core Isolation Cooling (RCIC) system model) … WebFeb 9, 2024 · How Nuclear Reactors Work. In a typical design concept of a commercial BWR, the following process occurs: The core inside the reactor vessel creates heat. A steam-water mixture is produced when very pure water (reactor coolant) moves upward through the core, absorbing heat. The steam-water mixture leaves the top of the core …

WebIce condenser containment building. The ice condenser containment system uses the concept of ice chambers. The high-pressure steam following LOCA or MSLB conditions is directed into chambers containing baskets filled with ice. In these chambers, the steam is condensed, and this acts against the pressure increase. BWR containment buildings. WebThe passive BWR ECCS features implemented in the simulator include the following systems: Gravity Driven Cooling System (GDCS) Automatic Depressurization System (ADS) Isolation Condenser System (ICS) Standby Liquid Control System (SLCS) The simulator has a user–machine interface that mimics the actual control panel instrumentation.
