Main Components of an Eporbwr System
The EPORBWR system integrates advanced nuclear technology through specialized components designed for optimal performance and safety. These components work together to create a reliable and efficient power generation system.
Core Design Elements
The reactor core features a compact arrangement of fuel assemblies with advanced uranium dioxide pellets encased in zirconium alloy tubes. The core design incorporates 732 fuel bundles arranged in a cylindrical pattern, optimizing neutron efficiency and power distribution. Control rods made from boron carbide regulate the nuclear reaction through precise vertical positioning. The core shroud directs coolant flow while maintaining structural integrity at high temperatures. Steam separators above the core remove moisture from steam before it enters the power generation cycle.
Safety Features
The containment vessel incorporates multiple barriers including a reinforced concrete primary containment structure rated for 75 psig pressure. Passive safety systems operate through natural circulation using gravity-fed cooling pools located 20 meters above the core. Emergency core cooling systems activate automatically without electrical power through steam-driven injection pumps. The suppression pool absorbs excess energy during transient events through 16 main steam relief valves. An isolation condenser system removes decay heat for 72 hours without operator intervention.
