Product Information

Features

Reactor Vessel Internals are designed to support and orient the reactor fuel assemblies and direct coolant flow through the core. Made of stainless steel, the 12-meter long internals weigh about 180 tons.

Descriptions

Guide Structure Support System
Guide Structure Support System guides the vertical movement of the control element assembly's extension shaft, and has multiple flow holes for the flow of coolant to the Closure Head Assembly
Upper Guide Structure
Upper Guide Structure restricts/supports the upward movement of fuel assembly and provides channels for coolant to pass through the CEA Shroud. The control rod guide tubes guide the control rod passing through the tubes, and protect the control rod from the pressure of coolant flowing through the nozzle.
CEA Shroud
CEA Shroud prevents the interferences with nearby control rod, and guides the vertical movement of control rod. It also protects the control rod from the Cross flow of coolant.
Core Support Barrel
Core Support Barrel contains and supports the fuel assembly, core shroud and lower support structure, and shields from radioactivity along with coolant. Linked with reactor vessel's exit nozzle, the nozzle attached to the cylinder minimizes the coolant leakage. Its six snubbers restrict the radius and circumference directions.
Core Shroud
Core Shroud shelters the reactor fuel and stabilizes the flow of coolant, which is injected from LSS and flows around the fuel. Guide Lug, inserted into the keyway at the Fuel Alignment Plate of Upper Guide Structure, restricts the horizontal movement of Core Shroud.
Lower Support Structure
Lower Support Structure contains and supports Fuel Assembly, Core Shroud and ICI Support System. The pins at the top of the lattice beam lock the position of reactor fuel.
