Reactor containment structure

A reactor containment structure, comprising:

• a reactor containment vessel;
• a reactor containment chamber which is installed inside the reactor containment vessel to contain a nuclear power reactor;
• a pool which is installed inside the reactor containment vessel so as to be below the reactor containment chamber adjacently and in which an emergency cooling liquid is stored;
• an opening part which allows the emergency cooling liquid to flow from the reactor containment chamber to the pool;
• a sump which is installed below the pool;
• a debris filtering body which is installed at the sump to filter debris contained in the emergency cooling liquid;
• a pumping system which sucks the emergency cooling liquid from the sump to discharge the emergency cooling liquid into the reactor containment chamber;
• and
• a debris trapping part which is installed in the pool to trap the debris,
• wherein the debris trapping part intersects with a flow path of the emergency cooling liquid flowing from the opening part to the pool and flowing toward the sump.
