Self-contained emergency spent nuclear fuel pool cooling system

Abstract

An auxiliary system for cooling a spent nuclear fuel pool through a submersible heat exchanger to be located within the pool. In each train or installation, a single loop or series of loops of cooling fluid (e.g., sea water or service water) is circulated. The system is modular, readily and easily installed during an emergency and can be self operating with its own power source. Multiple trains may be used in parallel in order to accomplish the required degree of spent fuel pool cooling required.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to Provisional Application Serial No. 61 / 469,184, filed March 30, 2011, entitled "Self-Operating Emergency Spent Fuel Pool Cooling System." technical field [0003] This invention relates generally to cooling systems for cooling water in nuclear reactor power generation facilities, and more particularly to temporary cooling system. Background technique [0004] In nuclear power generation facilities, the reactor vessel housing nuclear fuel and water are located in what are commonly referred to as the refueling chamber and the reactor chamber. During power generation, the primary fluid coolant (usually water) is heated by the nuclear fuel, and the heat is used to generate steam for power generation. During shutdowns for refueling and other phases when the reactor is not operating, the decay heat from the fuel continues to heat the water in the reactor vessel. Before fuel can be removed fro...
