Method and system for external alternate suppression pool cooling for a BWR

摘要

A method and system for external alternate suppression pool cooling for a Boiling Water Nuclear Reactor (BWR) that does not breach the Mark I primary containment. The external cooling system may include a heat sink (20) fluidly coupled to cooling coils (26) surrounding the suppression pool (2). Cool water may be pumped through the cooling coils (26) without the need for normal plant electrical power, which is ideal during a plant emergency. The cooling system (30) may also be operated and controlled from a remote location to protect the safety of plant personnel.
