REACTOR AND OPERATING METHOD FOR THE REACTOR

摘要

Provided are a reactor and an operating method for the reactor, and more particularly, a reactor which may passively cool excessively generated heat without an operation of an operator at the time of abnormality of the reactor, completely passively perform the cooling operation for safety procedures by a structure of the reactor and a change in environmental conditions such as a pressure, etc., without a separate control command, and have a simpler structure than the existing reactor safety system, and an operating method for the reactor.

1. A reactor, comprising:
a reactor driving system configured to include a reactor vessel accommodating a reactor core and a steam generator to which a steam pipe and a water supply pipe are connected; and a reactor safety system configured by being divided into an energy release space (ESR) accommodating the reactor driving system, an energy absorbing space (EAS) communicating with the energy release space through a passage formed thereover and accommodating a coolant, and an energy transfer space (ETS) formed to be isolated from the energy release space and the energy absorbing space and having a heat exchange device provided therein to transfer heat released from the reactor driving system to the coolant, the heat exchange device being connected to the energy release space and the energy absorbing space, respectively; wherein the coolant within the reactor safety system is selectively distributed in response to thermal-hydraulic conditions changed depending on a change in pressure within the reactor driving system and whether the coolant is leaked to cool the reactor driving system.
