SYSTEMS AND METHODS FOR DETECTING A LEAKING FUEL CHANNEL IN A NUCLEAR REACTOR

摘要

The present invention provides a method and system for detecting individual leaky fuel channels in a nuclear reactor. One system includes a plurality of inlet lines and a plurality of outlet lines. Each of the plurality of inlet lines supplies the annuclear fluid in parallel to the annular space of each of the plurality of first fuel channels included in the nuclear reactor, and each of the plurality of discharge lines includes a plurality of second fuel channels included in the nuclear reactor. Collect the annular fluid exiting the annular space in parallel. In some embodiments, the system further comprises a detector located at the outlet of each of the plurality of outlet lines, the detector being configured to detect moisture in the annuus fluid and also to locate a first location of the respective leaky fuel channel. , The system also includes an isolation valve located at the inlet of each of the plurality of inlet lines, the isolation valve stopping the circulation of the annular fluid through one of the plurality of inlet lines and further It can act to find out the location.
