ADVANCED FUEL BUNDLE IN CANDU REACTOR

摘要

PURPOSE: An advanced fuel bundle in a candu reactor is provided to maximize the operation efficiency of a heavy water reactor by controlling the diameter of a nuclear fuel rod and increasing a critical output. CONSTITUTION: A first bunch line(10) is arranged in outermost of a nuclear reactor as a circle type. A second bunch line(20) is arranged in the first bunch line as a circle type. A third bunch line(30) is arranged in the second bunch line as a circle type. A nuclear fuel rod is arranged at the center of the nuclear reactor while having a second diameter.
