Abstract
Official abstract text for this publication.
The present invention relates to a top nozzle and a nuclear reactor in which an in-core instrument, which is supposed to be inserted through a top head of a nuclear reactor, is inserted through a guide pin for an upper core plate. In a nuclear reactor including guide pins for aligning a top nozzle for a nuclear fuel assembly with an upper core plate of a nuclear reactor, a guide hole (210) is axially formed through the guide pins (200) and in-core instruments (10) are inserted through the guide holes (210).
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for a nuclear fuel assembly, comprising: a top nozzle; and guide pins for aligning the top nozzle with an upper core plate of a nuclear reactor; wherein each of the guide pins has a guide hole axially formed therein, the guide hole extending from an upper end of a guide pin to an end of the guide pin located within a body of the top nozzle, and aligning with an aligning hole that extends through the body of the top nozzle and opens at a bottom surface of the top nozzle, the aligning hole, when the top nozzle is aligned with the upper core plate, being offset from a control rod assembly of the apparatus. 2. The apparatus of claim 1 , wherein the aligning hole is formed at a corner of the top nozzle. 3. The apparatus of claim 1 , further comprising a core instrument in the guide hole, and extending from the upper end of the guide pin through the end of the guide pin located within the body of the top nozzle into the aligning hole in the body of the top nozzle.
