초록	The HANARO,a multi-purpose research reactor of 30MWth,open-tank-in-pool type,has been under normal operation dince its initial criticality in February,1995.The HANARO is composed of inlet plenum,grid plate,core channel with flow tubes and chimmey.The reactor core channel is located at about twelve meters(12m) depth of the reactor pool and cooled by the upward flow that the coolant enters the lower inlet of the plenum,rises up through the grid plate and the core channel and comes out from the outlet of chimmey.A guide tube is extended from the reactor core to the top of the reactor chimney for easily un/loading a target under the reactor normal operation.But active coolant throuth the core can be quickly raised up to the top of the chimney through the guide tube by a jet flow.This paper describes an analytical analysis that is the study of the flow behavior through the guide tube under reactor normal operation and unloading the target.As results.it was conformed through the analysis results that the guide jet is suppressed under the top of the chimney after modifying the orifice diameter of 37.5 mm to 31 mm.
