DILUTING AND SAMPLING METHOD FOR COOLANT IN A REACTOR TO DISCHARGE THE COOLANT SAMPLE MIXED WITH DEIONIZED DILUTING WATER IN AN ACCIDENT OF THE REACTOR

摘要

PURPOSE: A diluting and sampling method for coolant in a reactor is provided to prevent the reduction of measurement accuracy due to the increase of dead time of a nuclide analyzer when the radioactivity level of a sample is too high.;CONSTITUTION: A diluting and sampling method for coolant in a reactor comprises the steps of: connecting a sample loop(1) to a sample loop joint(20), putting deionized diluting water into a diluting solution inlet part(30), discharging diluted sample through a diluted sample outlet part(40), storing the discharged diluted sample in a diluted sample storage part(50), and ejecting a certain amount of the diluted sample through a diluted sample dispensing part(60). The diluted sample storage part includes a water level sensor(51).;COPYRIGHT KIPO 2010
