Abstract

PURPOSE:To analyze many kinds and trace amounts of impurities containing in cooling water and a waste liquid, etc. of a nuclear reactor with high sensitivity and high accuracy, by using a photoacoustic analysis method. CONSTITUTION:Sample water is transferred from a nuclear reactor building 11, a turbine building 10 and a nuclear reactor primary storing vessel 12, etc. to a sample pretreating device 6 in a measuring room 8 through a transfer piping 9. The sample separated by the pretreating device 6 is packed in a photoacoustic analyzing cell 7 and light sent from a light source 1 such as argon laser is irradiated through an optical fiber 5. A photoacoustic signal sent from the cell 7 is processed and recorded by a controlling and recording device 2 in a control room 3 through a communication line 4. A series of operations is controlled by the device 2. The measured sample is passed through a transfer piping 13 and is treated in a waste treating building 14.
