Organization of isotopic monitoring of heavy water by infrared spectrometry at pik reactor

This work is devoted to the problem of isotopic heavy water control on PIK reactor. The results of IR-spectroscopic heavy water investigation for the purpose of correct isotopic analysis are shown. The methods that are used for the laboratory control of deuterium concentration (aD) of heavy water in reactor system and heavy water installation of PNPI are presented. It is proposed to use infrared spectrometry for isotopic on-line control of heavy water coolant at PIK reactor.
