Zolkin I. Development of a system of automated ecological tritium monitoring at the nuclear fuel cycle facilities of Ukraine.

The object of study: radiation and environmental markers - the harbingers of change in a regular situation in the operation of nuclear facilities. Objective: to create an automated system of ecological monitoring of tritium on the nuclear fuel cycle facilities to enhance the environmental safety of the nuclear fuel cycle. In carrying out the work were used theoretical and experimental methods of nuclear physics; probability theory; theory of errors and methods of statistical analysis of time series; computer simulation methods. In carrying out the work were obtained following scientific results. For the first time: the physical model for monitoring tritium was developed; a mathematical model of the automated environmental monitoring of tritium was developed; an experimental laboratory model of the main element of the system for monitoring tritium was developed. A new important information component of the radiation monitoring and forecasting of emergency situations at nuclear fuel cycle is developed - a system for environmental monitoring of tritium. A specialized software that implements the model are developed, trial operation of hardware monitoring is conducted. The results of the thesis are introduced to practical use at nuclear power facilities of Ukraine together with the Corporation "Ukrainian nuclear devices and systems" (Acts introduction of 19.12.2011 and 19.12 .2013 ).
