Data Processing The data processing module periodically stores logs to hard disk in individual files: • current levels of radiation • maximal levels of radiation during observation and the time of their appearance • exceedance of the threshold values: - time of its appearance - threshold exceedance duration - corresponding dose during the threshold exceedance in any channel • integral values of radiation levels • mean values of radiation levels during the shift • beam shutters status log Мурашкевич С.

Conclusion A new dosimetric control hardware and software complex for the IBR-2 reactor was put into operation in the winter of 2010. In the summer of 2011 the complex was successfully tested during the trial start-up of the modernized reactor. Мурашкевич С. М. ОИЯИ ЛНФ НЭОКС NEC’ 2011
