Data Processing
NEC’2011
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

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.
