On March 4, 2011 the acceptance testing of the IRD 2000 automated calibrating device, made by MGP Instruments, a French company, for DMS 2000 operation dosimeters was accomplished. The equipment put into operation became the last stage of modernization of Kola NPP operation individual radiation exposure survey.

Today this system not only provides the control of radiation dose for each worker, but also the monitoring of the personnel movements at the nuclear plant controlled access area. For this purpose, each plant worker, appearing at controlled access area, receives a dosimeter equipped with a data transmitter, which, in its turn, transfers the information of the movements and the radiation doze received to the head unit.

ТAll in all, there are 847 dosimeters at Kola NP, - reported Alexander Kuchin, Kola NPP Radiation Security Department Chief Engineer. Р Each of them should undergo annual calibration. Previously, it took over 8 months to test all the dosimeters. But thanks to introduction of the new IRD 2000 facility, we managed to reduce the calibration period up to two weeks only.

Today, Mirion Technologies is one of the world leading equipment producers for the systems of individual dosimetric control and radiation monitoring. In Russia, MGP Instruments has a positive experience of collaboration not only with Kola NPP. Earlier, the French company successfully introduced the systems of leakage control from the first to the second contours on nitrogen-16 for Kola, Novovoronezh, Kalinin, Balakovo NPPs. Similar systems are mounted at Rovensk and Armenian NPPs. 

Wilfred Matthew, MGP Instruments expert, also trained Kola NPP specialists to work with the equipment installed as a part of his visit.
