Technical Centers collect, input, quality control and store their member’s countries data, and distribute data on occupational exposure and information of dose reduction techniques, as well as manage and analyse such data.

・ Dosimetric information from commercial nuclear power plants in operation or some stage of decommissioning includes, for example, for each participating unit:
　- annual collective dose for normal operation;
　- maintenance/refueling outage dose;
　- collective dose for unplanned outage periods;
　- annual collective dose for certain tasks and worker categories.

・ Plant-specific information contains data pertinent to dose reduction, such as materials, water chemistry, start-up/shut down procedures, cobalt reduction program, etc.
　- Dynamic indicators
outage, hot spot and crud information, decontamination, etc.
　- Static indicators
component and material indicators, primary circuit water chemistry, etc.

・ Radiation protection information covers specific operations, jobs, procedures, equipment or tasks such as;
　- effective dose reduction;
　- effective decontamination;
　- implementation of work management principles.
