Project summary

Project tasks:
1. Calculation and experimental study of europium g-sources manufactured from control rods spent in power and research reactors.
2. Classification of europium g-sources depending on operation and exposure time, dose rate and specific activity.
3. Development of proposals on europium spent rods transportation, long-term storage and utilization.

Results of the work will be used to certificate the new type of Eu-152, 154, 155 g-sources fabricated from spent control rods of nuclear reactors. These results will assistance in the utilization and storage of those europium rods which could not be used for production of g-sources.

Expected Results:

1. Characteristics of control rods spent in research, power and transport reactors.
2. Classification of rods with a dose rate and specific activity to optimize their further arrangement in gamma-device.
3. Classification of rods in geometrical size.
4. Proposals for long-term storage and utilization of europium rods.

The Possibility for Participation of Foreign Partners:

Joint work on introduction of europium g-sources in operating or developed devices on radiation treatment of articles, materials, foodstuffs and medical products, sewages and industrial water.
