IAEA project aims to develop polymer irradiation model
The International Atomic Energy Agency has launched a new coordinated research project (CRP) aimed at creating a database of polymer-radiation interactions in the next five years with the long-term goal of using the database to enable machine learning–based predictive models.
Radiation-induced modifications are widely applicable across a range of fields including healthcare, agriculture, and environmental applications, and exposure to radiation is a major factor when considering materials used at nuclear power plants.

Neutronics analysis is presented for a compact high wall loading (HWL) tokamak reactor with a major radius of 2.6 m, an aspect ratio of 4.33 and a fusion power of 1025 MW. A normal bean coil is used to achieve a high β value of 20%. The peak and average wall loadings are 12 and 8.7 MW/m2. No breeding blanket is used on the inboard side. The impact of using different materials on the overall TBR is assessed. Despite the limited breeding blanket coverage, an overall TBR > 1.05 is obtained when a 10 cm thick layer of a neutron multiplier is used on the inboard side above and below the bean coil. The total reactor thermal power is ∼ 1300 MW.
