Irradiation start in WP5

Yesterday (June 1, 2021) we started irradiation of sixty aggregate samples. This is a very important phase in work package 5 Assessing the performance of irradiation of concrete.

All samples were inserted into two capsules and put into active zone of light water research reactor LVR-15 being operated by Research centre Rez in Husinec-Rez near Prague (Czechia).

Target neutron fluence of irradiated samples is 4.43×1019 n/cm2 (> 0.1 MeV). End of irradiation is planned for 2021 October 14.

Process of post-irradiation examination will follow in Research Centre Rez as well.
