World Bank, IAEA partner to fund nuclear energy
The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

Understanding of the tritium release process from ceramic breeders is of importance to establish a reliable tritium recovery concept for fusion reactors. Release behavior of tritium produced in the neutron-irradiated Li4SiO4 is investigated by the Thermal Desorption Spectroscopy (TDS). Thermal annealing behavior of the irradiation damages was also studied by Electron Spin Resonance (ESR) method.
These experimental results showed that the annealing process of the damages occurred in the almost same temperature range of tritium released from the neutron-irradiated Li4SiO4. This suggested that the thermal annealing processes of the damages were closely correlated with the tritium release process. It was also found that the thermal annealing consisted of two processes. The activation energies of the two processes were determined to be 0.5 eV and 0.96 eV, respectively.
