An ICTP-IAEA Hybrid Meeting
This workshop will introduce the influence of ionization radiation from encapsulated radionuclides on waste forms and different modelling approaches for assessing safety under storage or disposal conditions.
Nuclear energy is a reliable solution to a finite energy supply from fossil fuels. All Member States (MSs) that benefit from the peaceful uses of nuclear energy have some amounts of radioactive waste to manage in a way that it does not present a burden to future generations.
To identify the preferred approach, a safety case is constructed that includes the assessment of the long-term impact of the various waste management and/or remediation options over a defined lifetime. Ionizing radiation, that arises from radionuclide decay will interact with waste form materials, resulting in collision cascades, defects, dislocations and phase separation that could influence the long-term stability and integrity of the waste form and its ability to isolate radionuclides from the environment.
Computer codes modelling the influence of ionizing radiation as part of degradation modelling of waste forms and waste packages, are developed and understood only by a few researchers in this field. Unfortunately, the use of such codes in limited due to the lack of suitably trained scientists and engineers, national resource and lack of knowledge on the subject matter.
IAEA is partnering with International Centre for Theoretical Physics (ICTP) to deliver a workshop to teach the modelling of ionizing radiation (that arises from radionuclide decay) on the properties of a waste form and use this information to design long-term storage facilities and management procedures.
