Ivan Fast

Ivan Fast holds a Dr.-Ing. in Nuclear Waste Management from RWTH Aachen University. Ivan is a Radiation Protection and Radioactive Waste Management Engineer at PreussenElektra GmbH, with extensive practical experience in the dismantling of nuclear power plants and the management of complex radioactive waste streams. Since 2019, he has been working as part of the owner’s engineering staff on the dismantling of the Grafenrheinfeld Nuclear Power Plant, covering the full scope of waste management engineering from planning and assessment to on-site implementation.

His recent responsibilities include the ongoing dismantling projects of the Biological Shield, Steam Generators, and the management of historical high-radioactive operational waste. From 2023 to 2024, Ivan served as Sub-Project Leader for the dismantling of the Reactor Pressure Vessel, with direct responsibility for disposal pathways and nuclear waste management. His work comprised activation calculations, waste packaging, and disposal concepts, as well as the evaluation of sampling results. Earlier, he held the same role in the disassembly and disposal of Reactor Pressure Vessel Internals (2021–2022).

From 2018 to 2020, Ivan was Project Leader of the CASTOR Project, overseeing the relocation of all spent fuel assemblies from wet storage to dry interim storage using CASTOR® containers. This included the successful transfer of the remaining damaged fuel rods and resulted in the plant becoming completely nuclear-fuel-free, achieved on schedule. His responsibilities covered quality control of loading documentation and technical coordination with regulatory authorities and external suppliers.

Ivan is the author and co-author of several technical publications presented at international conferences and in peer-reviewed journals, including IEEE Transactions on Nuclear Science, with contributions to the WM Conference series (2013, 2015, 2024) and ANIMMA. His work has been recognized with the Best in Track #2 Poster/Paper Presentation Award (WM2015) and the Roy G. Post Scholarship (WM2013).
