Advances in Radiation Shielding for Fusion Reactors

Dr Juarez has participated in diverse European research activities to expand the computational capabilities of fusion neutronics, and their application to the design of both inertial and magnetic fusion reactors. His main field of research is the development of computational schemes like R2S-UNED and D1S-UNED to determine the shutdown dose rates and shielding related to fusion facilities. For his PhD., he proposed and developed the shielding and different neutronics aspects of the European HiPER reactor. Since then, he has been involved in the design of European DEMO reactors, and more importantly in ITER shielding aspects. Nowadays, he is the technical manager of the UNED team, which plays an important role in the ITER shielding design as high level nuclear analysis provider.

Dr Loughlin has been involved in nuclear fusion research for over 30 years which has included involvement in the historic first experiments in the use of Deuterium-Tritium plasmas at JET and TFTR. Over the last 10 years, as Co-coordinator of Nuclear Analysis and Shielding at ITER, he had led the drive to ever more sophisticated, powerful and precise predictions of the nuclear performance of fusion devices.

Dr Sanz is currently full professor at UNED, where he has directed over 20 PhDs. related to computational capabilities for the fusion radiation shielding design and their application in the conception of a wide range of nuclear fusion facilities. His career started in the 80's with the development of ACAB code, and its application to the shielding design of the National Ignition Facility (US). Since then, he has created and led a research team with over 30 researchers in the last 20 years. He has coordinated the development of relevant tools for the prediction of the radiation fields and their effects, which account for important contributions to the field, like ACAB, MC-UNED and the most advanced implementations of the rigorous two steps and direct-one-step methods, R2S-UNED and D1S-UNED respectively. All these tools were used under his leadership in the shielding design of the inertial reactors HYLIFE-II, SOMBRERO and HiPER, the magnetic reactors European DEMO saga and ITER, and the fusion related accelerators EVEDA, IFMIF, and DONES. His background and academic position grant him with a privileged overview of the status of the nuclear shielding for fusion reactors. Nowadays he is the coordinator of the UNED team, which plays an important role in the ITER shielding design as high level nuclear analysis provider.
