Long-Lived Fission Product Transmutation Studies
A systematic study on long-lived fission products (LLFPs) transmutation has been performed with the aim of devising an optimal strategy for their transmutation in critical or subcritical reactor systems and evaluating impacts on the geologic repository. First, 99Tc and 129I were confirmed to have highest transmutation priorities in terms of transmutability and long-term radiological risk reduct...
متن کاملTransmutation of Long-lived Fission Products in a Sodium-cooled Atw System
To devise an optimal strategy for transmuting long-lived fission products (LLFPs) in fast systems, various design studies have been performed for a sodium-cooled Accelerator Transmutation of Waste system. For Tc and I target assemblies loaded with metallic Tc and CaI2 targets and ZrH2 moderator, assembly design studies were first performed, focused on the optimisation of neutron spectrum and th...
متن کاملNuclear Development ACTINIDE AND FISSION PRODUCT PARTITIONING AND TRANSMUTATION
Partitioning and transmutation (P&T) aims at making nuclear energy more sustainable from the viewpoint of the back-end of the fuel cycle by minimising the high-level waste with respect to its mass, radiotoxicity and (possibly) repository risk. P&T mainly deals with the management – i.e. transmutation and/or special conditioning and confinement – of minor actinides and fission products, but invo...
متن کاملTransmutation of Fission Products
Studies of transmutation of long-lived fission products by accelerator and by fission reactor at PNC are described. Four transmutation methods by accelerators are compared in terms of transmutation energy and transmutation rate. A super-powered electron linear accelerator which could transmute a large quantity of fission products has been studied and development of PNC test linac in this line i...
متن کاملMinimizing the Integrated Collective Radiation Dose and the Transmutation of Long-lived Nuclear Waste
For more than a year, ECN is engaged in a research programme on transmutation of actinides as well as of fission products by means of respectively fission and neutron capture. It is intended to contribute to international efforts, which evaluate recycling options of the nuclear waste problem. Besides studies on strategy and scenarios, efforts are made to demonstrate possibilities for transmutat...
