Long-term Environmental Impact of Underground Disposal of P&t Waste
نویسندگان
چکیده
The long-term radiological impact of underground disposal of vitrified HLW (high-level waste) resulting from different P&T strategies has been evaluated. The considered P&T strategies include recycling of Pu and Np in homogeneous mode and Am in heterogeneous mode in CAPRA reactors or EFRs (European Fast Reactor). The safety assessment has been performed for three different types of host rocks, i.e. hard rock, salt and clay. For comparison assessments have also been made for the direct disposal of irradiated classical PWR UOX and UOX and MOX fuel, and of CAPRA and of EFR fuels. The key radionuclides have been identified and the capabilities for their partitioning and transmutation have been assessed.

متن کاملDesigning Low Impact Wastewater Discharge from Solar Distillation Site to Sea
Dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. However, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. Waste must be disposed of with the least effect on the receiving environment (sea, in most cases). Initial dilution and its characteristics play important roles in...
