U.K.’s NWS gets input from young people on geological disposal
Nuclear Waste Services, the radioactive waste management subsidiary of the United Kingdom’s Nuclear Decommissioning Authority, has reported on its inaugural year of the National Youth Forum on Geological Disposal forum. NWS set up the initiative, in partnership with the environmental consultancy firm ARUP and the not-for-profit organization The Young Foundation, to give young people the chance to share their views on the government’s plans to develop a geological disposal facility (GDF) for the safe, secure, and long-term disposal of radioactive waste.

The total separation energy, including redox and pumping energy, was calculated using recent experimental data from the “super” chemical enrichment process. The redox energy mainly depends on the reflux ratio of the redox agents and the inverse redox reaction in the enrichment columns. The total energy consumption is ∼100 kW·h/separative work unit and the redox energy per separative work unit decreases with higher product assay. This chemical enrichment process is advantageous for recovering higher (1 to 5%) enriched uranium.
