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.

Resonance parameters for 74 resonances of 165Ho below 500 eV, selected from the literature and from values compiled and recommended in BNL-325, are used as the starting point in fitting the total neutron cross-section data to a sum of the Breit-Wigner multilevel scattering and single-level capture formulas. The addition of two bound levels, one for each s-wave spin state, yields a calculated ratio of thermal neutron capture cross sections for the two s-wave spin states which agrees with experiment (≈60% of thermal capture into J = 3 states), as does the calculated value of the thermal capture cross section, 67 b. In addition, the two bound levels enable the fit of the total cross-section data to be extended to very low energies (0.2 mV). The coherent scattering cross section has been calculated and is in good agreement with the experimental value of 9.1 b. The free atom nuclear scattering cross section has been calculated to be 10.6 b. The calculated value of the potential scattering is 7.8 b and the effective scattering radius is 7.9 f. The energy-dependent paramagnetic scattering cross section (23.5 b at 0.0253 eV) and the capture and scattering resonance integrals have also been calculated (≈703 and 125 b, respectively).
