The substance and implication of PR from the viewpoints of risk evaluation on nuclear proliferation was studied in this paper. As an example, ten next-generation reprocessing technology candidates were evaluated with GIF PR and PP methodology to find degree of relative difference in PR from the presently available technology - PUREX. PR effectiveness in proliferation risk was also assessed and it was found that the effectiveness of PR measures is subject to the status of each nation.

We have measured inelastic neutron scattering in CuMoO to study its magnetic-excitation dispersion curves. This material can be treated as a complex of the following two spin subsystems. (1) Quasi-one-dimensional antiferromagnetic (AF) spin chain with the intrachain interaction pJ4 = 6.3 meV, where p is the renormalization factor depending on the system dimension, together with the ferromagnetic and AF interchain interactions -Ja = J 0.01pJ4. (2) AF spin dimers with the interaction J3 = 5.8 meV. The hybridization parameter, representing the intersubsystem interaction between these subsystems, is estimated as Eint sin (k), where Eint = 1.6 meV. The modulation of the molecular field generated by the spin precession in the excited state of the quasi-one-dimensional spin chain plays an important role in this hybridization.
