Despite its disadvantages, nuclear power still has some advantages over traditional fossil fuels and could have a part to play in solving the current energy crisis. Among them, nuclear waste (mainly uranium and plutonium) is the inevitable product of the extensive development and application of nuclear power, and its recovery and storage technology are on the focus of scientific research. Herein, amidoxime‐modified hollow organic porous nanospheres (HOPNs‐AO) were prepared by co‐hyper‐crosslinking from polylactide‐b‐polystyrene (PLA‐b‐PS) diblock copolymer and benzeneacetonitrile based on the Scholl coupling reaction. Owing to the specific adsorption property of amidoxime groups for uranyl ions, the obtained HOPNs‐AO exhibited excellent adsorption capacity (qmax=519.5 mg ⋅ g−1), chemical stability, and selectivity for uranyl ions in an aqueous solution. In addition, HOPNs‐AO can still maintain more than 80 % adsorption capacity in the fifth cycle. The above results indicate that the successful design of this material provides a meaningful way for the recovery of uranium ions in aqueous solution.

Rare earth-doped nickel (Ni-RE) alloys are very attractive for the neutron shielding application for excellent neutron absorption and good mechanical behavior. Ni-RE intermetallics are important for their precipitation reinforcement in Ni alloys. In this work, Ni-RE intermetallics have been founded to be Ni grain refiners, which has been proved both by nucleation crystallography analysis and experiments. Ni-RE intermetallics could work as heterogeneous nucleation well, either different in atomic structures (for example, Ni17RE2, Ni5RE, Ni7RE2, Ni3RE, Ni2RE having matching orientation relationships as (111)Ni // (0004)Ni17Gd2 with [ 1 1 ¯ 0 ] Ni / / [ 01 1 ¯ 0 ] Ni17Gd2 , (111)Ni // (0002)Ni5Gd with [ 1 1 ¯ 0 ] Ni / / [ 01 1 ¯ 0 ] Ni 5Gd , (111)Ni // (00018)Ni7Gd2 with [ 1 1 ¯ 0 ] Ni / / [ 01 1 ¯ 0 ] Ni7Gd2 , (111)Ni // (00012)Ni3Gd with [ 1 1 ¯ 0 ] Ni / / [ 01 1 ¯ 0 ] Ni3Gd , (111)Ni // (222)Ni2Gd with [ 1 1 ¯ 0 ] Ni / / [ 1 1 ¯ 0 ] Ni2Gd ) or different in rare earth element (for example, (111)Ni // (0002)Ni5RE with [ 1 1 ¯ 0 ] Ni / / [ 01 1 ¯ 0 ] Ni5RE is general matching orientation relationships (ORs) of Ni5RE (RE = Sc, Y, La ~ Lu) for Ni grains). When RE dopant mass fraction is 1 wt%, the grain size is reduced from ~50 μm to 15 μm, and the refinement effect reaches the best. The work proposes Ni-RE intermetallics as good heterogeneous nuclei for Ni grains with an atomic level understanding and provides theoretical guidance for high-strength nickel alloy design.

“…Furthermore, nuclear power provides diversity in electricity and in primary energy supply and contributes to making electricity systems more flexible and enhancing energy security. Nevertheless, new investments and lifetime extensions of nuclear power plants are often hindered by poor public acceptability, which has been strongly affected firstly by the occurrence of severe accidents and secondly by a nuclear fuel cycle producing a large amount of radioactive and toxic waste [10,11].…”

In this work, the feasibility of nuclear processes is studied via classical thermodynamics by assessing the change in entropy, a parameter that has so far been neglected in the analysis of these reactions. The contribution of the entropy to the reaction spontaneity plays a different role in the fission and fusion reactions. In particular, in fusion reactions the temperature acts as a very powerful amplifier of the entropic term (−T ΔS) that, at the temperature of tokamaks (millions Kelvin), may significantly reduce the thermodynamic spontaneity of these processes. A new approach is followed for assessing the feasibility of the D-based reactions of interest for the magnetically confined nuclear fusion through the investigation of the effect of the temperature on both kinetics and thermodynamics. The results confirm that the deuterium–tritium reaction is the most promising fusion reaction to be realized in tokamak devices. At the temperature of 1.5 × 108 K (≈13 keV), the DT reaction exhibits a large thermodynamic spontaneity (ΔG = 16.0 MeV) and its reactivity is of the order of 10−22 m3/s, a value capable of guaranteeing the tritium burning rate needed to operate the nuclear plants under tritium self-sufficiency conditions and with a net energy production. The other results show that at the tokamaks’ temperature the two branches of the DD reaction exhibit a modest spontaneity (ΔG around −2 MeV) coupled to very low reactivity values (10−24 m3/s). The temperature rise that could be aimed to increase the reactivity is however ineffective to improve the reaction feasibility since it would augment the entropic term as well, thus shifting the ΔG towards positive values. The D3He reaction is soundly spontaneous at the tokamaks’ temperature (ΔG values of −17.2 MeV) while its kinetics is close to that of the DD reactions, which are at least two orders of magnitude lower than that of the DT reaction.
