Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Three nations, three ways to recycle plastic waste with nuclear technology
Plastic waste pollutes oceans, streams, and bloodstreams. Nations in Asia and the Pacific are working with the International Atomic Energy Agency through the Nuclear Technology for Controlling Plastic Pollution (NUTEC Plastics) initiative to tackle the problem. Launched in 2020, NUTEC Plastics is focused on using nuclear technology to both track the flow of microplastics and improve upstream plastic recycling before discarded plastic can enter the ecosystem. Irradiation could target hard-to-recycle plastics and the development of bio-based plastics, offering sustainable alternatives to conventional plastic products and building a “circular economy” for plastics, according to the IAEA.

An absolute scale for the differential cross sections of the reactions 3H(p, n)3He, 2H(d, n)3He, and 3H(d, n)4He, measured for incident energies between 6 and 17 MeV, was established using a calibrated time-of-flight system. Accurate charged-particle reference cross sections were inter-compared so that a common scale with an uncertainty of ±1.5% was obtained. By interchanging the target and beam nuclei, data were obtained at 180 deg in the original system for several cases. The new data were analyzed together with the previous data, and Legendre coefficients were extracted to permit presentation of the data between ∼5 and 20 MeV, thus extending and partly revising previous evaluations. The typical shape error of the angular distributions, as given by the Legendre coefficients, is <3% over the entire angular range. In addition, data on the neutron production at zero degree by breakup are given for the p-T and d-D reactions. By correcting the previous counter telescope data for the 1H(n, n)1H cross sections (according to more recent phase-shift analyses), scale ambiguities of ∼3% were resolved, thus indirectly verifying these phase shifts up to neutron energies of ∼16 MeV. However, at higher energies (above ∼23 MeV) for 3H(d, n)4He data, the corrected neutron counter telescope data deviate from the present analysis by ∼5%. Whether or not this difference is caused by the 1H(n, n)1H reference cross section used is open to further investigations.
