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 efficient groupwise rebalancing technique for accelerating the iterative solution to the integral transport equation is described, and the results obtained for a number of unit cell problems with the lattice analysis code HAMMER are presented to demonstrate its efficiency. For light water reactor lattices, a factor of 2 or more saving in central processor unit time of the CDC 7600 computer was observed.
