IAEA looks at nuclear techniques for crop resilience
The International Atomic Energy Agency has launched a five-year coordinated research project (CRP) to strengthen plant health preparedness using nuclear and related technologies.
Wheat blast, potato late blight, potato bacterial wilt, and cassava witches broom disease can spread quickly across large areas of land, leading to severe yield losses in key crops for food security. Global trade and climate change have increased the likelihood of rapid, transboundary spread.

A method was developed for incorporating moderator feedback effects in two-dimensional nodal codes used for pressurized water reactor (PWR) neutronic analysis. Equations for the assembly average quality and density are developed in terms of the assembly power calculated in two dimensions. The method is validated with a Westinghouse PWR using the Electric Power Research Institute code SIMULATE-E. Results show a several percent improvement is achieved in the two-dimensional power distribution prediction compared to methods without moderator feedback.
