Web13 apr. 2024 · The danger of indiscriminately releasing nuclear fission products into the ocean is that the products can find their way into the food chain. Once in the food chain the nuclear fission heavy nuclei like cesium-137, strontium-90 and iodine-131 tend to concentrate in human muscle, bones, and thyroid. Cancers can be the result. Web1 dag geleden · This increase of temperature favours the release of some Fission Products (FPs), including iodine, which migrate through fuel cracks toward the cladding. At the same time, the stress level in the cladding also increases. The combination of these three phenomena can lead to I-SCC and may cause cladding failure.
