Nanomagical Material Can Make Nuclear Reactors Safer [Science]

Nanomagical Material Can Make Nuclear Reactors Safer
Fighting cancer or making nuclear reactors that constantly self-repair themselves, helping to avoid the possibility of another Chernobyl. Clearly, nanotechnology will either save Earth or convert us into Borgs. Los Alamos National Laboratory scientists are betting on the first option.

Their new research work—published in Science—could make nuclear reactor much safer by using nanocrystalline materials. These materials are capable of patching the vacancies left by the atom collisions that result from atomic reactions. This is how it works:

Their computer simulations have shown that this materials can work at a large scale, using a newly discovered event called the 'loading-unloading' effect. The discovery will help build reactors that are resistant to the decay caused by the nuclear reactions themselves, which include 'swelling, hardening or embrittlement can manifest in the material and lead to catastrophic failure.'

Anything that can avoid 'catastrophic failure' seems like a good idea to me.
