Could granite solve the hard problem of the nuclear waste storage?

4 June โ€“ We need to search somewhere a place to dispose of high level of nuclear waste. A safe place that will keep them separated for many years. Moreover, if we want to fight the global warming then we must search this kind of place to keep carbon dioxide too.

A research study released by Scientific Reports  reported that crystalline rocks, like granite, have a natural and automatic process to steal itself and have capacity to isolate fluids for thousands of years.

A close analysis of the chemistry and granite by Japan and United Kingdom disclosed that when fluid went into the rock, it hardly moved. The scientists think that, the calcium situated in the rock responded with carbonate in the fluid to generate tiny crystals that blocked all the gaps and stopped further flow. As Roy Wogelius from the University of Manchester said, โ€œThis amount of calcite would never be expected in a granite, and the distribution of it indicates it almost certainly formed from small quantities of fluid trying to move through the rock,โ€.   

Even if we need to develop an excellent understanding before we conclude our radioactive waste disposal master plans, this might be considered an encouraging step.
