Radioactive Waste 85 -Russia and Norway Cooperate in Exploring Nuclear Dump in the Kara Sea

        I have blogged before about the nuclear waste situation in Russia. In one post, I discussed how Russia had been taking in illegal shipments of nuclear waste from European countries. I have also discussed how Russia has been dumping nuclear waste into the sea around the port of Murmansk. Now a report on the decades of Russian dumping into the Kara Sea of the Arctic Ocean has been provided by the Russians to the Norwegians.

Radioactive Waste 84 - France is Working on a Permanent Geological Repository for Nuclear Waste

         Nulcear waste disposal is a great unsolved problem. Geological repositories have been created by some nations but some have had to be closed because of unanticipated problems. In the U.S., years were spent working on a Yucca Mountain repository in Nevada before the project was cancelled in 1999. The best current estimate is that there will be no permanent geological repository in the U.S. before 2050.

Nuclear Reactors 140 - Experiments on Nuclear Core Meltdowns

         Corium is a name that was coined for the molten material that results when the fuel of a nuclear reactor melts down in a nuclear accident. It contains nuclear fuel, fission products, control rods, structural material, and chemical reaction products with air, water and steam. If the reactor core is breached, then there will also be molten concrete in the mix. There is currently a debate about the fate of the corium created during the nuclear disaster at Fukushima in March of 2011.
