How to protect underground water flowing into Fukushima Nuclear Facility. Using by heat pipes and LNG

We invented an innovative artificial permafrost forming method to prevent the flowing of under-ground water into Fukushima nuclear facility. In this proposal, heat pipes are embedded at all around of the nuclear facility to cool the hygroscopic soil effectively, and LNG is used as both a cold source and the fuel of 1,000,000,000W gas-turbine electric generator. We calculated artificial permafrost wall forming by transient calculation at several condition, and we also calculated maximum amount of heat transport of heat pipe. Based on the result, we confirmed that this proposal have a good feasibility. Finally, we estimated the total cost of this proposal. (author)
