Are materials engineering knowlege and technique used to solve Fukushima Nuclear Power Plant problem 1) After injecting the seawater to the cooling system of nuclear plant , boric acid solution was added to minimize corrosion2) Polymer resin was sprayed into the power plant to control the spread of radiation3) Polymar resin was injected into the vicinity sea to control the spread of radiation. 4) Colouring paint was used to trace the leak path5) Liquid glass( sodium Silicate) is used to seal the crack on the walls of retaining tank in order to reduce the leakage of contaminated water
