Tokyo Electric Power (TEPCO) has unveiled plans to stabilise the quake-hit Fukushima Daiichi plant in Japan, within six months.
The first three months of the two-part plan include installation of a cooling system where core reactor temperatures will fall below 100°C, to reduce radiation levels within .
The second part of the project will involve the introduction of a heat removal system and elimination of contaminated water.
TEPCO plans to place bags of sand and zeolite near the reactors to absorb radiation and to stop leakage of radioactive water into the sea from a pit near the No.2 reactor.
Water with lower levels of radiation has been removed from the treatment facility and trenches outside the No.5 and No.6 reactors, to make space for more contaminated fluids.
TEPCO said it plans to fill the reactor containment vessels with water in reactors No.1 and 3 and fill nitrogen in reactor contaminated vessels near reactors 2 and 3 to avoid hydrogen explosions.
TEPCO will also strengthen the walls and base of a pool containing spent fuel rods in the No.4 reactor building, reports Bloomberg.
The plant has six generating units, of which reactors Nos. 4, 5 and 6 were shut for maintenance before the quake and tsunami struck.
