Tokyo Electric Power Company has been trying to reduce a high level of radiation discovered in the Number 4 reactor of the troubled Fukushima Daiichi nuclear power plant.

The utility started to inject water into a pool on the top floor which was used for storing large equipment contaminated by radiation on Sunday.

The Number 4 reactor was shut down for a routine inspection when it was hit by the earthquake and the tsunami on March 11th.

Large hardware in the reactor was removed and was submerged in the pool to block the release of radiation.

Tokyo Electric Company discovered that the water level of the pool had dropped to about 1/3 of its capacity as of June 11th.

The machinery is thought to have been exposed and releasing high amounts of radiation.

The operator fears it could hamper restoration work in the Number 4 reactor.

TEPCO says the radiation level on the top floor is so high that workers cannot enter, but if the equipment is submerged again, the radiation level will decline enabling operations to restart.
