Tokyo Electric Power Co. <9501> said Tuesday the amount of highly radioactive water leaking into the Pacific Ocean from its stricken Fukushima No. 1 nuclear power station appears to have fallen slightly.
The perceived decrease came after the operator of the plant injected liquid glass and a hardening agent into the gravel layer under a concrete pit that is near the water intake of the plant’s No. 2 reactor, company officials said.
The liquid glass, which hardens and helps block the flow of water, seems to have had some effect, the officials said.
The company plans to continue liquid glass injection into the gravel layer. A total of 12,000 liters of liquid glass have been prepared.
Tokyo Electric Power discovered water leaking through a crack near the floor of the power cable storage pit on Saturday and has since tried to stop the flow.
