Japan's Fukushima Daiichi nuclear plant is under the spotlight once again.<br/> <br />Tepco, which runs the plant, is still dealing with damage from the earthquake and tsunami of 2011.<br/> <br />Now they say groundwater radiation levels have risen significantly in the last week.<br/> <br />The soaring radiation levels suggest highly toxic materials from the plant are now close to the Pacific Ocean.<br/> <br />Tepco has been flushing water over its reactors to keep them cool for more than two years, but contaminated water is building up at the rate of an Olympic-size swimming pool per week.<br/> <br />In April, Tepco sought approval to channel what it has described as 'groundwater with low levels of radiation' around the plant and to the sea.<br/> <br />Local fishermen oppose the proposal.
