The operator of the troubled Fukushima Daiichi nuclear power plant is preparing for the powerful Typhoon Lionrock, Japan's NHK World reported. 
Tokyo Electric Power Company said on Monday workers secured electric cables and hoses. 
TEPCO said on Tuesday it will suspend work with cranes and other operations at the plant's port, which could bear the brunt of strong winds and waves. Depending on weather conditions, the firm may also call off outdoor work in other areas. 
It said when the most recent typhoon approached last week, heavy rain caused underground water levels to rise and threatened to flush contaminated water into the harbor. 
Workers are arranging pumps to draw up more ground water, and setting up additional pumps at wells used to observe water levels. 
There were concerns in the past that a downpour brought by a typhoon could cause contaminated rain water to flow through a drainage channel into the ocean. 
To address these fears, TEPCO rerouted the drainage system into the plant's inside port. It also raised the levels of barriers around tanks that store tainted water.
