Japan scrambles to protect damaged reactor from typhoon

Tokyo, Japan (CNN) -- Workers in Japan scrambled Monday to build a protective covering over a damaged nuclear reactor ahead of an approaching powerful typhoon, an energy company spokesman said.

Typhoon Ma-on -- currently a "Large" and "Very Strong" storm, according to the Japan Meteorological Agency -- should strike Japan well south of the damaged no. 3 reactor at the crippled Fukushima Daiichi nuclear power plant.

But the Tokyo Power Company, which is responsible for the plant wracked by the March 11 tsunami that struck northeast Japan, is constructing a "roof-like structure to prevent rain from entering holes on the turbine building," said spokesman Satoshi Watanabe.

The energy company says it aims to complete construction late Monday.
