TOKYO (AP) - A Japanese power company says it will "swiftly consider" a request from the country's prime minister that it shut down three reactors until safety measures have been put into effect.
A seawall and other structures are envisioned to protect the plant from the impact of a major earthquake and tsunami like the one that caused a radiation crisis at another Japanese nuclear plant in March.
Government officials estimate that the work could last two years.
The plant is a little more than 100 yards off the Pacific coast in central Japan. It's the only one so far where the government is asking that operations be halted until it can be made safer.
The prime minister cited experts' forecast of a 90 percent chance of a powerful quake hitting central japan within 30 years.
The government is conducting a safety review of all of Japan's 54 nuclear plants.
