Japan ReactorsJapan Reactors, Japan called for a power company yesterday to suspend the three reactors of a coastal nuclear power, while a sea wall and other structures are designed to help secure a major earthquake or tsunami crisis radiation causes a second.
The decision came as the government is conducting a safety review of all 54 nuclear reactors in Japan after the Fukushima Daiichi nuclear power plant is overshadowed by the March 11 earthquake and tsunami that left more than 25,000 dead and missing on the northeast coast.

The Hamaoka nuclear power plant, which is only 110 meters from the Pacific coast of central Japan, is the only so far the government has requested that operations be stopped until the utility can implement security measures.

Chubu Electric Power Co., said in a statement that “rapidly cuenta”la government request. Government officials estimate the work could last two years.

Prime Minister Naoto Kan, said last night that called for the closure for safety reasons, citing expectations of a 90 percent probability of an earthquake of magnitude 8.0 or greater striking the center of Japan within 30 years.

The government asked Chubu Electric to suspend two reactors running and a third was closed by a periodic inspection at the plant in Shizuoka, about 124 kilometers west of Tokyo.

Chubu Electric has established security measures including construction of a dike about a mile long in the next two or three years. “The height of the dam is at least 12 meters. We have come with this safety after the earthquake and tsunami of March,”said Takanobu Yamada, an official at Chubu Electric.

The company also plans to erect concrete walls along 18 water pumps. Yamada said the walls designed to protect the pumps from damage caused by an earthquake or a tsunami, and Take 1 to 1 1 / 2 years to complete.

The plant does not have a concrete barrier of the sea now, but the hills of sand between the sea and the plant are about 32 to 50 feet, the company said.

The dam of at least 40 feet to be built between the hills of sand and nuclear plants over the next two or three years. Yamada said Chubu Electric has estimated it would offer protection against a tsunami reaching 26 feet.

Tokyo Electric Power Co., operator of the affected plant Fukushima, said the waves had destroyed critical systems at least 46 feet high.
