Japan urged a power company Friday to suspend all three reactors at a coastal nuclear plant while a seawall and other structures are built to ensure a major earthquake or tsunami does not cause a second radiation crisis, according to AP. The move came as the government is conducting a safety review of all Japan's 54 nuclear plants after the Fukushima Dai-ichi nuclear plant was crippled by the March 11 earthquake and tsunami that left more than 25,000 people dead and missing on the northeast coast. The Hamaoka nuclear plant just 110 yards (100 meters) off the Pacific coast in central Japan is the only one so far where the government has asked that operations be halted until the utility can implement safety measures. Chubu Electric Power Co. said in a statement it will "swiftly consider" the government's request. The statement gave no further details. Government officials estimate the work could last two years. Prime Minister Naoto Kan said at a news conference Friday evening he requested the shutdown for safety reasons, citing experts' forecast of a 90 percent probability of a quake with magnitude of 8.0 or higher striking central Japan within 30 years. "It was a decision made after thoroughly considering people's safety," Kan told a news conference. The government asked Chubu Electric to suspend two running reactors and a third already shut for a regular inspection at the plant in Shizuoka, 155 miles (250 kilometers) west of Tokyo. "If an accident occurs at Hamaoka, it could create serious consequences," Kan said. Since the March 11 disasters, Chubu Electric has drawn up safety measures that include building a seawall nearly a mile (1.5 kilometers) long over the next two to three years. "The height of the seawall is at least 12 meters. We have come up with this safety measure after the March quake and tsunami," said Takanobu Yamada, an official at Chubu Electric. The company also planned to erect concrete walls along 18 water pumps at the plant. Yamada said the walls aimed to protect the pumps from damage from an earthquake and tsunami, and it will take a year or one and a half years to complete the construction. The plant does not have a concrete sea barrier now, but sandhills between the ocean and the plant are about 32 to 50 feet (10 to 15 meters) high, according to the company. The seawall of at least 40 feet (12 meters) would be built between the sandhills and nuclear plant over the next two to three years. Yamada said Chubu Electric has estimated a tsunami reaching around 26 feet (8 meters). Trade Minister Banri Kaieda said the utility company should halt operating its nuclear reactors while implementing such safety measures. He argued Chubu's safety measures were "not enough" without elaborating further. "Until the company completes safety steps, it is inevitable that it should stop operating nuclear reactors," Kaieda said. Shizuoka governor Heita Kawakatsu called the government's move "a wise decision." "I pay my respect for the decision. We must do our utmost to secure alternative sources of energy," the governor said in a statement.
