東京電力福島第一原発の事故を受けて、東北電力は１８日、女川原発（宮城県石巻市、女川町）の周囲に高さ３メートル（海面から１７メートル）の防潮堤を設けるなどの安全対策を発表した。原発を囲むように約８００メートルにわたり建設し、来年４月の完成を目指す。
東日本大震災を受けて、経済産業省原子力安全・保安院が電力各社に安全対策の検討を求めていた。
東北電によると、女川原発は約１３メートルの津波に襲われたが、海面から１４．８メートルのところに建設されていた主要施設は大きな被害を免れた。しかし、地震で敷地が１メートルほど沈んでおり、敷地から高さ３メートルの防潮堤を新たに設けて浸水を防ぐことにした。
また、原子炉の冷却機器などを動かす電源装置を高台に設置したり、原子炉建屋に水が入らないよう扉を密閉したりするという。（福島慎吾）

10/05 Onagawa N-plant restart has local mayor's support
The Yomiuri Shimbun
SENDAI--The mayor of Ishinomaki, Miyagi Prefecture, one of two municipalities that host Tohoku Electric Power Co.'s Onagawa nuclear power plant, on Monday indicated his support for the firm being given permission to resume operations at the facility.
"We need to consider restarting [the nuclear facility] after the necessary precautions have been taken," Hiroshi Kameyama said at a press conference.
His remarks came about two months after the facility was brought to an emergency halt due to the March 11 earthquake.
Kameyama became the first head of a local government to call for resumption of operations at a nuclear power plant that was shut down or brought to an emergency halt due to the disaster.
The facility straddles the border of Onagawacho and Ishinomaki, both in Miyagi Prefecture.
The Nos. 1 and 3 reactors at the plant were both in operation at the time of the March 11 disaster, and automatically shut down when the earthquake hit. The facility's No. 2 reactor was undergoing a periodical inspection at the time, and activity there was also brought to an immediate halt.
Kameyama emphasized the need to take precautions against accidents, noting a fire broke out in a switchboard inside the Onagawa facility during the March 11 disaster. However, he said the power company deserved "some credit" for its anti-tsunami measures, which he said saved the Onagawa plant from suffering a disaster comparable in scale to the ongoing crisis at Tokyo Electric Power Co.'s Fukushima No. 1 nuclear power plant.
