Additionally, the Toshiba 4S utilizes liquid sodium as a coolant, allowing the reactor to operate 200 degrees hotter than if it used water. [ clarification needed ] Although water would readily boil at these temperatures, sodium remains a liquid; the sodium coolant therefore exerts very low pressure on the reactor vessel even at extremely high ...
Toshiba manufactured four of the six reactors the Fukushima Daiichi nuclear power plant in the 1970s. [2] He rose to public prominence on 14 March 2011 by being the first "insider" (Note: he retired from Toshiba in 2009 [2]) addressing the press at the Foreign Correspondents' Club of Japan, three days after the Fukushima Daiichi nuclear disaster.
Slightly different versions of the ABWR are offered by GE-Hitachi, Hitachi-GE, and Toshiba.

In October 2010, the South Texas Project announced that the Tokyo Electric Power Company (TEPCO) had entered into an agreement with Nuclear Innovation North America (a joint venture between the reactor manufacturer, Toshiba, and plant partner NRG Energy) which was the largest of the two stakeholders in the proposed reactors, to purchase an ...
It was the most quickly constructed nuclear power plant in the world. [citation needed] All the reactors were constructed by Toshiba. [2] The Onagawa-3 unit was used as a prototype for the Higashidori Nuclear Power Plant. [3] The plant had been shut down after the 2011 Tōhoku earthquake and tsunami.

On 28 December 1970 Toshiba began the construction of unit 3 of the Fukushima Daiichi Nuclear Power Plant [144] which was damaged in the Fukushima I nuclear accidents on 14 March 2011. In April 2011, CEO Norio Sasaki declared nuclear energy would "remain as a strong option" even after the Fukushima I nuclear accidents.
