again has a working nuclear reactor as the number 3 reactor at the Ohi nuclear plant begins generating power. This is the first reactor to be restarted since the tsunami, and marks the end of two months without nuclear power for Japan. 12 October TEPCO admits for the first time that it had failed to take stronger measures to prevent disasters for fear of inviting lawsuits or protests against its nuclear plants. TEPCO's internal reform task force, led by company President Naomi Hirose, said in a report TEPCO had feared efforts to better protect nuclear facilities from severe accidents such as tsunamis would trigger anti-nuclear sentiment, interfere with operations or increase litigation risks. TEPCO could have mitigated the impact of the accident if it had diversified power and cooling systems by paying closer attention to international standards and recommendations, the report said. TEPCO also should have trained employees with practical crisis management skills rather than conduct obligatory drills as a formality, it said. In the internal report TEPCO said that before the accident it had been afraid to consider the risk of such a large tsunami as the one in March 2011 which hit Fukushima, fearing admissions of risk could result in public pressure to shut plants down. "There were concerns that if new countermeasures against severe accidents were installed, concern would spread in host communities that the current plants had safety problems," the report said. TEPCO said in the report that "severe accident measures" were taken in 2002, which included "containment venting and power supply cross-ties between units," but additional measures were never put in place. TEPCO added that taking such measures could also add to "public anxiety and add momentum to anti-nuclear movements." 2013 18 March Public trust in TEPCO takes another hit as cooling systems for several spent-fuel pools go down for more than 29 hours after a power interruption that may have been caused by a rat in a switchboard. 9 July Levels of caesium in groundwater from monitoring wells around the reactors jumps by 90 times compared with the levels 3 days earlier. The contamination is now measured at 9,000 becquerels of caesium-134 and 18,000 becquerels of caesium-137 per litre of water. As well, tritium levels in seawater from the port next to the plant have been increasing since May, and a water sample taken on 3 July showed 2,300 becquerels per litre, the highest
