Input: Consent given to turn reactors at the massive Kashiwazaki-kariwa plant back on, but Japanese worry over active fault lines and mismanagement 
  
 If a single structure can define a community, for the 90,000 residents of Kashiwazaki town and the neighbouring village of Kariwa, it is the sprawling nuclear power plant that has dominated the coastal landscape for more than 40 years. 
  
  
  
 When all seven of its reactors are in operation, Kashiwazaki-kariwa generates 8.2m kilowatts of electricity – enough to power 16m households. Occupying 4.2 sq km of land along the Japan Sea coast, it is the biggest nuclear power plant in the world. 
  
 But today, the reactors at Kashiwazaki-kariwa are idle. The plant in Niigata prefecture, about 140 miles (225km) north-west of the capital, is the nuclear industry’s highest-profile casualty of the nationwide atomic shutdown that followed the March 2011 triple meltdown at Fukushima Daiichi.

 The company at the centre of the disaster has encountered anger over its failure to prevent the catastrophe, its treatment of tens of thousands of evacuated residents and its haphazard attempts to clean up its atomic mess. 
  
 Now, the same utility, Tokyo Electric Power [Tepco], is attempting to banish its Fukushima demons with a push to restart two reactors at Kashiwazaki-kariwa, one of its three nuclear plants. Only then, it says, can it generate the profits it needs to fund the decommissioning of Fukushima Daiichi and win back the public trust it lost in the wake of the meltdown. 
  
 This week, Japan’s nuclear regulation authority gave its formal approval for Tepco to restart the Kashiwazaki-kariwa’s No. 6 and 7 reactors – the same type of boiling-water reactors that suffered meltdowns at Fukushima Daiichi. 
  
 After a month of public hearings, the nuclear regulation authority concluded that Tepco was fit to run a nuclear power plant and said the two reactors met the stricter safety standards introduced after the 2011 disaster. 
  
 Just before that decision, Tepco gave the Guardian an exclusive tour of what it claims will be the safest nuclear plant in the world. 
  
  
  
 Now, as on the day of the triple disaster that brought widespread destruction to Japan’s northeast coast, Kashiwazaki-kariwa has the look of a working nuclear plant. Just over 1,000 Tepco staff and 5,000-6,000 contract workers provide the manpower behind a post-Fukushima safety retrofit that is projected to cost 680 billion yen ($6.1bn).

 They have built a 15-metre-high seawall that, according to Tepco, can withstand the biggest tsunami waves. In the event of a meltdown, special vents would keep 99.9% of released radioactive particles out of the atmosphere, and corium shields would block molten fuel from breaching the reactors’ primary containment vessels. Autocatalytic recombiners have been installed to prevent a repeat of the hydrogen explosions that rocked four of Fukushima Daiichi’s reactors. 
  
 Other parts of the sprawling complex are home to fleets of emergency vehicles, water cannon, back-up power generators, and a hilltop reservoir whose 20,000 tonnes of water will be drawn to cool reactors in the event of a catastrophic meltdown. 
  
 “As the operator responsible for the Fukushima accident, we’re committed to learning lessons, revisiting what went wrong and implementing what we learned here at Kashiwazaki-kariwa, says the plant’s chief, Chikashi Shitara. “We are always looking at ways to improve safety. 
  
 “Because of our experience at Fukushima, we’re committed to not making the same mistakes again – to make the safety regime even stronger. That’s what we have to explain to members of the public.” 
  
 ‘This is no place for a nuclear power plant’ 
  
 The public, however, is far from convinced. Last year, the people of Niigata prefecture registered their opposition to the utility’s plans by electing Ryuichi Yoneyama, an anti-nuclear candidate, as governor. Exit polls showed that 73% of voters opposed restarting the plant, with just 27% in favour. 
  
 Yoneyama has said that he won’t make a decision on the restarts, scheduled for spring 2019, until a newly formed committee has completed its report into the causes and consequences of the Fukushima disaster - a process that could take at least three years.

 For many residents, the plant’s location renders expensive safety improvements irrelevant. “Geologically speaking, this is no place for a nuclear power plant,” says Kazuyuki Takemoto, a retired local councillor and a lifelong anti-nuclear activist. 
  
 Takemoto cites instability caused by the presence of underground oil and gas deposits in the area, and evidence that the ground on which Tepco’s seawall stands is prone to liquefaction in the event of a major earthquake. 
  
 Local critics have pointed to the chaos that could result from attempting to evacuate the 420,000 people who live within a 30km radius of Kashiwazaki-kariwa. “That’s more people than lived near Fukushima, plus we get very heavy snowfall here, which would make evacuating everyone impossible,” Takemoto adds. “The situation would be far worse than it was in Fukushima.” 
  
 Adding to their concerns are the presence of seismic faults in and around the site, which sustained minor damage during a magnitude-6.6 offshore earthquake in 2007. Two active faults – defined by nuclear regulators as one that has moved any time within the last 400,000 years – run beneath reactor No. 1. 
  
 But for Tepco, a return to nuclear power generation is a matter of financial necessity, with the utility standing to gain up to ¥200 billion in annual profits by restarting the two reactors at Kashiwazaki-Kariwa.

 The bill for decommissioning Fukushima Daiichi, decontaminating neighbourhoods and compensating residents affected by the meltdown could reach 21.5tr yen [$191bn], according to government estimates. That is on top of the money the firm is spending on importing expensive fossil fuels to fill the vacuum left by the nuclear shutdown. 
  
 Earlier this year, the Japan Centre for Economic Research said the total cost of the four-decade Fukushima cleanup – including the disposal of radioactive waste from the plant’s three damaged reactors – could soar to between 50-70tr yen. 
  
 “As Tepco’s president and our general business plan have made clear, restarting the reactors here is very important to us as a company,” says Shitara. 
  
 Much is at stake, too, for Japan’s prime minister, Shinzo Abe, who has put an ambitious return to nuclear power generation at the centre of his energy policy. His government wants nuclear to provide about 20 percent Japan’s electricity by 2030 – a move that would require the restart of about 30 reactors. 
  
 Of the country’s 48 operable reactors, only four are currently online. Several others have passed stringent new safety tests introduced in the wake of Fukushima, but restarts have encountered strong local opposition. 
  
 As part of the restart process, people across Japan were recently invited to submit their opinions on the Kashiwazaki-kariwa restart and Tepco’s suitability as a nuclear operator. 
  
 Kiyoto Ishikawa, from the plant’s public relations department, insists Tepco has learned the lessons of Fukushima. “Before 3-11 we were arrogant and had stopped improving safety,” he said. “The earthquake was a wake-up call. We now know that improving safety is a continuous process.” 
  
 The firm’s assurances were dismissed by Yukiko Kondo, a Kariwa resident, who said the loss of state subsidies if the plant were to remain permanently idle was a sacrifice worth making if it meant giving local people peace of mind. 
  
 “Tepco caused the 2011 accident, so there is no way I would ever support restarting nuclear reactors here,” she said. “They kept telling us that Fukushima Daiichi was perfectly safe – and look what happened.” ||||| Two Tepco reactors were cleared for restarts by the government’s nuclear watchdog on Wednesday, becoming the first run by the operator of the crippled Fukushima power plant to formally pass stricter safety standards imposed after the 2011 crisis. 
  
 The Nuclear Regulation Authority on Wednesday endorsed safety measures for the Nos. 6 and 7 reactors at Tokyo Electric Power Company Holdings Inc.’s Kashiwazaki-Kariwa power station in Niigata Prefecture. The move was announced at a meeting that was open to the public, with some members of the audience shouting their disapproval. 
  
 Despite Wednesday’s development, the process of reactivating the reactors straddling the municipalities of Kashiwazaki and Kariwa in Niigata on the Sea of Japan coast could still take several more years as local governments need to give their consent. 
  
 Niigata Gov. Ryuichi Yoneyama, who has said it will take “at least three to four years” before he can decide on whether to approve the restart of the reactors, issued a statement saying he wants to be briefed on the plan and “examine the outcome of the review.” 
  
 The two units are boiling-water reactors, the same as those that suffered meltdowns in the Fukushima crisis caused by the massive earthquake and tsunami in March 2011. No such reactor types had previously cleared the nation’s tougher safety standards introduced after the disaster, partly because major refurbishment is required to meet the new regulations. 
  
 The watchdog’s approval of the two units brings the total number of reactors that have cleared the post-crisis safety regulations to 14, with the government pushing to restart nuclear plants that were taken offline after the crisis at the Fukushima No. 1 complex, the world’s worst nuclear disaster since Chernobyl in 1986. 
  
 In addition to assessing technical requirements, the review by the NRA focused on whether Tepco is qualified to operate a nuclear power plant as it struggles with the scrapping of the Fukushima No. 1 complex — an effort expected to take until around 2051 — and in dealing with contaminated water around the crippled plant where radiation levels remain high. 
  
 Of around 800 public comments received by the regulator regarding its assessment of the Tepco reactors, about half questioned Tepco’s qualification to run nuclear plants. 
  
 At Wednesday’s meeting, some members of the public voiced opposition, with one person saying, “It is not a technical or scientific assessment, but a political one.” 
  
 In front of the building housing the NRA in Tokyo, civic group members gathered to protest the approval. 
  
 “Tepco has no technical qualifications to run a nuclear power plant after causing such an accident,” said Yoshinari Usui, a former public official from Kawasaki. “The restart of the Kashiwazaki-Kariwa units is totally unacceptable.” 
  
 Han Kumata, a 37-year-old from Tokyo, said, “I have absolutely no trust in Tepco even if it says it has implemented safety measures.” 
  
 As a condition for gaining safety clearance, Tepco agreed to a request from the regulator to provide a safety pledge in its legally binding plant operation program. 
  
 The NRA says it can continue to monitor Tepco by conducting inspections and order the halt of operations if it finds any safety violations. 
  
 Facing huge compensation payments and other costs stemming from the Fukushima crisis, Tepco has been trying to resume operation of its reactors to reduce dependence on costly fossil fuel imports for non-nuclear thermal power generation. 
  
 In Niigata, not all residents oppose nuclear power, given its economic benefits. 
  
 “There may be risks, but the local (municipality) cannot stand without nuclear power. I want the reactors to be restarted if they have been deemed safe,” said Kashiwazaki resident Toru Murata, who works in the construction industry. 
  
 But Mie Kuwabara, a 69-year-old resident of the city of Niigata, expressed concern about the reactors coming back online, saying, “I think the possibility of a serious accident still remains,” considering past problems at the plant — including insufficient quake resistance of a building to be used as an emergency headquarters. 
  
 The two reactors are the newest among the seven units at the Kashiwazaki-Kariwa facility. The complex is one of the world’s largest nuclear power plants, with a combined output capacity of 8.2 million kilowatts. 
  
 Tepco filed for safety assessments of the two reactors in September 2013. |||||
Output:
The biggest nuclear power plant in the world sits idle, as it has for nearly seven years. But that state is set to change, and not without public trepidation. The Guardian reports that Japan's nuclear watchdog this week gave Tokyo Electric Power (TEPCO) the green light to restart two of the seven reactors at Kashiwazaki-kariwa, which fell victim to the country's nuclear power moratorium in the wake of the March 2011 Fukushima disaster. That calamity occurred on TEPCO's watch, and the utility says the money it will generate from Kashiwazaki-kariwa's power is key to funding its continuing decommissioning efforts at Fukushima. It has poured more than $6 billion into Kashiwazaki-kariwa in an effort to make it immune to the series of disasters that befell Fukushima. A 50-foot seawall provides tsunami protection, for instance, and 22,000 tons of water sit in a nearby reservoir, ready for the taking if reactors need sudden cooling. But locals aren't convinced—the Japan Times reports some people shouted at the meeting where the restart approval was granted—and that matters: Though the restarts are penciled in to occur in spring 2019, the AFP reports local authorities need to give their OK, and that process could take years. The plant is located in Niigata prefecture, and locals there cite the active seismic faults in the area as a major concern; the Guardian notes "evidence that the ground on which Tepco's seawall stands is prone to liquefaction in the event of a major earthquake." A second is the fear that should an evacuation be necessary, it would be much less successful than that of Fukushima due to the bigger population.
