Almost two years after a deadly tsunami crashed into the Fukushima Dai-ichi nuclear power plant, crippling its backup power supply and triggering the world’s worst nuclear crisis for a quarter of a century, the gravest danger has passed.
However, on a rare trip to the atomic facility, for all the signs of progress since I last visited a year ago the most complex nuclear decommissioning operation ever carried out has barely begun.
Radiation levels in the abandoned communities near the power plant have fallen 40 percent in the past year. Inside the wrecked facility, construction workers rush to complete state-of-the-art equipment that will remove dozens of dangerous radioactive nuclides from cooling water. Soon, a steel shield will be driven into the seabed to prevent contamination from the plant from leaking into the Pacific.
The pipes, cables and other equipment strewn across the plant’s grounds this time last year are now functioning components in a complex, technologically fraught mission to cool the crippled reactors, while experts struggle to figure out how to extract the melted nuclear fuel lying deep inside their basements.
The three reactors struck by meltdown and hydrogen explosions two years ago were brought to a safe state known as “cold shutdown” in December 2011, nine months after the tsunami left almost 20,000 dead or missing along Japan’s northeast coast.
Now, Japan is about to embark on a cleanup that could cost at least US$100 billion — on top of the cost of compensating evacuees and decontaminating their abandoned homes.
Fukushima Dai-ichi’s manager, Takeshi Takahashi, conceded that decommissioning the plant could take between 30 and 40 years.
“Even though we are still faced with a difficult task, we’ll keep pushing on with the decommissioning process,” he told a small group of visiting foreign journalists on Wednesday. “It will take a long time to complete our work, especially on the three reactors that suffered meltdown, but we’ll do our best to keep them stable.”
The cleanup operation will begin at reactor No 4, where the fuel rods inside survived unscathed after it was hit by the tsunami, then badly damaged by a hydrogen explosion.
By the end of this year Tokyo Electric Power Co (TEPCO) says it will begin removing fuel assemblies from the reactor and placing them in a nearby cooling pool, where they will remain for four years before being stored in dry casks in a purpose-built facility on higher ground.
In total, workers will have to extract more than 11,000 new and used fuel assemblies from seven badly damaged storage pools. Work to remove melted fuel will not begin until 2021, and the entire decommissioning project is expected to take up to 40 years.
Managers from firms contracted by TEPCO to help decommission the 40-year-old plant say they are confident progress is being made, despite the radiation hazards faced by their employees.
Perhaps the most dangerous job on the site has fallen to Hiroshige Kobayashi and his colleagues. As a manager at Kajima Corp, Kobayashi is responsible for clearing and processing the rubble and debris from reactor No. 3, where radiation levels easily outstrip those at other parts of the site.
The dangers associated with working in highly radioactive areas of Fukushima Dai-ichi prompted the WHO to warn last week that one-third of the plant’s workers face an increased risk of developing thyroid cancer, leukemia and all solid cancers during their lifetimes.
Kobayashi declined to comment on the WHO report, but acknowledged that workers face unprecedented danger from persistently high radiation levels.
Several strong quakes have shaken northeast Japan since March 11, 2011, but Takahashi insisted the reactor No. 4 building — where 1,500 fuel assemblies stored in a pool on the top floor have drawn concern because of their vulnerability to seismic activity — could withstand an earthquake of similar intensity to the one that destroyed the plant two years ago.
Despite those reassurances, Takahashi conceded the plant has become the focal point of a nuclear crisis whose victims, like the facility itself, are a long way from returning to any semblance of normality.
On the drive through the 20km evacuation zone to Fukushima Dai-ichi, visitors pass entire villages that remain frozen in time. Half a dozen cars sit abandoned in a supermarket car park, shops and restaurants lie deserted, and thousands of black bags filled with contaminated soil and grass cover fields once used to grow rice, while authorities decide how, and where, to dispose of them.
Meanwhile, the tens of thousands of residents who once called this forbidding landscape home still have no idea when, or if, they will be able to return.
Because much of what former US president Donald Trump says is unhinged and histrionic, it is tempting to dismiss all of it as bunk. Yet the potential future president has a populist knack for sounding alarums that resonate with the zeitgeist — for example, with growing anxiety about World War III and nuclear Armageddon. “We’re a failing nation,” Trump ranted during his US presidential debate against US Vice President Kamala Harris in one particularly meandering answer (the one that also recycled urban myths about immigrants eating cats). “And what, what’s going on here, you’re going to end up in World War
Earlier this month in Newsweek, President William Lai (賴清德) challenged the People’s Republic of China (PRC) to retake the territories lost to Russia in the 19th century rather than invade Taiwan. He stated: “If it is for the sake of territorial integrity, why doesn’t [the PRC] take back the lands occupied by Russia that were signed over in the treaty of Aigun?” This was a brilliant political move to finally state openly what many Chinese in both China and Taiwan have long been thinking about the lost territories in the Russian far east: The Russian far east should be “theirs.” Granted, Lai issued
On Tuesday, President William Lai (賴清德) met with a delegation from the Hoover Institution, a think tank based at Stanford University in California, to discuss strengthening US-Taiwan relations and enhancing peace and stability in the region. The delegation was led by James Ellis Jr, co-chair of the institution’s Taiwan in the Indo-Pacific Region project and former commander of the US Strategic Command. It also included former Australian minister for foreign affairs Marise Payne, influential US academics and other former policymakers. Think tank diplomacy is an important component of Taiwan’s efforts to maintain high-level dialogue with other nations with which it does
On Sept. 2, Elbridge Colby, former deputy assistant secretary of defense for strategy and force development, wrote an article for the Wall Street Journal called “The US and Taiwan Must Change Course” that defends his position that the US and Taiwan are not doing enough to deter the People’s Republic of China (PRC) from taking Taiwan. Colby is correct, of course: the US and Taiwan need to do a lot more or the PRC will invade Taiwan like Russia did against Ukraine. The US and Taiwan have failed to prepare properly to deter war. The blame must fall on politicians and policymakers
