VOX POPULI: Fukushima debris removal is a task that will likely take eons
Buddhism uses its own unique units to express vast spans of time and numbers.
Imagine a colossal castle, seven kilometers long, wide, and tall, its interior completely filled with poppy seeds. Once every hundred years, a single seed is removed.
The time it would take to empty the castle—removing one seed every century until none remain—would still be shorter than what Buddhism calls a kalpa, or 'ko' in Japanese.
Often translated as an eon, a ko represents an unfathomably long stretch of time, used to convey the sense of an almost inconceivable duration.
The term also appears in the expression 'mirai eigo,' meaning 'an eternal future' or 'for all eternity,' evoking something that continues without end.
How long, then, will it take to remove the fuel debris from the Fukushima No. 1 nuclear power plant, which suffered triple meltdowns in the 2011 disaster?
The debris—which was once nuclear fuel that overheated, melted and fused with structural materials inside the reactors—was originally scheduled for removal beginning in 2021.
Yet immense technical challenges delayed the start until last year.
Tokyo Electric Power Co., the plant's operator, recently announced that full-scale debris removal for reactor No. 3 will begin in fiscal 2037 or later.
For reactors No. 1 and No. 2, no timeline has even been set.
Of an estimated 880 tons of debris, only 0.9 gram has been recovered to date. A simple calculation based on the time since the accident suggests the removal process could take another 13.6 billion years to complete.
Critics rightly argue that such an estimate is absurdly simplistic and misleading. But then, what would a realistic projection look like?
Despite knowing full well the near impossibility of the task, authorities and TEPCO continue to uphold the goal of 'completing reactor decommissioning by 2051'—a timeline that seems more like sleight of hand than sincere policy, meant to lull the public into a false sense of reassurance.
Even as Japan struggles to dismantle the legacy of Fukushima, the nation has pivoted boldly toward the 'maximum use' of nuclear energy. Kansai Electric Power Co. is now preparing to construct an entirely new plant.
Has the landscape really shifted so dramatically—can a country's stance reverse so completely—in just the 14 years since the Great East Japan Earthquake?
There's a word for something that defies belief: 'fukashigi.' Bizarre, inconceivable.
Fittingly, this term too originated as a unit of measure in Buddhist cosmology—used to signify numbers so vast they dwell beyond comprehension.

Astronauts launch to the space station after sidelined by Boeing's troubled Starliner
Astronaut Kimiya Yui, of Japan gestures as he leaves the Operations and Checkout Building for a trip the Kennedy Space Center's Launch Pad 39-A and a planned liftoff on a SpaceX Falcon 9 rocket on Aug. 1 in Cape Canaveral, Fla. (AP Photo) CAPE CANAVERAL, Fla.--Astronauts sidelined for the past year by Boeing's Starliner trouble blasted off to the International Space Station on Friday, getting a lift from SpaceX. The U.S.-Japanese-Russian crew of four rocketed from NASA's Kennedy Space Center. They'll replace colleagues who launched to the space station in March as fill-ins for NASA's two stuck astronauts. Their SpaceX capsule should reach the orbiting lab this weekend and stay for at least six months. Zena Cardman, a biologist and polar explorer who should have launched last year, was yanked along with another NASA crewmate to make room for Starliner's star-crossed test pilots. 'I have no emotion but joy right now. That was absolutely transcendent. Ride of a lifetime,' Cardman, the flight commander, said after reaching orbit. The botched Starliner demo forced Butch Wilmore and Suni Williams to switch to SpaceX to get back from the space station more than nine months after departing on what should have been a weeklong trip. 'Every astronaut wants to be in space. None of us want to stay on the ground, but it's not about me,' Cardman said before her flight. NASA's Mike Fincke — Cardman's co-pilot — was the backup for Wilmore and Williams on Starliner, making those three still the only ones certified to fly it. Fincke and Japan's Kimiya Yui, former military officers with previous spaceflight experience, were training for Starliner's second astronaut mission. With Starliner grounded until 2026, NASA switched the two to the latest SpaceX flight. 'Boy, it's great to be back in orbit again,' Fincke radioed. He last soared on NASA's next-to-last space shuttle flight in 2011. Rounding out the crew is Russia's Oleg Platonov. The former fighter pilot was pulled a few years ago from the Russian Soyuz flight lineup because of an undisclosed health issue that he said has since been resolved. On hand for the first launch attempt on Thursday, NASA's new acting administrator, Transportation Secretary Sean Duffy, met with Roscosmos director general Dmitry Bakanov, an invited guest. The two discussed future collaboration, then left town after thick clouds forced a last-minute delay. 'What we learn on these missions is what's going to get us to the moon and then from the moon to Mars, which is I think the direction that NASA has to be,' Duffy said in a NASA interview. 'There's critical real estate on the moon. We want to claim that real estate for ourselves and our partners.' To save money in light of tight budgets, NASA is looking to increase its space station stays from six months to eight months, a move already adopted by Russia's space agency. SpaceX is close to certifying its Dragon capsules for longer flights, which means the newly launched crew could be up there until April. NASA is also considering smaller crews — three astronauts launching on SpaceX instead of the typical four — to cut costs. As for Starliner, NASA is leaning toward launching the next one with cargo before flying another crew. Engineers are still investigating the thruster failures and helium leaks that bedeviled Starliner following liftoff. Time is running out as NASA looks to abandon the aging space station by 2030. An air leak on the Russian side of the station remains unresolved after years of patching. Engineering teams already are working on the plan for the space station's last days. NASA's Ken Bowersox said the U.S. and Russia need to cooperate in order to steer the outpost into the Pacific with minimal risk to the public. It will take at least two years to get the space station low enough to where a SpaceX vehicle can provide the final shove. Thrusters on the Russian side of the station will help with control, but that means more fuel will have to be delivered by 2028. The latest timeline calls for SpaceX to launch the last mission for NASA — the deorbit vehicle — to the space station in 2029. Astronauts would remain on board until the last four to six months of the station's life to handle any breakdowns, with the empty outpost plunging into the Pacific by late 2030 or early 2031.

Japan astronaut Yui heads to ISS on SpaceX craft on 2nd space mission
CAPE CANAVERAL, Florida (Kyodo) -- A team of astronauts from Japan, Russia and the United States headed to the International Space Station aboard a SpaceX craft from Florida on Friday, marking the second space flight for Japanese astronaut Kimiya Yui. The Crew-11 mission, also involving two Americans and one Russian, will stay at the ISS for about six months, partly to conduct experiments in hopes of helping future lunar exploration. It is expected to reach the ISS in the early hours of Saturday. "My fellow Japanese out there, I have come back to space for the first time in 10 years," Yui said in Japanese from inside the Crew Dragon capsule after it separated from the booster rocket. "I'm resolved to perform my duties well, shine like a star of the first magnitude and let people all over the world know great things about Japan." Yui, a 55-year-old Nagano Prefecture native and former Air Self-Defense Force pilot, previously stayed at the ISS between July and December 2015, and was responsible for the docking of an unmanned supply craft developed by Japan. Japan's Takuya Onishi, in command of the International Space Station since April, is due to return to Earth following a handover period of several days. The 49-year-old former airline pilot is the third Japanese astronaut to have served as ISS commander. The Crew-11 mission comprises Yui of the Japan Aerospace Exploration Agency, Zena Cardman and Mike Fincke of the National Aeronautics and Space Administration, as well as Roscosmos cosmonaut Oleg Platonov. Among other things, Yui will participate in a test of carbon dioxide removal technology necessary for Gateway, a space station that will orbit the Moon under the U.S.-led Artemis lunar exploration program.
