TOKYO (AP) — A remote-controlled robot has safely returned with a tiny piece of melted fuel it collected from inside one of three damaged reactors at the tsunami-hit Fukushima Daiichi nuclear power plant for the first time since the 2011 meltdown.
The Tokyo Electric Power Company Holdings, which manages the plant, said Saturday that the extendable fishing rod-like robot successfully clipped a piece of gravel of about 5 millimeters (0.2 inches), the size of a tiny bit of granola, from the top surface of a mound of molten fuel debris that sits on the bottom of the No. 2 reactor’s primary containment vessel.
The “telesco” robot, with its frontal tongs still holding the melted fuel bit, returned to the enclosed container for safe storage after workers in full hazmat gear pulled it out of the containment vessel earlier Saturday.
The sample return marks the first time the melted fuel is retrieved out of the containment vessel. But the mission is not over until it's certain that the sample's radioactivity is below a set standard and safely placed into a container.
If the radioactivity exceeds the limit, the robot must go back inside the reactor to find another piece. TEPCO officials said they expect the piece is small enough to meet the requirement.
The mission initially started in August for what was supposed to be a two-week round trip but had been suspended twice due to mishaps.
First one was the procedural mistake at the beginning that held up the work for nearly three weeks, then the robot’s two cameras designed to transmit views of the target areas for its operators in the remote control room failed. The camera problem required the robot to be pulled out all the way for replacement before the mission resumed Monday.
Fukushima Daiichi lost its key cooling systems during the 2011 earthquake and tsunami, causing meltdowns in its three reactors. An estimated 880 tons of fatally radioactive molten fuel remains in them, and TEPCO has carried out a number of robotic probes to figure out how to decommission the plant.
Telesco on Wednesday successfully clipped a piece presumably measuring less than 3 grams (0.1 ounce) from the planned area right underneath the Unit 2 reactor core, from which large amounts of melted fuel fell during the meltdown 13 years ago, TEPCO said.
Plant chief Akira Ono said only the tiny spec can provide key data to plan decommissioning strategy, develop necessary technology and robots and retroactively learn how the accident had developed.
The government and TEPCO have set a 30-to-40-year target for the cleanup, which experts say is overly optimistic and should be updated.
No specific plans for the full removal of the fuel debris or its final disposal have been decided.

WASHINGTON (AP) — A Navy admiral commanding the U.S. military strikes on an alleged drug boat in the Caribbean told lawmakers Thursday that there was no “kill them all” order from Defense Secretary Pete Hegseth, but a stark video of the attack left grave questions as Congress scrutinizes the campaign that killed two survivors.
Adm. Frank “Mitch” Bradley appeared for a series of closed-door classified briefings at the Capitol as lawmakers conduct an investigation after a report that he ordered the follow-on attack that killed the survivors to comply with Hegesth’s demands. Legal experts have said such a strike could be a violation of the laws of military warfare.
“Bradley was very clear that he was given no such order, to give no quarter or to kill them all,” said Sen. Tom Cotton, who heads the Senate Intelligence Committee, as he exited a classified briefing.
While Cotton, R-Ark., defended the attack, Democrats who were also briefed and saw video of the survivors being killed questioned the Trump administration’s rationale and said the incident was deeply concerning.
“The order was basically: Destroy the drugs, kill the 11 people on the boat,” said Washington Rep. Adam Smith, the top Democrat on the House Armed Services Committee.
Smith, who is demanding further investigation, said the survivors were “basically two shirtless people clinging to the bow of a capsized and inoperable boat, drifting in the water — until the missiles come and kill them.”
The classified sessions with Bradley, alongside the chairman of the Joint Chiefs of Staff Gen. Dan Caine, provided fresh information at a crucial moment as Hegseth's leadership comes under scrutiny. But they did little to resolve growing questions about the legal basis for President Donald Trump's extraordinary campaign to use war powers against suspected drug smugglers. So far more than 80 people have been killed in some 20 strikes.
Late Thursday, U.S. Southern Command announced it had conducted another strike against a small boat in the eastern Pacific Ocean following a pause of almost three weeks. There were four casualties, according to the social media post.
Lawmakers have not yet specifically authorized the use of military force against the alleged drug boats, and the Republican-controlled Congress has turned back attempts to put a check on Trump’s power to engage in the missile campaign, which Hegseth has vowed will continue. Several Democrats have called for Hegseth to resign.
Lawmakers want a full accounting of the Sept. 2 strike, which was the first in what has become a monthslong series of U.S. military attacks on vessels near Venezuela believed to be ferrying drugs. The Washington Post had reported that Bradley ordered the follow-on attack on the survivors.
But lawmakers who lead the House and Senate's national security committees in Congress came away with different descriptions of what the two survivors were doing when they were killed.
Cotton said he saw them "trying to flip a boat loaded with drugs bound for United States back over so they could stay in the fight.”
He said there were “several minutes” between the first and second attacks, which consisted of four missile strikes. He said it was “gratifying” that the U.S. military was taking “the battle” to cartels.
But Connecticut Rep. Jim Himes, the top Democrat on the House Intelligence Committee, said, “what I saw in that room was one of the most troubling things I've seen in my time in public service.”
“You have two individuals in clear distress, without any means of locomotion, with a destroyed vessel," he said, and who "were killed by the United States."
The survivors did not issue any distress call or other communications, though lawmakers were told it appeared the people had a hand raised, “waving” at one point during the attacks, Smith said.
Smith acknowledged there was likely cocaine on the boat, but he objects to the Republican administration’s rationale for continued attacks on alleged drug runners who may or may not be heading to the United States. “That’s really the core of the problem with all of this,” he said. “That incredibly broad definition, I think, is what sets in motion all of these problems about using lethal force and using the military.”
At the time of the attack, Bradley was the commander of Joint Special Operations Command, overseeing coordinated operations between the military's elite special operations units out of Fort Bragg in North Carolina. About a month after the strike, he was promoted to commander of U.S. Special Operations Command.
His military career, spanning more than three decades, was mostly spent serving in the elite Navy SEALs and commanding joint operations. He was among the first special forces officers to deploy to Afghanistan after the Sept. 11 attacks. His latest promotion to admiral was approved by unanimous voice vote in the Senate this year, and Democratic and Republican senators praised his record.
Sen. Thom Tillis, R-N.C., has described Bradley as among those who are “rock solid” and “the most extraordinary people that have ever served in the military.”
But lawmakers like Tillis have also made it clear they expect a reckoning if it is found that survivors were targeted. “Anybody in the chain of command that was responsible for it, that had vision of it, needs to be held accountable,” he said.
Underpinning Trump’s campaign against suspected traffickers is his argument that drug cartels amount to armed combatants because their cargo poses a threat to American lives.
Democrats are demanding the release of the full video of the Sept. 2 attack, as well as written records of the orders and any directives about the mission from Hegseth. None of the written orders or audio of verbal commands was shared with the lawmakers.
A White House Office of Legal Counsel memo providing a rationale for the strikes was dated after the fact, on Sept. 5. That memo remains undisclosed, and Democrats want it released.
Obtaining further information, though, will largely depend on action from Republican lawmakers, who have majority control of the committees, a potentially painful prospect for them if it puts them at odds with the president.
Rhode Island Sen. Jack Reed, the top Democrat on the Armed Services Committee, said that he and the Senate Armed Services Committee chair, GOP Sen. Roger Wicker, have formally requested the executive orders authorizing the operations and the complete videos from the strikes, among other items. The Trump administration has repeatedly denied their requests for basic information about the operation, Reed said.
Republican lawmakers who are close to Trump have largely stood by Hegseth and the administration's decision to conduct the strikes.
Elsewhere, Venezuelan President Nicolás Maduro and others see the U.S. military operation as part of an effort to prompt a government change in the South American country. Maduro on Wednesday acknowledged speaking last month by phone with Trump, who confirmed the call days earlier.
