Japan's nuclear watchdog halts plant's reactor safety screening over falsified data

TOKYO (AP) — Japan's nuclear watchdog said Wednesday it is scrapping the safety screening for two reactors at the Hamaoka nuclear power plant in central Japan, after its operator was found to have fabricated data about earthquake risks.

It was a setback to Japan's attempts to accelerate nucler reactor restarts. Less than a quarter of commercial nuclear reactors are operational in the wake of the 2011 Fukushima Daiichi meltdowns, but rising energy costs and pressure to reduce carbon emissions have pushed the government to prioritize nuclear power.

Chubu Electric Power Co. had applied for safety screening to resume operations at the No. 3 and 4 reactors at the Hamaoka plant in 2014 and 2015. Two other reactors at the plant are being decommissioned, and a fifth is idle.

The plant, about 200 kilometers (125 miles) west of Tokyo, is located on a coastal area known for potential risks from so-called Nankai Trough megaquakes.

The Nuclear Regulation Authority said it started an internal investigation last February, after receiving a tip from a whistleblower that the utility had for years provided fabricated data that underestimated potential seismic risks.

The regulator suspended the screening for the reactors after it confirmed the falsification and the utility acknowledged the fabrication in mid-December, said Shinsuke Yamanaka, the watchdog's chair. The NRA is also considering inspecting the utility headquarters.

“Ensuring safety is the first and foremost responsibility for nuclear plant operators," Yamanaka said, adding that seismic data was clearly fabricated. “It is outrageous and it's a serious challenge to safety regulation.”

The scandal surfaced Monday when Chubu Electric President Kingo Hayashi acknowledged that workers at the utility used inappropriate seismic data with an alleged intention to underestimate seismic risks. He apologized and pledged to establish an independent panel for investigation.

The screening, including data that had been approved earlier, would have to start from scratch or possibly be rejected entirely, Yamanaka said. The NRA will decide on the case next week, without waiting for the utility's probe results, he said.

Public opinion in Japan remains divided due to lingering safety concerns after the 2011 Fukushima Daiichi meltdowns.

Of Japan's 57 commercial reactors, 13 are currently in operation, 20 are offline and 24 others are being decommissioned, according to NRA.

A former Ohio music pastor who once appeared on “American Idol” was convicted of murder Tuesday in the killing of his wife while he was having an affair.

Prosecutors said Caleb Flynn, 40, staged a home invasion in February after shooting his wife, Ashley Flynn, a 37-year-old schoolteacher and volleyball coach.

Flynn, who claimed his wife was killed by a burglar, could now be sentenced to life in prison without the chance of parole. He closed his eyes, shook his head to the side and fought to maintain his composure as the judge read the guilty verdicts to murder, felonious assault and tampering with evidence.

Flynn appeared on “American Idol” in 2013, telling TV viewers about how his wife had encouraged him to chase his dreams on the singing competition. He sang before judges Mariah Carey, Randy Jackson and Nicki Minaj but did not advance to the main competition in Hollywood.

Prosecutors told jurors during closing arguments Tuesday that Flynn wanted out of his marriage when he shot his wife at their home in Tipp City, a suburb north of Dayton. Flynn and the couple’s two daughters were home when police arrived.

Flynn also didn’t want to lose his daughters, his high-paying job at his wife’s family business or his position in the church, prosecutors said.

“He wanted to keep his mistress and have his daughters all to himself,” said Matthew Joseph, an assistant Miami County prosecutor.

During the trial, a woman who said she was having an affair with Flynn testified that he said he hated his wife and had thoughts of killing her.

Flynn’s attorney told the jury Tuesday that investigators never found a gun or evidence that Flynn fired a gun that day.

“His being unfaithful doesn’t equal murder,” said defense attorney Patrick Mulligan. “The issue here isn’t, ‘Was he a good husband?’”

Text messages Flynn sent to his lover complaining about his wife were meant to make her feel good, Mulligan said.

Alleigha Botner testified she met Flynn in 2022 while she was a 20-year-old intern at his church and had an affair with him for more than a year. Botner read some of her text messages with Flynn.

About six months before the killing, Flynn wrote: “I was up until 4 a.m. last night crying, literally trying to think of ways to kill her and not go to jail.”
