Kyushu Electric Power Co.’s restart of Sendai 1—the first Japanese reactor to begin operation under new safety standards after the Fukushima disaster—hit a technical hiccup last week, prompting the company to halt ramp up of power output. The utility said on Aug. 21 that it had suspended increasing output at the unit after an alarm […]

Nearly two years after Japan’s last nuclear power plant was shut down for safety checks, Kyushu Electric Power Co. has started up the 890-MW Sendai-1. The event marks a significant milestone for the country’s nuclear sector, which was crippled by the Fukushima disaster in 2011.  Kyushu started up Sendai-1 at 10:30 a.m. local time and […]

The International Energy Agency predicts that nearly 200 reactors will be decommissioned during the next 25 years. Industry best practices and new technology can help make the process go more smoothly. It may not come as a surprise, but the average age of operating reactors in the U.S. is greater than 35 years. There hasn’t […]

Southern Co. announced on June 16 that construction has been completed on a new FLEX dome—a structure built to house emergency equipment needed to respond to an extreme external event—at its Vogtle nuclear plant. The Nuclear Regulatory Commission (NRC) is requiring U.S. nuclear plants to build protected structures like the FLEX dome in response to […]

A Japanese court has rejected a petition to halt the restart of two reactors at the Sendai nuclear power plant, putting the country on course again to revive its long-stalled nuclear power sector.  The Kagoshima district court in southwest Japan rejected claims by residents that nearby volcanoes pose risks to the Sendai plant, and that […]

The chairman and ranking member of the U.S. Senate Committee on Environment and Public Works (EPW) presented conflicting progress reports on the status of Fukushima task force recommendations during a committee oversight hearing held on April 15. “You haven’t done really anything since Fukushima, as far as I can tell,” said Sen. Barbara Boxer (D-Calif.), […]

A Japanese court has blocked plans to reopen two reactors that had been previously cleared to resume operations by the Nuclear Regulation Authority (NRA).  Local residents in western Japan’s Fukui Prefecture, where Kansai Electric Power Co.’s Takahama nuclear plant is located, successfully petitioned a court to issue an injunction halting plans to restart Units 3 […]

Four years after the massive earthquake and ensuing tsunami heavily damaged the Fukushima Daiichi nuclear plant in Japan, cleanup efforts continue amid new challenges, while Japan has made little progress on the policy front. The Ongoing Crisis at Daiichi By the fourth anniversary of the devastating events at Fukushima, the situation onsite has improved markedly, […]

March 11 marked the third anniversary of the magnitude 9.0 earthquake and subsequent tsunami that struck the east coast of Japan. Within days of that event, with no backup power, cooling systems failed at Tokyo Electric Power Co.’s (TEPCO’s) Fukushima Daiichi plant, leading to meltdowns and hydrogen explosions at Units 1, 2, and 3.  But […]

Tokyo Electric Power Co. (TEPCO) today began the delicate process of removing spent fuel from Unit 4 of the crippled Fukushima Daiichi nuclear plant. The six-unit site has two reactor groups, comprising Units 1–4 and Units 5 and 6. Unit 4 is the only reactor of its group that did not suffer a meltdown following […]
