Plant Status

  • Tokyo Electric Power Co. continues its attempts to decontaminate radioactive water that has collected in the basements of buildings and in drains at the Fukushima Daiichi nuclear energy facility. With its current decontamination system operating at only 53 percent of capacity, TEPCO is planning to receive new water treatment equipment this week.  TEPCO will use the new system alongside the existing one.

  • After a 6.2 magnitude earthquake struck offshore from Fukushima in the early hours of July 25, Tokyo Electric Power Co. reported there were no problems with any of the systems used to stabilize the reactors at Fukushima Daiichi and no injuries. TEPCO checked the systems for water and nitrogen injection into reactors 1, 2 and 3, the water treatment facility, and the used fuel pool cooling systems for reactors 2 and 3. Read More »

  • Japanese media are reporting on a joint assessment by Tokyo Electric Power Co. and the government that the company has met the first step in its effort to stabilize the reactors at the Fukushima Daiichi site. Among the targets met in the first step include re-establishing stable cooling capacity for reactors 1-3 and the used fuel storage pools for reactors 1-4. The company says it did this by putting recirculating cooling water systems into operation. A key indicator of success, TEPCO says, is that temperatures at the bottom of the reactor pressure vessels have decreased and are now stable. TEPCO also says it has reduced the level of radioactive releases from the plant to one-2 millionth of the peak release recorded just after the March accident. Read More »

  • Tokyo Electric Power Co. expects to meet its self-imposed July 19 deadline to stabilize reactor cooling and mitigate radiation at the Fukushima Daiichi nuclear energy facility. That work includes injecting inert nitrogen gas into the reactor 3 containment vessel, which started today. The nitrogen is intended to help prevent a potential explosion of built-up hydrogen. TEPCO has been injecting nitrogen into reactors 1 and 2 since April 7 and June 28 respectively. The next major milestone in the plan for Fukushima recovery includes cold shutdowns for reactors 1-3, which are expected to take place in the next three to six months.

  • Tony Pietrangelo, NEI’s senior vice president and chief nuclear officer, conducted a teleconference with the media today on the U.S. Nuclear Regulatory Commission staff report recommending steps the agency should take in light of the accident at Fukushima Daiichi. Earlier in the day, Pietrangelo appeared in an interview on Reuters television. NEI also issued a statement on the report. The NRC task force that wrote the report will brief the commissioners on its recommendations in a webcast meeting July 19. A commission press release on the report is here.

  • Tokyo Electric Power Co. has measured high levels of radioactivity inside reactor building 2 at the Fukushima Daiichi nuclear energy facility. The company believes the source of the radioactivity is steam from the reactor. TEPCO has been using robotic measuring devices to conduct radiation surveys inside three reactor buildings and in areas surrounding the buildings since early this month.
