A magnitude 7.3 earthquake struck off the east coast of Honshu, Japan, at 11:36 p.m. (local time) yesterday, resulting in significant ground shaking near the epicenter, much structural damage, at least four deaths, and a power outage affecting more than 2 million households, including some 700,000 in Tokyo. (According to Japanese utility Tepco, power was restored to all households by 2:52 a.m. on Thursday.)

“A group of professionals having fun in the fields of decommissioning and environmental sciences for the nuclear industry.”
That’s how the ANS DESD describes itself on its website. The focus of this professional division is the development and use of skills and technologies needed for the optimal management of the end-of-life care (decommissioning, decontamination, and remediation), long-term surveillance, and maintenance of nuclear installations, materials, facilities, and sites.

News programmers’ hunger for stories about the aftermath of the earthquake and subsequent tsunami that caused three reactor meltdowns at Fukushima Daiichi in March 2011 shows no signs of abating.

The Japanese government will soon announce the decision to dispose of stockpiled Fukushima wastewater into the Pacific Ocean, according to an AP News story published last Friday. The decision is years in the making and follows the guidelines from a panel of government-appointed experts named the Subcommittee on Handling of the ALPS-Treated Water (ALPS Subcommittee).

Along with many other media outlets on March 11, the PBS NewsHour reported on the continuing recovery efforts from the earthquake and tsunami that devastated northeastern Japan 10 years ago. The segment, "Japan marks 10th anniversary of Fukushima nuclear disaster," is just over eight minutes long, most of which discusses the effects of the earthquake and tsunami on the region and Japan’s preparedness for the next major natural incident.

The mission of Tokyo Electric Power Company Holdings (TEPCO), and my personal mission, is to safely decommission the damaged Fukushima Daiichi nuclear power station and thereby contribute to the revitalization of Fukushima.
In performing this important work, we are guided by the principle of balancing the recovery of Fukushima with the decommissioning of the Fukushima Daiichi nuclear power station, doing everything possible to mitigate the risks as we progress. Since the accident on March 11, 2011, we have stabilized the site and alleviated many of its crisis aspects.
Most significantly, we have been making efforts to improve the working environment by reducing the contamination on the site due to the accident. About 4,000 workers are currently engaged at Fukushima Daiichi. The average monthly radiation dose for those workers has been reduced from 21.55 mSv (2,155 mrem) immediately following the accident to 0.3 mSv (30 mrem).

The accident at Japan's Fukushima Daiichi nuclear power plant on March 11, 2011, has sparked many safety improvements in the nuclear industry over the past decade. Lessons from the accident and its aftermath will influence firms and regulators as they consider the future design, construction, operation and decommissioning of nuclear reactors.
An American Nuclear Society webinar, “Nuclear News Presents: A Look Back at the Fukushima Daiichi Accident,” held yesterday was attended by more than 1,550 viewers and generated about 150 questions to the panelists. The attendance was the largest ever for an ANS webinar.
The panelists were Mike Corradini, emeritus professor, University of Wisconsin; Dale Klein, former chairman of the U.S. Nuclear Regulatory Commission; Joy Rempe, principal, Rempe and Assoc. LLC; Lake Barrett, senior advisor, Tokyo Electric Power Company and Japan’s International Research Institute for Nuclear Decommissioning (IRID); and Paul Dickman, senior policy fellow, Argonne National Laboratory.
The webinar’s recording and slides are available here, along with an e-version of the March issue of Nuclear News, which features a cover story on the Fukushima Daiichi accident.

It was a rather normal day back on March 11, 2011, at the Fukushima Daiichi nuclear plant before 2:45 p.m. That was the time when the Great Tohoku Earthquake struck, followed by a massive tsunami that caused three reactor meltdowns and forever changed the nuclear power industry in Japan and worldwide. Now, 10 years later, much has been learned and done to improve nuclear safety, and despite many challenges, significant progress is being made to decontaminate and defuel the extensively damaged Fukushima Daiichi reactor site. This is a summary of what happened, progress to date, current situation, and the outlook for the future there.

There has been no off-site impact from the February 13 earthquake that struck off the east coast of Japan near the Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO) reported on February 19. The earthquake, however, has caused a water leakage from two of the site's primary containment vessels (PCVs).
A nuclear alert order was issued by the plant about 20 minutes after the earthquake, and the water treatment and transfer facilities were shut down. Inspections after the event revealed no anomalies and the nuclear alert order was rescinded on February 14.
The nuclear plant in Fukushima Prefecture in northeastern Japan is now undergoing decommissioning.

Decommissioning work in parts of the Fukushima Daiichi plant in Japan has been delayed after engineers discovered that sandbags placed in the basements of buildings near Units 1 and 3 were found to contain excessive radiation levels. Tokyo Electric Power Company (TEPCO) operates the plant and is in charge of the decommissioning efforts following the accident caused by the earthquake and tsunami on March 11, 2011.

Welcome to 2019! I hope everyone who took a break enjoyed it. For those who didn't, why didn't you? Initially, I had thoughts of trying to separate from social media and news to a significant extent during the holidays but, after conversations with Linda Zec (our wonderful ANS staff liaison for the Social Media Team, among many other things) decided that it was impractical to do so for a variety of reasons. So, as the holiday furor ebbed and flowed and I continued, still connected, to read news and year-end summations, I found myself wishing that there wouldn't be so much frustrating news in 2019. That's why I decided to open my eighth calendar year writing for the ANS Nuclear Cafe with a wish list, or "listicle" in the inside jargon, if you prefer. Here, in ascending order of importance (or, I suppose, increasing order of unlikelihood) are my five wishes for this new year in nuclear energy. (All on one screen; no annoying "next" buttons. You're welcome.)

Earlier this month, Japanese Prime Minister Shinzo Abe conducted a visit to Tokyo Electric Power Company's Fukushima Daiichi nuclear station to examine conditions at the site and to gauge TEPCO's response to numerous ongoing problems. When Abe spoke to reporters after the visit, he mentioned (for reasons still unknown) that he had suggested to TEPCO that it decommission Unit 5 and Unit 6 on the site, so that it could focus its efforts squarely on the work required to recover from the nuclear accidents at Units 1, 2, and 3. This was reported with some surprise in many quarters.
