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).

Nuclear power is an important component in the fight against climate change, but independent regulation is needed to gain the public’s---and governments'---trust, according to a March 6 article in The Economist, “Nuclear power must be well regulated, not ditched.”
The article reviews the negative effect that the Fukushima Daiichi accident had on the worldwide nuclear industry following the earthquake and tsunami in March 2011. Japan’s direct economic cost, estimated at more than $200 billion, was larger than that of any other natural disaster the world has seen, according to the article.

China will have the world's largest nuclear power fleet within a decade, an International Energy Agency official noted during a session at the High-Level Workshop on Nuclear Power in Clean Energy Transitions, World Nuclear News reported on March 3.
The workshop was held jointly by the IEA and the International Atomic Energy Agency.
The IEA official, Brent Wanner, head of Power Sector Modelling & Analysis for the agency's World Energy Outlook publication, said that as nuclear fleets in the United States, Canada, and Japan reach their original design lifetimes, decisions will have to be made about what will happen after that. Absent license renewals, the contribution of nuclear power could decline substantially in those countries while China’s reactor building program will boost it into the first position.

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.

Vice News has published a video on YouTube that follows two farmers from the Fukushima Prefecture, Noboru Saito and Koji Furuyama. Saito, who grows many different crops on his farm, says that the rice grown in the area is consistently rated as the best. Furuyama specializes in peaches and explains his strategy to deal with the stigma of selling fruit from Fukushima: grow the best peaches in the world.

Britain and Japan have signed a research and technology deployment collaboration to help automate nuclear decommissioning and aspects of fusion energy production. According to the U.K. government, which announced the deal on January 20, the £12 million (about $16.5 million) U.K.–Japanese robotics project, called LongOps, will support the delivery of faster and safer decommissioning at the Fukushima Daiichi reactors in Japan and at Sellafield in the United Kingdom, using long-reach robotic arms.
The four-year collaboration on new robotics and automation techniques will also be applied to fusion energy research in the two countries.
Funded equally by U.K. Research and Innovation, the U.K.’s Nuclear Decommissioning Authority, and Japan’s Tokyo Electric Power Company, the LongOps project will be led by the U.K. Atomic Energy Authority’s (UKAEA) Remote Applications in Challenging Environments (RACE) facility.

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.

The seismic event was huge and was felt all over the world. With a moment magnitude of over 9.0, the earthquake and was the fourth largest ever in the more than 100 years of recorded history. Huge land masses shifted as much as 2.4 meters, and the rotation of the earth was changed so that days were suddenly just a little (but measurable) bit shorter. It had sped up the world.

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.)
