Fukushima nuclear disaster measured


This video from Japan says about itself:

Relationship between Yakuza gangs and TEPCO has become the closer for the accident

Oct 22, 2011

Syunsuke Yamaoka, representative of Access Journal, entered the site of Fukushima Daiichi Nuclear Power Plant illegally with a helping hand of the workers there and found Yakuza gangs arranged jobs there, especially jobs inside the buildings which would make the workers’ life get at stake and that the relationship between Yakuza gangs and TEPCO had got closer than that before the accident.

And he wrote a book ‘Fukushima Daiichi Genpatu Sennyuki (Book of Infiltration into Fukushima Daiichi Nuke Plant)’ about that with interviews with three workers working there.

Southampton researchers develop new tool to provide radiation monitoring in Japan

14 May 2013 Southampton, University of

A team of researchers from the University of Southampton have designed a new tool to intelligently combine nuclear radioactivity data in Japan. The technology harnesses the power of crowdsourced radiation data; an innovative resource which became available after the 2011 Fukushima nuclear disaster.

During March 2011, the second-largest nuclear emergency since Chernobyl 1986 was caused by a magnitude nine Tsunami hitting the North-East coast of Japan and severely damaging the nuclear power plant of Fukushima-Daiichi. The consequent nuclear accident provoked radioactivity increases of up to 1,000 times the normal levels in the area of Fukushima with more than 488,000 people being evacuated from their homes for the risk of nuclear contamination.

In response, private individuals brought forward the unprecedented effort of deploying 577 Geiger counters across the country to help the public monitor the spread of the nuclear cloud. These sensors were mostly built using low-cost open hardware boards such as Arduino and were able to stream radiation data in real time connected through the Cosm web platform. This crowdsourced sensor network, also known as the Cosm network, came to life in less than two weeks after the Tsunami and provided very relevant data to both official authorities and local citizens for monitoring the evolution of the disaster. More recently, the network was extended to 1,024 sensors contributed by several other organisations such as Safecast and the Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT). All together, the Cosm sensors provided more than 27 million readings since the day of the Fukushima disaster.

According to the researchers, a key element in order to incentivise people to take part in crowdsourcing projects is to help them understand these large quantities of data. To help people gain such an understanding, it is important to close the loop and feedback the results to the data contributors.

For this reason, the researchers have developed the Japan Nuclear Crowd Map (JNCM http://jncm.ecs.soton.ac.uk/): a web platform that combines into a single database the sensor readings provided from the three main crowdsourced radiation monitoring services: Cosm, Safecast, MEXT.

Matteo Venanzi, from the University of Southampton, who developed JNCM says: “The platform automatically collects raw radiation data from the online sensors and uses a non-parametric Gaussian process model to fuse the data into a single radiation map over Japan. The estimates are then shown to the users as a heat map and an intensity map, showing the average radioactivity in each prefecture. The users can also search by postcode to find out the radioactivity in their neighbourhood based on the latest predictions.”

JNCM is also available for smartphones with the JNCM Android app. Through the app, the users can visualise the radiation heat map directly on their phones as data are collected and also know the radiation level at their current location.

Yuki Ikumo, also from the University of Southampton, who developed the JNCM Android app says: “JNCM aims to be one of the future technologies for disaster managements in which the large participation of people will play a crucial role in community-based sensing crowdsourcing environmental monitoring tasks.”

JNCM users can now perceive the usefulness of this technology by freely accessing a number of radiation monitoring services based on the data contributed by thousands of crowd members.

JNCM is developed within the ORCHID project based in Electronics and Computer Science at the University of Southampton, which investigates how human and software agents can work effectively together to collect the best possible information from a disaster environment.

  1. Regulator to suspend Monju N-reactor’s restart work

    Jiji Press — May 15

    The Nuclear Regulation Authority decided Wednesday to order the operator of the Monju fast-breeder nuclear reactor to suspend preparations for resuming operations at the facility in Fukui Prefecture, central Japan.

    The NRA concluded that Monju operator Japan Atomic Energy Agency lacks the systems necessary to secure the safety of the facility.

    • Nuclear watchdog halts reactor tests

      Wednesday 15 May 2013

      by Our Foreign Desk

      Japan’s nuclear watchdog said today that the nation’s next-generation test reactor will not be allowed to restart due to safety violations.

      The Nuclear Regulation Authority’s decision is the latest blow to the Monju reactor and Japan’s nuclear fuel cycle programme, which is supported by the government but viewed with deep suspicion by most of Japan’s population.

      Monju uses plutonium fuel instead of conventional uranium and produces radioactive substances which are designed to be reused as fuel.

      After nearly 50 years in the works, the problem-plagued reactor, located in the city of Tsuruga in western Japan, is still struggling to get online.

      The watchdog’s five commissioners unanimously agreed that the reactor’s operator, the Japan Atomic Energy Agency, “is not ready to sufficiently secure the safety of Monju.”

      They said that the operator had repeatedly failed to conduct mandatory inspections on equipment and come up with improvement plans.

      Many experts have said Monju is a basket case and that Japan should abandon plans to achieve a full nuclear fuel cycle.

      The operator needs at least until January to catch up with the delays in safety checks but it is unknown when the suspension order can be lifted.

      Watchdog chairman Shunichi Tanaka said Monju operators “repeated the same mistakes even though they said they were analysing the root cause of the problem.

      “I think they lack fundamental understanding about safety.”
