HITACHI, Ibaraki Prefecture–Another robot has been developed for the elusive goal of locating melted fuel and surveying the interior of the No. 1 reactor at the Fukushima No. 1 nuclear plant.

A team of engineers and researchers from Hitachi-GE Nuclear Energy Ltd. and the International Research Institute for Nuclear Decommissioning revealed the robot on Feb. 3.

Tokyo Electric Power Co., operator of the plant, plans to deploy the robot into the No. 1 reactor before the end of March.

The robot will be fitted with a censoring unit mounted with a camera, dosimeter and lighting. Its purpose is to give TEPCO an idea of the location and condition of the melted nuclear fuel…

Radiation limit for contaminated soil in reuse experiment lowered after local opposition

The radiation limit for soil contaminated by the Fukushima nuclear disaster in an experiment to reuse it in construction was lowered from 8,000 becquerels per kilogram to 3,000 becquerels per kilogram after strong opposition from a local mayor, it has been learned.

The experiment is to be carried out at a temporary storage site in Minamisoma, Fukushima Prefecture, where around 1,000 bags of contaminated soil will be opened, made into construction foundations, and their radiation levels measured. The experiment will be done to check, among other things, whether the radiation exposure dose remains at the yearly limit of 1 millisievert or less. The experiment will cost around 500 million yen. The results are expected to be put together next fiscal year or later.

Radiation levels in units 1 and 3 remain much higher than in unit 2, TEPCO unable to investigate conditions in there

dunrenard's avatarFukushima 311 Watchdogs

As I wrote in my previous blog article, we cannot talk or know if there is an actual increase at this time, because it is the first measure they took at that place at this deep. To know if radiation is increasing we would need Tepco to make a 2nd measure at that place and that deep, and then to compare both measures. https://dunrenard.wordpress.com/2017/02/05/recently-found-fukushima-daiichis-reactor-2-high-level-of-radiation-does-not-mean-radiation-increase/

In Mali Martha Lightfoot’s own words: ” The measuring capacity is just getting better and they are reaching parts of the containment they were unable to monitor before. I think it’s important not to confuse more accurate readings with the misconception that they indicate that the levels are rising. It is shocking enough to get an indication of how high the levels still are. And we may find, as technology improves, that parts of the containment are higher still. But, that still does not indicate that…

NRA’s radioactive soil concerns omitted from minutes of closed-door meeting

NRA’s radioactive soil concerns omitted from minutes of closed-door meeting
Concerns raised by the Nuclear Regulation Authority (NRA) on how radioactive soil from the Fukushima nuclear disaster would be reused were omitted from the minutes of closed-door meetings on the issue, the Mainichi Shimbun has learned.
It has already come to light that comments from the Ministry of the Environment that could be interpreted as attempting to manipulate the conclusions of the meetings were left out when the minutes were publicly released. The latest revelation means yet another important part of the minutes is missing.
The meetings were held by the Ministry of the Environment between January and May last year with various radiation experts in attendance. In June, the experts decided to manage and reuse contaminated soil with levels of radioactivity under 8,000 becquerels of cesium per kilogram in public construction projects.
Related legislation reads “When deciding on technical…
