11 days will mark 12 years because the Great East Japan Earthquake and the accident on the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Station. As the inhabitants decline turns into extra severe in coastal areas resembling Iwate, Miyagi, and Fukushima, restore the prosperity of the realm for the institution of the youthful era has grow to be a significant problem.
At the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station, which brought about the worst accident in historical past, investigations and preparations are underway to take away the melted “nuclear fuel debris”, whereas development work to launch the handled water that continues to build up has been accomplished. is approaching.
At the Fukushima Daiichi Nuclear Power Plant, energy was misplaced because of the big earthquake and tsunami, and nuclear gasoline melted down in three reactors, inflicting a “meltdown” and releasing a considerable amount of radioactive materials.
In the reactors and containment vessels of Units 1 to three, “nuclear fuel debris” stays, which is melted nuclear gasoline blended with buildings, and the water used for cooling and groundwater grow to be contaminated water. It continues to extend at a tempo of 100 tons per day.
As of March 2, the quantity of handled water containing radioactive substances resembling tritium that is still after treating this contaminated water has reached roughly 1.33 million tons. I anticipate the tank to be full.
The authorities plans to begin releasing it into the ocean from spring to summer season this yr after diluting it to 1/40 of the usual, and the development of the undersea tunnel used for launch is anticipated to be accomplished in June.
On the opposite hand, there are deep-rooted voices of opposition, primarily from fishermen and others, and the problem is whether or not the federal government and TEPCO can acquire the understanding of the events involved because the discharge into the ocean is imminent.
In addition, the beginning of the elimination of “nuclear fuel debris”, which is taken into account to be the largest issue in decommissioning, is deliberate for Unit 2 after October this yr.
The preliminary extraction is positioned as a trial, and the plan is to extract a number of grams utilizing a robotic arm.
However, the entire quantity of “nuclear fuel debris” from Units 1 to three is estimated to be as excessive as 880 tons, and it isn’t potential to foresee a selected route for eradicating it.
Akira Ono, CEO of TEPCO’s Fukushima Daiichi Decommissioning and Decommissioning Engineering Company, mentioned in an interview on the first of this month, “Fuel debris retrieval and treated water issues are unavoidable in advancing decommissioning. 2019 may be a turning point in determining whether decommissioning work can proceed safely and steadily in the future.”
