Our five-part series "10 Years of Fukushima" looks at the nuclear accident in Japan from different perspectives. This week we present the lessons learned and consequences that the accident has had for nuclear power plant operation and supervision, both nationally and internationally.
The second part of our series "10 Years of Fukushima" deals with the radiological consequences of the events: How badly were the plant site and the surrounding area contaminated? How many people were affected and to what extent? What are the long-term effects of radioactivity on the region and what is the situation like today?
Physicist Dr Thorsten Stahl heads the Radiation and Environmental Protection Department of GRS, is the company's radiation protection supervisor and was part of the team with which GRS provided technical support to the Federal Government during the accident at Fukushima. In this interview, he explains what makes determining the long-term health effects of the accident so complex and how he assesses a possible discharge of contaminated water from a radiological point of view.
In our five-part series on the occasion of the 10th anniversary of Fukushima, today we look at the dismantling activities. The dismantling of a nuclear power plant (NPP) is a lengthy process.
Safety research for nuclear facilities is one of the main areas of GRS's work.
For about 10 years, our GRS colleague Dr. Michael Maqua has been performing the duties of the Ines officer for Germany on behalf of the Federal Environment Ministry. INES stands for "International Nuclear and Radiological Event Scale", a scale for the classification of nuclear incidents and accidents. More than 70 countries are currently using INES. The graduate engineer is engaged in international project management and answers all our questions about his work as an INES officer.
In addition to recovering the highly radioactive core melt from the affected reactor units, the disposal of enormous quantities of contaminated water represents the greatest challenge in the clean-up of the Fukushima Daiichi site. More than one million tonnes of it are stored in large tank areas on the plant site. While the space for new tanks will soon be exhausted at the site, the amount of water is increasing with each passing day.
In 2011, the most severe nuclear accident since Chernobyl occurred at the Fukushima Daiichi nuclear power plant site in Japan. The accident was classified at the highest level of the International Nuclear Event Scale (INES).

Our GRS colleague Dr Michael Maqua has been performing the function of INES Officer for Germany on behalf of the Federal Ministry for the Environment for more than 13 years. INES stands for "International Nuclear and radiological Event Scale", a scale for the classification of nuclear events and accidents. The trained engineer followed the events around the nuclear accident at Fukushima from the GRS emergency centre. In this interview, he answers our questions about how he remembers this time.
