Nuclear energy worldwide 2021
Published 10. May 2021

A good ten years after the nuclear accident in Fukushima, the nuclear phase-out in Germany is about to be completed: Three plants will be finally taken off the grid this year, the last three by the end of next year. But nuclear power plants (NPPs) are by no means shut down everywhere – around the world, very different paths are followed with regard to the use of nuclear energy for electricity generation.

Chernobyl: 35th anniversary of the nuclear disaster
Published 22. April 2021

26 April marks the 35th anniversary of the Chernobyl nuclear disaster: During an experiment, the power of the reactor in Unit 4 increased excessively due to a series of operating errors, and the fuel and coolant overheated.

Predicting infection routes: GRS team calculates the spread of SARS-CoV-2 aerosols in indoor environments
Published 01. April 2021

In the current Covid 19 pandemic, airborne aerosols that contain viruses are considered to be an important transmission route, especially in insufficiently ventilated rooms. To be able to make a sound assessment of the related risk of infection and to derive appropriate recommendations for action, the aerosol behaviour as well as representative ambient conditions must be considered in detail and realistically. Within the framework of the AeroCoV research project, scientists of GRS have applied the COCOSYS simulation code – which was developed and validated for the analysis of accidents and severe accidents in containments of nuclear power plants – for the first time for calculating the dispersion of SARS-CoV-2 aerosols. The related research report has now been published (download on the right side).

Hot Topic: GRS Research on Fire Protection in Nuclear Power Plants
Published 15. March 2021

Sound knowledge about the origin, spread and prevention of fires is essential to be able to assess and improve the fire safety of, among others, nuclear power plants (NPPs). Therefore, GRS continuously participates in research projects on the topic of fire protection in nuclear facilities which are conducted under the auspices of the OECD Nuclear Energy Agency (NEA).

Ten Years of Fukushima
Published 09. March 2021

On 11 March 2011, the most severe earthquake since records began in Japan occurred off the east coast of the Japanese main island of Honshū. The quake and especially the resulting tsunami devastated large areas of eastern Japan and caused an enormous number of casualties: Ten years after the tragedy, various official statistics count around 20,000 fatalities, and in December 2020, there were more than 2,500 people still considered missing. It is estimated that around one million buildings were destroyed or damaged.

10 Years of Fukushima Part 4: The Water
Published 26. February 2021

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.

Safety research for nuclear facilities is one of the main areas of GRS's work.

Searching for clues - Interview with the GRS radiation protection supervisor on the radiological consequences of Fukushima
Published 12. February 2021

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.
