Safety-relevant damage in the safety injection systems of French nuclear power plants
Published 19. May 2022

As of today (20 January 2022), the operator EDF has taken five of its reactor units off the grid due to cracks in the weld seams in the safety injection systems. According to statements by the French expert organisation IRSN, it cannot be ruled out at present that these crack indications are a generic problem that could also affect other plants. The following article provides an overview of the current state of knowledge. It is based on information from the French supervisory authority ASN, the operator EDF, and our French partner IRSN, with whom we maintain a close technical exchange via the European network ETSON.

On the 11th anniversary of the Fukushima nuclear accident
Published 10. March 2022

Once again, 11 March marks the anniversary of the nuclear accident at the Fukushima-Daiichi nuclear power plant in Japan. Several thousand workers are still doing their jobs on the plant site every month - primarily to prepare the dismantling of the destroyed reactors. On the occasion of the anniversary, we look back on the main events and developments of the past year in this article.

Towards a radiant future? Safety background to France's latest decisions on its energy policy
Published 21. February 2022

On 10 February 2022, French President Emmanuel Macron explained to the public how he envisages France's energy supply for the next decades. In addition to large-scale new construction projects for offshore wind farms, the expansion of nuclear power in particular is intended to cover the electricity demand that will arise by 2050: Six new types of EPR2 reactors are to be built, and the construction of eight more is to be examined. In addition, the development of a so-called Small Modular Reactor and the long-term operation of older nuclear power plants are planned. What the new reactor types and long-term operation mean from a technical (safety) perspective is outlined below.

Nuclear energy worldwide 2022
Published 11. February 2022

What has happened in the field of nuclear energy last year? What developments can be observed internationally? In 2021, a total of six new reactor units were connected to the grid, including one small modular reactor – on the other hand, ten units have been decommissioned, including three of the six German units that have remained until then. Accordingly, the installed net capacity decreased to a total of 388,600 megawatts.

Brokdorf, Grohnde, Gundremmingen C – a brief review
Published 27. December 2021

On 31 December 2021, three of the remaining six German nuclear power reactor units will cease power operation: Brokdorf, Grohnde and Gundremmingen C. Brokdorf has been supplying electricity to the grid since December 1986, Grohnde and Gundremmingen C since the beginning of 1985 - together, these reactors have been in operation for over a hundred years. The final three units (Isar 2, Lingen and Neckarwestheim II) will be shut down on 31 December 2022.

Better safe than sorry – current research on IT attacks via supply chains
Published 21. December 2021

"The Internet is on fire" – that was the message in mid-December 2021 when a security loophole in the Java framework log4j became known, making a wide range of cyber-attacks possible. The Federal Office for Information Security then raised a "red" alert, the highest warning level. Quite a number of companies around the world have turned out to be affected. On behalf of the Federal Ministry for the Environment, GRS experts are analysing cyber-attacks and security incidents that may also be relevant for German nuclear facilities and installations in order to protect them accordingly.
