![]() “The nuclear phase-out by April 15, that’s this Saturday, is a done deal,” Christiane Hoffmann, a spokesperson for German Chancellor Olaf Scholz, said this week.Ĭritics say turning off the last three plants amid high energy prices, potential shortages, and a continent working to wean itself off Russian energy imports is irresponsible, without even taking into account nuclear power’s role in helping Germany meet ambitious climate targets. ![]() Now, Germany’s government is pushing ahead with the nuclear phaseout, despite calls from opposition parties-and members of one party within the current coalition, the pro-business Free Democrats-to keep the plants online longer. ![]() Facing potential energy shortages as a result of Russia’s war in Ukraine, German leaders said it was a “necessary” step to ensure the country had enough energy to make it through the winter. Originally slated to shut down at the end of 2022, German officials made the decision last fall to keep the country’s three remaining nuclear plants-Isar 2 in Bavaria, Neckarwestheim north of Stuttgart, and Emsland in Lower Saxony-online for a few extra months. Installation instructions for the modern NJOY components can be found on their respective repository on GitHub.BERLIN-When Germany powers down the last of its nuclear power plants on Saturday, it will mark a historic shift decades in the making-and comes in the midst of fierce debates about how Germany and Europe will ensure their energy security for tough winters ahead and meet their ambitious climate goals. Instructions for obtaining, compiling, and testing NJOY can be found here. Both NJOY versions and any modern NJOY components are free to use, but the copyright and license must remain with the code. NJOY2016, NJOY21 and our modern NJOY components are freely available under the BSD 3-clause license. Future components will include resonance reconstruction and data interpretation and manipulation tools. Prototypes can even be developed in Python before considering their implementation in C++.Įxamples of these components that are now available to users are our ENDFtk and ACEtk format components. Once all necessary components are developed in this way, creating a modern equivalent of any legacy NJOY module will be relatively trivial to achieve (from a pure coding point of view, excluding the required V&V efforts). Providing both a C++ and Python interface at the same time will also help in deploying these tools more quickly. As such, by focusing on deploying these components sooner rather than later, we can more quickly respond to user demands.īy moving away from the module structure of legacy NJOY to a component-based toolkit for a modern NJOY, we can allow for faster deployment of tools and integration in other tools. As indicated above, some or all of these components can be useful to end users as well as the final monolithic modules. An example here would be to obtain the elements of the R-matrix or T-matrix during resonance reconstruction.ĭeveloping or redeveloping a module requires first developing the underlying components that do the work (which may include a component to handle file formats) before these components can be integrated into the final module. In addition, some of the intermediate results produced during processing are not available to a user. However, for some fringe applications and a lot of day-to-day work where nuclear data users have specific questions (e.g., what is the cross section value at this energy), the monolithic structure of NJOY does not allow a user to get to that answer quickly or efficiently. The monolithic structure of NJOY is most useful when processing full evaluations into application libraries. As a result, NJOY21 will continue to use NJOY2016 for the foreseeable future. While it was initially intended to modernise NJOY on a module-by-module basis within NJOY21, the modernisation of NJOY has now gone in the direction of a component-based modernisation.
