In less than a year, and with the support of our partners, we are proud to have successfully delivered three APS: that of Stellarium, our reactor, which was then developed into two APS (Alvin, our fission experiment, and MegAlvin, our prototype), all structured and compliant with the highest standards of our industry<\/strong>. <strong>As good news never comes alone, the Nuclear Safety and Radiation Protection Authority has just placed us in the preliminary phase, with the goal of finalizing the DAC* for the creation of a basic nuclear installation for our fission experiment.<\/strong><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>It took us only a few months to deliver the APS for Stellarium, allowing us to apply all the parameters to the design of Alvin and MegAlvin. Thanks to the hard work of our team, we are simultaneously saving valuable time in the development of the demonstrators.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Validation of Safety Criteria<\/h2>\n\n\n\n<p>Our work has allowed us to validate two crucial aspects:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The intrinsic safety of the reactor in a way that is representative of Stellarium, as well as the validation of calculation codes with Alvin.<\/li>\n\n\n\n<li>The verification of obtaining a neutron flux similar to that of the first reactor with MegAlvin.<\/li>\n<\/ul>\n\n\n\n<p>Safety authorities consider these steps essential for the development of this new type of reactor.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Better Control of Technical Parameters<\/h2>\n\n\n\n<p>This milestone has enabled us to further mature our concept while identifying critical points and anticipating them by considering various solutions.&nbsp;<\/p>\n\n\n\n<p>At this stage, uncertainties regarding project size in terms of concrete mass, costs, complexity, and overall architecture have been reduced. As a result, we have delivered several technical elements, including:<\/p>\n\n\n\n<p><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Our plans and model 3D,<\/li>\n\n\n\n<li>The list of

of our strategy for managing salt and <a href=\"https:\/\/www.stellaria.fr\/en\/durabilite\/\">fuel corrosion<\/a>.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>We have also provided a <strong>Preliminary
