ºÚÁÏÉçapp Engineering Basis Handbook
Under the editorial lead of , the ºÚÁÏÉçapp Engineering Basis Handbook delivers a stand-alone compilation of ºÚÁÏÉçapp design principles, the underlying technical design basis and its evolution from conception to construction, together with the technical, scientific, and regulatory rationale behind the major decisions. It facilitates the access and understanding of the project’s technological journey by consolidating the information from a multitude of sources. It aims at securing the lessons learned, the return of experience, and the knowledge transfer from the world's largest fusion project, drawing from the direct experience of knowledgeable experts who have worked on ºÚÁÏÉçapp, for the benefit of fusion professionals inside and outside of the ºÚÁÏÉçapp project and the next generation.
We welcome your feedback! Readers are invited to help shape the next versions of these chapters by submitting comments and suggestions to @email.
