Safety of fusion power plants from fundamental to current state of the art

Stieglitz, R.; Jin, X. Z.; Boccaccini, L. V.; Carloni, D.


Since the beginning, magnetic fusion adopted safety and environmental aspects as central elements
for the development of a future fusion power plant (FPP). First the lecture introduces fundamental phrases such as safety, reliability and security which relevant for a safety assessment and valid for all technological systems. Based on this methods and approaches are presented to quantify a “safe state” or vice versa to measure the risk. This in turn requires computation of the probability of a failure by an adequate system description for which the most relevant approaches are sketched. Here either deductive methods as the Fault Tree Analysis (FTA) or inductive, qualitative procedures as the Failure Mode Effect Analysis (FMEA) are most frequently used. Also the approach to apply a Master logic Diagram (MLD) is explained. Fusion reactors have to be licensed as any other nuclear installation according to individual nation frameworks and laws. In this context exemplary the German regulations are briefly explained, before in a next step the procedures for a safety demonstration are described. One central
element therein is the protection, which is described by the dose limits, and another one of monitoring denoted as dosimetry. ... mehr
