- In this paper, the multi-point dynamics code BELLA and its benchmarking with respect to SAS4A/SASSYS- 1 is described for a small fast reactor cooled with natural convection of lead (ELECTRA). It is shown that BELLA is capable of reproducing the magnitude of mass-flow, reactivity, power and temperature excursions during design extension conditions with an accuracy better than 10%. Hence, the BELLA code can be used for safety-informed design and stability analyses of fast reactor systems, permitting to isolate essential phenomena and trends of significance for their safety assessment.

- In this paper, an optimized control drum system for the European Lead Cooled Training Reactor (ELECTRA) is proposed. By changing the number of rotating drums from 6 to 12, we succeed in reducing the maximum rotational worth of a single drum from 4 $ to 1.64 $. As a consequence, the safety margin during reactivity insertions is significantly improved.
