Original Abstract

This report summarises the technical and organisation findings of the independent investigation team, appointed mid-October 2022 to investigate the root cause of the failures of the two turbo-circulators, to be installed in the ESS Target primary cooling loop. The equipment failed the preliminary Factory Acceptance Test (pre- FAT). The root-cause-analysis of those failures are presented and the most probable causes are identified to support a successful ESS operation.
