Step-by-step challenge of debris characterization for the decommissioning of Fukushima-Daiichi Nuclear Power Station (FDNPS)
TL;DR: In this article , the authors reviewed the step-by-step attempts on debris characterization after the severe accident of Fukushima-Daiichi Nuclear Power Station (FDNPS) and concluded that it was rather difficult to investigate the reactor inside in the first few years.

Perspectives on a Severe Accident Consequences—10 Years after the Fukushima Accident
TL;DR: In this paper, the authors discuss scientific issues that draw international attention from the public and experts during the last 10 years after the Fukushima accident, including severe accident analysis methodology, impact on the views of nuclear reactor safety, dispute on the safety of fishery products, discharge of radioactive water to the ocean, status of decommissioning, and needs for long-term monitoring of the environment.

Dimensionless parameters controlling the spreading behaviors of free-falling molten metal on dry surface
TL;DR: In this article, a correlation between the spreading and deposition behaviors and the dimensionless numbers of Re, We, Pe, Oh, and Bo was observed, where effects of inertial force on the spreading process were relatively low.

Current knowledge on core degradation phenomena, a review
TL;DR: In this article, it is shown that reflooding of an overheated core can result in a renewed temperature rise with localized melt formation, additional release of fission products, and in an increased hydrogen production; this increases the threat to the integrity of the reactor pressure vessel and to the containment as well as potentially misleading the operators regarding their recovery actions.
