TL;DR: In this paper, a test facility has been constructed at Technical Research Centre of Finland (VTT) to simulate as accurately as possible the ex-vessel core particle bed in the conditions of Olkiluoto nuclear power plant.

TL;DR: In this paper, the applicability and effectiveness of a range of model equations to represent the accumulation of creep strain in various engineering alloys was reviewed during the course of the EU-funded Advanced-Creep Thematic Network, ECCC-WG1.

TL;DR: In this paper, the authors used inspection data to establish guidelines for inspection data for low-alloy steels and applied them to ductile steels with relatively slow development of creep cavitation in conventional creep testing.

TL;DR: In a hypothetical severe accident in a nuclear power plant, molten materials may come into contact with concrete, causing concrete ablation in five HECLA experiments the interaction between metallic melt and concrete was investigated by pouring molten stainless steel at almost 1800°C into cylindrical concrete crucibles The tests were transient, ie no decay heat simulation was used as mentioned in this paper.

TL;DR: In this article, a range of SPC assessment methodologies, benchmarked for the ECISS/TC 101 WG1 standard, are compared for verifying the best practice used in the standard.
