All samples sintered up to 900 °C show a rhombohedral structure.
Introduction Nasicon structure is a 3D channel structure which enables good ionic conduction.
The LSP phase observed in the samples has a rhombohedral structure except for the sample sintered at 1000 °C which showed a monoclinic structure.

For in-core structures, some specific issues typical of the new concept of the SCWR require further investigation.
The main material groups of interest for in-core structures are ferritic/martensitic steels, austenitic stainless steels, Ni-based alloys and ODS alloys.
In general terms, the loops are composed of circuits and systems, which perform the same functions, but differ markedly in structure.
The detailed structure of all systems is out of the scope of this paper.
Water chemistry specifications for materials testing in supercritical water arise from the present practice in water chemistry control in conventional light water reactors, especially the boiling water reactors (BWR), where normal water chemistry (NWC) or hydrogen water chemistry (HWC) are most commonly applied.
