Figure 3.
The heatmap shows time in days from 0 to about 1100 and temperature from 10 to 90 degree celsius. Sections labelled point sensors, first longitudinal optic fiber, second longitudinal optic fiber, and circular optic fiber are shown. A vertical region labelled missing data appears before the circular optic fiber section. Temperature increases from lower to higher values within each section with smooth gradients.Reconstructed data from the thermal loading of the HLW demonstrator cell
