The cover design depicts white hexagons that are similar to a tortoise-shell pattern. This represents the ancient Japanese symbol of the desire for long life. Coincidentally, this is also the shape of the core fuel assemblies in the high-temperature engineering test reactor, “HTTR”.
The top left figure shows a three-dimensional (3D) map visualizing the air dose rate and highly contaminated region near Unit 1/2 exhaust stack at TEPCO’s Fukushima Daiichi NPS (1F). The bottom right figure shows HTTR-Hydrogen Production Test Facility.
The 3D map visualizes the radioactive contamination situation within the 1F site and is realized by the integrated Radiation Imaging System (iRIS), which comprises a combination of technologies from different fields, including radiation measurement. This system contributes to the reduction of radiation exposure of workers and work planning. Further details can be found on page 23 in Chapter 1, Topic 1-10.
The hydrogen production project utilizing HTTR heat was launched in FY2022 to establish the technology connecting a reactor with a hydrogen production facility. Further details can be found on page 62 in Chapter 6, Highlight.
