IR-40 (officially the Khondab Heavy Water Research Reactor), part of the Arak Nuclear Complex, was an Iranian 40 megawatt (thermal) heavy water reactor near Arak, adjacent to the 1990s era Arak Heavy Water Production Plant. The plant was made unusable in 2015 by removing the core and filling it with concrete, and it was hit by Israel in 2025 to keep it…
The analysis highlights History, Measurement, Art and Products as prominent areas in the source structure around IR-40.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
