Radiocarbon Measurements Reveal Underestimated Fossil CH4 and CO2 Emissions in London
Geophysical Research Letters, Volume 50, Issue 15, 16 August 2023., 2023 Abstract Radiocarbon (14C) is a powerful tracer of fossil emissions because fossil fuels are entirely depleted in 14C, but observations of 14CO2 and especially 14CH4 in urban regions are sparse. We present the first observations of 14C in both methane (CH4) and carbon dioxide (CO2) in an urban area (London) using a recently developed sampling system ...

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 The external reactor vessel cooling provides a means to stabilize the molten core inside the reactor vessel during the severe accident in nuclear power plants. For a credible evaluation of the chances of success of in‐vessel melt retention, one requires high‐fidelity predictions on the natural circulation flow around the reactor vessel and, in ...
