The unfortunate effects of the COVID-19 pandemic on nuclear new-build projects haven’t stopped with Vogtle: EDF Energy this morning reported that the expected startup date for Unit 1 at its Hinkley Point C site is being pushed from late 2025 to June 2026.
In addition, the project’s completion costs are now estimated to be in the range of £22 billion to £23 billion (about $30.2 billion to $31.5 billion), some £500 million (about $686 million) more than the 2019 estimate, EDF said, adding the caveat that these revisions assume an ability to begin a return to normal site conditions by the second quarter of 2021.

Proton exchange membrane electrolyzers (PEMEs) have potential interest for use for hydrogen isotope separation from water. In order for PEMEs to be fully utilized, more information is needed on the stability of Nafion when exposed to radiation. This work examines Nafion 117 under varying total dosage and dose rate and in water or air. Analytical tools, such as infrared spectroscopy, ion exchange capacity, dynamic mechanical analysis, and total inorganic carbon-total organic carbon (TIC-TOC) were used to characterize the exposed membranes. The water from saturated membranes was analyzed by fluoride and sulfate emissions and TIC-TOC, which provided important data on the stability of the membranes during radiation exposure.
