On March 9, the United Nations Scientific Committee on Atomic Radiation (UNSCEAR) published an advance copy of its latest (third) report on the health effects from the Fukushima Daichi nuclear accident which commenced on March 11, 2011. UNSCEAR 2020 Report – Annex B – Advance Copy The report shows signs of having been rushed out … [Continue Reading]

In early 2019, four French EDF scientists wrote a 22 page report on load following in French nuclear reactors. The English version was first published on April 1 2020 but this has only recently been brought to my attention (ie mid Jan 2021). This report is instructive and worrying, and requires careful reading. In essence, … [Continue Reading]

Recent newspaper reports have expressed concern about the apparent decision by the Japanese Government and TEPCO to discharge large volumes of radioactive tritiated water from the stricken Fukukshima nuclear power station in Japan into the Pacific Ocean. I have expressed concern myself about this proposed decision -see here. Instead I recommend that TEPCO and the … [Continue Reading]

This letter was sent to the editors of the Scotsman and the Herald on September 25, 2020. Sirs Very recently, the Office for Nuclear Regulation (ONR) gave permissions to EDF to re-start for six months two ancient, unsafe reactors at the Hunterston B nuclear power station on the Clyde coast. These reactors are among the … [Continue Reading]

In recent years, the share of the UK’s electricity supplied by renewable energy (RE) sources has increased substantially to the point that RE is now the second largest source after gas: It now supplies 20% to 25% of our electrical needs. This is greater than the amount supplied by nuclear – about 15% to 18%. … [Continue Reading]

The SARS-Cov-2 pandemic and concomitant economic recessions have resulted in many calls for Green New Deals (GNDs) to create jobs and tackle climate change. For example, in November 2019, the European Commission published a series of documents aiming for a Green New Deal see https://ec.europa.eu/info/strategy/priorities-2019-2024/european-green-deal_en  And in April, the climate and environment Ministers in 17 … [Continue Reading]

At present (May 2020), the two EdF reactors at the Hunterston Nuclear Station (R3 and R4) on the shore of the Firth of Clyde in Scotland have been shut for about 2 years for safety reasons – pending review by the Office for Nuclear Regulation (ONR). Both reactors are 44 years old, ie well past … [Continue Reading]

Recently the US science journal, Bulletin of Atomic Scientists, published an article with the headline “Britain has 139 tons of plutonium. That’s a real problem.” https://thebulletin.org/2020/04/britain-has-139-tons-of-plutonium-thats-a-real-problem/. It was well written by three German/Austrian academics Christopher Fichtlscherer, Friederike Frieß, and Moritz Kütt who clearly know their stuff. Below is a photo of the NDA’s plutonium store … [Continue Reading]

Summary Nuclear facilities emit very large amounts of tritium, 3H, the radioactive isotope of hydrogen.  Much evidence from cell/animal studies and radiation biology theory indicates that tritium is more hazardous than gamma rays and most X-rays. However the International Commission on Radiological Protection (ICRP) continues to underestimate tritium’s hazard by recommending  a radiation weighting factor … [Continue Reading]

EXECUTIVE SUMMARY At present (October 2019), the proposed 3.2 GW nuclear plant at Hinkley Point C (HPC) in Somerset is in its early construction stages. EDF is pressing ahead, apparently in the hope of persuading politicians not to abandon a partly completed project. However the HPC project is highly controversial and its completion remains in … [Continue Reading]
