The Lead Radiographer and three assistant radiographers were completing two exposures lasting 35 seconds each. The set-up time for the exposures was approximately 15 to 18 minutes. After completing two exposures, one individual noticed that his pocket dosimeter read off scale, a second individual read their dosimetry at 0.5 mSv (50 mrem), the third individual read their pocket dosimeter as off scale, and the fourth individual was not wearing a dosimeter. Two individuals were wearing functioning rate meters and two were not. Additionally, the radiography crew was using a survey meter that was determined after the event to have had an electrical short and therefore was not functioning properly. Dosimetry for the three individuals that were wearing dosimetry was sent for emergency processing. The dosimetry readings were determined to be: 1) 112 mSv (11.2 rem), 2) 50 mSv (5.0 rem), and 3) minimal. The minimal reading was determined to be invalid since it was discovered that this individual left their dosimetry in their hard hat which they did not have with them at the time of the two exposures. For the fourth individual, who was not wearing any dosimetry, the licensee has estimated a preliminary dose of up to 450 mSv (45 rem). The licensee is in the process of confirming the dose to the third individual and the estimated dose to the fourth individual. NRC EN50904.
Everywhere you look, the nuclear industry’s hype machine is in overdrive. Goldman Sachs, Microsoft, and the UK government all tout small modular reactors as the silver bullet for climate change and energy security. Tech billionaires are hiring nuclear veterans. Wall Street is whispering about “round-the-clock power” for artificial intelligence data centers. For those old enough […]
Kernenergie en veiligheid: A wargame sought to test if a major radiological release that would prompt the evacuation of millions of civilians in South Korea could distract key US allies from assisting and rebuffing an all-out military invasion of Taiwan. The short answer was yes. The game originally presumed that China, wanting to keep the […]
Big batteries and EVs to the rescue again as faults with new nuclear plant cause chaos on Nordic grids The Finnish nuclear power plant Olkiluoto was finally connected to the grid last year, at an estimated cost of €11 billion compared to the original budget of €3 billion. That cost blowout forced its developer, the […]
A vast subsea nuclear graveyard planned to hold Britain’s burgeoning piles of radioactive waste is set to become the biggest, longest-lasting and most expensive infrastructure project ever undertaken in the UK. The project [UK's nuclear waste dump] is now predicted to take more than 150yrs to complete with lifetime costs of £66bn in today’s money...The […]
Last year, the Dutch Province of Limburg started an alliance in which, besides the local government, research institutes, small nuclear reactor (SMR) developers, utilities, industrial customers and funders cooperated. With this "Limburg SMR alliance" Limburg tried to lead the way towards an SMR in Limburg. The preferred site for a first SMR would be Chemelot, […]
