Unit 4 of NPP Bohunice was shut down for refuelling and yearly overhaul, the fuel and all internals were out of RPV. RPV filled by pure condensate. On June 15 film dosimeters (FD) of 3 workers of a contractor making preparation of manipulator for inspection of weldings in increased values of effective doses received by those workers which were 29.48, 9.13, and 5.18 mSv. Cumulated doses shown by operational electronic dosimeters (ED) however, were 0.259, 0.225, and 0.28 mSv. Investigations of discrepancies between two kind of dosimeters revealed that the workers put off ED during non-standardized work they had to perform out of scheduled workplan. The use of ED during the work was prescribed by the Work Order issued by the Rad. Protection Dept. of the NPP operator for this particular work. The cumulated effective dose for the year 2000 in case of worker, who received maximum was 32.11 mSv. In spite of the fact the NPP yearly limit, 20 mSv per year averaged over 5 years, was exceeded, the permitted effective dose in a single year, 50 mSv, however, was not exceeded. The effective dose received by the worker was classified as an "unplanned exposure" caused by violation of both, work and radiation protection procedures. The workers in question were temporarily forbidden to enter the controlled zone of the NPP and a written notification and information on the event was sent to the company management.
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, […]
