NPP Krsko was operated at full power. At 1:00 a.m. the asymmetry of phases of electrtical current on heater drains pump motor was noted. Measurement of currents on electrical generator, as a diagnostic tool, started. An ampere-meter was connected in the protection circuit of the differential relay. When adjusting measuring range of the ampere-meter, the circuit was interrupted which caused activation of the relay and subsequently disconnection of the switchyard breaker and of the BBC breaker followed by turbine and reactor trip (power was greatger than 10%). The investigation showed that the asymmetry was caused by open disconnect switch of one phase on 400 kV power line, which serves for external power supply of the power station. After the fault was corrected, the station was connected to the electric supply system. The event was rated level 0 under the criterion defence in depth with no safety significance (Section III.-2.2.2, Table II). It was establshied that a work order together with written instruction for current measurements on generator was issued, but no measurement procedure existed.
The Netherlands has agreed to allow Urenco to be used for the British military nuclear program. This clears the way for uranium enriched by Urenco to be used in nuclear weapons. With his decision, Foreign Minister Berendsen (CDA Christen Democrats) is departing from the principle that civilian and military nuclear applications must remain strictly separate. […]

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 […]
