At 15.30 hrs. of 4.11.91, when unit was under shut down, Class-III bus P supply breaker from Station Auxiliary Transformer tripped on inverse time over current protection. Diesel Generator-1 on Bus-P side started and its breaker closed. But the fault was on Bus side of the supply breaker and hence the DG-1 breaker also tripped on feeding the fault. The breakers connecting bus-P to the other leg, Bus-Q closed. This resulted in tripping of Bus-Q supply breakers also along with the tie breaker. Bus-P was then isolated & bus-Q was normalised and all essential loads were normalised through Bus-Q. The event was caused by high resistance contact in the breaker finger contacts causing deterioration of insulations. The event can be classified unter B-IR of user's manual as level 1/2. The small flame in the breaker was quenched before any serious consequences could occur. Even though Bus-P became fully unavailable, the other leg, Bus-Q was normalised within a short duration. Moreover the unit was also under cold shut down. Hence there was no serious effect felt on unit operation. Hence the lower rating of level-1.

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. […]

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 […]
