External power to the six-reactor Zaporizhia nuclear power plant (NPP) in the Russian-occupied city of Enerhodar, Zaporizhia region, was disconnected more than three days ago, which raised concerns about the safety of the plant, according to an article in the British newspaper The Guardian, published on Saturday. Stress tests conducted by European regulators after the 2011 Fukushima disaster in Japan showed that a nuclear power plant must be able to operate without external power for 72 hours. According to the publication, there are signs that Russia is building a new power line from occupied Maripol to Zaporizhia NPP to resolve the crisis. "Zaporizhia NPP has been in a blackout for the second day, which is a significant violation of normal operating conditions. The largest nuclear power plant in Europe runs on diesel generators.
