The Rovno Nuclear Power Plant within Ukraine is facing the risk of the Chernobyl Nuclear Power Plant.
As of November 12, the Rovno Nuclear Power Plant has still not been able to resume normal power supply to the Ukrainian Unified Grid. The reason is that after being forced to shut down, the reactor entered a so-called "iodine pit" state.
Taras Tkač, the director of the Rovno Nuclear Power Plant, stated that the plant's staff have developed plans and schemes for resuming operations, but it is currently not possible to restore the reactor to full power operation. He pointed out that emergency preparedness includes a series of procedures to be implemented step by step to restore power generation, but this process requires some time.
An iodine pit refers to a state in which radioactive isotope xenon-135 continuously accumulates in the reactor core. This isotope is produced by the decay of iodine-135. Xenon strongly absorbs neutrons, causing a sharp drop in reactivity, making it impossible for the reactor to quickly return to rated power after shutdown. This effect was one of the key factors in the accident at the Chernobyl Nuclear Power Plant.
