☢️ Zaporizhzhia Nuclear Power Plant's power unit 5 leaks from reactor's primary circuit.
As the Energoatom State Enterprise National Nuclear Energy Generating Company (NNEGC) explained, the primary circuit water with a boric acid solution began to enter the turbine hall deaerator, and from there to all steam generators, due to the incompetence of Russian personnel, in particular the shift supervisor of the chemical workshop, who lost control over the saturation of the special water purification filters.

The incident with the leakage of reagents occurred as a result of the actions of the Russian invaders in connection with the illegal transfer of power unit No. 5 of Zaporizhzhia NPP to the state of hot shutdown.

According to Petro Kotin, Energoatom’s president, the actions of the invaders can lead to the loss of the integrity of the steam generator tubes, which does not comply with the regulations for the safe operation of the power unit. "With their actions, the invaders once again jeopardise the safety of the plant's operation and cause the constant degradation of equipment and an increase in dangerous cases of its failures. And this can lead to an emergency at any moment," Kotin emphasised.

Moreover, similar actions are carried out with power unit No. 3. In particular, attempts are being made to remove power unit No. 3 from repair and warm it up to a hot shutdown state in order to bring power unit No. 5 to a cold shutdown state.

Energoatom recalled that a number of emergencies have already occurred due to Russians violating licensing conditions at Zaporizhzhia NPP, the most recent of which happened on 14 November 2023.

"In addition, the senseless decision of the current 'managers' of the plant to transfer it to a 'hot' state has led to a significant increase in liquid radioactive waste at the plant site, which poses potential harm to personnel, the public and the environment," the NNEGC explained.
