Operational and technical documentation agreed with the State Nuclear Regulatory Inspectorate of Ukraine, and based on the conclusions of the state nuclear and radiation safety review, establishes the design service life of the Shelter Object’s localizing structure until 31 October 2029, with the possibility of extension subject to an appropriate safety justification. This extension is intended to support the safe preparation and dismantling of unstable structures. As of the reporting date, the Shelter Object’s localizing structure continues to perform its functions in accordance with the technological regulations governing the NSC-Shelter complex.
Following the drone strike of 14 February 2025 and the subsequent fire-fighting activities, the arch of the New Safe Confinement (NSC) – designed to ensure confinement of radioactive materials in the event of failure of the Shelter Object’s localizing structure – has lost its ability to fully maintain the leak-tightness of its internal volume. Nevertheless, the NSC’s protective envelope continues to partially fulfill its primary function, namely the ecological isolation of the destroyed unit of the Chornobyl Nuclear Power Plant from the environment.




From March 15 to 21, 2026, a seminar on digitalization and paperless operations in the nuclear industry was held at Temelín Nuclear Power Plant (Chech Republic) with the support of the World Association of Nuclear Operators, Paris Centre (WANO).
