The operational and technical documentation, agreed with the State Nuclear Regulatory Inspectorate taking into account the conclusions of the state nuclear and radiation safety expertise , sets the operating life time of the containment structure of the Shelter object until October 31, 2029, with the possibility of its extension subject to safety justification for the purpose of safe preparation and dismantling of the unstable structures. As of the current time, the containment structure of the Shelter object performs its functions in accordance with the technological regulations of the NSC-Shelter complex.
Despite the fact that, as a result of the strike by a drone on 14 February 2025 and the aftermath of the fire-fighting operation, the arch of the New Safe Confinement (NSC)—which was constructed to ensure the containment of radioactive materials in the case if the containment structure of the ‘Shelter’ facility failed, lost its ability to fully seal its internal volume, its protective shell continues to partially fulfill its key role — the ecological isolation of the destroyed power unit from the surrounding 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).
