As a result of the armed aggression of the russian federation, the occupation of the territory of the Exclusion Zone by russian military units in the period from 24 February to 31 March 2022, a situation in the Exclusion Zone has emerged making it impossible to continue routine operation of enterprises in this territory.

In this regard, the SNRIU, based on the analysis of information received from enterprises engaged in the nuclear energy use in the Exclusion Zone, within its authorities of the state regulatory body for nuclear and radiation safety, in the framework of implementation of the authorizing and licensing procedures envisaged by the legislation, in accordance with the Law of Ukraine "On Authorizing Activity in the Field of Nuclear Energy Use", has reviewed the issue of licensees’ capabilities to comply with the conditions of the licensed activities in accordance with the rules and standards on nuclear and radiation safety and licensing conditions.

As a result of consideration of this issue, due to the inability of licensees to comply with the terms and conditions of carrying out activities established by the rules and standards on nuclear and radiation safety, a decision was made to terminate validity of a number of issued licenses in the field of nuclear energy use, namely:

• on decommissioning of Chornobyl NPP units 1, 2 and 3;
• in the field of Radwaste management (ChNPP, Central Radioactive Waste Management Enterprise (CRME));
• radiation sources use (Central Radioactive Waste Management Enterprise (CRME), ChNPP, Ecocenter, Institute for Safety Problems of NPPs of the National Academy of Science of Ukraine).

At the same time, it was pointed out that the loss of capacities was not the fault of the licensees, but due to force majeure circumstances related to the occupation and seizure of the Exclusion Zone by the military units of the russian federation.

The SNRIU, in accordance with the Law of Ukraine “On Authorizing Activity in the Field of Nuclear Energy Use”, continues analyzing the capability of other economic activity of entities operating in the field of nuclear energy use to comply with the conditions of respective activities.
