Current Status of Decommissioning Activities at Chernobyl NPP

Dmytro Stelmakh (SSE Chernobyl NPP, Ukraine)

Chernobyl NPP is one of five nuclear power plants of Ukraine. It was finally shut down in 2000 in accordance with international commitments of Ukraine to the G7 countries.

A deferred dismantling strategy was accepted for ChNPP, where the most contaminated equipment of the reactor facility will be preserved and further dismantled after long-term safe enclosure.

At present, the preparation for safe enclosure stage is underway. Its objective is to bring three units of ChNPP to a condition ensuring their long-term safe enclosure under supervision, with minimum resource consumption.

The main activities at the stage are:

· Creation of conditions which will guarantee the reliable isolation of reactor facilities up to 2065.

· Creation and operation decommissioning infrastructure;

· Spent nuclear fuel and RAW management;

· Dismantling of auxiliary equipment;

· Decontamination and release materials from regulatory control

· Decommissioning of the cooling pond
