Important Stage for Chernobyl NPP: ChNPP Units Are Completely Free of Spent Nuclear Fuel

shelter-stabilizationJune 6 last Spent Fuel Assembly (SFA) was unloaded from the cooling pool of the Central Hall 1 and transferred to the wet type Spent Nuclear Fuel Storage Facility (ISF-1).

It should be noted that before completion of the extended operational time, on April 14, 2016 the State Nuclear Regulation Inspectorate of Ukraine (SNRIU) has issued the separate permit to SSE “Chernobyl NPP” to unload the damaged Spent Nuclear Fuel from Units 1,2 and to transport it to the “wet” type Spent Nuclear Fuel Storage Facility (ISF-1) for safe disposal and storage.

April 23, 2016 damaged Nuclear Fuel was completely removed from Unit 2.

After SNF retrieval from ChNPP Units Chernobyl NPP goes to a qualitatively new level of activity – it completed the stage of preparations for decommissioning and enters directly into decommissioning stage.

As a result of SNF unloading status of Units 1, 2 will be changed – these Units will not be considered as nuclear installations – after relevant documentation registration and approval the Units will receive the status of Radioactive Waste Management Facilities, similarly to ChNPP Unit 3. The status of “Nuclear Facility” will remain be applicable to Spent Nuclear Fuel Storage Facility (ISF-1), in which standard fuel from three ChNPP Units is stored.

New status of the Units will allow speed up and extend work in terms of the Units equipment dismantling and Chernobyl NPP decommissioning. This will provide a possibility to reduce operating costs, and therefore the burden on the State Budget of Ukraine, from which Chernobyl NPP is funded.
