Current concept of NPP power unit preparation for decommissioning

▪ Deferred dismantling is determined for the following NPP'sunits*:

– Novovoronezh NPP, Units Nos. 1, 2

– Kola NPP, Units Nos. 1‐4

– Bilibino NPP, all Units

▪ An approach is adopted to multiunit NPP decommissioning,where the first NNP unit, located on the site, isdecommissioned under deferred dismantling option:

– Balakovo NPP, Unit No. 1

– Kalinin NPP, Unit No. 1

– Rostov NPP, Unit No. 1

▪ For all other units, including RBMK, the concept "immediatedismantling" decommissioning option is adopted.

For the majority of NPP units decommissioning is

determined under "immediate dismantling" strategy

‐ construction of diesel fuel base stock of 16.0 thousand tons, including self‐contained powersource (2017)‐ construction of a backup diesel‐generator station with the capacity of 8.9 MW (2017)‐ construction of 110/35/6 kV substation and 6 kV VL‐6 "Bilibino 1. NPP ‐ "Dam" (2017)

‐ implementation of comprehensive engineering and radiation survey of unit 1 (2016)‐ developing a set of supporting documents for obtaining a license to operate unit 1 after the finalshut down (2016)‐ development of decommissioning project for units No. 1, 2 for the period of up to 2019 (2019)‐ removal of leaky spent fuel assemblies from unit No. 1 (2018)

‐ Design documentation has been developed‐ works are carried out to prepare for the removal of spent nuclear fuel and for decommissioning(individual decisions)

‐ dismantling works were carried out in unit 1 turbine building‐ surface decontamination of machine pile drainage montejus boxes' equipment is carried out‐ radioactive waste, produced at gasholder accidents' localization, is removed

‐ Decommissioning project is developed‐ 8 turbine units and 1st unit deaerator stack equipment are dismantled‐ 1 and 2 units of Novovoronezh NPP are signed off to Pilot Demonstration Engineering Center fordecommissioning branch‐ decommissioning works are carried out since 2015, after obtaining a decommissioning license

NPP Unit Operation

Ensuring minimum cost of NPPs units decommissioning works

• Implementation of "immediate dismantling" strategy

• Operational configuration• Start of decommissioning works after unit shutdown under individual technical solutions

• Regulatory framework improvement

• Rapid removal of spent nuclear fuel
