2016 2 NPP units are shut down, 2 NPP units are being decommissioned
2028 13 NPP units are shut down, 4 NPP units are being decommissioned
10 years' readiness for massscale decommissioning of NPP units
VVER440 EGP6 RBMK1000 BN600
Deferred dismantling is determined for the following NPP'sunits*:
Novovoronezh NPP, Units Nos. 1, 2 Kola NPP, Units Nos. 14 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.
construction of diesel fuel base stock of 16.0 thousand tons, including selfcontained powersource (2017) construction of a backup dieselgenerator station with the capacity of 8.9 MW (2017) construction of 110/35/6 kV substation and 6 kV VL6 "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
Up to 90% of dismantled equipment should be decontaminatedand returned into economic turnover
The amount of reimbursable funds from metal sales equals up to10% of project cost
