Smolensk nuclear power plant in context
By gross operating capacity Smolensk nuclear power plant is the 7th largest of 10 operating nuclear sites in Russia, holding 10% of the country's operating capacity, and ranks 40th of 172 worldwide.
Its operating units started up between 1983 and 1990; the median unit is 41.0 years old, older than the median of 37.5 in Russia.
The 3 units with both construction and grid dates on record took 5.7 to 9.0 years (median 7.2) from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 years.
The tracker lists a planned retirement year, a forecast and not a decision on record, for 3 operating units: Unit 1-1 (2034), Unit 1-2 (2034) and Unit 1-3 (2034).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit 1-1 | 1975 | 1982 | 7.2 | 7.3 (1980s) |
| Unit 1-2 | 1976 | 1985 | 9.0 | 7.3 (1980s) |
| Unit 1-3 | 1984 | 1990 | 5.7 | 8.0 (1990s) |
How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.
