Bohunice nuclear power plant in context
By gross operating capacity Bohunice nuclear power plant is the 2nd largest of 2 operating nuclear sites in Slovakia, holding 40% of the country's operating capacity, and ranks 149th of 172 worldwide.
Its operating units started up in 1985; the median unit is 41.0 years old, older than the median of 28.0 in Slovakia.
The 5 units with both construction and grid dates on record took 6.6 to 14.4 years (median 7.9) from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 years.
The nearest other tracked nuclear sites are Mochovce nuclear power plant (62 km), Dukovany nuclear power plant (131 km) and Paks nuclear power plant (231 km).
Build time by unit
| Unit | Construction start | Grid connection | Years | Fleet median, same decade |
|---|---|---|---|---|
| Unit A1 | 1958 | 1972 | 14.4 | 5.4 (1970s) |
| Unit 1 | 1972 | 1978 | 6.6 | 5.4 (1970s) |
| Unit 2 | 1972 | 1980 | 7.9 | 7.3 (1980s) |
| Unit 3 | 1976 | 1984 | 7.7 | 7.3 (1980s) |
| Unit 4 | 1976 | 1985 | 8.7 | 7.3 (1980s) |
Nearest tracked nuclear sites
| Site | Country | Distance | Operating GW gross |
|---|---|---|---|
| Mochovce nuclear power plant | Slovakia | 62 km | 1.5 |
| Dukovany nuclear power plant | Czech Republic | 131 km | 2.0 |
| Paks nuclear power plant | Hungary | 231 km | 2.0 |
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.

Magnitude 4.0 and above within 200 km of Bohunice nuclear power plant's listed coordinates, past 30 days. This is distance, not shaking: it says nothing about damage or any change in operation. Every plant.
| Location | Trnavský, Slovakia |
|---|---|
| Coordinates | 48.4968, 17.6907 |
| Elevation | about 170 mabove sea level |

| Units by status | Operating: 2 Retired: 3 Pre-construction: 1 |
Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
