Balakovo NPP participates in a twinning program between nuclear power stations in Europe and Russia; since 1990 it has been in partnership with Biblis Nuclear Power Plant.
Reactor data
The Balakovo Nuclear Power Plant has four operating units:
In 2018 Rosatom announced it had developed a thermal annealing technique for reactor pressure vessels which ameliorates radiation damage and extends service life by between 15 and 30 years. This had been demonstrated on unit 1.

Incidents
On 27 June 1985 during startup of the first reactor unit, a human error (later attributed to inexperience and haste) unexpectedly opened a pressurizer relief valve, and steam entered the staff work area. Fourteen people were killed. This event is cited as one of the predecessors of the Chernobyl disaster.
