Table 3: Electricity Production in Bulgaria

Electricity Production (1996 est.)41.6 billion kWh
Electricity Consumption per capita (1996 est.)5,000 kWh
Total Installed Generating Capacity (1996)12,000 MW
Thermal-Fired Plants 7,400 MW (62%)
Nuclear Plants 3,760 MW (31%)a
Hydroelectric Plants 840 MW (7%)
Nuclear Plant Operator National Electric Company
Nuclear Regulatory Authority Committee on the Use of Atomic Energy for Peaceful Purposes
a According to International Nuclear Safety Program at Pacific Northwest National Laboratory, "[I]n 1997, nuclear power supplied 45 percent of the country's electricity. However, at times that share has often risen to nearly 50 percent because fossil fuel power plants and hydropower plants have not achieved expected outputs." (http://insp.pnl.gov:2080/?profiles/ceec/bulgaria_intro)

Note: In order to operate reliably without blackouts and brownouts, an electric power system needs roughly 20 percent capacity above its peak load.

Unit 6 VVER-1000 910 MWe 6/1991 12/1993
Reactor Supplier: Atomenergoexport (USSR)
Type of Reactors: Pressurized Water
Moderator: Light Water
Fuel: Low Enriched Uranium
Fuel Supplier: Russia
Spent Fuel Management: Storage. In the past spent fuel
has been sent to Russia for reprocessing. A new agreement
on reprocessing is being held up by disputes over
pricing and shipment routes as well as due to opposition.
