It is the country's aging nuclear facility that currently concerns Armenian environmental groups as well as those in neighboring countries. Twenty miles west of the capital Yerevan, Armenia's Metsamor Nuclear Power Plant was built in 1970s and houses two VVER-440 Model V230 nuclear reactors. Metsamor, which currently produces about 40 percent of the country's electricity, is located in a seismically active zone and was closed even before the 1991 collapse of the Soviet Union because of the devastating Dec. 7, 1988, earthquake in Spitak.
If you go forty miles west of Yerevan, then backtrack ten miles, twice in a row, you'll find the plant.
