How nuclear power saved Armenia

    From the article, published a year ago:

    An environmentalist movement sprang up, calling for the shutdown of the Metsamor reactors. The authorities backed down, and the two reactors were turned off on February 25 and March 18, 1989.

    ...

    As the Armenian government supported the Nagorno-Karabakh secessionists, Azerbaijan retaliated by shutting off some of the natural gas pipelines that led to Armenia. In a sense, Azerbaijan’s authorities did to Armenia what Russian President Vladimir Putin is now doing to Western European countries that support Ukraine’s war effort. With its nuclear reactors and natural gas supply shut down, Armenia was left with a reduced capacity to generate electricity.

    ...

    Then came the winter of 1992–1993. Mountain rivers froze, hydroelectric dams dried up, and suddenly hydropower too was nearly gone. Armenia was getting barely a trickle of electricity. What followed is a period now known in Armenia as “tsurt u mut tariner,” literally the cold and dark years: severe shortages of electricity, freezing concrete apartment complexes, closed schools, and many other disruptions. The economy collapsed, with Armenia’s gross domestic product contracting by an estimated 50 to 80 percent between 1990 and 1993. Then, a massive exodus followed, shrinking Armenia’s population by a quarter in just a few years.

    ...

    Understanding their mistake, the Armenian authorities re-evaluated their past decision. The choice was stark: Either indulge in exaggerated fears of radiation and face unpredictable consequences, or sober up and accept nuclear power as a lesser evil. Ultimately the government chose the sober option. But rather than rushing headfirst to hastily restart the Metsamor nuclear power plant, the authorities decided to make significant safety improvements to the reactors.

    One of the Metsamor reactors finally restarted on November 5, 1995, just before the winter season. The desperately needed 400 megawatts flowed again into the small country’s languishing power grid. Almost overnight, lights were turned on, water pumps worked again, and industries revved up to capacity. Children like my sister and I stopped their exhausting routine and Armenia became a net exporter of electricity.

    ...

    Despite its important contribution to the electricity mix, the nuclear power plant at Metsamor is not without problems. Mainly, like most Soviet-era PWRs, the reactor does not have the external containment building that is common with Western designs. It is also an aging machine. Because of Armenia’s growing energy needs, the Metsamor reactor has been issued multiple lifetime extensions. Based on current plans, Metsamor’s VVER-440 reactor will shut down permanently by 2036. Meanwhile the Armenian government has been busy exploring replacement alternatives, such as possibly US-built small modular reactors (SMRs), seen as a viable replacement.
