YEREVAN (RFE/RL)—Armenia’s Medzamor nuclear power plant poses an “acceptable” level of risk to environment and can “in principle” operate beyond its design life span, international nuclear safety experts said on Thursday following a two-week inspection conducted there.
While identifying several “good plant practices” at the Soviet-era facility, the experts working under the aegis of the International Atomic Energy Agency (IAEA) recommended specific measures which they said would further boost its operational safety.
“There is no industrial activity that does not pose any risk, but I think the results of our inspection show that this risk [at Medzamor] is acceptable,” Gabor Vamos, head of the IAEA’s ad hoc Operational Safety Review Team (OSART) for Armenia, told a news conference in Yerevan.
The Armenian government solicited the OSART mission about two months ago, citing the need to learn lessons from the grave accidents at Japan’s Fukushima Daiichi nuclear plant. It also hoped to ally renewed domestic and international concerns about Medzamor’s safety.
Like Japan, Armenia is situated in a seismically active region prone to powerful earthquakes. Local environment protection groups say the Fukushima disaster should be a wake-up to the authorities in Yerevan to shut down the Medzamor plant as soon as possible.
Armenian government officials and nuclear experts dismiss such concerns. One of their arguments is that the plant has undergone numerous safety upgrades since one of its two reactors was reactivated in 1995.
The OSART mission that arrived in the country on May 15 comprised 11 experts representing the IAEA, the European Union, as well as eight individual countries, including the United States, Britain and France. They spent two weeks inspecting Medzamor’s reactor and other facilities, assessing the plant’s safety and maintenance procedures and interviewing its personnel.
Vamos, who is from Hungary, said his team has submitted its preliminary findings to the Armenian government and will release a final report within three months. He said they contain three dozen proposals and recommendations and seven “good plant practices” that will be recommended to the nuclear industries of other nations for consideration.
According to Vamos, one of those examples is the fact that the Medzamor staff take wide-ranging safety measures on their own without relying on private contractors, as is the case in many nuclear plants.
The IAEA stressed this fact in a separate statement issued on Thursday. “This unique approach resulted in staff acquiring deep knowledge and skills to successfully operate and maintain new equipment,” it said.
The statement also said, “The plant has developed a specific, comprehensive system supported by procedure to mitigate the consequences of a station blackout by providing power to systems and components necessary for cooling the reactor in emergency conditions.”
On the downside, Vamos noted that Medzamor technicians do not quickly identify all equipment deficiencies that require urgent repairs. The Armenian authorities should work out a more rigorous mechanism for keeping the plant’s equipment in an “ideal state,” he said.
“The [Medzamor] administration expressed a determination to address all the areas identified for improvement and requested the IAEA to schedule a follow-up mission in approximately 18 months,” read the IAEA statement.
The Vienna-based nuclear watchdog also stressed that the OSART mission to Armenia was not a full-fledged “regulatory inspection.” “Nor is it a design review or a substitute for an exhaustive assessment of the plant’s overall safety status,” it said.
Medzamor’s sole functioning reactor generates about 40 percent of the country’s electricity. The EU classified VVER 440-V230 light-water reactor in the 1990s as one of the “oldest and least reliable” of 66 such facilities built in the former Soviet Union and Eastern Europe.
The Armenian government has pledged to decommission it by 2017, in time for the construction of a new and more powerful nuclear plant at the same site over 30 kilometers west of Yerevan. Work on that ambitious project was supposed to start in 2012.
However, the head of Armenia’s State Committee on Nuclear Safety, Ashot Martirosian, indicated last August that the construction could be delayed by several years, suggesting that the existing reactor will function longer than planned.
Asked to comment on such possibility, Vamos said, “There are examples in the world of nuclear reactors, including VVER-440 reactors, having their life spans extended, but to our knowledge, there is no official plan yet to prolong the exploitation of the Armenian Nuclear Power Plant,” “Therefore, that issue was not considered during our inspection.”
“But in principle, there is such technical possibility,” added the Hungarian nuclear expert.
Note that the Russians are in total control of this facility. There’s no way that they, or anyone else for that matter, would EVER trust Armenia (or an Armenian) with a nuclear facility or nuclear material!!
whats wrong with you, armenians run the whole thing
even though i support the dismantling of metzamor, im proud that armenia requested the iaea inspection and the follow up 🙂
Hope they ban this dirty nuclear energy and power planet! It is really dangerous! Look at Japan(Fukushima) look at Chernobyl disaster! Armenia is small country and it is more dangerous for us. Do not forget Armenia is not a developed country and a nuclear disaster would erase our nation!
The Armenian government should force the big mouth Europeans to put their money where their mouth is and help Armenia close this nuclear power plant and build a new nuclear powerplant using seismic base isolators which can prevent damage to the nuclear power plant in the case of an earthquake. Base-isolated nuclear power plants have been built in earthquake prone areas. The Tsunami did the major damage to the Fukushima-Diachi power plant by knocking out the electrical systme which powers the water pumps which force water through the nuclear core and send it to the turbine in the form of steam which generates the electricity. Armenia obviously has no risk of Tsunami’s so a well built nuclear power plant that is well run can be safe.
