Thoroughly assess the risk of tsunami before building nuclear power plant

Deputy General Director of ROSATOM Group (Russia) - the unit that directly helps Vietnam build Ninh Thuan 1, said: "Basically, the location that Vietnam has chosen (Ninh Thuan) is satisfactory. However, Vietnam Men need to assess, re-evaluate carefully the factory construction site because the risks can still occur '.

>> 'Ninh Thuan nuclear power will be secured'

Vietnam's first nuclear power plant - Ninh Thuan 1, has been warned to lie on a geological fault zone, at risk of tsunamis. Therefore, at the seminar organized by Vietnam Atomic Energy Institute on May 31 and June 1, Russian experts - partners helping Vietnam build Ninh Thuan 1, said that Vietnam needed Thoroughly survey the plant construction site. The selection of another location will be investigated if Ninh Thuan does not meet the safety criteria for plant operation.

Model of Russian nuclear power plant is expected to be built in Ninh Thuan.

Consider carefully the plant construction site

The project to build Vietnam's first nuclear power plant was approved by the National Assembly on November 25, 2009 with a total investment of up to $ 12 billion. Ninh Thuan 1 is expected to build in Phuoc Dinh commune (Thuan Nam), Ninh Thuan 2 is built in Vinh Hai commune (Ninh Hai). Ninh Thuan 1 will start construction in 2014, bring the first unit to operate commercially in 2020. However, before the start of construction, Vietnamese scientists have warned about the sea area at risk of tsunami. high, running from Da Nang to Ninh Thuan - the construction site of the factory. According to calculations, earthquakes of more than 6.5 magnitude in coastal areas are at risk of causing tsunamis.

For the central provinces, the risk of tsunamis can come from the fault zone of 109-110 meridians in the East Sea or the Manila subduction zone (Philippines). The 109-110 fault zone is very deep and long, can cause earthquakes in the areas of Quang Nam, Quang Ngai, Ninh Thuan, Khanh Hoa . Ninh Thuan is located at an altitude of 300m above sea level. Plant construction location is also expected near the coast. If the earthquake in Manila submerged zone will be able to spread to Vietnamese waters and cause tsunami 10m high. Then, if the nuclear power plant located near the sea will pollute the spread of radiation in seawater.According to scientists, if the factory is still built in Ninh Thuan, it is necessary to ensure the anti-seismic design of level 9 - the highest level.

At the seminar, Mr. Boyarkin Sergei - Deputy General Director of ROSATOM Group (Russia) - the unit that directly helped Vietnam build Ninh Thuan 1, said: "Basically, the location that Vietnam chose (Ninh Thuan) However, Vietnam needs to assess and reassess the site of the plant construction because of the risks that can still occur.According to Russian experience, the location of the nuclear reactor personnel must be strong, away from the geological fault zones and must be protected to avoid the effects of tsunamis.After calculating and testing the design of the factory many times in specific conditions in Ninh Thuan, The construction will begin in 2014. During the construction period, Russian experts will help Vietnam monitor and ensure proper construction. , achieving the highest safety performance ".

Meanwhile, Dr. Le Van Hong - Deputy Director of the Institute of Atomic Energy Vietnam - affirmed: " Ninh Thuan is currently only the expected location. Next time, the Institute's expert team will combine with Geological experts of Russia conduct surveys and re-evaluate geological factors in Ninh Thuan, if they meet the standards and standards, they will continue to build. The final decision right belongs to the Prime Minister ".

Russian technology will help Vietnam limit risks

Russia was selected as a strategic partner to help Vietnam build Ninh Thuan 1 Factory, directly participating in the Rosatom Group. Explaining the choice of Russian technology, Dr. Hong said: "Russia's nuclear technology has a long history of development, among the world's leading advanced countries. Russia has its own source technology. All can be transferred to Vietnam without going through intermediaries'.

Model of Russian nuclear power plant is expected to be built in Ninh Thuan.

' Vietnam decided to select pressure water boiler technology, belonging to the third generation of Russian reactors. This is the most modern technology in the world today, safety is of international standard. However, the technology of pressure water furnace also has many different design versions. Most commonly, Russia often transfers to design foreign countries 91 (operating China), design 92 (India, Bulgaria under construction), most recently the 96 design (currently only available in Russia ) ".

" Vietnam is still considering which design options, to ensure a balance between safety and economic factors. The higher the safety, the greater the cost. Russian technology will also help treat the entire waste. the nuclear generated by the plant, with a technology system that is the most advanced in the world "
