RECYCLING OF NUCLEAR POWER: RESERVOIR
SOMETHING FOR THE DEBATE, THE IMMEDIATE ATTENTION OF PART OF CITIZENS:
VIOLA AGAIN HERE IS ALSO GENERAL ENVIRONMENTAL LAW N ° 25,675
WILL KNOW THE CALL FOR PUBLIC HEARINGS? ;
"ENVIRONMENTAL IMPACT ASSESSMENT EIA ENVIRONMENTAL IMPACT STUDY - EIS?
Or ONLY WILL BE AS SIMPLE ENERGY CONSUMERS?
JUAN CARLOS A. PAESANI
postpone by one year the Nuclear stop
The work to extend the life of Central would be detained for almost two years. By several factors, not be carried out in 2011.
The Central Nuclear Embalse, with its aging reactor and should be out of service after 26 years of activity. The national government decided -And-launched a plan to dismantle the plant not only to prolong its life for another 25 years.
For that, you must stop its progress for at least a year and a half, to allow the construction of replacement of all critical sectors. Although three years ago it was announced that 2011 was the most likely date stopped, it is almost certain that this step will be delayed by at least one year. Several sources
embalseña plant admitted that "it seems ruled" out of service for this year. In addition, an official of Nuclear Argentina Sociedad Anónima (NASA), the state company that manages nuclear power plants, confirmed to this newspaper that while "the date is not determined and depends on a number of factors," is probably not in 2011.
In the query whether the events in Japan could cause actual plans nuclear expansion underway in Argentina, the same official replied: "No way." Ruled out the possibility of opening a debate like the one developed for these days around the world, on the desirability of continuing the nuclear program or at least review the safety guidelines. The expansion plans include extending the life of the Embalse, completion of Atucha 2 and then construction of the fourth nuclear power plant in Argentina that would Atucha 3.
From Nasa, was identified as likely to Atucha 2 start generating power in early 2012. That would be one of the reasons that it would wait to get service reservoir, preventing its absence impact the country's energy demand. The Cordoba plant provides more than four percent of that total.
already started. actually works for the "recycling" of the plant Calamuchita began three years ago, with tenders for equipment, project design and adequacy of facilities. In 2009, Congress approved almost unanimously endorsed the project.
Ricardo Sainz, project manager life extension, he said, to start this process, that between the old and the new plant there would be differences in technology, "but parts and modifications to improve material conditions and security components. " Sainz said that life ends with the wear of critical material, especially in the nuclear reactor. "The design determines a lifetime, according to their materials and components, and checked thoroughly to when they can work," he said.
"The moment you stop working does not depend on a decree, but the analysis of systems. Everything is specified. When it reaches its limit, this material can not go, period, "he said. Sainz
detailed at the time that the critical material change "is the core of the reactor and all its internal components, in addition to" the four steam generators and other equipment and instruments. "
The Nuclear has stops maintenance and inspection of several weeks each year and a half. The last, months ago, was somewhat longer because it had changed three of the 380 channels of the reactor, which were identified as affected.
The life extension cost about one billion dollars. In the company indicate that represents half the cost of a new plant with similar characteristics.
Also, in defense of the project argue that a proper and safe dismantling demand an outlay almost similar, but losing in that case the country a key source of energy, and there are few experiences in this respect for plants of this size.
