Enresa, the public company that will build the nuclear waste storage Villar de Cañas (431 inhabitants, Cuenca) recognizes one of its technical reports to the possible existence of "relevant geotechnical risks" that could lead to subsidence in the ground. The Technical Specification, posted on its website, collect greatest entity as endangered on the site "the existence of karst forms, developed in plaster." According to this document, it is a condition "of some significance unfavorable" and "non-negligible consequences". These casts could dissolve and generate soil subsidence and collapse. The same study, July 2012, highlights the presence of a sinkhole (more or less deep depression) "yesífera in the same formation in which the site is located."
The rising river Záncara, about 500 meters from the plot in providing lift the nuclear store has attracted in recent days many fears about the safety of the site. The water has reached a few meters of the land-from 300 to 1,000, according to estimates, and although the area has not been flooded, the Platform against nuclear cemetery that affects Basin geomorphological hazards, especially on the basis of casts, discouraged go ahead with the project at the risk of soil subsidence. These plasters can be dissolved in various ways, by infiltracón water from outside, or by panning, explained from the platform.
Surveys are made "every 30 meters" to know "for sure" what's on the ground, according to the president of the construction
Enresa president, Francisco Gil Ortega said on 27 November, during a hearing in the Congress of Deputies, who were doing surveys "every 30 meters" to know "for sure" what's in the ground, picks La Tribuna de Toledo. "Now is when we are doing a study to characterize the field because you could not do before," said one of the deputies, who asked for hydrogeological risk.
This Thursday, the PSOE of Castilla-La Mancha has released some images claiming that the land was flooded by the recent rains. The mayor of Villar de Cañas, Jose Maria Saiz (PP), Enresa, the public company in charge of building and Platform against infrastructure have limited the rafts around.
The planned construction stages as the river reaches a flow Záncara 3,000 cubic meters
The public company stresses that the fact that water has not reached the place where will be located the ATC stands for centralized temporary storage, shows that the area is not flooded. The company is completing the first phase of field studies and those who have done tastings terrain. Enresa Sources explain that there has been a previous study that drew flooding scenarios as the river had a flow Záncara 3,000 cubic meters (much higher than recorded). Even then, as the public company, the plot would not be affected.
This research will confirm whether the land is suitable for building the ATC. After detailed characterization begin "to develop specific engineering".
"The logic is that these studies were done before and not later" affects Carlos Villeta, coportavoz Platform Against Basin nuclear cemetery and member of Ecologists in Action. From the Platform emphasize that phenomena such as the formation of torques or sinkholes are "very fast", also remember that the land is situated at 2,000 meters from the town right on the border legislation establishing urban distance of these facilities .
In Enresa consider the atomic waste storage can be tailored "to almost any terrain" and entrusting the safety guidelines of the Nuclear Safety Council.
