Piletas de peligro

WASHINGTON, DC – La crisis nuclear de Fukushima Daiichi en Japón ha resaltado los peligros de almacenar combustibles gastados de alto nivel radioactivo en piletas de agua que son susceptibles a rupturas causadas por desastres naturales y explosiones de hidrógeno ocasionadas por accidentes. La crisis debería servir como un llamado de atención para que los gobiernos y la industria tomen acciones que puedan reducir los riesgos del almacenamiento de combustibles gastados.   

Desafortunadamente, el almacenamiento de estos combustibles ha sido “un pensamiento tardío” tal como dice Ernest Moniz, director de la Iniciativa Energética del MIT. En docenas de países, se han guardado decenas de miles de toneladas de material altamente radioactivo en edificios que apenas cumplen con las protecciones rigurosas habituales que tienen que ver con el material radiactivo en el núcleo de los reactores.  

Las piletas se han sobrecargado en muchos países, debido a la falta de depósitos permanentes para los desechos nucleares. Ningún país ha abierto un depósito de estas características, sólo Suecia ha avanzado de manera significativa en este sentido.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
