Like catastrophic global climate change, the nuclear age expands the circle of the “lost” objects to be mourned from the human to microbial, vegetal and animal ecosystems, clean water, soil and atmosphere, all the way to the ideas and beliefs in personal and national safety, self-suffi- ciency, and sovereignty.
Still, nuclear materials and effects are unique: at the extreme, they annihilate time itself. Their interference with the heterogeneous temporalities of living beings, communities, and environ- mental forces is derivative with regard to their negation of time. For instance, depleted urani- um has a half-life of 4.468 billion years, in the case of U-238, or 700 million years, in the case of U-235, which, to all intents and purposes, approaches an eternity.
Since the nuclear object does not pass away, refusing to become the past, it weighs heavily on the present it tears out of the order of time. With this, it is converted into a material embodi- ment of trauma, psychic as much as planetary, a statically traumatic present and presence that cannot be metabolized, “digested” so as to open up the future.
How does one mourn a loss that resists passing away, that repels the past and the future alike? Nuclear energy generation and the disasters associated with it, the liquid and solid residues of power plants’ “successful operations,” military testing of atomic weapons, and the consequenc- es of their deployment confront us with an object of mourning that, due to its mode of being and temporality, thwarts mourning’s work.
