While the synthetic elements do not naturally occur on Earth, it is thought that they may have been present at one time, but have since disappeared due to their instability and short half-lives. This suggests use for curium as a power source. Man-made lava is a real thing and it is created in one of the most dangerous situations known: during the reactor core meltdown of a nuclear power plant.

To start the fission process in a reactor a steady supply of neutrons is needed. While some are named after the place where they were discovered (americium and californium ), most of these elements are named after the scientist who discovered them (einsteinium, curium, mendelevium, etc). Account. It can be found in spent nuclear fuel. Curium is a transuranic element. Curium has allowed us to better understand and cleanse our accounting and trading system data and also provides a visible reassurance that … The location of the research was at University of California, Berkeley.
