"California is battling federal authorities over how to clean up a contaminated former nuclear research site near Simi Valley that was also caught up in the flames of November’s Woolsey Fire.

The fire complicated cleanup efforts after burning large portions of the site, scorching nearly 100,000 acres of land, and destroying 1,643 buildings.

The Santa Susana Field Laboratory operated as a nuclear research and rocket test facility on 2,850 acres from 1948 to 2006. Ten nuclear reactors were used on the site for various research products, and a partial meltdown in 1959 was not revealed until 20 years later."
