But was this car a barn find? At least we know that even with a nuclear car a rod ejection is a bad thing. Well, this is boron, I've got to SCRAM.
barn: Unit of cross-sectional area of nuclei (equivalent to 10^-24 cm2), coined at Purdue in 1942. There is, also, a smaller version: the shed (10^-48 cm2).
rod ejection: Type of accident scenario where a control rod is "removed" from the reactor
boron: Element that is a strong neutron absorber, used to "poison" (slow down) some reactors quicky under accident scenarios.
SCRAM: Safety Control Rod Axe Man - emergency shutdown of reactor
