scramfire

Scramfire is a term used primarily in speculative fiction to describe a dramatic energy discharge associated with a reactor scram or a specialized device designed to produce an intense flame or plasma burst. The word combines scram, short for automatic reactor shutdown, with fire, signaling a sudden, luminous event that follows a rapid energy transition. There is no standardized definition, and the concept varies by work.

In fiction and media, scramfire is often depicted as a controlled but highly energetic release of plasma or incendiary energy that occurs when a reactor is abruptly disabled or engaged to trigger a defensive or offensive effect. Depictions range from a bright, visible plume that disables electronics to a destructive jet that can breach armor. Some settings treat scramfire as a weaponized phenomenon created by specialized devices or by manipulating fusion or fission energy stores.

Real-world status: No device or phenomenon named scramfire exists in engineering practice; the term is a fictional construct used to convey dramatic energy release. It serves as a storytelling shorthand for rapid, high-energy events tied to reactor shutdown or energy manipulation.
