Overview - First S

Some Background B k d

  • US nuclear reactors use uranium enriched fuel assemblies to produce the heat necessary to make electrical power
  • Approximately every 18 - 24 months, roughly 1/3rd of the nuclear fuel assemblies are replaced
  • The fuel removed from the reactor is called spent fuel and is required to be cooled after the reactor is shutdown because it still generates heat (called decay heat) 5

Decay Heat

  • Fuel assemblies continue to produce heat after shutdown
  • This heat is called decay heat
  • Decay heat is a very small fraction of the heat produced when compared p p to the total heat produced by an operating reactor
  • Decay heat gets smaller over time 6

Why y ISFSI?

- Spent fuel pool

- Independent Spent Fuel Storage Installation (commonly called an ISFSI)

  • Both methods are strictly regulated to ensure safety
