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?
- Methods M th d tto safely f l store t spentt nuclear l fuel f l include:
i l d
- Spent fuel pool
- Independent Spent Fuel Storage Installation (commonly called an ISFSI)
- Both methods are strictly regulated to ensure safety
- As a facility runs out of room in their spent fuel pool, the fuel is moved to an NRC licensed ISFSI 7
