Questions and Answers
What is the advantage of using graphite as a medium in reactor cores?
What is the disadvantage of using graphite reactors for burning plutonium?
Why is predicting the behavior of neutrons in graphite challenging?
Study Notes
- Graphite is a homogeneous and diffusive medium used in reactor cores.
- Neutrons can travel further in graphite due to its longer mean free path.
- Graphite reactors have a slightly harder spectrum than LWRs.
- Graphite reactors are good at burning plutonium but can have a high buildup of minor actinides.
- High Temperature Gas Cooled Reactors use graphite components as moderators.
- Predicting the behavior of neutrons in graphite is challenging due to its large mean free path.
- Accurately modeling graphite behavior requires discretization and coupling to thermal fluidics.
- Graphite is effective at slowing down neutrons and is low cost and widely available.
- A harder spectrum can result in a more negative temperature feedback.
- Graphite remains an important moderator material in many types of nuclear reactors.
