converter reactor: meaning, definition, pronunciation and examples
C1/C2Technical/Scientific
Quick answer
What does “converter reactor” mean?
A nuclear reactor designed specifically to convert non-fissile material (such as thorium-232 or uranium-238) into fissile fuel (such as uranium-233 or plutonium-239) for use in other reactors.

Meaning and Definition
A nuclear reactor designed specifically to convert non-fissile material (such as thorium-232 or uranium-238) into fissile fuel (such as uranium-233 or plutonium-239) for use in other reactors.
A reactor in which fertile material is placed to be transmuted into fissile material, often as part of a fuel breeding cycle. In a broader technical context, it can sometimes refer to chemical process reactors designed to convert feedstock, but its primary and most specific meaning is within nuclear engineering.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Spelling follows national conventions ('converter' is more common in both, though 'convertor' is a rare BrE variant).
Connotations
None beyond the technical definition.
Frequency
Equally low-frequency and confined to specialist nuclear engineering texts in both varieties.

Common Mistakes When Using “converter reactor”
- Using 'converter reactor' to mean any reactor that generates electricity (a power reactor).
- Confusing it with a 'breeder reactor', which has a breeding ratio >1.
- Misspelling as 'convertor reactor' (uncommon).
FAQ
Frequently Asked Questions
No. A breeder reactor produces more fissile material than it consumes (breeding ratio >1). A converter reactor has a conversion ratio of less than 1, meaning it produces some new fuel but not enough to fully replace what it uses.
Yes, most converter reactors are also power reactors. They generate heat (and thus electricity) from the fission of their initial and converted fuel, but their defining characteristic is the fuel conversion process.
Thorium-232 is a common fertile material placed in a converter reactor to be transmuted into the fissile uranium-233.
No. 'Converter reactor' is a highly specialised term in nuclear engineering. For general purposes, the word 'reactor' alone, or 'nuclear reactor', is sufficient.
A nuclear reactor designed specifically to convert non-fissile material (such as thorium-232 or uranium-238) into fissile fuel (such as uranium-233 or plutonium-239) for use in other reactors.
Converter reactor is usually technical/scientific in register.
Converter reactor: in British English it is pronounced /kənˈvɜːtə riˈæktə/, and in American English it is pronounced /kənˈvɜːrt̬ɚ riˈæktɚ/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a 'currency converter' but for nuclear fuel: it changes one type of atom (fertile) into another, more useful one (fissile).
Conceptual Metaphor
A FACTORY/REFINERY FOR ATOMS (It transforms raw atomic material into a usable fuel product).
