U-235 content in enriched uranium, that is normally used in power reactors (e.g., at Tarapur atomic power plant), is about _____________ percent?
Correct answer: C. 3
- A. 85
- B. 50
- C. 3
- D. 97
Explanation
Power-reactor fuel is commonly enriched to about 3% U-235, compared with roughly 0.7% in natural uranium. Values such as 85% or 97% correspond to highly enriched material, not normal power-reactor fuel.
