Plutonium from nuclear fuek is stabilized by which of the following:

Options

A. `O_2F_2`
B. `I_2O_5`
C. `ClF_3`
D. `BrF_5`

Answer

To solve the problem of which compound is used to stabilize or remove plutonium from spent nuclear fuel, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Spent Nuclear Fuel**:
- Spent nuclear fuel refers to nuclear fuel that has been irradiated in a nuclear reactor and is no longer efficient in sustaining a nuclear reaction. It contains various radioactive isotopes, including plutonium.

**Hint**: Recall that spent nuclear fuel contains isotopes that have undergone fission in a reactor.

2. **Identify the Compounds**:
- The options provided are:
- I2O5
- O2F2
- ClF3
- BrO3

**Hint**: List the compounds and consider their chemical properties related to halogens and fluorine.

3. **Research the Extraction Process**:
- The extraction of plutonium from spent nuclear fuel typically involves chemical reactions that can form stable complexes with plutonium.

**Hint**: Look into the chemistry of plutonium and its reactions with halogens or fluorine-containing compounds.

4. **Analyze the Reaction with O2F2**:
- O2F2 (dioxygen difluoride) is known to react with plutonium to form plutonium hexafluoride (PuF6), which is a complex that can be separated from other materials in the spent fuel.

**Hint**: Consider how fluorine compounds are often used in the extraction of actinides like plutonium.

5. **Conclusion**:
- Based on the reaction, O2F2 is the compound that effectively stabilizes and helps in the extraction of plutonium from spent nuclear fuel. Therefore, the correct answer is O2F2.

**Final Answer**: The compound used to stabilize plutonium from spent nuclear fuel is **O2F2**.
