The use of nuclear energy has two very serious inherent problems these are :-
(A) Accidental leakage
(B) Safe disposal of radioactive waste
(C) Global warming
(D) Green house effect

Options

A. A, B
B. A, C
C. A & D
D. C, D

Answer

To solve the question regarding the serious inherent problems associated with the use of nuclear energy, we will analyze the options provided and identify the correct answers step by step.

### Step 1: Understand the context of nuclear energy
Nuclear energy is often considered a cleaner alternative to fossil fuels for electricity generation. However, it comes with its own set of challenges and risks.

**Hint:** Consider the potential risks and consequences associated with nuclear energy.

### Step 2: Analyze the options given
The options presented are:
- (A) Accidental leakage
- (B) Safe disposal of radioactive waste
- (C) Global warming
- (D) Greenhouse effect

**Hint:** Think about the historical incidents related to nuclear energy and the types of waste it produces.

### Step 3: Identify the serious problems
1. **Accidental Leakage (A)**: This refers to incidents where nuclear material is accidentally released into the environment. Notable examples include the Three Mile Island accident and the Chernobyl disaster. These incidents highlight the risks associated with nuclear power plants.

2. **Safe Disposal of Radioactive Waste (B)**: After nuclear energy is generated, it leaves behind radioactive waste that poses significant disposal challenges. The waste remains hazardous for thousands of years, and finding safe methods to store or dispose of it is a major concern.

**Hint:** Recall any historical accidents or challenges related to nuclear waste management.

### Step 4: Eliminate the incorrect options
3. **Global Warming (C)**: This is primarily associated with greenhouse gas emissions from burning fossil fuels, not nuclear energy. Nuclear power does not produce greenhouse gases during operation.

4. **Greenhouse Effect (D)**: Similar to global warming, this is related to the accumulation of greenhouse gases in the atmosphere, which is not a direct issue with nuclear energy.

**Hint:** Consider the definitions and causes of global warming and the greenhouse effect.

### Step 5: Conclusion
The two serious inherent problems associated with nuclear energy are:
- (A) Accidental leakage
- (B) Safe disposal of radioactive waste

Thus, the correct answer is options (A) and (B).

**Final Answer:** (A) Accidental leakage and (B) Safe disposal of radioactive waste.
