Passage Summary: Even though nuclear fuel is cheap, building the plants costs so much that they aren't worth the money compared to coal or oil.

Conclusion: Nuclear power plants are not a financially viable option, even if we ignore safety concerns.

Reasoning: Although the fuel for nuclear power is cheaper than coal or oil, the initial cost to build nuclear plants is much higher than that of conventional plants.

Analysis: The argument concludes that nuclear power is economically unfeasible based on a comparison of two specific costs: fuel and construction. To strengthen this, we need to ensure that the high construction costs aren't eventually offset by the low fuel costs over the plant's lifetime. Look for an answer that suggests the total long-term expenses of nuclear power remain higher than conventional alternatives. It would also be helpful to find evidence that other hidden costs, like maintenance or waste disposal, further tip the scales against nuclear energy.
