It's cost-efficient to operate in profitable scenarios and halt in costly scenarios.
Optimizing profitability concerns the full operating range, not same anecdotal outliers.
All energy-intensive industry operates only when circumstances are favorable. Sometimes it's more profitable to reduce output temporarily, e.g. during high gas-prices, or during weekends when workers are more expensive.

That really depends. You have fixed costs to operating a nuclear plant. You can't suddenly operate for a smaller fraction of the time and expect the economics of operating the plant to be the same.
Also, your comment was about the technical design of the plant and how it used flow to cool things, not the decision to turn lower operational output.
