The Nuclear Regulatory Commission says it has questions about Exelon Generation's plan for handling a big flood at the Dresden Nuclear Station in Morris. The commission says recent inspections raised concerns about whether the current plans are adequate in the event of a catastrophic flood like the one that swamped the Fukushima Dai-ichi plant in Japan last year. Among the questions is how the company would reach the plant to refuel a diesel pump that would circulate water to cool the reactor. The company has 30 days to respond. NRC spokeswoman Viktoria Mitlyng says the plan needs to address the worst possible flood, no matter how improbable. She says concerns with Dresden's plan don't represent an immediate safety risk.
