Flood Threat To Nuclear Plants Covered Up By Regulators, NRC Whistleblower Claims

In a letter submitted Friday afternoon to internal investigators at the Nuclear Regulatory Commission, a whistleblower engineer within the agency accused regulators of deliberately covering up information relating to the vulnerability of U.S. nuclear power facilities that sit downstream from large dams and reservoirs.

The letter also accuses the agency of failing to act to correct these vulnerabilities despite being aware of the risks for years. . . . (more)

Reactor Shuts Down Unexpectedly at Prairie Island Nuclear Plant Monday

Unit 2 of Minnesota’s Prairie Island nuclear plant shut down automatically Monday morning, according to Nuclear Street sources.

Safety systems for the reactor tripped at 7:22 a.m., sources indicate. The unit shut down safely, the plant responded as expected, and no injuries were reported. The cause of the trip is under investigation. It appears to be a weather-induced generator lockout, sources said, and one possibility is that lightning struck a power line leading to a plant substation.

Operated by Xcel Energy 28 miles southeast of Minneapolis, Minn., Prairie Island uses two, roughly 550-megawatt Westinghouse pressurized water reactors licensed in 1974, according to the Nuclear Regulatory Commission. Unit 1 at the plant was shut down April 29 for scheduled refueling.

According to an NRC reactor-status list, unit 2 was operating at full power when the trip occurred.
