The Prairie Island nuclear power plant near Red Wing is getting extra inspections from the federal government, after a delay in repairing a radiation detector.
A radiation detector in Prairie Island's Unit 1 stopped working in July 2011. Minnesota Public Radio News (http://bit.ly/XcYQmp) reports the detector was not repaired for 10 months.
Although other detectors were still operating, the Nuclear Regulatory Commission says the plant's ability to declare an emergency was degraded if one had occurred.
The commission says Xcel Energy Inc. has repaired the detector, returned it to service and taken corrective action to better assess emergency equipment failures.
In a statement, Minneapolis-based Xcel Energy says backup measures were in place and there was no danger to plant workers or the public.
