The NRC’s blog has a timely piece on how Grand Gulf, River Bend and Waterford are preparing for the rising floodwaters from the Mississippi River. Here’s what Grand Gulf is up to:
NRC’s resident inspectors at Grand Gulf have been monitoring preparations by Entergy workers. According to projections by the U.S. Army Corps of Engineers, the plant should be able to keep operating safely even as river levels rise. The plant is located 132.5 feet above mean sea level and the river is expected to crest at 95 feet on May 19. No safety-related equipment is expected to be affected by the flooding. But as a preventive measure, plant personnel are sandbagging and applying waterproof sealants to buildings and non-safety related equipment.
Emergency diesel generators have been checked and re-checked as have emergency batteries that would be relied on in the unlikely event the diesels fail. Unlike at Fukushima, the diesels are located in water-proof buildings.
Be sure to stop by to see what the other two plants are doing.
