Checking North Anna, Free Lance-Star, August 31, 2011:
Is North Anna safe?
[...] Now the question is, did the quake damage the nuclear reactors, underground piping, or critical electrical equipment? What’s more, did the temblor’s intensity exceed North Anna’s design?
It’s not possible, with a multi-ton reactor, to simply crawl under the hood to check for damage. [...]
After Fukushima, but before the recent East Coast quake, the NRC began a review of U.S. nuclear plants and found a few “discrepancies” at North Anna including:
- Portions of the water and gaseous suppression systems and hose stations are not seismically designed.
- A fire-pump storage area is non-seismic.
- Seismically designed floodwalls are located in the non-seismic turbine building.
