Nuclear Plant Containment Failure: Pre-Existing Damage

, former director, Nuclear Safety Project

Disaster by Design/Safety by Intent #31

Disaster by Design

Federal regulations require that nuclear plant containments withstand the temperature, pressure, hydrodynamic forces, humidity, and other consequences from design basis accidents and limit the amount of radioactivity to the atmosphere. By limiting the radioactivity release, containments minimize the harm to nearby populations and the environment.

The surest way for a containment to be damaged after an accident and be unable to fulfill this safety function is for it to be damaged before the accident starts. Read more >

Disaster by Design/Safety by Intent #3

Disaster by Design

The primary purpose of commercial nuclear power plants in the U.S. is to generate electricity. When not fulfilling that role, nuclear power plants that are shut down require electricity to run the equipment needed to prevent the irradiated fuel in the reactor core and spent fuel pool from damage by overheating. The March 2011 accident at Fukushima Daiichi in Japan graphically illustrated what can happen when nuclear plants do not get the electricity they require. Read more >
