Thousands of cracks in Belgian reactors, potentially a global nuclear problem
Thousands of cracks have been discovered in the pressure vessels of both reactors. This component is required to be integrally sound, with no risk of failure, due to the potentially catastrophic nuclear disaster resulting from the failure of a pressure vessel.
As reactors age, the steel of the reactor pressure vessel is damaged – or embrittled – by radiation. According to the scientists, hydrogen from the water in the pressure vessel – which cools the nuclear fuel core – may be corroding the steel by injecting hydrogen atoms into the steel of the vessel itself, where it can accumulate and build up pressure, resulting in the steel blistering – effectively breaking up the pressure vessel from within.
