Safety system producing lightning-like discharges in pressure vessel of nuclear PWR reactor ignites hydrogen releases

摘要

The purpose of the invention is to maintain particularly low levels of hydrogen inside the entire inner chamber of a nuclear power station containment (1) provided with a device for igniting hydrogen contained in a hydrogen-air mixture. This is achieved according to the invention by providing a central spark-producing electrode (2) connected to a high-voltage source (4) for generating a voltage greater than the air breakdown voltage.
