Method for preventing dangerous hydrogen accumulation in nuclear reactor containments

摘要

In a method for the controlled removal of hydrogen released into the chambers of a nuclear reactor containment after a break of the primary cooling system, the hydrogen is contacted with an oxygen providing material stored in the containment which causes recombination of the hydrogen to H2O in a controlled manner at least until the amount of the gas within the hydrogen chamber is below the ignition limit of a hydrogen oxygen gas mixture.
