A Non-Unique Probes Selection Algorithm Using d-Disjunct Matrix

In a nuclear reactor installation, a steam generator's live-steam line leading through the containment, is equipped with a fast-acting shut-off valve, to shut off the steam in the event of a line break. If the steam pressure rises in the generator, the valve acts as a safety valve and releases a small amount of steam, so that there is no danger of damage to the steam generator. The invention is of interest particularly for light-water reactors, e.g., pressurized-water reactors.
