Safetyvessel for a nuclear installation with an ignition system for recombining Hydrogen in a gas mixture.

摘要

An ignition system has a plurality of spark igniters for the recombination of hydrogen in a gas mixture. The ignition system provides and ensures reliable early ignition of an ignitable gas mixture, even in the case of comparatively fast gas displacement. Each spark igniter is, according to the invention, configured as a high-speed igniter with an operating frequency in excess of about 10 Hz. In order to ensure reliable ignition of the ignitable gas mixture both in the event of a temporary failure of external units, and when the ignition system has a particularly long operating time, the spark igniters are advantageously connected together in groups for supplying them with energy. Each group of spark igniters is connected to an intermediate energy store common to them, and the intermediate energy stores are connected to a central energy supply unit.
