1. A safety vessel of a nuclear facility, comprising: a safety vessel body having an interior formed therein;  an ignition system for a recombination of hydrogen in a gas mixture disposed in said interior of said safety vessel body, said ignition system having a plurality of spark igniters being a high-speed igniter with an operating frequency in excess of about 10 Hz;  a central power supply unit; and  a plurality of intermediate energy stores connected to said central power supply unit;  said plurality of spark igniters connected together in groups of spark igniters, each of said groups of spark igniters connected to one of said plurality of intermediate energy stores for supplying energy to said groups of spark igniters. 2. The safety vessel according to  claim 1 , wherein said plurality of spark igniters are low-energy igniters with an operating power of less than 10 W. claim 1 3. The safety vessel according to  claim 1 , wherein said plurality of spark igniters are low-energy igniters with an operating power of less than 5 W. claim 1 4. The safety vessel according to  claim 1 , wherein each of said plurality of intermediate energy stores has an automatic trigger with a catalytically coated temperature sensor. claim 1 5. The safety vessel according to  claim 1 , wherein each of said plurality of intermediate energy stores has an automatic trigger with an integral pressure switch. claim 1 6. The safety vessel according to  claim 1 , wherein each of said plurality of intermediate energy stores has a cooling unit. claim 1 7. The safety vessel according to  claim 1 , wherein each of said plurality of spark igniters has ignition electronics and an internal housing for providing radiation protection for said ignition electronics. claim 1 8. The safety vessel according to  claim 1 , wherein each of said plurality of spark igniter s has a housing with an insulating casing. claim 1 9. The safety vessel according to  claim 1 , wherein each of said plurality of spark igniters has an integral heat sink. claim 1 10. The safety vessel according to  claim 1 , wherein each of said plurality of spark igniters has a discharge line for conducting a coolant and a safety valve disposed in said discharge line for closing off said discharge line. claim 1
