Deliberate ignition of hydrogen with glow plug ignitors is one method of mitigating the possible effects of a hydrogen burn on containment integrity in potential reactor accidents. Since these accidents may produce substantial amounts of steam, experiments have been performed to determine the hydrogen-air-steam regimes for which these ignitors would be effective. Previous work examined the effectiveness of the GM AC 7G thermal glow plug and the Tayco model 3442 ignitor with hydrogen-lean mixtures. This report presents the results of tests with the GM AC 7G glow plug ignitor: (a) in the hydrogen-rich regime; and (b) in steam-condensing atmospheres.
