摘要

The deliberate ignition systems installed in ice condenser PWR and Mark III BWR nuclear plants offer considerable promise for the control of hydrogen resulting from a postulated core uncovery accident. However, a second safety-related system, namely, water sprays intended primarily to reduce steam over-pressure in a similar accident, might interfere with the proper operation of the numerous resistively heated igniters used in the deliberate ignition system. Sandia National Laboratories has been requested to investigate independently how these igniters might behave during the operation of the water spray system in the containment of a nuclear plant. A series of experiments have been run with both resistively heated helical (Tayco Model No. 193-3442-4) and cylindrical (General Motors AC 7G diesel glow plug) igniters. Tests were performed with and without spray shields at various spray fluxes and with and without premixed 6 percent hydrogen/air atmospheres surrounding the igniters. (The spray shields are metal sheets mounted horizontally above the igniters.). (ERA citation 10:006880)
