Availability Notice


A series of hydrogen-burn experiments conducted for the Hydrogen-Burn Survival Program is described. The experiments, executed at Sandia National Laboratories' Fully Instrumented Test Site (FITS) facility in Albuquerque, provided data concerning the hydrogen-burn thermal environment as it relates to equipment survivability in nuclear power plants.

The test plan, instrumentation, and results are presented, along with a brief discussion of test volume (scale) considerations. Conclusions drawn from the results concern the repeatability of the tests, the suitability of thermocouples for measuring gas temperatures, and the effects of initial hydrogen concentrations and fans on the responses of calorimeters and components. The effect of initial steam concentration on temperature response cannot be determined because of preignition pressure considerations.
