An investigation of the effect of pressure decay rates of the order of 5 to 10 psig/sec on pool boiling burnout in water was carried out. The initial system condition was saturation temperature at pressures of up to 62.5 psig. The pressure was allowed to decay to one atmosphere absoiute at constant heat flux and the time to burnout of a stainless steel ribbon undergoing internal heat generation with surface heat fluxes of up to 5 x 10/sup 5/ Btu/hr ft/sup 2/ was measured. The resuits were correlated on the basis of the steady state curve of pressure vs burnout heat flux, which had also been determined for the system. It was found that a conservative prediction of time to burnout could be made by calculating the time from initial pressure reiease to the pressure at which steady state burnout would probably occur for the given initial heat flux. With few exceptions actual burnout occurred at longer times than this method would predict. Data obtained for various pressure decay rates, different initial pressures, and different internal generation rates are presented, and the effect of these parameters on the time to burnout and the relative data scatter is discussed.
