When steam turbines trip the turbine stop valve closes rapidly which generates a steam hammer transient wave. This wave can cause significant transient loads on piping. The de facto method of predicting these loads is the Goodling Method from the 1980s. AFT’s newest software product AFT xStream revealed that the Goodling Method was not always conservative – which means that existing fossil and nuclear power stations are not as safe as believed. Using this information, an improved analytic method has been developed and will be discussed.
