A system and method for predicting acoustic loads expected on a boiling water reactor (BWR) may include a BWR scale model, a test fixture for generating air flow in the scale model, and one or measurement devices for monitoring system behavior to predict how acoustic loads may affect plant operation for the BWR being evaluated.

A method of predicting stresses on a BWR steam dryer that includes creating an analytical acoustic model of a BWR steam system; generating pressure estimations by inputting empirical data into the analytical acoustic model of the BWR steam system; creating an analytical structural model of the BWR steam dryer; and predicting stresses on the BWR steam dryer using the analytical structural model and the pressure estimations.

A risk-informed method for safety analyses of nuclear power generating systems is provided. In an exemplary embodiment, the method includes ordering events by an initiating event frequency, defining an initiating event frequency threshold value, defining acceptance criteria having an adjusted amount of conservatism, where the amount of conservatism is a function of the initiating event frequency, and analyzing an event by a deterministic safety analysis methodology when the event has an event initiating frequency at or above the threshold value, or analyzing an event by a probabilistic risk assessment methodology when the event has an event initiating frequency below the threshold value.
