This report describes the development of boiling water reactor (BWR) components that are necessary for the structuring of a best-estimate version of TRAC-BWR. These components are: the jet pumps, the steam separators, and the steam dryers. The component models satisfy their functional specifications and are in accordance with the Transient Reactor Analysis Code (TRAC) basic equations, numerics, and constitutive relations. The jet pump is developed from the TRAC TEE component. It is structured for both the Drift Flux - 1D TRAC versions. The model was run in steady-state and transient operation covering all jet pump flow regimes. The results are in general agreement with experimental data. The steam separators and the steam dryers are structured as integral parts of the pressure vessel. The steam separator model utilizes an overall flow resistance scheme to separate the phases and achieve the correct pressure drop. The steam dryer model is simulated as a flow resistance to the steam flow, and the model is tailored to give the pressure drop within the dryer.
