A temperature dependent D2O density model has been developed for the 3-D hydraulics module in the near real-time plant analysis code ULTRASIM. By replacing the constant density, ULTRASIM is improved in two ways. First, all 3-D hydraulic analyses performed are more physically realistic now that the temperature dependence of the D2O density is accounted for. Secondly, simple temperature driven process water transients can now be modeled and investigated, including natural circulation tests. This report describes results in both of these areas.
