  2. Outline • New Version Content • Updates Included Since Version 2.4.3 • Performed Testing • Number of users with beta version

  3. RELAP5-3D CHANGES SINCE VERSION 2.4.3 • RELAP5-3D Changes/New Features Since Version 2.4.3 • New Features • FORTRAN 95 • Restructuring with FOR_STRUCT • Developmental Assessment • Improved Time Step Control • Improved Nodal Kinetics • Institutionalized Card 1, Option 3 (Consistent Sound Speed Calculation between Volumes and Junctions when Noncondensables are Present)

  4. RELAP5-3D CHANGES SINCE VERSION 2.4.3 (cont.) • Allow Efficiency Multiplier (for Type-3 Turbine) using a Control Variable and Turbine Inlet Junction Form Loss Multiplier using a Control Variable • Allow PVM Coupled Restart from Uncoupled Runs • Modified PVM Coupling to send any RELAP5-3D Nodal Kinetics Variable instead of the Restricted List of Power, Zone, Heat Structure Average Temperature, etc. • Added Card 1 Option 27 to set Theta Velocity in Outermost Ring of Rigid Body Rotation and R-theta Symmetric Problems to 1.0 m/s • Added Card 1 Option 29 to allow more Accurate Solution to Momentum Equations for Low Flows • Allow Fluid Interactive Capability for the Working Fluid D2O • Allow Input Options NEW and NEWATH to use all Working Fluids

  5. RELAP5-3D CHANGES SINCE VERSION 2.4.3 (cont.) • ANS 2005 Decay Heat Standard • Pump Head and Torque Multiplier as a Function of Pressure and Void Fraction • CO2 Properties Improvement for Running near and through the Critical Point • Improved Compressor Model (Allow Input Negative Flows on Speed Tables, Allow Compressors to Run with Noncondensable Gases) • Added Command Line Argument ‘-stat’ for Run Statistics for Developmental Assessment

  6. RELAP5-3D CHANGES SINCE VERSION 2.4.3 (cont.) • 2D Heat Conduction Model without Reflood • Alternate Heat Structure – Fluid Coupling Model • Linux SUSE Platform Capability • R5FORCE Windows PC Platform Capability • PVM Coupling Junction • Fluids DOWTHERM A and R134a (SUVA) • Added Card 1 Option 71 to allow Improved Metastable Extrapolation into Superheated Liquid • Added Additional Mass Error Edits • AptPlot Capability
