Strip File Creator - ASYST/RELAP/SCDAPSIM Data Extraction Tool

Simplify Strip File Creation

Creating strip files for RELAP/SCDAPSIM and ASYST no longer has to be manual or error-prone. Strip File Creator streamlines the process by analyzing input decks and generating properly formatted strip files through an intuitive graphical interface.

Works with RELAP/SCDAPSIM and ASYST input deck files (.i)

Save Time

Reduce strip file creation time from hours to minutes with intelligent automation.

Error Prevention

Eliminate manual parameter formatting errors with auto-generated parameters.

Consistency

Ensure standardized variable extraction across your entire analysis team.

Powerful Features for Engineers

Everything you need to create professional strip files from RELAP/SCDAPSIM and ASYST input decks

Intelligent Input Deck Parsing

Reads input deck files (.i) exclusively
Automatic component detection and cataloging
Supports pipes, branches, annuli, pumps, valves, accumulators
Heat structures with full mesh information
SCDAP severe accident components (fuel rods, control rods, debris)

Comprehensive Variable Database

200+ built-in quantities organized by category
General quantities (time, mass error, system totals)
Volume quantities (pressure, temperature, void fraction)
Junction quantities (flow rates, velocities, choking)
SCDAP quantities (oxidation, hydrogen, fuel melting, debris)

Dynamic SCDAP Parameter Generation

Intelligent parameter generation system that automatically adapts to the selected variable type:

Core general quantities (automatic handling)
Component quantities with simple selection
Axial-dependent quantities (component + node)
Temperature quantities (radial, axial, component)
One-click parameter fill functionality

Real-World Applications

Reactor Safety Analysis

Load RELAP/SCDAPSIM or ASYST input decks to extract key safety parameters: core temperature profiles, system pressure and flow rates, containment response, and emergency cooling system performance.

Severe Accident Modeling

Parse RELAP/SCDAPSIM or ASYST input decks to analyze damage progression: cladding oxidation, hydrogen generation rates, fuel melting and relocation, debris bed formation, and lower plenum thermal response.

Design Optimization

Track component performance across parametric studies: pump and valve operating points, heat exchanger effectiveness, system thermal efficiency, and flow distribution analysis.

Post-Processing Automation

Create standardized strip files for automated report generation, time series plotting, comparative analysis across multiple runs, and uncertainty quantification studies.
