Using EMRALD to Simplify and Perform Dynamic Analysis with MAAP
Event Modeling Risk Assessment using Linked Diagrams (EMRALD) is a software tool developed at Idaho National Laboratory for researching the capabilities of dynamic probabilistic risk assessment (PRA). It provides a simple interface to represent complex interactions often seen when developing dynamic models. EMRALD can also interface with other applications by modifying inputs, running, and using their results within EMRALD for dynamic and integrated assessment. Linking with external codes was formerly done by user-defined scripts, requiring users to be familiar with both the scripting and the details of the application they wanted to use. A recent, enhanced feature to EMRALD provides a library capability to add custom forms for developing simple interfaces to run specific applications, making it so the user does not need to write scripts or have extensive training in the tool they want to pull data from. This feature is especially useful for thermal hydraulic applications such as Modular Accident Analysis Program (MAAP), in which after the plant model is developed, an inhouse MAAP expert is still needed to make any modifications for an analysis. This report outlines the custom form process used to develop an EMRALD user interface for MAAP and demonstrates how it can be used to enable a typical analyst to easily perform a custom thermal hydraulic analysis with existing MAAP general model.

Bio: Steve Prescott is a software engineer at the Idaho National Laboratory. He started working on the PRA software EMRALD as an intern and has never stopped working on risk analysis software since. Now his primary focus is on dynamic PRA and incorporating other tools such as fire, flood, and physical security. For fun and to have a place to live, over the last few years, he designed and built a net zero house that is solar powered and solar heated.
