On October 28^th, the Structural Integrity (SI) Nuclear Fuel Technology Team achieved a major milestone in completing the first Verification & Validation phase in the development of its nuclear fuel performance and behavior code Pegasus^©.  “This is a significant step by the SI Team” commented Vick Nazareth, SI Fuel Director.  “We have been developing Pegasus^© since 2017 to incorporate cutting edge computational technology and four decades of fuel behavior modeling and analysis expertise into a software program”.  The code addresses a need for deeper fuel integrity insights within the nuclear industry to achieve next level fuel performance and licensing.  Dr. Joe Rashid, Scientist and Senior Technology Developer of the code added “this code will analyze fuel behavior through the entire fuel cycle from initial startup to used-fuel storage”.

SI announced the development of Pegasus^© in the SI newsletter in 2019, Introducing Pegasus: State-of-the-Art Nuclear Fuel Behavior with the objective of enhancing the fidelity of fuel behavior and performance in support of advanced fuel technologies.  The Pegasus^© code will go through additional validation testing over the next several months to meet a production roll-out in early 2021 in support of fuel performance behavior analysis across a broad spectrum of light water reactor and advanced reactor fuel designs.

” I am proud of the SI Fuel Team”, said Mark Marano, SI CEO.” This milestone exemplifies our ability to provide innovative structural integrity solutions for clients across structures, systems, components, water chemistry and nuclear fuel.”
