Release of FAVOR Code Version 20.1.12
NUMARK has supported US Nuclear Regulatory Commission (NRC) efforts to update and improve the FAVOR computer code used by NRC to evaluate issues related to the integrity of Reactor Pressure Vessels (RPVs). FAVOR is used to analyze the impact of normal and potential accident thermal-hydraulic loads on RPVs. Based on the RPV materials of construction, and how these materials degrade over time as a result of radiation, FAVOR evaluates pressurized thermal shock from plant transients and the potential impact on pressure vessel integrity resulting from stresses applied during normal plant heat-up, cooldown and pressure tests. FAVOR is also used to evaluate applications for extended nuclear plant operations and issues identified from plant inspections and measurements of the capsules removed from RPVs.
A new release of FAVOR (version 20.1.12) has been approved by NRC that adds an option to evaluate as-found or user defined flaws. A revision of the FAVOR Theory manual (Technical Letter Report TLR-RES/DE/REB-2021-03) has been issued to document the Algorithms, Methods, and Correlations used in FAVOR. A revision of the FAVOR User's Guide (TLR-RES/DE/REB-2021-04) provides information on the inputs and models used in FAVOR. In addition, NRC has published a number of FAVOR Software Quality Assurance related documents. Links to these documents are provided below.
