Scaling Methodologies for Nuclear Power Systems Responses

ASME VVUQ 30.1-2024, titled “Scaling Methodologies for Nuclear Power Systems Responses,” is a standard published by the American Society of Mechanical Engineers (ASME). This document focuses on scaling analysis methodologies used to evaluate the effects of differences in phenomenological behavior between experimental facilities and real-world nuclear power systems. It includes guidelines for designing facilities and experiments that can generate data to characterize phenomena in an entire system, such as integral effects test (IET) facilities, and in specific components like the nuclear core or steam generator, referred to as separate effects test (SET) facilities​​.

The standard, approved by ANSI and published on June 28, 2024, provides critical methodologies for ensuring the accuracy and reliability of experimental data used in scaling analyses for nuclear power systems. It is essential for researchers and engineers involved in nuclear system design and safety analysis to adhere to these guidelines to ensure valid and applicable results in their work​​.
