ABSTRACT Oak Ridge National Laboratory (ORNL) has been engaged by the U.S. Nuclear Regulatory Commission (NRC) Office of Nuclear Regulatory Research (RES) to develop the technical basis for regulatory guidance to address design and implementation practices for lightning protection systems in nuclear power plants (NPPs). With the advent of digital and low-voltage analog systems in NPPs, lightning protection is becoming increasingly important. These systems have the potential to be more vulnerable than older, analog systems to the resulting power surges and electromagnetic interference (EMI) when lightning hits facilities or power lines. This report documents the technical basis for guidance on the protection of nuclear power structures and systems from direct lightning strikes and the resulting secondary effects. Four Institute of Electrical and Electronics Engineers (IEEE) standards are recommended for …
