The Health Physics Society (HPS) Decommissioning Section is proud to announce continuation of its webinar series with more information about the San Onofre Nuclear Generating Station (SONGS).

In August 2023, the Decommissioning Section hosted the webinar presentation "Overview of San Onofre Nuclear Generating Station Decommissioning."

On 24 April 2025, 2 pm PDT (5 pm EDT), the Decommissioning Section will continue the series with participation from San Onofre personnel Bill Barley and Emery Grohregin with the presentation "SONGS Decommissioning and Partial Site Release." See below for registration details.
