A technical webinar from an integrated SIA and Verdantas team

Date and time:
September 30, 2026 | 1:00 p.m. ET | 45 minutes, including live Q&A

Testing programs for advanced reactors, including SMRs, often start with a facility or a sensor list. This webinar makes the case for starting somewhere else: with the safety claim itself. An integrated team from SIA and Verdantas walks through how to trace a safety or margin claim through test design, analysis, quality assurance, and startup evidence, so the data produced holds up to scrutiny well after the test program ends.
