Fundamental to the successful operation of any nuclear site is a first-class safety culture which strives to continually improve in response to good industry practices and operating experience feedback. Speakers will provide examples of either lessons learnt and / or specific good practices at their site, following which an audience discussion will be initiated on alternative good practices and experiences in these areas. Confirmed panellists are: - Brittany Williamson (SRS), presenting on "Near Miss Criticality Accident in FB-Line in 1984 - Lessons Learned for SRPPF Today" - Kristan Wessels (Amentum), presenting on "A Review of Heath Impacts from Criticality Accidents" - Greyson Mondini (Y-12), presenting on "Lessons Learned in Start-Ups of New Fissile Processes"
