Title	Part 21 - Deviation to Qualified Design
Event Description	The following information was provided by United Controls International via email: Schneider Electric part number: ASP840-000 Modicon Primary/Secondary Power Supply units failed to operate several days after installation at Dominion's Surry Power Station with hard failures that shutdown the associated programable logic controller. The units were returned to UCI and initial observations indicated heavy shipping damage that was not present when initially supplied. Further evaluation of the damaged components requires manufacturer evaluation due to item complexity and proprietary design documentation. Investigation into the root cause(s) of the failures is ongoing. Evaluation of whether these failures represent deviations or failures to comply that would be associated with substantial safety hazards will be complete by July 2, 2023. For questions concerning this potential 10 CFR 21 issue, please contact: Anu Kulkarni Quality Assurance Manager United Controls International (470) 610-0851
