[en] This report supplements the technical evaluation documented in a separate report dated December 16, 1981 (UCID-19118) on the adequacy of station electric distribution system voltages for the Arkansas Nuclear One, Unit 1. The evaluation is to determine the adequacy of the tests conducted to verify the accuracy of the assumptions and system models used in the distribution system voltage analyses. The verification tests resulted in small percentage error differences which demonstrates the accuracy of the assumptions and system models used in the analytical voltage profiles
