I SEQUOYAH NUCLEAR PLANT ENGINEERING RELATED EMPLOYEE CONCERNS SPECIAL PROGRAM NON-RESTART JUSTIFICATION

SUMMARY

SUBCATEGORY / ELEMENT 235.1(B)

The issues in the concerns were raised on WBN and are considered generic to SQN since the 480V receptacles are similar to both plants. However, the adequacy of 480V power receptacles has no effect on plant safety because these receptacles are used as j[

temporary power for plant maintenance equipment and are supplied from a non-lE power source. Therefore the concerns are not considered a restart issue.
