ENCLOSURE NOTICE OF DEVIATION Duke Power Company Docket Nos. 50-269, 270, and 287 Oconee 1, 2, and 3 License Nos.

states in part that those portions of Engineered Safeguards Systems which may see recirculated reactor building sump water following a Loss of Coolant Accident are required to be Class II (Duke Class B).
Contrary to the above, the portions of the Unit 1 and Unit 3 low pressure injection systems between check valves LP-29/30 and motor operated valves LP-21/22 are classified as Class III (Duke Class C),
even though this piping may see recirculated reactor building sump water following a Loss of Coolant Accident.
This Deviation is applicable to Units 1 and 3.
B.
Final Safety Analysis Report, section 3.2.2.1, "System Classifications,"

Contrary to the above, welds between classes of systems are not performed and inspected in accordance with the rules of the higher class. The licensee program performs and inspects welds between classes of systems in accordance with the rules for the lower class.
