Ladies and Gentlemen On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued Order EA-12-051,."Order to Modify Licenses With Regard To Reliable Spent Fuel Pool Instrumentation" (Reference 1). This Order was effective immediately and directed holders of operating reactor licenses to install reliable spent fuel pool instrumentation as outlined in Attachment 2 of the Order. This letter, along with its enclosures, provides the notification required by Section IV.C.3 of the Order that compliance with the requirements described in Attachment 2 of the Order has been achieved for Oconee Nuclear Station (ONS), Units I and 2.(Note: The Order required that Unit 2 compliance be completed prior to restart from the refueling outage for end-of-cycle 27 (EOC2 7). However, since ONS has a common pool for Units I and 2, both units were implemented concurrently.)

On November 11, 2015, Unit 2 commenced start-up from the E0C27 refueling outage, which established the EA-12-051 Order compliance date for Units 1 and 2.

ONS-201 6-003 January 20, 2016 Page 2 Attachment 1 provides a brief summary of the key elements associated with compliance to Order EA-12-051 for ONS Units 1 and 2. Open and pending items from the NRC Audit Report (Reference

3) are provided in Attachment 2 with a summary response for each item to support closure. As such, Duke Energy considers these items complete, pending NRC closure.This letter contains no new or revised Regulatory Commitments.

Should you have any questions regarding this submittal, please contact David Haile with Oconee Regulatory Affairs, at (864) 873-4742.I declare under penalty of perjury that the foregoing is true and correct.

This Order was effective immediately and directed holders of operating reactor licenses to install reliable spent fuel pool instrumentation as outlined in Attachment 2 of the Order. For Oconee, the Order requires Unit 2 compliance prior to plant startup from the end-of-cycle 27 (EOC27)outage. On November 11, 2015, Unit 2 commenced start-up from the E0C27 refueling outage, which established the Order Compliance date for Unit 2. However, since ONS has a common pool for Units 1 and 2, both units were implemented concurrently.

The information provided herein demonstrates compliance for Oconee Nuclear Station, Units I and 2 related to the Order.COMPLIANCE

SUMMARY

FOR UNITS 1 AND 2 NRC RAI, ISE, and Audit Items -Complete All Requests for Additional Information, ISE Open Items and Confirmatory Items, and Audit Questions/Open Items have been addressed and are considered complete pending NRC closure.Identification of Levels of Required Monitoring

-Complete The three required level indications for monitoring SEP level have been established in compliance with Order EA-12-051 for ONS, Units 1 and 2. These levels are integrated into the site processes for monitoring SFP during Beyond Design Basis events, including response to loss of SEP inventory.

Instrument Design Features -Complete The modifications to install the Spent Fuel Pool Level Instrumentation have been fully implemented on ONS Units 1 and 2 in accordance with the station design control process. The design complies with the requirements specified in the order and as described in NEI 12-02, Revision 1, "Industry Guidance for Compliance with NRC Order EA-1 2-051" (Reference Al10).The instruments are arranged to provide reasonable protection against missiles.

The instruments are mounted to retain design configuration during and following the maximum expected ground motion. The instruments are designed to be reliable at expected environmental and radiological conditions including extended periods when the SEP is at saturation.

The instruments are independent of each other and have separate and diverse power supplies.

The instruments are designed to maintain their designed accuracy following a power interruption and to allow routine testing and calibration.

The instrument display is readily accessible during postulated events and allows level information to be promptly available to decision makers.Program Features -Complete Operating and maintenance procedures for the Spent Fuel Pool Instruments for ONS Units 1 and 2 have been developed, and integrated with existing procedures.

These procedures have been verified and are available for use in accordance with the site procedure control program.Site processes have been established to ensure the Spent Fuel Pool Instruments are maintained at their design accuracy.Training for ONS, Units 1 and 2 has been completed using the ONS Systematic Approach to Training (SAT) as recommended in NEI 12-02, Revision 1, Section 4.1.ONS-201 6-003 Page 1 of 2 ATTACHMENT 1 Oconee Nuclear Station, Units 1 and 2 Summary of Compliance Elements for Order EA-12-051 REFERENCES Al.
