Please state whether previous inservice inspections of the RHR HXs have detected any signs of leakage or age-related degradation in the subject RHR HX welds at Oconee Nuclear Station, Units 1, 2, and 3.Response: a. VT-2 visual examinations performed on the RHR Heat Exchangers at Oconee Nuclear Station, Units 1, 2, and 3 during the 1 st, 2 nd, 3 rd, and 4 th Inservice Inspection Interval have not detected any evidence of leakage from these RHR Heat exchangers, including the welds for which relief has been requested.

b. Surface examinations performed on the nozzle Mk. "M" and "N" reinforcing pad-to-shell welds and reinforcing pad-to-nozzle welds on the RHR Heat Exchangers at Oconee Nuclear Station, Units 1, 2, and 3 during the 1 st, 2 nd 3 rd, and 4 th Inservice Inspection Interval have not detected any unacceptable indications.

c. Volumetric examinations performed on the shell-to-head flange welds and shell-to-tubesheet flange welds (adjacent to Nozzles Mk. "M" and "N") on the RHR Heat Exchangers at Oconee Nuclear Station, Units 1, 2, and 3 during the 1 st, 2 nd, 3 rd, and 4 th Inservice Inspection Interval have not detected any unacceptable indications.

These results provide additional evidence that there has been no service-induced degradation on the I.D. of the LPI Coolers in the vicinity of the Nozzle Mk. "M" and "N" nozzle-to-shell welds for which relief has been requested.

Note: Prior to implementing Code Case N-706, a limited number of C1.10 volumetric examinations were performed on these shell welds during the 4 th Inservice Inspection Interval.

These Item C1.10 examinations have since been discontinued as a result of implementing Code Case N-706 which was justified, in part, because no service induced degradation or leakage had occurred in the shell circumferential welds.d. The nozzle-to-shell welds for which relief has been requested have not received any inservice volumetric examinations.

However, the inservice volumetric examinations performed on the adjacent shell-to-head flange and shell-to-tubesheet flange welds during the 1 st, 2 nd 3 rd , and 4 th Inservice Inspection Intervals provide reasonable assurance that the service conditions within the RHR Heat Exchangers have not resulted in any age-related degradation in the nozzle-to-shell welds for which relief has been requested.

Oconee Nuclear Station Unit 3 EOC-26 Service Water Piping Inspection Program Outage Planning File No.: OS-210.24 The Service Water Piping Inspection Program (SWPIP) program outage plan for Oconee Unit 3 EOC-26 was originated and reviewed by Geary L. Armentrout (ONS-PCE) and Steve Lefler, Jr.(NGO-MMP).

This process involved a detailed review of the following program tools: " Flow regime models to determine locations most susceptible to corrosion.

• Review of stress analysis models to determine locations of high stress." Inspection locations previously inspected that are due for re-inspection.

• Current and previous Industry Issues.The inspection plan is summarized on the following page and includes the necessary information for outage planning.

There are twenty-five (25) inspection locations to be examined using Ultrasonic Testing (UT). All Work Requests written within milestone dates Note the following:

• These are 'corrosion' inspections; not 'erosion' inspections.

Therefore, grid and prep procedure SM/O/B/8530/002 as well as exam procedure NDE-946 apply.* Where possible, these inspections can be slotted during the pre-outage window, utilizing personnel mobilized to support pre-outage ISI inspections.

All revisions to the plan will require the signatures of the station SWPIP coordinator and the corporate SWPIP representative in accordance with SWPIP Program requirements.

UT Data sheets for each inspection location are also included as an attachment.
