REFERENCE:

Letter dated May 9, 1985 from Mr. S. R. Zimmerman (CPRL) to Mr. Harold R. Denton (NRC).

Dear Mr. Denton:

Carolina Power ttt Light Company (CPRL) hereby submits additional information concerning the Shearon Harris Nuclear Power Plant (SHNPP) Preservice Inspection Program (SER Confirmatory Item No. 30). Revision 2 to the Preservice Inspection Program Plan (Procedure ISI-201) is provided as Attachment 1. The categorization of Request for Relief is provided as Attachment 2.

Revision 2 to the Preservice Inspection Program Plan is provided in response to CPdcL's commitment in the reference letter to perform a volumetric exam of line numbers 2CT8-10 and 2CT8-15. This change and other changes are noted by a sidebar in the right-hand margin.

The categorization of Request for Relief is provided in response to CPRL's commitment in Section 0.0 of the Preservice Inspection Program Plan to provide this information six months prior to fuel load. The Preservice Inspection Program is in progress on piping, vessels, bolting and component supports. This submittal covers known categories where relief is required. Additional categories may be necessary as CPRL completes the Preservice Inspection Program. The specific components that fall into the categories for Request for Relief will be submitted at least three months prior'to fuel load to close the SER conf irma tory t tern.

If you have any questions please contact Mr. Gregg A. Sinders at (919) 836-8168.

Yours very truly,

CODE RE UIREME TS:

ASME section XI, Table IWB-2500-1 requires surface and/or volumetric examinations to be performed as applicable on pressure retaining welds.

RELIEF RE VESTED:

Relief's requested from examinations on Class 1 pressure retaining welds due to structural interferences such as: permanent hangers, saddle plates, support structures, or intervening members for other systems.

ALTER ATE EXA INATIO S:

To the maximum extent possible volumetric examinations were performed. Where the weld was identif'ied as being inaccessible to the volumetric examination, surface examinations were used in I ieu of the volumetric examinations. Visual examinations (VT-1) were performed on components which required surface examination, when accessible. Where access precluded or limited the examination, that fact was documented on the Preservice Base l ine Data Sheet.

( PRESERVICE/INSERVICE APPLICABLE)

CODE RE UIREME TI ASME Section XI, Table IWB-2500-1 requires volumetric and surface examinations on Z 4" nominal pipe size circumferential and longitudinal pressure retaining welds, including branch connections.

RELIEF RE VESTED:

ASME section XI requires essentially 100$ of the weld length be volumetrica I ly examined. Due to piping weld configurat ions

( reducer to tee, pipe to tee, pipe to flange etc.) volumetric examinations of 100$ of the weld length was sometimes not f'easible.

Relief is requested based on weld configurations not being conducive to 100$ volumetric examination (see additional details on Attachment "A" to this relief request).

ALTERNATE EXAMI ATIO Pressure retaining welds were surface examined for essentially 100$ of the weld length where possible. Volumetric examinations were performed to the maximum extent possible based on physical limitations. Where the component configuration or access precluded or limited this examination, that fact and to the extent was documented on the Preservice Baseline Data Sheet.

Attachment A Page 1 of 2 RELIEF REQUEST NO: Rl-003 EXAMINATIONS Ultrasonic examinations were conducted to inspect as much of the examination zone as was practical, within geometric, metallurgical, and physical limitations. When the required ultrasonic examination volume or area could not be examined 100 percent, the examination was considered to be partial and was so noted on the applicable component Data Sheet. Generally, partial examinations were done at fitting to fitting assemblies (explained under limitations) and in areas where integrally welded supports, lugs, etc.,

preclude access to some part of the examination area.

Ultrasonic examinations that produced indications 50 percent of DAC or greater from geometric or metallurgical origin were recorded. Examples of areas that,

'generally produced such indications are .as follows:

1. Inside diameter weld preparation or root configuration and the outside diameter down overlay or toe.

2. The inside diameter radius of the tube sheet weld of'he steam generators where examined from the tube sheet side.

3. The metallurgical structure of austenitic materials.

4. Signal responses from the thread areas of bolting.

LIMITATIONS Some of the arrangements and details of the piping system and components were designed and fabricated before the access and examinations requirements of Section XI of the 1980 Code could be applied; consequently, some examinations are 'limited or not practical due to geometric configuration or accessibility.

Generally these limitations exist at all fitting-to-fitting joints such as elbow to tee, elbow to valve, reducer to valve, etc., where geometry and sometimes surface condition preclude ultrasonic coupling or access for the required scan length.

The limitations exist to a lesser degree at pipe to fitting assemblies, particularly where the weld is not ground flush with the pipe O.D. surface.

At these joints examinations can be conduced form the pipe side; however, the fitting again limits or precludes examination from the opposite side.

In most cases, examinations in limited areas were accomplished as a best effort attempt to cover as much of the code required area or volume (generally, the weld and base metal for 1 "T" on each side) as possible.

However, the extent of examination coverage in the base metal of the fitting or component cannot be specifically quantified as being 100 percent. These areas where complete examination of 100 percent of the required volume of area could not be achieved were indicated and noted to the extent on the limiting cause noted.

examiners'ata Sheet and the Attachment 2 to NLS-85-327 Page 4 of 15

Attachment A Page 2 of 2 RELIEF REQUEST NO: Rl"003 LI>jITATIONS The principal basis for partial examinations is to identify the inability to examine 100 percent of the required base metal volume for the 1 T distance beyond the edge of the weld on a fitting or component. Examples are (1) ultrasonic examination of a pipe to elbow assembly, where scanning on the intrados of the elbow causes de-coupling of the sound beam and (2) a pipe to flange or valve assembly where scanning the entire volume on the fitting or component side is limited by configuration. The resulting coverage is such that examination of the weld, heat affected zone and base metal for 1 "T" on the pipe side can be achieved by scanning from the pipe side of the weld. An indeterminate coverage of the base metal on the fitting or component side may be achieved during this pipe side scan depending on the calibrated sweep length, attenuation, joint configuration, etc. However, the volume on the fitting or component side additionally cannot be scanned completely for transverse indications as required by Code. In either case, 100 percent of this 1 "T".volume cannot be assured, thus a partial examination is required as a disclaimer to having satisfied code requirements, albeit the intent is.

Specific limitations and restrictions for all examinations are as indicated on the specific report Data Sheets.
