.,i A summary of the indications is as follows:

Fro~_all inspections performed for the preservice examination of Unit one no Q1dications were found to be recordable.

Examinations Examinations were conducted to review as much of the examination zone as was practical, within geometric, metallurgical and physical limitations. When the required examination volume or area could not be examined 100%, the examination was considered to be partial (PAR) and so noted. Generally, PAR's are noted at fitting-to-fitting assemblies (as explained under LIMITATIONS) and in areas where integrally welded supports, lugs, hangers, etc., preclude accesi to some part of the examination area.

Ultrasonic examinations that produced greater than reference level sensitivity from reflectors that are characteristic of metallurgical structure of the I.D./0.D. surfaces of an item were acknowledged for information only and were noted as such on that data sheets. Examples of areas that generally produce such geometric indications include:

(1) I.D. weld prep or root and or the crown overlay or toe.

(2) The I.D. radius of the tube sheet on the channel head to tube sheet weld of steam generators, when examining from the tubesheet side.

(3) The metallurgical structure of cast materials.

(4) Responses from the thread areas of bo 1t i_ng.

Geometric responses from these areas are charateristic*of the examination and are not considered relevant for reporting le_ngth or depth.

Limitations Some of the arrangements and details of the p1p1ng system and components were designed and fabricated before the access and examination requirements of Section XI of the 1974 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

.e1bow to tee,. elbow to valve,-reducer to valve, etc. where geometry and some-tim~ surface condition preclude ultrasonic coupling or access for the required scan:length.

The limitations exist to a lesser degree at pipe fitting assemblies, particularly where the weld is not ground flush with the pipe O.D. surface. At these joints examinations can be conducted from the pipe side, however, the fitting again limits or pr~cludes examination from the opposite side. When the weld surface is flat, the fitting side examination is replaced by a calibrated straight beam examination on the weld.

In most cases, examinations in these 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 11 T11 on each side) as is possible, however, the extent of examination coverage in the base metal of the fitting or component cannot be spe~ifically qualified. _

,;~-

""Areas where complete examination of 100% of the required .volume or~*area could not*:be achieved are indicated by a PAR (partial) notation on the examiner's dat-~- sheet, and the 1 imiting cause is noted.

The principal basis for PAR 1 s is to identify the inability to examine 100%

of the required base metal volume for the 1 11T11 distance beyond the edge of the weld on a fitting or component, such as: ultrasonic examination of*

a pipe to elbow assembly, where scanning on the intrados of the elbow causes de-coupling of the sound beam; or a pipe to flange or valve assembly, where scanning the entire volume on the fitting or component side is limited by con f i gu ration.

The resultJng coverage is such that examination of the weld, heat affected zone and base metal for 1 11 T11 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% of this 1 11 T11 volume cannot be assured, thus a PAR is required as a disclaimer to having satisfied code requirements, albeit the intent is satisfied to the extent practical.

Specific limitations and restrictions for all examinations are as indicated on the raw data sheets .
