.H; Page 2 of 5 VISUAL EXAMINATION OF SUPPORT ME}GERS AND STRUCTURES FOR PIPING, VALVES, AND PUMPS BY DIRECT OR REMOTE VIEWING SwRI-NDT-900-4

1. PURPOSE This procedure provides the technical information and detailed steps required to ensure a complete and accurate visual examination of support mem-bers and structures for piping, valves, and pumps by direct or remote viewing in accordance with the applicable ASME Boiler and Pressure Vessel Code.
2. SCOPE AND APPLICATION (1) Direct and remote visual techniques for the examination of support members and structures for piping, valves, and pumps are described in this procedure.

(2) Components, parts and areas to be examined shall be as specified in the applicable SwRI Exauination Plan.

3. APPLICABLE DOCUMENTS The following documents, as applicable, form a part of this procedure:

(1) ASME Boiler and Pressure Vessel Code,Section XI,1974 Edition with Addenda through Summer 1975, " Rules for Inservice Inspection of Nuclear Power Plant Components" (2) ASSE Boiler and Pressure Vessel Code,Section V, 1974 Edition with Addenda through Summer 1975, "Nondgstructive Examination" (3) swr 1 Nuclear Quality Assurance Program Manual (NQAPM) 3.1 Applicable Examination Record SwRI-NDTR Form No.17-28, Revision 7-31-75 f 4. RESPONSIBILITY (1) The Director of the Department of Engineering Services, Quality Assurance Systems and Engineering Division, shall be responsible for l the preparation, review, approval, and control of this procedure.

(3) The examiner shall be responsible for implementing the requirements of this procedure.

(4) The Manager of the Support and Administration Section, Quality Assurance Systems and Engineering Division, shall be responsible for storage of records generated in accordance with this procedure.

5. PERSONNEL AND EOUIPMENT Personnel performing examinations shall be certified in accordance with SwRI NQAP 11-2, " Procedure for Certifying Visual Examination Personnel."

The Visual Examination Acceptability Test Card shall be made from Kodak Neutral Test Card No. R-27 or an equivalent, with an 18% neutral grey side g having a 1/32-inch wide black line across its center.

Commercially available equipment shall be used as required for the per-formance of examinations by the techniques described in Paragraphs 6.2 and 6.3.

6. EXAMINATION METHOD 6.1 Surface Cleaning Visual examinations which require clean surfaces or decontamina-tion for valid interpretation of results shall be preceded by appropriate cleaning processes.

Examinations may be required where the surface is painted or has other types of coatings. This shall be permitted if it is determined that such coatings do not interfere with valid interpretation of results.

6.2 Direct Visual Technicue Direct visual examination shall be performed by placing the eye within 24 inches of the surface to be examined and at an angle no less than 30 degrees with the surface to be examined. Mirrors may be used to improve the angle of vision, and aids such as magnifying lenses may be used.

6.2.1 Lichting In addition to the general lighting, illum1.ation of the area to l be examined shall be provided at right angles and oblique angles to expose cracks or evidence of corrosion or erosion.

/R pg f#' f;;3) Page 4 of 5 6.2.2 Resolution Resolution shall be considered adequate when the combination of access, lighting, and angles of vision, either unaided or corrected, can resolve a black line, 1/32-inch wide, on an 18% neutral grey card placed on the surface to be examined.

6.3 Remote Visual Technique Remote visual examination may be used where conditions exist that do not permit direct visual examination. Remote visual examination may include visual aids such as telescopes, periscopes, borescopes, fiber optics, or video cameras and monitoring systems, with or without attachments for permanent recording. Remote techniques shall demonstrate the ability to provide a surface resolution at least equivalent to that obtainable by direct visual examination. Mirrors, movable lights, or rotating optics, or any combination thereof, may be employed to display cracks, surface scratches, or evidence of corrosion, erosion, misalignment, or movement.

Scanning parameters, if required for the remote visual exami-nations, shall be included in the applicable SwRI Scan Plan.

6.3.1 Resolution Resolution shall be considered adequate when the combination of access, lighting, and angles of vision, either unaided or corrected, can resolve a black line, 1/32-inch wide, on an 18% neutral grey card placed on the surface to be examined or in a situation similar to the area to be visually l examined.

6.4 Reolication i

Surface replication techniques.shall be considered acceptable provided the surface resolution is at least equivalent to that obtainable by direct visual technique.

7. EXAMINATION AREAS Section XI of the ASME Boiler and Pressure Vessel Code requices visual examination to provide a report of the general condition of the part, compo-nent, or surface to be examined, including such conditions as surface scre tches, wear, cracks, corrosion or erosion on the surf aces, misalignment or movement of the part or ceaponent, or evidence of leaking.

Components, parts and areas to be examiaed shall be as specified in the applicable SwRI Examination Plan.

Weld areas to be examined shall include the weld and adjacent base material for at least one wall thickness beyond the edge of the weld.

"]:3f Page 5 of 5 The support settings of constant and variable spring-type hangers, snub-bers, and shock absorbers shall be recorded in the " Remarks" section of the SwRI Visual Examination Record.

Hangers having calibrated load indicators shall have the scale reading recorded in the " Remarks" section of the SwRI Visual Examination Record.

Hydraulic snubbers shall be examined for signs of fluid leakage at shaft seals, joints, and couplings. Shaft extensions shall be examined for scratches, cuts, or gouges.

Hanger springs shall be examined for integrity to ensure that springs have not sheared.

Pipe clamps and U-bolts shall be examined to ensure that they are securely attached to the pipe.

8. RECORDING CRITERIA Visual abnormalities shall be recorded on the SwRI Visual Examination Record and reported to the customer.

Indications shall be recorded in accordance with the techniques outlined in the applicable revision of SwRI Procedure IX-FE-ll6.

Visual indications detected during remote examinations shall be recorded in accordance with the customer specifications, remote equipment manufacturer's specifications, or the SuRI scan plan, if applicable.
