15. Minimum light intensity at the inspection site is prescribed.

16. The technique for evaluating indications is specified. acceptance

• standards are included. and techniques and standards are consistent /.

with applicable Code and specific contract requirements.

• 17. Reporting requirements are specified.

18. The procedure requires requalification when changes are encountered in any of the following parameters:

(a) Surface treatments that may alter the condition of surface openings (blast cleaning. acid etching).

Cb) Change in precleaning materials or methods.

Cc) Change in the type of penetrant materials (including developer. etc.) or in processing technique.

Cd) Change in surface examination temperature limits.

02. 02 Work Observation. Observe the performance of LT examination ( s) for randomly selected weld samples and conduct the following reviews:

a. Determine whether the applicable drawings. instructions. or travelers clearly specify the test procedure to be used and whether a copy of that procedure is available in the areas in which the work is being performed.

b. Determine whether the sequencing and timing of the examination relative to other operations such as grinding. welding. or heat treating are specified and are in accordance with applicable Code and contract requirements. *

c. Identify for subsequent record review the personnel performing the examination and ascertain whether they a re qualified to perform the assigned task.

d. Determine whether the required equipment and materials are at the work station. Identify the seri a 1 number ( s) of materials for subsequent record review and ascertain whether the certifications are available that demonstrate conformance with the applicable sulfur and halogen limitations.

e. Determine are clearly defined. whether the specific areas. locations. and extent of examination

f. Determine whether the following test attributes are as specified in the applicable procedure being used and whether they are consistent with the applicable Code and contract requirements:

1. Surface preparation/cleaning method. type. time. etc.

2. Penetrant type (intermixing of materials from various manufacturers is not recommended). *

3. Penetrant application method.

9. Developing time.

g. Determine that the indications are being evaluated at the proper time in accordance with the procedure requirements using the correct acceptance criteria. and are reporting the results in a prescribed manner.

h. Verify that the licensee has nondestructive examination (NOE) indication evaluation process that contains a provision for adequate corrective action or analysis of the indication before plant system startup.

i. Determine whether examined surfaces are cleaned at the conclusion of the examination.

02. 03 Record Review

57060 - 4 - Issue Date : 03/09/99 57060-03 INSPECTION GUIDANCE General Guidance

a. Review applicable portions of the Safety Analysis Report (SAR) to determine licensee commitments relative to NOE of components and

• equipment. The applicable Code editions and special requirements will generally be indicated in specifications. drawings, and/or QA manuals.

The inspector is responsible for determining the acceptance criteria for each individual application.

b. Inspection of LT examination as outlined in this procedure can be described as a three-phase. progressive review: First. a general audit is made of the applicable LT procedure to verify that it is properly prepared. approved and qualified in accordance with the applicable Code and contract requirements. Secondly. the use of the procedure is observed with the licensee's or contractor's QA program and that personnel to verify that the work is planned. scheduled. and completed in accordance performing the examination are properly qualified.

Finally records are reviewed to verify that they are complete. accurate and retrievable. It is preferable to complete all phases of the procedure during a single inspection. However. this may not always be possible since there may be no LT examination in progress during a particular inspection. Under such circumstances. completion of a specific phase of the procedure may be deferred and then resumed during a subsequent inspection.

C. Findings from this inspection activity should address each element as being satisfactory, being unresolved and requiring resolution. or being in violation and requiring correction. When significant inadequacies are

• identified indicating possible generic deficiencies. the issue should be addressed at the appropriate level of licensee management.

Specific Guidance 03.01 Procedure Review. The LT examination method described in Section III.

V. or XI of the ASME Code is applicable to most conditions encountered during fabrication and inservice inspection. However. the Code recognizes that special conditions may be encountered. which require modification of these techniques. If modified procedures are used. they must be equivalent or superior to the Code techniques. Such special procedures must also be proven by demonstration to be capable of detecting di sconti nui ti es to at least the same extent as the applicable Code technique under normal condi ti ans. This applies to all NOE procedures used to meet Code acceptance criteria.

03.02 Work Observation. The actual number and location of welds to be inspected should be. selected by the inspector. The number of welds selected for observation should be adequate to permit an effective evaluation of the inspected LT examination activities.

evaluation. or supervision of NOE should meet the requirements stated in the applicable codes and standards referenced in the licensee's SAR. Qualification certificates. visual acuity. color vision examination. and periodic recertification should be included in the licensee's or contractor's procedures.
