INSPECTION PROCEDURE 73052

INSERVICE INSPECTION - REVIEW OF PROCEDURES

PROGRAM APPLICABILITY: 2512, 2515 (BASIC)

73052-01 INSPECTION OBJECTIVE Ascertain whether the licensee's procedures per taining to the Preservice Inspection (PSI) and/or Inservice Inspection (ISI) adequately cover all required aspects of the approved ISI program.

73052-02 INSPECTION REQUIREMENTS 02.01 Program Requirements. Review the licensee's commitments in the SAR, Technical Specifications (TS), and approved ISI program.

Ascertain that ISI procedures adequately cover all areas specified in the licensee's commitments for ISI and PSI requirements, where applicable.

02.02 Procedure Approval. Ascertain whether the ISI procedures have been approved by authorized licensee personnel and by the Authorized Nuclear Inservice Inspector (ANII).

02.03 Non-Destructive Examination (NDE) Procedure Review. The inspector should choose a sampling of procedures from each type of NDE, as appropriate, and review them for the following:

a. Scope.
1. Requirements are specified and agree with licensee'scommitments in 02.01 above, including specified or referenced acceptance levels.
2. Qualifications of NDE personnel are specified and inaccordance with the licensee's approved ISI program.
3. Methods of recording, evaluating, and dispositi oningfindings are established and reporting requirements are in compliance with applicable Code requirements. Records identified for retention should include:

(a) Examination results and data sheets

Issue Date: 01/14/86 73052 (b) Film and tape records, as applicable

73052 Issue Date: 01/14/86 (c) Examination equipment data, including records of consumable materials such as penetrant materials, ultrasonic test (UT) couplants, etc.

(d) Calibration data sheets (e) Calibration blocks, sheets, and tubes

4. If the licensee is using contractor personnel for all orpart of the ISI effort, the procedures delineate the scope of work and division of responsibilities between the licensee and the contractor.
b. Technical Content.
1. Method of examination, extent, and technique is ade-quately described and in conformance with the require-ments and guidance of ASME Code Section V.
2. Procedures include any special requirements imposed byjoint NRC or industry initiatives, if applicable.
3. Methods to record and evaluate test results are speci-fied.

02.04 Code Repair or Replacement Procedure Review. The inspector should choose one Code repair and one Code replacement procedure and review them to ensure that the elements of the procedures are consistent with the applicable requirements of the ASME Code and the approved ISI program.

a. Code Repair Procedure. Elements of a complete repair cycle that the licensee's procedure should include are:
1. Identification of the NDE method that revealed the flawand the description of the flaw.
2. Description of the flaw removal method.
3. Procedure for weld and postweld heat treatment, ifapplicable, including review of procedures for welding prior to authorization of the repair and review of qualifications of welders performing the repair.
4. Provisions for using the services of an AuthorizedInspection Agency when making a weld repair, as well as for having the ANI review and approve the repair proce-dure before its performance.
5. Description of the NDE program to be used after therepair is completed.
6. Delineation of the scope of work and division of respon-sibilities between the licensee and contractor, if a contractor is used.

Issue Date: 01/14/86 73052

b. Code Replacement Procedure. Elements of a replacement program that the licensee's procedure should include are:
1. Provisions to verify that the replacements met therequirements of the edition of the Construction Code to which the original component/part was constructed, the provisions of later editions of that same Code, or Section III of the ASME Code.
2. Provisions to ensure that the replacements ordered asspares met the requirements of the appropriate Construc-tion Code used for the part/component it was intended to replace, the provisions of later editions of that Code, or Section III of the ASME Code.
3. Justification, consistent with NRC guidelines, for notrequiring a Code stamp.
4. Evaluation of the suitability of the replacement prior toauthorizing its installation.
5. Retention of reports and records as required by theConstruction Code and ASME Code Section XI.
6. Performance of a PSI prior to the return to service ofthe replacement component or part in accordance with the applicable Code.

73052-03 INSPECTION GUIDANCE General Guidance. Review of the licensee's proced ures is to be conducted for the PSI of each unit and for the first ISI of each unit. Subsequent reviews shall be conducted each outage and should key only on revisions and newly implemented procedures.

This procedure covers ASME Section XI with the exception of those items in the PSI program that are covered in the Preoperational Test Program, Chapter 7000 of the IE Manual.

ASME Section V, "Nondestructive Examination, Subsection A -

Nondestructive Methods of Examination," sho uld be used as supplemen-tal guidance during the conduct of this inspection procedure.

However, the field of NDE is developing rapidly, causing NRC requirements, tailored to individual plants, to differ significantly from Section V of the ASME Code. In such cases, NRC requirements govern.

03.01 Specific Guidance.

a. Inspection Requirement 02.01. The ISI program and program have submitted an ISI plan to the NRC for review against therequirements differ for each facility. Each facility will requirements of 10 CFR 50.55a(g). Often, relief will have been granted from certain requirements. Therefore, the ISI program requirements must be inspected against the TS and

73052 Issue Date: 01/14/86 commitments made by the specific facility in its NRC-reviewed ISI program.

b. Inspection Requirement 02.02. According to ASME Code Section XI, it is the duty of t he ANII to verify that the NDE are performed in accordance with written approved procedures by qualified personnel. This includes verifying the technical content and requirements of examination procedures and the procedures used to qualify NDE personnel.
c. Inspection Requirement 02.03. At least one procedure from each type of NDE should be examined for technical adequacy.

The inspector should be aware of NRC initiatives in the areas of procedure and personnel certification such as the NRC/EPRI/BWR Owners Group qualification requirements for intergranular stress corrosion cracking UT inspections. The following should be used for the review of each NDE procedure selected:

1. Visual Examination. Use procedure review requirements from inspection procedure (IP) 57050 as a checklist for this review.
2. Liquid Penetrant Examination. Use procedure review requirements from IP 57060 as a checklist for this review.
3. Magnetic Particle Examination. Use procedure review requirements from IP 57070 as a checklist for this review.
4. Ultrasonic Examination. Use procedure review requirements from IP 57080 as a checklist for this review, supplemented by any special requirements imposed by NRC/industry initiatives (i.e., Regulatory Guide (RG) 1.150).
5. Radiographic Examination. Use procedure review requirements from IP 57090 as a checklist for this review.
6. Eddy Current Examination. Review the licensee's procedure to ensure that the:

(a) Multi-channel examination unit is specified.

(b) Method of examination is described.

(c) Method of calibration and sequence of calibration isdescribed.

(d) Requirements of TS or ASME Code Section XI (whicheveris applicable) have been addressed.

(e) Procedures meet the requirements and intent of RG1.83.

Issue Date: 01/14/86 73052 (f) Licensee has written approval for use of Code cases such as "N-401".

Because the specific NDE technical requirements vary among Code editions and addenda, the inspector should ensure, when using the 57050 series IPs as technical requirements checklists, that the requirements reflect those specified in the Code of record committed to by the licensee being inspected.

d. Inspection Requirement 02.04. If the inspector finds it necessary to conduct a more detailed inspection of the activity (i.e., welding, NDE), the 55050 and 57050 series IPstechnical aspects of the process procedures used in the repair should be used. The inspector, however, should ensure that only the welding and NDE requirements of the Code section used in the repair (normally Section XI with referenced portions of Section III) are applied to the inspection of the process procedures. Additionally, the inspector should ensure that the licensee has evaluated all repair and replacement actions in accordance with 10 CFR 50.59 to ensure that there are no unresolved safety questions.
