in compliance with the applicable NDE procedure and applicable

Code requirements.

d. Inservice NDE results are compared with the recorded results

of prior Section XI examinations.

e. The method used for NDE was sufficient to determine the full

extent of indication or acceptance.

02.04 Obtain the records for the two most recent Code repair and

replacement activities. Verify that the following requirements are

met:

a. The method, extent, and technique of examination comply with

the licensee's Code repair/replacement procedures.
73755 - 4 - Issue Date: 01/14/86

b. The examination data are within the acceptance criteria as

outlined in the applicable Code repair/replacement procedures

and applicable Code requirements.

c. The recording, evaluating, and dispositioning of findings are

in compliance with the applicable Code repair/replacement

procedures and applicable Code requirements.

d. The method used for NDE was sufficient to determine the full

extent of indication or acceptance.

73755-03 INSPECTION GUIDANCE

General Guidance. This procedure should be run for the first ISI

of each unit. Subsequent reviews shall be conducted twice within

a three-outage cycle. One of these inspections shall be an

in-office review of the Owner's ISI Report, while the other shall

be an onsite data review. The inspection frequency at the site

should be increased if the licensee receives a Category 3 SALP

rating in the "outage" functional area. In-office review of the

Owner's ISI Report should be charged to this inspection procedure

on NRC form 766, rather than to inspection procedure 90713. MC 2515

applicability requirements for inspection items delineated in

section 73755-02 are 100% for each additional unit at duplicate

facility sites and at other multifacility sites.

The ISIs of interest in this procedure are those nondestructive

examinations of Class 1, 2, and 3 components and system leakage and

hydrostatic tests performed to meet the requirements of the TS and

the ISI program accepted by the NRC. Inservice testing of pumps and

valves as described in ASME Code Section XI is not included within

the scope of this procedure.

Examination data, test results, and other NDE data and records are

essential for comparison with future examinations to establish a

history of findings and indications. Evaluation of the previous

growth rate of flaws and other indications permits a realistic

prediction of expected further growth based on valid examination

data. Therefore, it is essential to have complete, reliable, and

clear NDE data, records, and files for each examination.

It is the intent of this inspection procedure to review examination

findings to assure that corrective measures are taken on adverse

findings, and to ensure that the licensee has used the services of

the Authorized Nuclear Inspector (ANI) and ANII, as required. If

the situation arises wherein the authorized inspector appears to

have neglected to perform his assigned activities, the matter should

be referred to IE Headquarters.

Additionally, since Section XI requires that the Owner's ISI Report

be filed with the NRC (in practice, the Regional Office), completion

of this review by the inspector at the frequency stated above will

ensure systematic and programmatic handling of these reports and

documentation of the inspector's review.

03.01 Specific Guidance.
Issue Date: 01/14/86 - 5 - 73755

a. Inspection Requirement 02.01. Pursuant to 10 CFR 50.55a(g),

the licensee periodically submits an updated ISI program to

the NRC for review and approval. Requirements delineated in

this program are regulatory requirements as are the TS. In

the event of conflict between the TS and 10 CFR 50.55a(g), the

regulatory position is that of the more stringent requirement.

As required by Section XI, the licensee prepares records of

inservice inspections. With the advent of inspection of Class

2 components and Class 3 systems, inservice inspections may

occur at different times during the calendar year. Therefore,

to determine the licensee's compliance with the extent and

frequency of required examinations and pressure tests, the

inspector performs a review of the collective records for the

current inspection period. Exceptions to or exemptions from

testing requirements shall be consistent with those permitted

by the ISI program approved by the NRC.

b. Inspection Requirement 02.02. The inspector should use the

listing of required documents as a "checklist" during the

review of the three selected sets of NDE records for completeness and technical adequacy. In addition, the inspector

should ensure that the following requirements were met for the

test records reviewed:

1. The examination unit calibration data sheets show no

major deviations between initial and final calibrations.

2. Collected examination data and any recordable indications

are properly recorded to permit accurate evaluation and

documentation.

3. Evaluation of examination data is performed by a Level II

or Level III examiner.

4. Evaluation of examination complies with the procedure.

5. Evaluation of indicators complies with the criteria of

the NDE procedure and ASME Code Section XI, if applicable.

6. Incomplete examinations and results were repeated to

permit full evaluation, if applicable.

c. Inspection Requirement 02.03. The NRC inspector shall

evaluate the data and references of these selected sets of

inspection records and verify that the licensee's inspection

program and procedures have been followed for the requirements

listed in 73755-02 of this procedure. For the review of

evaluations of examinations, the inspector should ascertain

whether the inspection procedure criteria have been followed

and whether the limitations for acceptability exceed the

limits set forth in ASME Code Section XI and the TS.
