SUMMARY OF FINDINGS

%)i

s

l'

Enforcement Action

1.

Inservice inspections of pressure boundary welds was performed

using a procedure which specifically stated it is not applicable

for inservice inspection. Contrary to this the licensee approved

subject procedure on April 18, 1974. This is a violation of Criterion

X, Appendix B, 10 CFR 50.

(Details, Paragraph 3)

2.

Inservice inspection of vessel support skirt weld was performed

using a calibration block which is not in accordance with the -

require.ments of Section III of the ASME Code.

Other Significant Findings

A.

Current Findings

(1) Review of the qualification records for NDE technicians performing

inservice inspection reveal no apparent deficiencies.

(Details,

Paragraph 2)

(2) Equipment calibration and mill certificates for penetrant

materials used in the inservice inspection program revealed no

apparent discrepancies.

(Details, Paragraph 5)

(3) Eddy Current inspection of poison control blades identified

sheathes which contain inverted tubes.

(Details, Paragraph 6)

(4) The inspectors review of the repair program for the moisture

separator revealed no discrepancies.

(Details, Paragraph 7)

Qualifications of Test Personnel

i

The inspector reviewed t'se qualifications, abilities and levels of

the licensee's inspection agency performing inservice inspection.

!

It was pointed out by the inspector certain test personnel were not

certified as being qualified.- The Level III Examiner for the

.

licensee's inspection agency stated the' personnel were qualified

  1. se1

and certified their qualification on each applicants record by

affixing his name and his title (Level III Examiner). This item is

considered resolved.

3.

Procedures and Instructions

The inspector reviewed the licensee's inspection agencies pro-

cedures, applicable for inservice inspection.

Procedure 13N Ultrasonic

Proc / Nuclear Welds, Paragraph 13.2.2 states; "---This procedure is

,

L

not applicable and shall not be used for in-service inspection-- ."

Contrary to this the inspector noted procedure 13N is referenced as

the procedure used for inspecting welds. The licensee's inspection

agency stated 13N is applicable and proper to use while performing

,

'

inservice inspection and paragraph 13.2.2 of 13N is in error. It

was noted the licensee approved procedure 13N on April 18 - 1974 f or

use en inservice = inspections. This is an apparent violation of

Appendix B, .10 CFR 50,- Criterion IX.

Inservice Inspection Techniques

The inspector. reviewed the preliminary data which was obtained from

the inservice inspection performed during the present outage'. The

'

inspector noted the vessel support skirt was ultrasonically, inspected

using a reference calibration block which could not be demonstrated

as providing equivalent response to the basic calibration block

required by ASME Code Sec. III, Paragraph 1X-343(b) . ASME Sec. III

.

.

Paragraph II-343 states in part, "---Drilled holes shall be used as

e

basic calibration reflectors to establish a primacy reference

response of the equipment. ...These holes shall be located either in

the production material or in a basic calibration block of an

equivalent P-Number-- ." The calibration block used for the inspec-

tion was not in accordance with the above requirements. Allowances

are made in paragraph IX-343(e) of Sec. III of the ASME Code which

states;

"---In lieu of the above, other calibration reflectors are

permitted, provided equivalent response is demonstrated-- ."

Failure of the licensee to perform equivalent sensitivity comparison

is a violation of Section III of the ASME Code.

5.

Equipment Calibration and Mill Certificates of Penetrant Materials

The inspector reviewed licensee's program for maintenance and cali-

bration of equipment being used for performance of inservice in-

spection.

The equipment being used is certified as being properly calibrated.

j

Each certification contains a valid signature with date stating

l

type of equipment, serial number of equipment, and date equipment

iDGW

was calibrated. No deficiencies were noted.

All penetrant materials being used were certified by chemical anal-

ysis which recorded total amounts of sup1hur and halogen. No

deficiencies were noted.

6.

Eddy Current Inspection on Poison Blades

Eddy Current Inspection was performed on fif ty percent of the

poison control blades by the licensee's contract inspection agency.

The test was performed to determine if inverted sheaths were present.

Preliminary results reveal certain sheaths do contain inverted

tubes. The licensee informed the inspector at least one sheath

would be removed and replaced during this outage.

Evaluation is

being performed to determine disposition of other sheaths which may

contain inverted tubes. The eddy current method of inspecting

sheaths for inverted tubes is a positive method of inspection when

the inspection reveals acceptable conditions, however further

evaluation is required to determine disposition of tubes which

tests indicate may be inverted. No discrepancies were noted.

The inspector reviewed the repair program presently in progress on

welds in the moisture separator. This review included a visual

'

inspection by the inspector. Numerous linear indications were

.

rejected by the licensee's contract inspection agency due to their

j;(;s

location in the Inlet welds, Outlet welds and base material adja-

-

cent to welds. It was noted that all indications required a mini-

mum amount of surface removal (1/8" max.) to eliminate the re-

jectable indications. No deficiencies were noted in the. repair

program.
