icensee action on previous inspection indings and preservice inspection activities including NDE procedure qualification, program review, NDE data review and observation of work in pro-gress.
The inspection involved 21 inspector'-hours onsite by one NRC regional based inspector.
'esults:
Of. the five areas inspected, no items of noncompliance were identified
~sn our areas; one apparent item of noncompliance (infraction - failure to follow approved procedure during ultrasonic examination of piping welds - Para-graph 5) was identified in one area.

'L'icensee Action on'Previous'ns ection'Findin s
(Open) Unresolved Item (387/80-03-01) - Use of radiography for volumetric examination of welds.
The licensee has increased from 8 to 19 the number of welds scheduled for radiographic examination to satisfy the preservice inspection 'volumetric examination requirements, of the ASME Code, Section Xl.
This matter remains open pending a determination by the licensee of the ability.to radiographically examine the welds after the plant becomes operationa..
(Closed)
Unresolved Item (387/80-03-02) - Use of instrument reject.
The licensee's response to the item states that the instrument reject control will not be used unless the instrument linearity is verified at the reject setting intended for use and that test system calibration will be. checked at the reject. setting.
The inspector confirmed that the above ar'e proce-dural requirements..
The inspector had no. further questions on this matter; Nondestructive Examination'Procedure uglification The inspector witnessed the qualification test. done by the NES site super-visor for liquid penetrant: examination procedure number 80A2775, and for the angle beam examination. requirements of ultrasonic examination procedure number 80A2771,'revision 2.. The procedure qualification was done to satisfy the. requirements of IWA2120, ASME Code, Section Xl.
'I The penetrant procedure qualification was done by performing a penetrant examination in accordance with the procedure using an aluminum test block.
The procedure was considered qualified when the test block defects were satisfactorily detected.
The ultrasonic examination procedure qualification was done usinq-a Sonic MKI instrument, serial number 783107 and a 2.25 MHz, 4" x >", 45 trans-ducer, serial number 016446.
The procedure was considered. qualified when ID and OD square notches were satisfactorily resolved i'n calibration block number SSES-24-153-CS, nominal thickness equal to 1.531"
~
The procedure is intended for the examination of piping welds ranging in thickness'rom 0.280" to 1.812".
No items of noncompliance were identified.
4. 'reservice'ns ection'PSI'Pro ram The completed portions'of the PSI program were previously reviewed (IE Inspection Report No. 387/80-03).
The inspector found that, the program is being implemented in those areas which have licensee approval.
The inspector found that the PSI program is still incomplete and that no completion date was-available at the time of this inspection.
This is considered unresolved pending availability and NRC review of the completed PSI program.
(387/80-09-01)
Ultrasonic Examination'of'Pi in Melds Interviews with licensee contractor personnel and observations by the inspector indicated that a procedure requirement may have been omitted when ultrasonically examining certain piping welds in the residual heat removal (RHR) system..
The inspector reviewed the available ultrasonic calibration records for RHR system welds to determine whether the examinations were done in accordance with the applicable sections of NES procedure number 80A2771, the governing procedure,.
and to ascertain
.that the scan areas identified on the data sheets were scanned at the required calibration sensitivity level.
Calibration data sheet number 2771-1 and number 2771-4 for the following RHR system welds were reviewed by the inspector:
GBB-110-1-28,-2C,-2D, 3A"; -3E',. -4B,. -5C, and-5D GBB-104-1-FW1,-1C,-FW2,-FW3,-3B,-4A,-FW-5,-5B,-7C,-FW8,-,FW9 and FW10 The reviewed records indicated that the base material scan using a 0
,
straight beam transducer was done at an improper calibration sensitivity level
.
Procedure 80A2771 requires that the base material through which angle beams must pass shall be scanned using a straight beam transducer.
The scan is intended to detect conditions in the base material which will interfere with angle beam examination and influence interpretation of the results.
The required sensitivity level is such that an 80Ã of full screen (FSH)
back reflection is displayed on the cathode ray tube (CRT) screen from the piping being examined.
As evidenced by the aforementioned data sheets, the inspector found that licensee contractor personnel performed the straight beam, base material scan for interfering conditions at a sensitivity level based on side drilled hole calibration and not the back reflection required by the governing procedure.
He found, also, that this was done under instructions from the NES site supervisor and a
NES level III individual.
The side drilled hole calibration resulted in a sensitivity level and a
CRT screen display which would preclude reporting per section 8.1.1 of proce-dure number 80A277 While the. inspector was at the site,. the licensee contractor level III initiated Field Change number FC-2 to procedure 80A2771 which revised the calibration data sheet to include verification that the straight-beam, base material scan was done in accordance with the-procedure.
The change was i'ntended's part of the corrective action to'preclude further procedural violations as 'described above.
Failure to follow a prescribed procedure for the ultrasonic examination of piping welds is contrary to the requirements of 10 CFR 50, Appendix B,.

'Unresolved Items.
Unresolved items are items about which more information is required to ascertain whether they are acceptable items, items of noncompliance or deviations.
An unresolved item disclosed during this inspection is dis-cussed in paragr'aph.3.
7.. 'xit Interview The inspector met with the licensee representatives (denoted in Paragraph 1) at the conclusion of the inspection on May 9, 1980.
The inspector summarized the purpose and the scope of the inspection and the findings.
In addition to those denoted in paragraph 1, the NRC senior resident inspector, Mr. R. Gallo, and the NRC resident inspector, Mr.,G. Rhoads, attended the exit meeting.
