2 Independent Inspection Effort i

Construction Progress The inspector conducted a general inspection of Unit I reactor building to observe construction progress and construction activities such as welding, material handling and control, housekeeping and storag Within the areas examined, no violations or deviations were identifie . Inservice Inspection - Observation of Work and Work Activities (Unit 1)

(73753B)

The inspector observed the ISI activities described below to determine whether these activities were being performed in accordance with regulatory requirements and licensee procedures. The applicable code is the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel (B&pV) Code,Section XI, 1980 edition with addendas through winter

'

1981 (see RII Report 50-325, 324/87-04 for the initial inspection of this area during this outage).

As noted in RII Report 50-325, 324/87-04 the licensee is currently in the 5th reload outage for Brunswick - Unit 1. During the inspector's first examination of the licensee's ISI and Repair Welding Activities the inspector reviewed the programs, procedures, personnei qualifications and observed a limited amount of the in process work activitie This inspection the inspector directed his efforts entirely to the surveillance

, of in process work activities. The following nondestructive examinations and repair welding activitios were observed- Magnetic Particle Examination (57070)

i The inspector observed magnetic particle (MT) examiners from Cp&L's i Corporate Quality Assurance Department (Materials and Quality l

Section) perform the MT examination of the reactor pressure vessel l

head to flange weld. The inspector observed the above examination to j

ascertain whether the following requirements were met:

-

An approved nondestructive examination procedure was available and being followed

-

The specified equipment was being used

-

The NDE personnel were knowledgeable of the examination n:ethod l and the correct operation of the equipment

- The NDE personnel performing the examination were certified to the proper level for interpretation, evaluation, and acceptance of the test results

. .

.

In addition to the above the inspector observed the examination to determine if the following test attributes were consistent with the approved procedure and Section XI of the ASME Cod Material surface preparation / cleanliness was satisfactory

-

' Type and color of ferromagnetic particles were correct

-

Examination technique / coverage were adequate

-

Pole spacing /usuage correct

-

Continuous method used

.

-

Results were consistent with the acceptance criteria b. Visual Examination (57050)

1he inspector observed General Electric (GE) visual examiners perform the invessel visual examination of the following components:

-

Feedwater spargers and wall brackets

-

Core spray sparger, upper, starting at 908 azimuth rotating clockwise to 270' azimuth and 270* azimuth rotating to 90*

azimuth - 3rd pass

-

Core spray sparger, lower, starting at 90* azimuth rotating clockwise to 270* azimuth-3rd pas The inspector observed the above examinations to determine through direct observation whether the visual examinations were being conducted by properly qualified personnel in accordance with procedures and the licensee's/ contractor's approved QA program. The examinations were conducted in accordance with the Brunswick Period Test Procedure PT-90.5 entitled: "In Vessel Visual Examination".

The specific visual examinations methods, techniques and acceptance were to ASME Code, VT-1 and VT-3 requirements as described in CP&L's visual procedures NDEP-611 Rev. 4 and NDEP-613 Rev. 5. The inspector also observed the performance of the visual examination to determine that the following conditions were addressed in a satisfactory manner:

-

The applicable drawings instructions and a copy of the procedure was available in the area where the work was being performed

-

Personnel performing the examinations were qualified to perform the assigned task

-

The required tools and examinations aids were available at the work location i

. .

.

_

-

Lighting was sufficient to clearly observe the examination surfaces

-

The specific areas, locations and extent of examination were clearly defined

- Defects were evaluated in accordance with the procedure requirements, correct acceptance criteria was used and the inspection results were reported in a prescribed manne c. Ultrasonic Examination (57080)

The inspector observed GE's ultrasonic examiners perform the following intergrannular stress corrosion cracking (IGSCC)

examinations in accordance with NRC Generic Letter 84-11 and NRC Information Notice 84-41. GE was conducting the IGSCC examinations utilizing their automated ultrasonic system commonly referred to as the SMART System. All of the ultrasonic examiners involved in the examination had been cert 1fted to the proper ievel in accordance with the EPRI/BWROG/NRC Training and Qualification Agreemen The following examinations were observed:

,

'

(1) Type of apparatus used, including frequency range, linearity and signal attention accuracy (2) Extent of coverage as well as the scanning technique l (3) Calibration methods (4) Size, frequency and sound wave mode of Transducer (5) Beam angles

(6) Reference level for monitoring discontinuation

The inspector observed in process welding for the following weld overlay repairs:

Weld N AR-C-2 28A-14 12AR-D-4 12AR-A-2

.

12AR-B-3 The inspector observed the above welding to determine through direct observation whether the welding activities were performed in accordance with the ASME Code and licensee commitments.

i Within the areas examined,no violations or deviations were identifie . Inspector Followup Items (IFI) (92701)

(Closed) IFI 324/85-10-02, Verifying Adequate Examination Coverage of

. Welds Examined During Unit 2, Generic Lattar A4-11 avaminations. noring the Unit 2, December 1985 outage CP&L reinspected the overlay welds to determine if discrepancies in examination coverage existed. The welds not meeting full examination coverage were repaired in accordance with Plant Modification No. 85-03 (Closed) IFI 324/86-10-02 and 325/86-09-01, Technical Specification Change for Jet Pump Monitoring. Cp&L's letter (NLS-86-225) dated March 13, 1987 was sent to NRC requesting a license amendment to the jet pump

,

surveillance requirements. This action is satisfactory and the item is I

considered close Within the areas examined, no violations or deviations were identified.
