,

With regard to the inspection above, the inspector noted the

following:

-

The welder of record for support V2-122A-174-H642, Rev. O,

<

was assigned Welding Procedure Specification (WPS)

.

27-III/I-8-08-12, Rev 4/14/83, had drawn welder filler

!

material 3/32-inch diameter and had his welding machine set

'

at 35 amps. Had the NRC inspector not questioned the welder

regarding welding parameters, the welder would have completed

the weld joint using 3/32-inch diameter welding filler

i material with 35 amps, contrary to the assigned WPS,

i 27-III/I-8-0B-12 which specifies a welding current range of

j 100-150 amps for use with 3/32-inch diameter filler material.

1 The inspector discussed the above with the licensee who

3

agreed that the welder deviated from the assigned welding

'

procedure specification without proper authorization.

-

Drawing M0lG-S400, Rev, at E7, for the connection of Pc.A to

Pc.C, requires a complete penetration double bevel groove

weld to be made where the end of a square tube steel section

butts against the side of second square tube section of the

,

'

same size. The welding symbol on the drawing is improper for

two reasons. First, the joint is a flair bevel weld due to

the radius on the tube steel section, not a double bevel

i groove weld, and second it is not possible to make a weld on

I the inside of the tube steel on the second bevel face.

Ingals welders prepared and welded the joint with flair bevel

!

joint preparation. The inspector discussed the above with

! Georgia Power Company (GPC) QC inspector responsible for the

Ingals shop who indicated that the drawing was in error and

that a flair bevel was " intended". The GPC QC inspector

further stated that he had accepted many other weld joint

fit-ups with the same deviation from drawing weld symbol

!

requirement because the flair bevel was " intended" by the

designer. The GPC QC inspector stated that there was no

documentation to support the " designer's intentions".

This NRC inspector discussed the above with the licensee,

indicating that QC inspectors function is to inspect, accept

or reject and document their findings based on actual

documented requirements, and not to accept work that deviates

from actual documented requirements based on undocumented

information or knowledge.

The above indicates that the welder failed to follow the

welding procedure specification. The designer provided a

drawing with an inappropriate acceptance criteria (weld

symbol), and the QC inspector accepted work that deviated

' om documented requirements. Failure to follow documented

.

3rocedure and drawing requirements for activities affecting

quality and failure to provide appropriate acceptance

criteria for activities affecting quality is a violation of

10 CFR 50 Appendix B, Criteria V. This violation will be

identified as 424/85-60-01 and 425/85-40-01: " Failure To

Comply With Welding Requirements".

.

(2) Welder Qualification (551578)

The inspector reviewed the licensee's program for qualification of

welders and welding operators for compliance with QA procedures

and ASME Code requirements. The applicable code for weldor

qualification is ASME B&PV Code Section IX as invoked by GPC

Specification X2AG06 Rev. 4 and X4AXZ01, Section P.1.

The inspector observed the following inprocess performance

qualification tests to determine whether the testing was

consistent with the code and regulatory requirements. The

inspector confirmed by positive identification that the person

welding the test weldment was indeed the person being qualified.

CB&I - Welder WLS, WPS-E7018/33710, Rev. 1

(3) Weld Heat Treatment (551568)

Weld Joint Preheating

(a) The inspector reviewed the licensee's program to determine

whether procedures properly specify acceptable preheating

methods, provide requirements for monitoring and recording

preheat temperature before, during, and if specified, after

welding, and whether specified temperature control is

utilized on in-process welds which are required to be

maintained at pre-heat for extended time periods.

. . - . . .. - __ .

.

8

(b) By direct observation and review of records, the inspector

observed / reviewed the preheating activities for the weld

joints listed in paragraph 6b(1) to determine whether preheat

control procedures were being following during field welding

activities.

Within the areas examined, no violations or deviations were identified

except as noted in paragraph 6 b(1).

!

7. Safety-Related Heating, Ventilating, and Air Conditioning (HVAC) Systems

(50100)

l The inspector reviewed the licensee's HVAC program to determine whether the

,

technical requirements detailed or referenced in the facility Safety

a

Analysis Report associated with safety-related HVAC systems had been

adequately addressed in the construction specifications, drawings, and work

procedures. The applicable codes for the fabrication and installation of

HVAC systems are:

AWS-D1.1-77

AWS-09.1-80

AWS-D3.0-77

"

. ASME Section IX-80

ANSI B31.1-77

Observation of Work and Work Activities

a. Personnel Interviews (Installation Practices)

The inspector interviewed six craftsmen engaged in the installation of

seismic supports, and duct work, to confirm the following:

-

Predefined and approved procedures are followed when it becomes

,

necessary to relocate any seismic support or other safety-related

,

equipment from its original location specified on drawings.

-

Any preinstallation field repairs or adjustments to the HVAC

equipment are performed in accordance with the manufacturer's

instructions and specifications to ensure that proper materials,

replacement parts, and supplies are used, performance requirements

are met and are reviewed by engineering for acceptance.

- Personnel engaged in the installation and inspection of safety-

related supports, ductwork, and other safety-related HVAC equip-

ment have received adequate training to understand and perform

work contained in relevant work and inspection procedures and

instructions.

b. Installation Activities

,

The inspector witnessed portions of the installation activities

indicated below +o verify the following:

- The latest issue (revision) of applicable drawings or procedures

is available to the installers and is being used.

- Modifications to supports are approved by appropriate personnel

<

before implementation.

i With regard to the inspection above, the inspector noted that P/K-F

4 Drawing AX2D67W013 revision 6 on P/K-F 6700W Stick No. 2 was missing

FCRB-2775F dated 12/6/85. Examination of the drawing indicated that

the FCRB had never been attached. The above is contrary to P/K-F

Procedures JP-6.1, Rev. 9c, " Document Control" paragraph 6.1.3D and

i JP-3.1 Revision 10a, "D . ign Control" paragraph 4.5, which require

j FCRBs to be distributeo and posted to the applicable drawings

! immediately. At the time of this inspection, this FCRB was 13 days

old. The inspector, could not determine daring this inspection the

!

-

extent of unposted drawing charges. Pending further NRC inspection in ,

this area, this matter will be identified as unresolved item l

!

424/85-60-02 and 425/85-40-02: "Unposted Drawing Change Documents".

Within the areas examined, no vio?ations or deviations were identified.
