SUMMARY
SHEET CONTROL OF WELDING PILLER MATERIAL AT BROWNS FERRY NUCLEAR PLANT I.
SCOPE OF EVALUATION This report addrosses sixteen employee concerns dealing with the
{
control and quality of welding filler material used in safety related i
applications at Browns Ferry Nuclear Plant. These concerns were grouped into four issues to aid in the evaluation effort.
A.
Lack of portable rod ovens to protect coated electrodes from moisture absorption, B.
Inadequate control of weld rod.
i C.
foor quality E-7018 electrodes.
D.
Administrative pre.etices for return of filler material.
II. ANALYSIS OF ISSUES ADDRESSED BY CONCERNS BACKGROUND The Browns Ferry Nuclear Plant was largely completed prior to the provisions of 10CFR50. Appendix B becoming mandatory.
In 1972. TVA constitted to compliance with Appendix B.
The program in place at that time met the regulatory requirement, and continued to do so throughout the rtmainder of construction.
The filler material controls emplaced during construction were also implemented for operations and continue l
to satisfy ANSI /AWS D1.1 and ASME Sections III and XI.
ISSUES A.
The issue of portable rod ovens not being used to prevent moisture absorption by coated electrodes evolved from a procedure change at Watts Bar Nuclear plant (WBN).
In early 1982. TVA at WBN took advantage of a change to the Structural Welding Code which extended the allowable atmospheric ouposure time for coated electrodes.
This new method relied upon certain tests specified by the code.
The use of portable ovens became unnecessary.
11620 Page 1 of 4 l
L VP-01-BFN Revision 0 During construction. TVA at Browns Ferry adhered to the originally specified exposure limits rather than the use of portable ovens.
Operations continues to rely on the exposure limits for most electrodes. Portable rod ovens are used for certain hign strength low alloy electrodes, because of very short exposure limits.
This issue is discussed in detail in the technical report (WP-01-BFN) Paragraph III A.
8.
For ease of discussion, the issue relating to inadequate control of filler material is presented in three parts.
1.
Two of the concerns indicate that welders had obtained weld filler material from other welders rather than from the control points.
No evidence was found to prove or disprove the factuality of these concerns.
If factual, they would reflect isolated occurrences of individuals violating the BFN procedures.
Additionally, no evidence was found to indicate either that unqualified personnel performed welding operations, or that welders cousumed material other than the specified type for the work being performed.
lg(
A detailed discussion of this issue may be found in Paragraph III B.1 of WP-01-BFN.
2.
Two of the concerns state that steamfitters and sub-journeymen are allowed to check out and return filler material.
Both the Construction and the Operations procedures at Browns Ferry have consistently required that weld filler material be issued only to certified welders, except in controlled special circumstances. When a welder is in a contaminated area, the Foreman or General Foreman may obtain the filler material for the welder.
Coniplete details of the evaluation of this issue are addressed in Paragraph III B.2 of WP-01-BFN.
3.
Four concerns state that weld rod and rod stubs are not adequately accounted for.
During construction, rod stub accountability was not required.
The Modification / Addition procedure. BFN MAI-12, first required full accountability by the welder for all material issued.
11620 Page 2 of 4 l
WP-01-BFN Revision 0 C
Accounting for waste and unused filler metal is a good construction practice which should be linplemented to the extent p;'acticable.
It is not, however, a requirement of the ASME or AWS codes.
It must be recognized that absolute control of waste and unused filler metal is unlikely to be achieved in any large construction effort.
Accountability of waste and unused filler metal is discussed in WP-01-BFN, Paragraph III 8.3.
i C.
One concern states that E-7018 electrodes are of poor quality.
which causes porosity and pinholes.
l This issue has not been a problem at Browns Ferry. There was one l
lot of E-7018 electrodes at Watts Bar which was returned to the vendor for a concentricity problem. These electrodes were not issued to Browns Ferry.
The quality of E-7018 electrodes is discussed in detail in WP-01-BFN, Paragraph III C.
D.
Three concerns relate to administrative practices. The concerns i
are that the welders receive no evidence to verify that unused weld j
filler material and/or stub lengths are turned in.
This creates t
{(k the possibility of unwarranted disciplinary action.
These concerns have no welding related technical significance.
The issue is generically evaluated in Subcategory 70200, Work Rules, i
and is not addressed further by this report.
l III. COLLECTIVE SIGNIFICANCE The employee concerns addressed by this evaluation have no adverse hardware or programmatic effect at Browns Ferry Nuclear Plant.
The Browns Ferry program for control cf welding filler materials is in l
Place and meets the requirements of ANSI /AWS D1.1, Section 4. ASME Section III, NB-4000, and ASME Section XI, IWB-4000.
The quality of coated electrodes purchased for use at BFN meets the requirements of ASME Secticas II and III.
IV.
ROOT CAUSE The reason for the employee concerns relating to welding filler material at BFN is the application of Watts Bar employee concerns to other TVA nuclear sitos for evaluation for generic applicability.
V.
CORRECTIVE ACTION t
No corrective action is indicated.

- a BFN Revision 0 i
The Browns Ferry Nuclear Plant was largely completed prior to the provisions of 10CFR50, Appendix B becoming mandatory.
Notwithstanding the fact that the material issues raised by the concerns were not subject to regulation for most of the construction 1
period, the evaluation revealed that TVA at BFN d!d have in place a program for control of welding filler material which met the letter and intent of the code of record.
At the beginning of construction, the control of welding filler material was by direct application of the provisions of The American Welding Society Code for Welding in Building Construction, AWS D1.0 l
under the control of the Mechanical Engineer.
The Quality Control Handbook was implemented in 1968. The level of specific detail one would expect to find in today's control systems was not in this early BFN procedure manual.
There was, however, sufficient detail to show that weld filler material control was in compliance with The Code for Welding in Building Construction.
In 1972 TVA committed to compliance with Appendir B.
The program in place at that time met the regulatory requirement, and continued to do so throughout the remainder of construction.
Control of weld l
filler material met the requirements of The American Welding Society Structural Welding Code, AWS D1.1, which replaced AWS D1.0.
A review of the superceded procedures and the c'terent Site Director's Standard Practices for BFN shows that the fille 6 wterial controls emplaced during construction wero also implemented for operations and continue to satisfy ANSI /AWS D1.1 and ASME Sections III and XI.
ISSUES A.
Six concerns state that portable red ovens were not used to prevent moisture absorption by coated electrodes.
Had these concerns originated at Browns Ferry, they would be factual. They do not, however, represent a proolem, in that atmospheric exposure of low hydrogen electrodes has consistently been restricted to the limits prescribed by AWS D1.1, throughout construction and operation.
In the early construction era, drying ovens were placed in the work areas to protect coated electrodes.
The welders were then issued small quantities which could be consumed within the four hour limit. The Foreman was responsible to ensure that the procedure was followed.
Surveillance was regularly performed by r
l Construction Engineering personnel to ensure that the system for protection of coated electrodes was properly implemented.
Procedure BF-44. Welding Material Control, provided the necessary instructions.
11630 Page 2 of 6 L
YP-01-BFN uavision 0 I
The filler material control during operation was initially implemented through separate controlled instructions for I
Maintenance and for Modifications.
These instructions were superceded by Site Director's Standard Practices (SDSP), which currently control all welding on the Browns Ferry Plant.
The current SDSP 13.2 provides all of the controls necessary to comply with the Structural Welding Code. SDSP 13.2 makes provisions for use of portable rod ovens for E-80XX, E-90XX, E-100XX and E-110XX coated electrodes.
E-70XX electrodes are not required to be issued in portable ovens. Rather, the exposure limits of AWS D1.1 are adhered to.
Coated electrodes returned
'he prescribed time limit are disposed of.
B.
dight concerns relate to general control of welding filler material.
1.
Two of the concerns indicate that welders had obtained weld filler material from other welders rather than from the control points.
The Watts Bar concerns relating to welders receiving weld filler material from other welders were evaluated to be isolated instances of individuals violating the procedure.
l g-km In evaluation of these concerns, no evidence was found to indicate either that unqualified personnel performed welding operations or that welders consumed material other than the specified type for the work being performed.
Review of the Browns Ferry construction era procedures provides reasonable assurance that even if similar instances had occurred at BFN, they too would have been isolated occurrences.
Procedures BF-44, Welding Material Control, and BF-45, Weld Quality Assurance Program for Piping, provided the necessary programmatic controls to ensure that this was not a widespread practice.
For operations, Browns Ferry Standard Practice BF 6.2, Quality Control of Welding, required in part "During or prior to weld joint fit-up inspection the QC Inspector shall verify correct filler material is being used."
BF 6.2 was superceded by SDSP 13.1, which incorporates the same requirements at 6.3.2.4.
2.
Two of the concerns state the steamfitters and sub-journeymen j
are allowed to check out and return filler material.
l These two concerns were based on fact at Watts Bar, where the l
procedure provided for welders' helpers checking out the l
filler raaterial.
l l
l 11630 Page 3 of 6
WP-01-BFN Revision 0 Both the Construction and the Operations procedures at Browns Ferry have consistently required that weld filler material be issued only to certified welders, except in controlled circumstances.
Procedure BF MAI-12, at 4.1 provided in part that when a welder is in a "C" zone (contaminated area), the Foreman or General Foreman may obtain the filler material for the welder. This provision is currently in Site Director's Standard Practice (SDSP) 13.2, Paragraph 6.6.2.3.
3.
Four concerns state that weld rod and rod stubs are not adequately accounted for.
Had these concerns originated at BFN during construction, they might have been factual.
Procedure BF-44, Welding Material Control, did not address accountability of unused or waste filler material.
BF-44 required destruction of material which exceeo2d the exposure time limit, but was unclear as to who was responsible for the destruction.
Disposition of waste was not addressed.
The Modification / Addition procedure, BF MAI-12, at 4.1
{(
required full accountability by the welder for all material
(
issued. The exception was where filler had been contaminated, in which case verification was required via a "contamination slip."
The current SDSP 13.2, at 6.2 makes the same requirement.
It should be noted that there is no code or regulatory requirement to account for each piece of unused or waste welding filler material.
It is recognized throughout the nuclear construction industry that control of waste and unused weld rod is a good construction practice, but absolute i
piece by piece accountability is virtually impossible.
C.
One concern states that E 7018 electrodes are of poor quality, which causes porosity and pinholes.
Discussion with cognizant TVA Welding personnel indicates that this issue was never a problem at Browns Ferry.
There was one lot of 3/32 diameter E-7018 electrodes at Watts Bar which was returned to AIRCO for a concentricity problem.
l Review of Corrective Action Reports, Deficiency / Deviation /
Nonconformance Reports, USNRC Inspection Reports, Quality Assurance Audit Reports, and TVA welding related memoranda issued from 1972 through 1985 failed to provide any indication of a problem with weld filler material at BFN.
Neither did this review show that porosity was ever a recurring problem at BFN.
t l
11630 Page 4 of 6
WP-01-BFN Revision 0 All welding material used for permanent plant features at Browns Ferry is purchased in accordance with the ASME Boiler and Pressure Vessel Code,Section II, Part C, SFA specifications and the additional requirements of ASME Section III, Subsection NB.
Tests must be performed in accordance with SFA specifications on each heat and lot number of weld filler material manufactured to assure acceptability for use.
These tests include radiographic soundness requirements, usability of the electrode, and appearance cf the weld, i.e., weld surface contour and smoothness, undercut, overlap, size, and resistance to cracking.
Also, a Certified Mill Test Report (CMTR) is dispatched along with each shipment of weld filler material attesting to compliance with material specificationa.
Additionally, the Division of Construction i,0v the Division of Nuclear Construction) requires a series of e;erability tests prior to award of a contract to supply coated electrodes. These tests include the tendency of the electrode to promote porosity due to moisture content of the coating, improper shleiding or improper deoxidation. The tests are required for all products without a previously demonstrated history of satisfactory performance by TVA.
D.
Three concerns relate to administrative practices.
The concerns are that the welders receive no evidence to verify that unused weld filler material and/or stub lengths are turned in. This creates the possibility of unwarranted disciplinary action.
These concerns have no welding related technical significance.
The issue is generically addressed in Subcategory 70200, Work Rules.
IV.
COLLECTIVE SIGNIFICANCE The employee concerns addressed by this evaluation have no adverse hardware or progrimmatic effect at Browns Ferry Nuclear Plant.
The Browns Ferry program for' control of welding filler materials is in place and meets the requirements of ANSI /AWS D1.1, Section 4. ASME Sectioa III, NS-4000, and ASME Section XI. IVB-4000. The quality of coated electrodes purchased for use at. BFN meets the requirements of ASME Sections II and III.
V.
ROOT CAUSE The reason for the employee concerns relating to welding filler material at BFN is the generic application of Watts Bar employee concerns to other TVA nuclear sites for evaluacion for generic applicability.
VI.
CORRECTIVE ACTION No corrective action is indicated.
