SUMMARY
SMEET '
WELDER TRAINING AND EXPERIENCE' AT BROWNS FERRY NUCLEAR PLANT l
t I. SCOPE OF EVALUATION l
This report addresses three employee concerns dealing with the training and experience of welders employed in safety related applications at i Browns Ferry Nuclear Plant (BFN). These concerns were grouped into two issues to aid in the evaluation effort.
A. Qualification and experience of subjourneymen.
B. Adequacy of TVA welder training program.
Text of the three concerns is provided in the technical report (WP-07-BFN) under Attachment 1. ,
II. ANALYSIS OF ISSUES ADDRESSED BY CONCERNS A. The issue relating to the qualification and experience of subjourneymen was raised by one concern which states that subjourneymen are used to perform tasks for which they are not qualified, that they are not required to have specific training, that they do work normally done by a journeyman, and that they are not provided adequate technical supervision.
The primary purpose of the subjourneyman position is to free the journeyman from trade related tasks which do not effectively utilize his skills. The TVA practice of allowing the subjourneyman to progress beyond menial tasks as he gair.s experience is corraensurate with similar practices throughout the power construction industry. This practice is not in violation of any of r the applicable codes, standards, or commitments.
A detailed discussion of this issue is presented in the technical '
report (WP-07-BFN), Paragraph III A.
B. Two of the concerns relate to the adequacy of the training and experience of welders trained by TVA.
The TVA welder training program was offered at DFN approximately during the years 1974 through 1976. The length of training was dependent on the progress of the individual trainee.
11820 Page 1 of 2 L
WP-07-BFN Re:ision 0 When sufficient competence was demonstrated, the trainee was tested under the rules of the governing codes AWS D1.1 and/or ASME Section IX in the same manner as a journeyman welder.
Complete details of this issue are discussed in WP-07-BFN, Paragraph III B.
III. COLLECTIVE SIGNIFICANCE No ade.cse effect on hardware or the TVA welding program at Browns Ferry Nuclear Plant was identified. TVA utilization of subjourneymen -
is in accordance with the trade labor agreement and commensurate with management practices throughout the construction industry. The welders trained at BFN vere tested and qualified in accordance with the Structural Walding Code and/or the ASME Boiler and Pressure Vessel Code.
IV. ROOT CAUSE(S)
The reason for the concerns relating to welder training and qualification at Browns Ferry Nuclear Plant is the TVA decision to evaluate concerns initiated at Watts Bar for generic applicability to other nuclear facilities.
- V. CORRECTIVE ACTION l(, No corrective action is required.
VI. REINSPECTION REQUIRED No.
VII. ISSUE CLOSURE Closed.

WP-07-BFN- l Revision 0 l WELDING PROJECT EMPLOYEE CONCERN EVALUATION REPORT l WELDER TRAINING AND EXPERIENCE AT BROWNS FERRY NUCLEAR PLANT I. SCOPE OF EVALUATION This report addresses three employee concerns. Text of the concerns is provided under attachment 1.
The subject concerns were originated at Watts Bar Nuclear Plant (WBN)-
and evaluated for genaric application to Browns Ferry Nuclear Plant (BFN). The expurgated text of the concerr,s was compared with the requirements of the American Welding Society Structural Welding Code and the ASME Boiler and Pressure Vessel Code. The findings presented
- herein are based upon this comparison, redew of the site implementing procedure, and discussion with cognizant 1VA personnel.
II. ISSUES ADDRESSED BY CONCERNS A. Subjourneymen perform work for which they are not qualified and require closer technical supervision than TVA provides.
B. The TVA welder training program does not provide the welder with sufficient training and experience for nuclear installations.
III. ANALYSIS OF ISSUES ADDRESSED BY CONCERNS A. One of the concerns states that subjourneymen are used to perform tasks for which they are not qualified, that they are not required to have specific training, that they do work normelly done by a journeyman, and that they are not provided adequate technical supervision.
- Subjour.7eymen have been utilized in limited numbers at Browns Ferry Nuclear Plant for approximately one year. The primary function of a subjourneyman is to perform the lesser skill tasks associated with the trade, such as material handling.
It is possible for a subjourneyman to progress to actively assisting the craf tsmen in skilled areas. This depends on the same factors associated with the development of any other members of the work force. Thus, an employee with aptitude and motivation will, when glen the opportunity, progress from the mental tasks to those requiring some degree of skill. To not only allow, but to actively promote such -kill development is nothing more than sound management practicc 11830 Page 1 of 3 , ,
. l
.- . 1 WP-07-BFN Revision 0 Discussion with cognizant TVA technical and administrative '
personnel revealed that a subjourneyman may progress beyond the j totally unskilled tasks in a given trade. Relative to subjourneymon, the General Agreement between TVA and the trade jl
$4 unions provides that "TVA shall assign the work to those eLployees ;I who in its judgement are qualified to safely and efficiently l' perform the work." The level of technical supervision required for i any given task depends on the worker. The Foreman is principally l, responsible for assignment of tasks within the demonstrated
{
capability of each worker. He then ensures that the appropriate j technical guidance is provided, on an individual and task basis, to -
each subjourneyman. The journeyman normally provides the direct I supervision and instruction. '
One example givnn in the text of the concern is that subjourneymen I perform welds on 1/4 inch lines. It is possible within the TVA system for a subjourneyman to become a qualified welder by satisfactory performance testing under the rules of AWS Dl.1 and/or ;
ASME Section IX. Subjourneymen have performed welds on 1/4 inch !
and other lines ony af ter becoming properly qualified. '
The primary purpose of the subjourneyman position is to free the journeyman from trade related tasks which do not effectively utilize his skills. The TVA practice of allowing the subjournoyman j(g- to progress beyond menial tasks as he gains experience is commensurate with similar practices throughout the power construction industry. This practice is not in violation of any of the applicable codes, standards or commitments.
B. Two of the concerns relate to the adequacy of the training and experience of welders trained by TVA.
The TVA wolder training program, a voluntary of f-duty course, was offered at BFN approximately during the years 1974 through 1976.
The training was typically 250 to as high as 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> of ;
instruction and supervised hands on training. The length of '
training was dependent on the progross of the individual traineo.
When sufficient competence was demonstrated, the trainee was tested
, under the rules of governing code in the same manner as a
! journeyman welder. The acceptance standards are specified by the codes ( AWS D1.1 and/or ASME Section II) .
There is no code or regulatory requirement which quantifies the l experience required of a wolder. Rather, the governing codes l specify performance qualification testing as a means of assuring l that a wolder is capable of depositing sound weld metal.
