The original assigned weld procedure was adequate for the joint l
configuration of gamma plug weld to pipe as shown on the Maintenance lR3 l
Request (MR).
VI. RECOMMENDATION AND/OR CORRECTIVE ACTION NEEDED Pipe Fabrication Institute Drawing, ES-16, was noted on the data sheet, l
attached to the MR, by Engineering. This is an approved weld joint lR3 configuration drawing for TVA.

EMPLOYEE CONCERN Report Number: WP-22-SON, R3 lR3 Report
Title:
INADEOUATE WELD PROCEDURE I.
SCOPE OF EVALUATION This engineering analysis covers the following SQN concern:
JLH-85-003.
lR3 II.
ISSUE (S) ADDRESSED BY CONCERN Inadequate weld procedure and/or failure to include or reference a weld detail drawing in the work package.
III. CONCERN VALIDITY OR SUBSTANTIATION The Welding Project (WP) has investigated this concern and determined l
that the concern as stated is misleading. The concern was that there I
was not an approved drawing, shown or referenced, for the weld joint I
configuration being used for welding gamma plugs in piping. The weld l
procedure shown on the MR was adequate.
l l
The action taken stated on the concern report is also misleading. The l
weld procedure was not changed on the data sheet. Engineering added a i
note to the data sheet stating " Joint design is for TVA approved standard i
drawing, Pipe Fabrication Institute (PFI) ES-16, (Access Hole and Plug IR3 For Radiograph Access)." This drawing provided the reference required l
by the inspector to determine that TVA had an approved weld joint I
configuration, for the joint in question, that was to be inspected on i
l The statements noted above are based on discussions with the Supervisor l
that initiated the "Onsite Employee Concern Impact Evaluation" and I
the Quality Engineer that resolved the concern with the employee.
l The investigation did substantiate the concern. TVA has an approved weld joint configuration for the gamma plug designs used. However, the 4
Maintenance Request was revised to reference the joint configuration used to resolve the issue. Based upon this investigation, the issue addressed by this employee concern is closed.
