Investigation of Allegation 1.
Allegation It was alleged that the Bechtel second shift foreman in the primary containment instructed his men on different occasions to deviate from the requirements in Bechtel's procedures for welding.
The specific allegation was as follows: The foreman told more than one person (pipe fitters) to peen -- over porosity, rather than grinding.
The foreman told more than one person (pipe weldors) to weld -- without the weld authorization papers (release to weld).
The foreman, when told by a pipe weldor of a crack that was -- approximately 8 inches long in the pipe restraint he was welding, denied it was a crack and told the pipe weldor to weld over it.
The pipe weldor refused to do this, and the foreman then told him to grind out the crack, although Bechtel's procedure require the quality control engineer is to be informed of such an indication prior to doing any repairs.
The weldor started to grind out the crack, but the QC engineer, during his inspection tour, noted the grinding and stopped further grinding.
A nonconformance report was issued for this crack.
2.
NRC Investigation The allegation, as understood by NRC, pertained to statements orally by a foreman.
Direct confirmation of the allegation could be made only by persons who may have heard the alleged statements.
Therefore, the NRC investigators held interviews and discussions ~ with the various Bechtel personnel on the second shift who were or might have been ir.volved with the foreman, who worked on the second shift.
The nature of the allegation was such that, if correct, it might result in welds which fail to meet requirements.
The investigators examined welds in process and records, including non-destructive examination records, of completed welds that were made under the jurisdiction of the foreman in question.
The interviews revealed some dissatisfaction of workers with the performance of the foreman, including some at last partial confirmation of the allegation.
However, the interviews did not reveal information . which would confirm an actual or probable adverse impact on ' quality by the foreman's words or actions.
I i
s .
. The review of welds and welding records did not reveal nonconforming conditions related to the allegation.
No items of noncompliance were identified.
