that he felt that because the problem had been identified and corrected
(the paper was removed), no further action was necessary.
Bechtel
has procedures which allow for reporting of deviations from accepted
practices,. These nonconformance reports (NCR's) are completed when
certain criteria are met.
The criteria were not specific regarding
a wad of purge paper found in a pipe.
However, had an NCR been
initiated by either the radiographer (when he saw what eppeared to
_
be paper on the film on May 16, 1979) the lead QC Welding Engineer
or the other QC Welding Inspector, the licensee would have become
-
aware of the situation much earlier.
On June 7, 1979, while performing routine inspection activities, the
NRC Resident Inspector overheard a conversation between the Authorized
Inspector and other unidentified individuals. After obtaining the
above mentioned information, he questioned the licensee's Quality
Control Department and discovered that they had not been informed of
the incident. The initial reports received by the NRC Resident
Inspector indicated that the ball of paper would not dissolve in
water. An additional test of the paper was made and it was found to
be water soluble.
The licensee began an imme(: ate investigation to determine the
circumstances. At the request of the licensee, the BPCo QC Welding
Inspector, who found the " reject" tag on the weld and witnessed the
removal of the paper ball, prepared a " Field Inspection Report" on
June 7, 1979.
As a result, the contractor initiated three " Quality Action Requests"
(QAR) on June 8, 1979, to document the identified problems and
corrective actions. These QAR's are sent from the contractor's Quality
Assurance Organization to responsible departments and licensee personnel
in order to receive information regarding the subject of the QAR:
a.
QAR SD-207, completed July 3, 1979, Subject:
Improper use of
Water Soluble Purge Dam.
This QAR requests that the situation
be reviewed to determine if it is formally reportable to the
NRC as required by 10 CFR 50.55(e). The determination was made
that because testing procedures require that the spray header
pipe be filled with water to the 745' level (21' above the
point where the ball was found) the paper would have been
submerged and dissolved prior to any actuation of the spray
system. The licensee had verified this information verbally on
June 8, 1979.
b.
QAR SD-208, completed June 22, 1979: This QAR requested that a
-
determination be made as to why a nonconformance report (NCR)
was not issued to document the presence of foreign material in
@;
a piping system and document the violation of Note 3, Sheet of
GPS-1, Rev. 4.
The determination was made that a NCR should
have been initiated at the time the paper was noted on the
radiograph and that a Field Inspection Report should have been
