Licensee Action on Previous Inspection Findings (Closed) Violation (424/81-09-01 and 425/81-09-01):
Failure to Maintain -
Sufficient QA Records in the - Area of Concrete Testin" The inspector examined-the licensee's response to this violation dated November 3,1981 and' implementation of the corrective action stated in the response. The inspector reviewed the Concrete Testing Pour Test Part I form.
This form has been revised to include a block for the inspector performing the
,
cylinder strength test ' to _ initial.
The inspector reviewed completed test
records for concrete mix numbers 411 and 511 tested in December 1981 and verified that this block is being used to record the identification of inspectors performing the concrete cylinder strength test. 'The licensee instructed inspectors who perform ir, process tests (slump, air, and unit l
weight) on plastic concrete to initial the Concrete Placement Pour Log form.
l The inspector reviewed selected Concrete Placement Pour Logs for some
concrete placements made in December 1981 and verified that the identi-fication of inspector performing the in process tests on plastic concrete is
being recorded on these records. This item is closed.

-f.
Stop Work Notices SW-C-01 through SW-C-34 and SW-C-36 through SW-C-39.
The inspector made a detailed review of the corrective action to disposition stop work notice number SW-C-39 which was written to stop concrete placement in the power block. The corrective action included
,
l retraining of craft personnel, re-emphasis of concrete placement i
~ inspection requirements to civil QC inspectors, and implementation of a l
periodic (approximately once a week) critique of a ' selected concrete
'
placement to identify and correct problems dealing with placement and inspection of concrete. The retraining of personnel was completed the day after the stop work order was written. The inspector discussed the
'
reasons for the stop work order and the corrective actions with QC and management personnel.
This item was reviewed by the licensee's QA staff who determined that it was not reportable to NRC. The inspector
concurs with this finding.

PSAR Section 3.8.
The inspector verified that the reinforcing steel was installed ' for the~.
primary shield wall pour as per the requirements shown on the drawings, FCRs and DCNs. The inspector measured spacing of the rebar, and distance from the face of the forms to the rebar. The inspector verified that'the proper number and size of bars had been installed.
The inspector discussed inspector requirements and acceptance criteria used in the rebar inspection with the civil QC inspectors responsible for performing the primary shield wall reinforcing steel inspections. The inspector verified that QC inspec-turs were using the current revisions of the drawings in performance of '
their inspections.
During observation of the concrete placements, the inspector verified forms were tight and clean, and that rebar and embeds were securely anchored an'd clean.
Placement activities pertaining to delivery time, free fall, flow distance and consolidation conformed to procedure requirements.
Concrete placement activities were continuously monitored by QC inspectors. Exami-nation of batch tickets indicated that the specified design mix was being delivered.
Samples of plastic cor. rete were - being obtained from the con-crete truck and tested in accordance with procedure requirements. Samples
...
.-...
of plastic concrete were also being obtained from the pumpline discharge for correlation testing.
Test results indicated that plastic concrete being placed met the procedure requirements for slump, air content, and temperature.
QC inspectors were interviewed regarding procedure and their inspection requirements.
No violations or deviations were identified.
