The CB&I Site QC Documents identify a' liner plate anchor stud
pt'31-out which was 'apparently caused by.a la=ination in the
steel plate. This problem is identified as an item of non-
conformance by CB&I; however,-it is not clear that'B&R and TUSI

Plan Progress
The overall plant progress is reported as 7.0% complete.
The second of three mass concrete pours for the Unit 1 containment
building base mat was completed on 9/12/75.
Preparations for the start of installation of reinforcing steel for
Unit 2 containment building base mat is currently in progress.
Constructior activities in other areas of the site appeared to be
progressing as scheduled.
3.
Unit 1 Containment Liner - QA/QC Record Review
'
During this inspectior., the inspector conducted a review of the CB&I
QA/QC Record Documents related to the containment liner installation.
The reactor vessel cavity liner plates, in the containment base mat,
have been installed. Twelve bottom plates and 18 shell plates to the
805' 6" elevation are welded in place. The CB&I work crews are
'
currently off-site and will not return until the containment base mat
concrete has been completed to the 805' 6" elevation.
The inspector reviewed the CB&I QA/QC records accumulated for the liner
p-==
plate installation completed to date.
The records consist of 16 various
forms or drawings prescribed by the CB&I QA Program Manual.
During the review it was observed by the inspector that CB&I, Form 681,
"Nonconformance Control List", Itea #6, identified a anchor stud pull ~
out on plate, MK-20-17.
It was also noted that the plate was replaced
with a new plate marked 20-17-2.
In discussing this matter with the
cognizant CB&I representative, the inspector was informed that the
anchor stud pull-out was caused by a lamination in the steel plate, and
therefore, the plate was replaced.
-
During subsequent discussions held with the B&R representatives, the
inspector was informed that the B&R QA/QC staff had-reviewed the item,
and in view of the requirements prescribed by ASTM A-20, B&R did not
consider the matter as an item of nonconformance; however, it was also
revealed that correspondence being generated by B&R and TUSI express a
,
concern regarding the potential of other liner plates having similar
laminations. The use of UT inspection of the liner plate is being
considered.
During the exit meeting the inspector expressed h.is concern
in that the CB&I "Nonconformance Control List" does not provide a clear
basis for the nonconformance, nor is it clear as to the manner in which
B&R identifics, reviews, accepts / rejects and documents items oi non-
conformance identified by subcontractors.
.
The B&R and TUSI representatives stated that this matter would be
reviewed.

'4.
Concrete' Placement
The inspector observed activities related to the placement of approximately
'1200 cubic yards of concrete for CPSES Unit 1 containment.
The placement,
which was acconplished on September 12, 1975, appeared to be adequately
planned and executed. Included within the scope'of activities observed,
'
the inspecto'; reviewed the corrective measures initiated by B&R as
i
outlined in the . licensee's lettet of September 5,1975. Within the scope
of the review, there were no it<..ms of noncompliance observed.
5.
R. W. Hunt Temporary' Procedure
R. W. Hunt has issued Temporary Procedure No. HT-513-9, " Tension Tests",
for use on the CPSES project. The inspector was shown documentation of
review and approval of this procedure by the B&R Project QA tbnager but
evidence of approval by the R. W. Hunt QA Manager as described in R. W.
Hunt Procedure W-1000, " Creation, Revision and Control of' Inspection and
Testing Procedures",.could not be found. It was pointed out by the
inspector that the absence of the date of issuance and approval signature
made the status of this procedure questionable. The R. W. Hunt represen-
_
tative stated that corrective measures would be taken.
This matter was
' '
identified as an unresolved item.

Concrete Cylinder Test Analysis
~
.
R. W. Hunt Procedure No. C 1068, " Statistical Method for Evaluating
Cylinder Strength", Rev. O, 3/6/75, prescribes the preparation of reports
'
in accordance with ACI 214-65, " Recommended Practice for Evaluation of
Compression Test Results of Field Concrete." The inspector reviewed
R. W. Hunt report HCP 588, " Statistical Analysis of Concrete Strength -
Iby 1975", which was issued July 2, 1975. The report appeared to have
been prepared in accordance with R. W. Hunt procedures.
Cylinder test
data for containment mat placement in July was available but had not
-
been processed for statistical analysis.
