The following records were reviewed by the inspector for pour Al-K4:
(1) Concrete Pour Card (2) Concrete Sample Data Sheet (3) Mixing Plant Report (4) Concrete Curing Report (5) Slump Control Record Concrete operations were continuously monitored by Civil QC personnel.
Concrete delivery, conveying, placement, consolidation and curing were conducted in accordance with applicable procedures.
No items of noncompliance or deviations were identified.
b.
Quality Assurance (QA) Audits (Units 1 and 2)

Investigation Reports (QCIR) and Nonconformance Reports (NCR).
The project inspector will monitor resolution of these audit deficiencies.
This item is identified as inspector followup item 566-567/79-16-01, Resolution of Site QA Audit YC-G-79-16 Deficiencies.
No items of noncompliance or deviations were identified.
c.
Work Package System (Units 1 and 2)
The project inspector reviewed the work package system as implemented on site. The following procedures are applicable:
S0P 11 Preparation, Review, Issue, Execution, and Closure of Work Packages CEP 5.04 R3 Work Packages These procedures were reviewed by the project inspector.
S0P 11 augments and clarifies the guidance given in CEP 5.04.
Areas inspected included preparation of work packages, review by applicable QC/ Project personnel, identification and documentation of QC hold points, identification of applicable drawings and procedures, control of revisions and addendums, and closure of work packages.
The following closed work packages were reviewed:
D013-E-1 D010-M-5 D005-C-FF77
.
.
D006-C-1 D010-M-6
.
Open work package D440-M-2 was also reviewed. This work package covers fabrication and installation of three-quarter nch ASME Class 3 chill water piping. Welding of this piping was previously inspected and reported in IE inspection report 566-567/79-10. Documentation of all required QC hold points was on file in the Document Control Unit.
Hydrostatic testing had been completed and documented, but a noncon-formance report (NCR) was in preparation to identify and resolve the application of incorrect test pressures to portions of the chill water piping.
Preparation, review, issue, execution and final closure of work packages inspected was in accordance with applicable procedures.
No items of noncompliance or deviations were identified.
