Inspection on April 25-27, 1979
Areas Inspected
This routine, unannounced inspection involved 21 inspector-hours onsite in
the areas of concrete placement, preventive maintenance, and reactor cavity
liner plate welding (Unit 2).
Results
Of the three areas inspected, no apparent items of noncompliance or devia-
tions were identified in one area; one apparent item of concompliance was
found in one area (Infraction - Electrical Preventive Maintenance - Details
paragraph 5.b.) one apparent deviation was found in one area (Concrete Design
Commitments - Details paragraph 5.a).

Independent Inspection Effort
a.
Observation of Concrete Placement (Units I and 2)
The inspector observed placement of Category I concrete pour
1-01D-]08B in Unit 1 tendon gallery wall.
Acceptance criteria
examined by the inspector appear in the following documents:
(1) Section 3.8 of the Vogtle PSAR
(2) GPC Construction Procedure CD-T-02, Concrete Quality Control
(3) Bechtel Specification X2AP01, Section 3.6, Material Testing
Se rvices
Forms were tight and clean and preplacement inspection was
indicated by the signed pour card. Areas inspected included
delivery, testing, conveying, placement and consolidation of
concrete.
The following concrete records were reviewed:
(1) Concrete Pour Card (Form CD-T-02-36)
(2) Batch Record Summary (Form CD-T-02-37)
(3) Summary of Concrete Placed (Form CD-T-02-39)
Concrete operations were continuously monitored by civil QC
personnel.
Concrete placement, testing and inspection were
conducted in accordance with applicable procedures.
The inspector noted that the pour card and applicable civil drawing
specified a 521(D-2) mix.
Bechtel Specification X2AP01, Division
C3, Section 3.6 describes the D-2 mix in Table II as a concrete mix
containing flyash designed for a strength of 5000 psi at 91-days.
Note 4 to T.ible II states that the design strength for all 5000 psi
and 6000 psi concrete is at 91-days. Discussions with site personnel
indicated all of the Category I concrete in the containment and

(4) Specification X3AR01, Section E2, Station Service Equipment
The IE inspector reviewed maintenance records for various safety
related heat exchangers, valves and pumps in storage on site.
Preventive maintenance on these mechanical components had been
performed at the specified intervals in accordance with applicable
procedures.
The preventive maintenance records for the fellowing safety-related
electrical components were reviewed:
