COMANC'dE PEAK REVIEW TEAM POPULATION DESCRIPTION Page'I of 1 POPULATION NAME: CONCRETE PLACEMENT PREPARED BY:

u 7 DATE: August 5.,

1985 RESPONSIBLE QA/QC SUPPORT ENGINEER SYSTEM, COMPONENTS, AND STRUCTURES:

This population is comprised of individual concrete placements included in the Gibbs & Hill Design, and as identified by Brown & Root Construction Company. Seismic Category 1 structures are listed in Attachment A, per I

FSAR, Section 3.2.1.1.1.

h.

POPULATION BOUNDARY:

l This population includes all Category 1 concrete construction that have been completed and QC inspection and approved as of 8-1-85.

Concrete placements encompasses walls, slabs, beams, columns, piers, pedestals, pads, and curbs.

The following attributes are participants and become an integral part of l

concrete placement, and as such are included ii'_

Placement of reinforcing steel including cadwelds splices.

Installation of waterstops.

Installation of embedded plates, and structural shapes.

Installation of anchor bolts.

Configuration and size of structural elements.

Placing and curing of concrete.

Compressive strength testing.

Surface inspection: Cored holes, patches, cracks, honeycombing, voids.

This population does not include materials used to batch concrete, the batching operation, shop fabrication and receipt inspection of reinforcing steel, cadweld materials, embedded plates, and anchor bolts.

SPECIFIC INTERFACES:

i Location, configuration and size of formed openings is excluded from this population;theyshouldbeconsideredas3ttributeforthecomponent 4# (W requiring penetration. Location of embedded plates is excluded from the population; the allcwable deviation of an attachment to the plate should be considered as an attribute for the component being supported by the plate (e.g., HVAC, conduit support, etc.) Also excluded are anchors installed after concrete placement. They will be included with the component being supported.
