' !ura to sample concrete test-cylinders.
The inspector examined une iicensee's response dated March 3, 1981 and implementation of the response. A new method has been established to track sampling and testing of concrete. This item is closed.
(Closed) Inspector Followup Item (424/79-13-01 and 425/79-13-02): Retriev-ability of QC records.
Examination of records on concrete pour number 2-01C-001, -002, -004 demonstrated that the licensee has updated their -
records storage systems.
Records requested by the NRC inspector were
,
retrieved in a timely manner. This item is closed.

Containment (Structural Concrete II)
Observation of Work and Work
-
Activities, Unit 1)
The inspector observed partial placement of pour numbers A-088-049 in the auxiliary building and A-118-067C in the control building.
Acceptance criteria examined by the inspector appear in the following documents:
a.
specification X2AP01; Forming, Placing, Finishing and Curing Concrete b.
Procedure CD-T-02, Concrete Quality Control c.
PSAR, Sections 3 and 17 Forms were tight and clean, rebar was properly installed and clean.
Preplacement inspection was indicated by the signed preinspection form.
Activities were continuously monitored by QC personnel. Examination of the batch plant indicated proper mixes were being delivered to specified sites, materials were being controlled and accurate batch plant records were being generated.
Samples for temperature, slump, air content, unit weight end strength met frequency requirements.
Observation ~ of placement activities disclosed the following violation.
Procedure CD-T-02, " Concrete Quality Control", paragraph V1.E.7 requires the spacing of concrete vibrator insertions to be approximately 18 inches apart.
In the lower one-third (approximately 10 feet) of pour number A-08B-049, vibrator insertions were made through openings spaced three-five feet apart
'.
-
in the concrete forms. The size of the openings, one foot wall width, and congestion did not allow the spacing of concrete vibration insertions to be made at the specified 18-inch spacing. Also most of the vibration was being
done with pencil vibrators. The specified 18-inch spacing is not adequate for pencil vibrators.
Failure to control concrete vibration in accordance with requirements was identified to the licensee as violation number 50-424/81-06-01.
