Inspection on January 10-12, 1979 Areas Inspected This unannounced inspection involved 23 inspector-hours onsite in the areas of construction status; concrete procedures, specifications and records; batch plant; soils and concrete laboratory; reinforceing steel storage; Unit 2 powerhouse backfill operations; licensee actions on a previously identified item of noncompliance; licensee actions on a previously aentified Construc-
tion Deficiency Report.
Results Of the eight areas inspected, no apparent items of noncompliance or deviations were identified in seven areas; one apparent item of noncompliance was identi-fied in one area (Infr.ction - failure to calibrate fine aggregate test sieves
- Paragraph 5, Details I).

Exit Interview The inspection scope and findings were summarized on January 12, 1979 with those persons indicated in Paragraph I above.
The licensee acknowledged the item of noncompliance and unresolved item discussed in paragraphs 5 and 6 respectively.
3.
Licensee Action on Previous Inspection Findings (Open) Noncompliance (425/78-09-01):
Improper use of vibrators and in process testing on structural concrete. The inspector reviewed the
licensee's training session report on concrete placement and consolida-tion and discussed location and frequency of in process testing with responsible engineers.
The licensee is revising Procedure CD-9-02
" Concrete Quality" to redefine reference standards and in process testing requirements. This item remains open pending NRC examination of revision to and implementation of procedure requirements.
4.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviations.
An unresolved items identified during this inspection is discussed in Paragraph.

Independent Inspection Effort The inspector examined the following areas:
a.
Overall construction status b.
Batch plant c.
Soils and concrete testing laboratory d.
Concrete reinforcement steel storage area e.
Backfill operations in the Unit 2 powerhouse block Observations of work at the concrete testing laboratory disclosed the following noncompliance.
Procedure CD-T-02, " Concrete Quality" and referenced ASTM Standard C-136 require that sieves used for grain size analysis conform to ASTM Standard E-11.
Discussions with responsible engineers indicated that sieves used for grain size analysis of fine aggregate are not checked for cerlu.; nce to ASTM Standard E-11.
Failure to perform test activitics as requited by documented instruc-tions is contrary to Criterion 1 of Appendin B to 10 CFR 50 and was identified to the licensee as Inf raction 424/79-01-01 and 425/79-01-01.

a.
Certificati( n records for c oncrete inspectors b.
Procedure CD-T-02, " Concrete Quality" c.

d.
Specification X2AP01, "Di riston C3, Concrete" e.
Batch Tickets for pour number 1-0-1D-001 and 1-0-1D-013 f.
Calibration records for concrete batch plant Examination of batch plant calibration records revealed the following unresolved item.
Specification X2AP01, Division 3, paragraph C3.1.5 B3 requires batch plant scales and metering devices be tested every six months.
Documentation verifying testing of admixture metering devices was not available in the document control room during examina-tion of batch plant calibration records. This item was identified to the licensee as Unresolved Item 424/79-01-02 and 425/79-01-0.... -

Improper fabrication of embeds. The licensee reported a potential CDR regarding the fabrication and installation of embeds to RII on November 22, 1978. An interim report addressing the origin and description of the problem was submitted to RII on December 20, 1978. Obscreations and discussions with responsible 7agineers indicated all embeds not set in concrete are being removed and those set in concrete will be load tested. A final report will be submitted to RII in March 1979. This item remains open pending NRC examination of the final report.
