Licensee Action on Previous Inspection Findings (Closed) Infraction 566/79-04-01: QA Audit Corrective Action. The licensee's letter of Apt il 9,1979 stated that the concrete cylinder curing tank temperature control problem was reaudited on February 26, 1979 and documented as a deficiency. The QC engineering staf f origi-nated Nonconforming Condition Report No. 001 on March 1,1979 for the out of specification temperatures in the curing tank and closed the report on March 21, 1979 with the disposition of use-as is. Thermosta-tically controlled immersion heaters were installed in the curing tank on March 6, 1979 and the entire curing operation was moved to the moist curing room in the concrete laboratory facility on March 15, 1979. The licensee further stated that site quality assurance unit employees had been instructed to carefully evaluate corrective actions that have been taken to prevent recurrence before closing audit defi-ciencies. The IE inspector reviewed the audit report YC-C-79-03, NCR 001, inspected the concrete curing room and associated records, and discussed the causes of this infraction with site project and QA personnel. This item is closed.
(Closed) Unresolved Item 566-567/79-01-01: Concrete Design Requirements.
The licensee issued Revision 3 to Yellow Creek Nuclear Plant Drawing 4RE0417-5R-1 that incorporates a 28-day design strength requirement for Category I concrete that is dependent on shoring for support. The IE inspector examined the following drawings selected at random to ensure they specified a 28-day design strength requirement for Category I concrete dependent on shoring, metal decking or bottom face forms for support: 4WE0557-2W-01 R3 (Waste Management Building) 4CE0302-C2-01 R0 (Control Building) No structural concrete requiring 28-day design strength has been placed at the Yellow Creek site as of April 12, 1979. This item is closed.

Acceptance criteria examined by the inspector are specified in the following documents: (1) Section 3.8 of the PSAR and TVA Topical Report TR-75-1A (2) TVA Specification G-2, " Plain and Reinforced Concrete" (3) QCI C-201, Concrete Placement (4) Construction drawing notes Forms were tight and clean and preplacement inspection was indicated by the signed pour card.
Areas inspected included delivery, conveying, placement and consolidation of concrete.
Concrete operations were continuously monitored by civil QC personnel.
Concrete placement and inspection were conducted in accordance with applicable procedures.
No items of noncompliance or deviations were identified in the above area inspected.
Containment Vessel W1 ding Program (Unit 1) c.
Chicago Bridge and Iron Company (CBI) is the contractor responsible for fabrication of the spherical steel containment vessel.
A facility has been established on-site for automatic welding (EH-14 process) of the carbon steel plates that will form the 2311 010 - .
. . . -4-spherical containment vessel. The Region II inspector examined the CBI site organization and facilities. Fabrication will be monitored by the CBI QA program as described in the CBI QA Manual for ASME Section III Products, Issue 8.

Certified Material Test Reports for weld filler material heat numbers 036057, HT412E7191 and HT422E3371 were examined for compliance with Part C of Section II of the ASME Code. Storage and preserva-tion of welding filler material was inspected.
Carbon steel plates in storage and in fabrication were inspected for identifi-cation to ensure traceability to the applicable heat number. The IE inspector examined the radiac instruments utilized by CBI during radiographic operations. The meters were in calibration and were working properly.
No items of noncompliance or deviations were identified in t: e above areas inspected.
d.
