! Structural Concrete t

The purpose of the inspection was to determine by direct observation and '

independent evaluations: (1) whether work related to structural cnnerete was accomplished in an acceptable manner; (2) If sufficient licensee QA/QC  !

inspections were performed and documented to verify quality of work; (3) i if the system for preparing, reviewing, and: maintaining records was func- i tioning properly; and, (4) if management controls were effective. The }

inspector reviewed documentation and held discussions with cognizant '

licensee personnel to assess the adequacy of the above mentioned attribute Records reviewed during this inspection are listed in Attachment Based on the above review, discussions, and independent evaluation, the I inspector determined that:

• records confirm that concrete production and placement and }

installation of components conformed to project procedures and  !

specifications;

• adequate QA/QC inspections were performed using appropriate  ;

acceptance criteria, i

!

• results of compression test quantitatively confirms acceptability ,

of concrete and curing conditions; and, ,

• construction deficiencies were properly documented and dispositione There was one specific question regarding substitution of No. 8 rebars j with No. 9 rebars. The acceptability of this substitution was ne. clearly -

documented. The licensee has dispositioned a Supplier Deviation Disposi-tion Report (SDDR No. 1) accepting the supplier's recommendation for this (

substitution. There was, however, no documented calculation to justify the acceptability of this change. At the inspector's request, calcula-  !

tions were performed and provided to the inspector to clearly document and >

justify the substitution. Also, the stability of the Emergency Diesel  !'

Generator building due to tunnelling was reviewed. The inspector determined that adequate evaluation had been performed, and protection provided to  :

preclude any unanticipated problems in this are '

No violation or deviation was identifie . Structural Steel

The inspector reviewed documentation, held discussions with cognizant licensee engineers, and visually examined completed work to ascertain the l adequacy of construction and erection proct:res for structural steel '

. 4 framings and supports, conformance of materials to specifications and codes, and the adequacy of inspection of bolted connectionc. The inspector also compared the "as-built" configuration of framing with the design drawings, and Bechtel's Work Plan and Inspection Record (WPIR).

Based on the above examinations, discussions, and inspection records, the inspector determined that:

+ the materials and erection process for structural steel conformed to the applicable codes and specifications;

• adequate licensee QA/QC inspections were performed to verify the conformity of work with defined acceptance criteria;

• Certified Material Test Reports (CMTR), with quantitative results, wert available to verify the quality of material, and qualified welding and NDE procedures were available for use; and,

• nonconformances were properly dispositioned and the nonconformance reports clesrly identified the status of nonconforming item No violations or deviations were identifie .0 Exit Interview At the conclusion of the inspection, the inspector met with the licensee representatives (identified by * in paragraph 1), where the inspector summarized the purpose, scope, and findings of this inspection. T.b e inspector did not provide any written material to the licensee dO ing this inspectio The licensee did not indi; ate that any proprietary material was included within the scope of this inspectio __-_-___-_-___ _ _ __
