Gentlemen:
This refers to the telephone conversation between you and Mr. W. C. Seidle of
this office on November 5, 1979, concerning irregularities in qualification
testing of concrete ingredients by the Southwestern Laboratory facilities at
Fort Worth, Texas, for the River Bend Station.
With regard to the matters discussed, we understand that you plan to immediately
halt further placement of concrete in safety-related structures until you have:
Conducted an engineering analysis of safety-related concrete that has been
a.
previously placed.
b.
Conducted a complete review of safety-related con : rete materials and con-
ducted testing in order to determine: (1) acceptability of cement; (2)
the potential for alkali reactivity of aggregates (fine and coarse); and
(3) acceptability of primary and standby water and ice sources.
c.
Conducted a review of mix design qualifications to ascertain that all
requirements have been met.
d.
Reviewed the adequacy of your Quality Assurance program for verifying satis-
f actory quality of safety-related materials and services with particular
emphasis on those programs provided by subcontractors.
Conducted an audit of Delta Testing and Inspection, Inc., and Pittsburgh
c.
Testing Laboratories (PTL) to verify implementation of their QA programs.
f.
Provided written information to Region IV on your findings and described
those measures considered necessary for the correction of the matters
discussed above. Also, until you have provided for review of informa-
tion verifying that corrective measures have been properly implemented,
prior to resuming the placement of concrete in safety-related structures.
