Daniel Procedures QCP-IV-106 and WP-IV-106 contain appropriate procedures for control of concrete deliveries when air and/or slump tests are not passed.
The KG&E Site QA group has conducted a review of the 1979 placements in order to determine if the revised program is effective and te confirm that " follow loads" are tested. The results of their review, which are documented in KG&E Surveillance Reports S-99 (July 10, 1979) and S-200 (April 2, 1980)
(draft), indicate that reject concrete is be.'ng identified and prevented from being used in safety-related placements.

Spalled Concrete in Reactor Cavity - Potential Construction Deficiency Report (10 CFR 50.5S(e))
Spalled and broken concrete has been identified in the ledge around the reactor cavity.
It was first identified on February 27, 1980, and thought to be caused by the swelling of tne 2" x 4" lumber which was used as a form for a drain collector trench.
Subsequent examination and chipping of the area as specified in DR ISD3411C (March 3, 1980) revealed an area which exceeded that allowed to be repaired by the construction force under Specification C-103.
A Nonconfarmance heport (N"R) was issued on March 10, 1980.
On March 24, 1980, Bechtel requested additional information to be supplied on the deficiency in order to completely disposition the NCR.
This item is considered unresolved and will be further reviewed during a subsequent inspection after receipt of the NCR resolution by Bechtel.

Allegation of Defective Welding On March 3, 1980, Region IV received a telephone call regarding defective welding performed on a "rubstructure ring." The involved welder's name was supplied. Upon investigation of this allegation, the following was determined:
The item involved was a seal ring in the refueling canal, a.
