Subject:
ALLEGED COVER-UP 0F NONCONFORiilNG CONCRETE CONSOLIDATION REPAIR DEFICIENCIES - UPDATE (REF PH0-79-182)
As previously reported it has been alleged that certain repairs of concrete honeycombing (misconsolidation) were in nonconformance with site QA/QC require-ments.
As a result of RIII inspection activitics relative to concrete place-ment and consolidation, the following has occurred:
1.
A management meeting was held at the site on June 26, 1979, and an Immediate Action Letter (IAL) was issued outlining corrective actions that the licensee must take relative to concrete activities.
The principal provi-sion of the IAL was to stop safety related concrete activities until certain corrective actions had been taken.
2.
RIII is currently evaluating the licensee's response to this IAL.
Those provisions relative to the placement of safety related concreb have been resolved to the extent that RIII and the licensee have released the stop work on these concrete activities.
Other provisions of the IAL relative to the licensee's activities are being evaluatec by Region III.
3.
The alleger identified in P.10-79-182 was contacted by RIII, provided transportation from his residence in Texas and participated in RIII investigative activities at the site on July 7, 1979.
His allegations with respect to improper concrete repairs were substantially confirmed.
Investigation into the extent of the licensees and contractors knowledge of these deficient conditions prior to tl'e allegations and investigation is continuing.
On July 7, 1979 and July 9, 1979 three additional aihgations were provided to RIII by the Attorney for a local intervening group (Save The Valley).
Three separate individuals provided these allegations.
All three of these new allegations involve concrete placement and repair of honeycomb conditions.
These matters will be reviewed during Regicn III's ongoing investigation.
