INFRACTION Condition Reported,'s required by Criterion V of Appendix B to 10 CFR 50, and as implemented by Carolina Power and Light PSAR Section 1.8.5.5, "Activities affecting quality shall be prescribed by documented instructions, procedures or drawings and shall be accomplished in accordance with these instructions, procedures or drawings".
Shearon Harris specification CAR-SH-CH-4-,
"Embankments,
- Dams, Dikes and Channels; and Appendix 2E of the PSAR require that moisture content of embankment cores be controlled to within plus or minus 2.
percent of optimum.
Corrective Steps Taken and Results Achieved:
Considerable investigation, testing, and technical discussions between NRR, Ebasco and CP&L were completed during development of corrective action and preventive measures.
Corrective action resulted in removal of all questionable material, revision to placement control procedures, revisions to equipment and methods, and changes to the design specifi-
- cation, Additional laboratory testing completed concurrent with "in place" testing during early core removal phases determined that materials with moisture contents of plus four per cent of optimum would satisfy design requirements.
Corrective Steps Taken to Avoid Further Noncompliance; The following summarizes steps taken to avoid further noncompliance:
1.
Design specifications and site control procedures were revised requiring conservative calibration and corrective factors for rapid moistu> e determination methods to allow for continued construction.
2.
Laboratory testing was completed to justify design changes to moisture content ranges and measuring method tolerances.
3.
Design specifications and site control procedures were revised based on completion of laboratory testing.
4.
All previously placed material was r'emoved and replaced.
I Date When Full Compliance Was Achieved:
Full compliance is considered to have been achieved with the removal of previously placed core material completed on June 10, 1980.
