Severity Level V Violation 8 10 CFR 50, Appendix B, Criterion V, as implemented by Carolina Power and Light PSAR Section 1.8.,5.5, requires in part that "Activities affecting quality shall be prescribed by documented instructions procedures or drawings...and shall be accomplished in accordance with these instruc-
- tions, procedures or drawings."
Shearon Harris specification CAR-SH-CH-6 "Concrete" requires that field cured test cylinders be controlled in accordance with ASTM C-31.
ASTM C-31 specifies that field cured test cylinders are to be stored under conditions that maintain the temper ature in a range of 60-80 degrees fahrenheit for the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after molding of the test cylinders.
Contrary to the above, test cylinders from concrete pour numbers 1SX>1241-006 and 007, AC SL305-003 and ICB EF 305-001 were observed being stored at temperatures less than 60 degrees fahrenheit during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after molding.
Denial or Admission and Reasons for Violation:
I The violation is correct as stated.
The reason for the violation was due to field personnel unplugging the curing boxes and testing personnel were not preheating the boxes prior to use.
Corrective Steps Taken and Results Achieved:
The specimens in the unplugged curing boxes were removed and taken to the concrete laboratory curing room, as required.
The boxes that were not pre-
- heated, were up to the required temper ature within 30 minutes after the initial observation..
The concrete cylinders in question were compression tested and the results for each placement met the project specification requirements.
Corrective Steps Taken to Avoid Further Noncompliance:
Construction Inspection personnel are now assisting Quality Assurance personnel to insure curing boxes are at the placement, in working order and are preheated, if required, prior to placing cylinders in them.
Tags stating "Do Not Unplug", have been placed on the curing box electrical plugs to preclude inadvertent unplugging by field personnel.
In addition, new curing boxes have been made that will insure a more effective temperature control.
Date 0/hen Full Compliance >lill Be Achieved:
Full compliance is considered to have been achieved on December 15,
- 1981, with the implementation of tagging curing box electrical plugs and instructions given to inspection and testing personnel.
