INFRACTION Condition Reported:
As required by Criterion V of Appendix B to 10 CFR 50, 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-6, "Concrete" requires curing of concrete test cylinders to be in accordance with ASTM C192.
ASTM C192 requires concrete cylinder to be stored in a moist room meeting the requirements'f ASTM C511.
ASTM C511 requires that moisture in the curing room atmosphere be saturated to the degree needed to ensure that the exposed snrfaces of all cylinders in storage will both look moist and feel moist at all times.
Contrary to the above, on January 4, the surface of cylinder numbers 4818 through 4849 and cylinder numbers 4707 through 4757 stored in the concrete laboratory curing room were dry.
I Corrective Steps Taken and Results Achieved:
zs effective zn mazntal.ning the cylinders zn a moist c
Corrective Ste s Taken to Avoid Further Noncompliance:
The nonconforming condition and the affected concrete cylinders listed in the Notice of Violation were reported in Deficiency and Disposition Report No. 356 for purposes of control and resolution.
It is noted that the relative humidity of the curing room has not dropped below the specified value.
An oscillating sprinkler connected to a continuous water supply has been placed in the curing room to augment the installed system.
This combination, while not economical, ondition.
Materials for a larger, more reliable spray system have been placed on order.
This system will contain twelve spray nozzels which will provide overlap and improved reliability.
The temporary system will be used to augment the present system until the new system is operational.
Date When Full Compliance Will be Achieved:
It is anticipated that the new spray system will be operational by April 1, 1980.
