Licensee Action on Previous Inspection Findings (0 pen) Unresolved Item (50-413/80-24-02 and 50-414/80-20-02):
Curing Compounds on Construction Joints.
Curing compounds were used on con-struction joints in apparent conflict with paragraph twelve of ACI 301.72.
The licensee performed an evaluation of their design methods and confirmed that they did not take credit for bond for transfer of shear at construction joints. The licensee submitted the results of this evaluation to NRC in a letter dated August 24, 1981. The licensee in Revision 18 to specification CNS-1109.00-1, " Specification for Structural Concrete for Buildings," clari-fied and addressed provisions when bond is required in construction joints.
The inspector reviewed specification CNS-1109.00-1.
In their August 24, 1981 letter, the licensee stated that use of curing compounds on construc-tion joints had been discontinued. This item remains open pending review by NRC Region II of the licensee's design calculation and design methods.
