Licensee Action on Previous Inspection Findings (0 pen) Unresolved Item 50-413/80-24-02 and 50-514/80-20-02):
" Curing Compounds on Construction Joints".
Curing compounds were used on construction joints in apparent conflict with referenced paragraph 12 of ACI 301-72. Responsible design engineers claim that their design methods do not take credit for bond.
Construction joints are now being water cured. Specification CNS-1109.01 is being revised to clarify curing requirements and design calculations for safety related
!
structures are being reviewed. This item remains open pending examination
!
by RII:IE of the design calculations review.
(0 pen) Inspector Followup Item 50-413/80-20-01 and 50-414/80-20-01):
" Internal Pressure on Electrical Penetrations".
The licensee is having difficulty meeting the specified gas pressure requirements of 15 Psi at 72 degrees fahren! Lit.
Discussions with respon-l sible engineers and examination of site memo number ii-1361.00 disclosed that revised gas pressure requirements will be issued oy October 3, 1980.
