Restatement of Unresolved Item: -It was found that several masonry-walls in the Reactor Building ! and the Emergency Cooling Tower had what appeared to be through
cracks at the boundary interface with reinforced concrete walls. 3 The licensee's construction detail drawing (6280-S-246, Rev. 5) d specified concrete expansion anchor bolts to provide a. positive d connection at this type of boundary. The inspector was unable to
confirm the existence of positive connections through visual j h observations or from the licensee's QC documentation. All of the l L noted crack locations were at wall boundaries where simply { supported boundary conditions utilizing positive connections had I been assumed in the reevaluation calculations.
