Engineering analyzed four con- i yl crete block walla located north and ccuth of North and South Icolation i T.O [ Valve Econc, recpectively, in both Reactor Buildinga. Analysis of the j TI-] l ceicnic capabilities of the cubject walls indicated that using procent l j7] [ day calculational methoda the cafety factorc of the concrete expansion  !
