ted pipe ruptures outside containment, Reference 2 includes the area of concern in this position and has been used for those plants for which construction permit applications were tendered before July 1, 1973. Reference 3 specifically emphasizes protection via plant arrangement and layouts utilizing the concept of physical separation to the extent practical and has been used for those plants for which construction permit applications were DRAFT Rev. 2 - April 1996 3.6.2-12 tendered after July 1, 1973, and before July 1, 1975, as specified in Section B.4 of BTP ASBSPLB 3-1. BTP EMEB 3-1 has been used for all construction permit applications, in 42 43 lieu of References 2 and 3, since July 1, 1975, and should be used for future applications.44 VI.
