Heads will be fabricated to ASME Section III, 1974 Edition through the 1974 Winter Addenda using single V groove welds without backing rings. The nozzle flued head and expansion joint materials and pip. cizes are listed in the attached Table 1. The joints are considered Nuclear Class II and radiography will be performed.
