    Leak rate specimens for Phase 2 will represent elements with penetrations located in the containment cylinder wall. Such a wall element is shown in fig. 14.Specimens will be 3.5-ft (1.1-m) thick and will range from 7-ft (2.1-m) to 11-ft (3.4-m) square. Small and medium penetration sleeves of 10 in (254 mm) and 36 in (914 mm) diameter, respectively, will be cast into various specimens.
