A shroud segment (40) that includes a body (42) including a leading edge (44), a trailing edge (46), a first side edge (48), a second side (50), and a pair of opposed lateral sides (52, 54). A first lateral side (52) is configured to interface with a cavity (56) having a cooling fluid, and a second lateral side (54) is oriented toward a hot gas flow path (47). The shroud segment (40) includes a first channel (74) disposed within the body (42) having a first end portion and a second end portion and a second channel (74) disposed within the body (42) having a third end portion and a fourth end portion. The first and second channels (74) are configured to receive the cooling fluid from the cavity (56) to cool the body (42). The first end portion and the fourth end portion each include a hook-shaped portion (78) having a free end (80). 种包括本体(42)的护罩节段(40)，该本体(42)包括：前缘(44)、后缘(46)、第侧缘(48)、第二侧缘(50)，以及对相对的侧向侧(52,54)。第侧向侧(52)构造成与具有冷却流体的腔(56)对接，而第二侧向侧(54)朝热气体流动路径(47)定向。护罩节段(40)包括：设置在本体(42)内的第通道(74)，其具有第端部和第二端部；以及设置在本体(4
