Core spray upper T-box clamp

A T-box clamp apparatus (36) which applies compressive forces to a T-box (26) in a boiling water nuclear reactor pressure vessel (10) is described. The T-box clamp apparatus (36) clamps to the T-box (26) and distribution header pipes (18, 20) to hold the distribution headers in place and in contact...

Zusammenfassung:	A T-box clamp apparatus (36) which applies compressive forces to a T-box (26) in a boiling water nuclear reactor pressure vessel (10) is described. The T-box clamp apparatus (36) clamps to the T-box (26) and distribution header pipes (18, 20) to hold the distribution headers in place and in contact with the T-box (26). The T-box clamp apparatus (36) includes a first and a second of clamp assembly (38, 40) and a clamp strong-back assembly (42) coupled to the first and second clamp assemblies (38, 40). Each clamp assembly (38, 40) includes upper and lower clamp bodies (44, 46) that are coupled to a distribution header pipe (18, 20). The strong-back assembly (42) includes an upper (76) and a lower (78) strong-back body configured to engage the T-box (26), with the upper strong-back body (76) coupled to the upper clamp bodies (44) of the first and second clamp assemblies, and the lower strong-back body (78) is coupled to the lower clamp bodies (46) of the first and second clamp assemblies (38, 40).
