    摘要: An articulated lance for cleaning sludge located between steam generator tubes is disclosed. A plurality of radius blocks are attached to the end of manipulator member and are actuatable by a cam assembly to form an arc permitting the lance to be received between adjacent tubes within a tube bundle. A plurality of fluid passageways interconnect a fluid inlet on the manipulator member with one or more outlet orifices adjacent the end of the lance. The outlet orifices are positioned outwardly with respect to the end of the manipulator member so that fluid passing therethrough can be directed to impinge upon sludge surrounding the tubes. A spring backing place biases the radius blocks and the manipulator member back into the same plane upon deactuation of the cam assembly.

    摘要: A heat transfer system and method for controlling heat transfer to and from a container having thermal insulation disposed with respect to said container or compartment so as to inhibit the flow of heat into and/or out of the compartment, said insulation comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a haloalkene according to Formula IA: where each R is independently Cl, F, H, or CF3, provided that the total number of carbon atoms is either 3 or 4, R′ is (CR2)nY, Y is CF3 and n is 0 or 1; and a heat transfer system for adding and/or removing heat from the compartment or container by use of a heat transfer fluid comprising a haloalkene Formula IB: where each R is independently Cl, F or H R′ is (CR2)nY, Y is CF3 and n is 0 or 1.
