A device for retaining and supporting pipes having a central curved section between two linear ends and being open to receive one or more pipes therein and serving to protect the pipe from being kinked or bent during construction and post-construction activities. The sides or arms of the device may be extended and bendable such that a pipe may be inserted between the arms and therefore held in place by a spring force. The device may be attached to wall studs or other structures through the use of plumbing straps, which can be weaved through slots in the device to securely hold the pipe(s) in place.

Pipe, tubing and conduit support and retainer

A method of replacing a boiling water reactor core shroud includes the steps of removing at least a portion of the existing core shroud from supporting structure in the reactor vessel, lowering a replacement shroud into the reactor vessel, positioning the replacement shroud on the supporting structure such that a bottom portion of the replacement shroud mates cooperatively with the supporting structure to limit lateral movement of the replacement shroud relative to the reactor vessel, and holding the replacement shroud assembly in place by applying axially compressive forces to the shroud in the direction of the supporting structure. If the existing core shroud is secured by welds, a parting cut is made to remove the shroud and the replacement shroud is held in place by securing a plurality of tie rods between sites on the replacement shroud and the supporting structure at a respective plurality of angularly spaced locations about the shroud periphery. Existing safe end assemblies welded to core spray supply piping in the reactor vessel are removed and replaced with new safe end assemblies carrying components which mechanically couple with core spray supply piping carried by the replacement core shroud.
