Cylindrical amount split mold adiabatic radiation shielding device

摘要

PROBLEM TO BE SOLVED: To provide a split cylinder type heat insulating radiation shielding device in which shielding material can be removably built in a short time without lowering heat insulating performance and radiation shielding performance. ;SOLUTION: In a split cylinder type heat insulating device with semicircular shielding material B made of lead, disposed at a laminated intermediate part of heat insulating material 2 charged in a cylindrical metal case body A, an inner surface plate a₁, an outer surface plate a₂ and end face plates a₃ formed of low heat conductive steel plates are connected by L-shape fittings C₁, C₃, and the contact part of the shielding material B with the end face plates a₃ are held between L-shape holding fittings C₂, C₄ connected to the L-shape fittings C₁, C₃. The shielding material can therefore be built in removably in a short time without lowering heat insulating performance and radiating performance.;COPYRIGHT: (C)1999,JPO
