Laboratory studies indicate that a lithium-filled annular heat pipe Is feasible as a means of obtaining near isothermal conditions axially along the surface on the cladding of a short fuel sample in an in-pile fuel-irradiation capsule. At a 1500 C operating temperature the axial spread of temperatures was less than 20 C along a three inch length In an experiment simulating the irradiation capsule. The annular heat pipe would be Incorporated Into the current capsule configuration employed in the high-temperature-fuels program to achieve uniform specimen cladding temperatures of 1600 to 1900 C.
