Abstract
Systems, methods, and apparatuses for accommodating thermal expansion in a tool string are disclosed. Exemplary systems include one or more sacrificial members placed between or adjacent elements of the tool string that are expected to expand when subjected to high temperatures. The sacrificial members are configured to destruct upon exposure to a control signal or a critical temperature or load. Destruction of the sacrificial members provides additional clearance for adjacent elements to expand.
