1. An electric submersible pump (ESP) assembly comprising:
an electric submersible motor between a thrust chamber and a motor expansion chamber, the motor expansion chamber comprising:
a bellows coupled to a releasable bellows anti-movement system, the releasable bellows anti-movement system comprising a heat-activated release and alterable between:
an immobilizing position, wherein the releasable anti-movement system prevents concertinaed movement of the bellows in the immobilizing position, and
a released position, wherein the bellows is concertinaedly moveable in the released position; and
wherein the releasable bellows anti-movement system is in the immobilizing position below a release temperature and in the released position above the release temperature.
