This paper presents the extension of a verification method of transient neutron transport solvers earlier developed to the case of Molten Salt Reactor (MSR). This method is based on the extraction of the point-kinetic response of a nuclear reactor excited by a mono-chromatic perturbation and on its subsequent comparison with a closed analytical form. Whereas a closed analytical form exists for systems with fixed fuel, no closed analytical form exists in the case of MSR, as highlighted by many authors. A workaround is nevertheless proposed in this work, thus giving the possibility to use a similar verification method to the case of MSR.
