abstract={
The dynamic space- and frequency dependent response of a Molten Salt
Reactor (MSR) to stationary perturbations is investigated in a
simple analytical model. The Green's function of the system is
investigated in the general case of arbitrary fuel recirculation
velocity and in the limiting case of infinite fuel velocity which
permits closed form solutions both in the static and dynamic case.
It is found that the amplitude of the induced noise is generally
higher and the domain of the point kinetic behaviour valid up to
higher frequencies than in a corresponding traditional system. This
is due to the differing behaviour of the delayed neutron precursors
as compared to the traditional case. The MSR equations are not
self-adjoint and the adjoint equation and adjoint function have to
be constructed, which is also done here. Finally the space-dependent
neutron noise, induced by propagating perturbations of the
absorption cross section is calculated. A number of interesting
properties that are relevant to full size MSRs are found and
interpreted. The results are consistent with those in traditional
systems but the domains of various behaviour regimes (point kinetic,
space dependent etc.) are shifted to higher frequencies or system
sizes.},
