abstract={This thesis contains two studies of the MSR properties. The first
uses one-group theory and data that correspond to a traditional
uranium fuelled light water reactor to investigate the basis physical
differences that might arise due
solely to the movement of the fuel. The second employs two-group
theory and data corresponding to a thorium-fuelled thermal reactor to
investigate the properties of a more realistic possible realisation of
an MSR system, as well as data corresponding to more traditional
systems for contrast.
For both systems, the Green's functions and the dynamic adjoint functions
are 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 equations and
adjoint functions 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.},

AB This thesis contains two studies of the MSR properties. The first
uses one-group theory and data that correspond to a traditional
uranium fuelled light water reactor to investigate the basis physical
differences that might arise due
solely to the movement of the fuel. The second employs two-group
theory and data corresponding to a thorium-fuelled thermal reactor to
investigate the properties of a more realistic possible realisation of
an MSR system, as well as data corresponding to more traditional
systems for contrast.
For both systems, the Green's functions and the dynamic adjoint functions
are 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 equations and
adjoint functions 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
