Lambda modes of a nuclear power reactor have interest in reactor physics since they have
been used to develop modal methods and to study BWR reactor instabilities. An h–p …

To simulate the behaviour of a nuclear power reactor it is necessary to be able to integrate
the time-dependent neutron diffusion equation inside the reactor core. Here the spatial …

The mechanical vibrations of fuel assemblies have shown to give high levels of neutron
noise, triggering in some circumstances the necessity to operate nuclear reactors at a …

In the present study, the neutron noise, ie the stationary fluctuation of the neutron flux around
its mean value, is calculated in 2-group forward and adjoint diffusion theory for both …
