Nuclear Reactor Calculations

2014
The most fundamental evaluation quantity of the nuclear design calculation is the effective multiplication factor (k eff ) and neutron flux distribution. The excess reactivity, control rod worth, reactivity coefficient, power distribution, etc. are undoubtedly inseparable from the nuclear design calculation. Some quantities among them can be derived by

A Nested FGMRES Method for Parallel Calculation of Nuclear Reactor Transients

Journal of Scientific Computing, 1998
A semi-iterative method based on a nested application of flexible generalized minimum residual (FGMRES) is developed to solve the linear systems resulting from the application of the discretized two-phase hydrodynamics equations to nuclear reactor transient problems.

Some methods for calculation of perturbations in nuclear reactors

Physics of Atomic Nuclei, 2015
Some methods for calculation of local perturbations of neutron fields and reactivity effects accompanying them are considered. Existence, uniqueness, properties and methods for finding solutions to the considered problems are discussed.

Nuclear safety calculations for heatpipe power system reactors

AIP Conference Proceedings, 2002
Misperceptions continue to exist about the safety of space nuclear systems—both with reactors and radioisotope systems. Frequently engineers do not bother to sufficiently explain the risk, because it is obvious to them that the risks are inconsequential and that their time can be spent in more productive ways.
