The High Temperature Lattice Test Reactor (HTLTR) at Richland,
Washington, operates at temperatures up to 1000°C. Its low nuclear
power requires a 384 kilowatt electrical heating system, that is
divided into four circuits, to attain the high temperatures in the
ten-foot cube of moderating graphite. This thesis describes the
design...
A two-dimensional perturbation theory computer code,
PERT-IV, has been developed that will calculate reactivity
coefficients, the delayed neutron fraction, and the neutron
generation time.
The program uses the output flux and adjoint
flux from either a diffusion theory or transport theory program.
A discussion and derivation of the perturbation equation...
COBRA-OSU computer code is a fast running computer code for coupled Kinetic-Thermal Hydraulic Analysis of nuclear reactor cores. This code which is based on the standard version of COBRA-IV[superscript (3)] has two major improved features. First, the COBRA-OSU computer code uses Gaussian elimination method instead of Gauss-Siedel iteration for crossflow...
Reactor refueling is a computationally intensive
problem solving process that requires automation since
significant resources are expended upon the search for
an optimal core loading. Without imposing some
constraints upon the configurations investigated, an
extremely large number of prototype loadings may be
generated without discovery of an improved loading. As...
