Benchmarking the coarse mesh radiation transport (COMET) method

This thesis presents a whole-core benchmark of the European Pressurized Reactor
(EPR) using multiple transport methods. The core specifications were taken directly from
the Final Safety Analysis Report (FSAR) submitted to the Nuclear Regulatory
Commission (NRC) and the reactor was modeled in a stylized manner while maintaining
full heterogeneity at the pin and assembly level. The geometry and material specifications
are given as well as problem-specific cross sections for 2, 4, and 8 energy group
calculations. Cross sections were generated using HELIOS, a lattice depletion code based
on the Collision Probability Method (CPM). The multi-group cross sections were utilized
in the reference calculation, COMET calculation, and response function generation. The
reference solution was obtained via an MCNP model identical to the one implemented in
COMET. Specific steps towards constructing and running a COMET calculation are
outlined. Detailed results including assembly eigenvalues, core eigenvalues, and pin
fission densities are presented.
