In order to reduce the response time when simulating large reactors in detail, a parallel version of the
thermal–hydraulic subchannel code COBRA-TF (CTF) has been developed using the standard Message
Passing Interface (MPI). The parallelization is oriented to reactor cells, so it is best suited for models consisting
of many cells. The generation of the Jacobian matrix is parallelized, in such a way that each processor
is in charge of generating the data associated with a subset of cells. Also, the solution of the linear
system of equations is done in parallel, using the PETSc toolkit. With the goal of creating a powerful tool
to simulate the reactor core behavior during asymmetrical transients, the 3D neutron diffusion code
PARCSv2.7 (PARCS) has been coupled with the parallel version of CTF (pCTF) using the Parallel Virtual
Machine (PVM) technology. In order to validate the correctness of the parallel coupled code, a control
rod drop transient has been simulated comparing the results with the real experimental measures
acquired during an NPP real test.
