摘要：

A new core solver named PARAFISH is presented for the solution of large neutron transport core calculations The second order even parity form of the time-independent Boltzmann transport equation is solved using an innovative algebraic domain decomposition method The spatio angular discretization is performed using non conforming finite elements and spherical harmonic expansions (P-N method) The PARAFISH code allows one processor to handle more than one domain This enables proper evaluations of the spaced up Also this enables to show that the domain-decomposition method not only performs well in parallel calculations but also has an inherent acceleration potential That is it yields acceleration even without increasing the number of processors (C) 2010 Elsevier Ltd All rights reserved
