Time-dependent deterministic transport on parallel architectures using PARTISN

PDF Version Also Available for Download.

Description

In addition to the ability to solve the static transport equation, the authors have also incorporated time dependence into the parallel S{sub N} code PARTISN. Using a semi-implicit scheme, PARTISN is capable of performing time-dependent calculations for both fissioning and pure source driven problems. They have applied this to various types of problems such as shielding and prompt fission experiments. This paper describes the form of the time-dependent equations implemented, their solution strategies in PARTISN including iteration acceleration, and the strategies used for time-step control. Results are presented for a iron-water shielding calculation and a criticality excursion in a uranium ... continued below
