SPOCK (Space POwer Core Ka) is an upgrade of the MAUS reactor that was conceived to generates, via thermoelectric conversion, 30 kW of electricity for space applications. Apart the power scale up, SPOCK is characterised by a forced circulation of the Na coolant into the core. The thermoelectric conversion will be performed out of core, by heat exchange with the primary coolant. The present paper was mainly dedicated on the development of SPOCK general concept and to the preliminary computer modelling for the set up of a calculation chain based on Monte Carlo (MCNPX 2.5.0) code and a thermal hydraulic code (FLUENT 6.2.16). Early results were focussed to a critical revision of the nuclear data to be used in Monte Carlo estimations of the system neutronic performance in the challenging condition of a space mission. The very encouraging results, allows to discuss the future development lines of the SPOCK system and the creation of integrated design tool.

Abstract
SPOCK (Space POwer Core Ka) is an upgrade of the MAUS reactor that was conceived to generates, via thermoelectric conversion, 30 kW of electricity for space applications. Apart the power scale up, SPOCK is characterised by a forced circulation of the Na coolant into the core. The thermoelectric conversion will be performed out of core, by heat exchange with the primary coolant. The present paper was mainly dedicated on the development of SPOCK general concept and to the preliminary computer modelling for the set up of a calculation chain based on Monte Carlo (MCNPX 2.5.0) code and a thermal hydraulic code (FLUENT 6.2.16). Early results were focussed to a critical revision of the nuclear data to be used in Monte Carlo estimations of the system neutronic performance in the challenging condition of a space mission. The very encouraging results, allows to discuss the future development lines of the SPOCK system and the creation of integrated design tool.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
