Abstract [en]

A Monte Carlo simulation of the ELECTRA reactor using (U,Zr)N fuel and a liquid lithium coolant is performed using the Serpent simulation code. The results show a reactor with a total reactivity coefficient of the coolant, fuel and material expansion that is strongly negative. These properties make the ELECTRA reactor a good candidate for a safe space reactor that could be used for propulsion of manned and unmanned space vehicles to Mars and other parts of our solar system.

Abstract [sv]

En Monte Carlo-simulering av ELECTRA-reaktorn med (U,Zr)N som bränsle och flytande Litium som kylmedel utförs med simuleringskoden Serpent. Resultaten visar en reaktor med en starkt negativ total reaktivitetskoefficient för kylmedel, bränsle och materialutvidgning. Dessa egenskaper gör ELECTRA-reaktorn till en bra kandidat för en säker rymdreaktor avsedd för drift av bemannade och obemannade farkoster till Mars och andra delar av solsystemet.
