The application of petroleum products as moderator-coolants in marine propulsion reactors is examined. The organic moderated nuclear reactor appears attractive for maritime propulsion because it offers the advantages of low capital costs and low maintenance and operating charges. The feasibility of using an organic fluid for neutron moderation and reactor heat transfer has been demonstrated and would be even more favorable with increased cost reductions. This could be achieved by using petroleum fractions as moderator coolants in place of the terphenyl mixture currently employed. Data suggests that petroleum fractions composed principally of condensed ring aromatic compounds should approach the terphenyls in radiation and thermal stability. An improved purification technique may also result in lower coolant replacement cost through reduction in the amount of material discarded as residue.
