Summary

Unirradiated MSRE fuel salt will contain an appreciable neutron source due to spontaneous fission of the urarium, and ( alpha ,n) reactions of alpha particles from the uranium with the fluorine and beryllium of the salt. The spontaneous fission source in the core (25 ft/sup 3/ of salt) is 10/sup 3/ neutrons/sec or less, mostly from U/sup 238/. The alpha-n source is much larger, giving about 4 x 10/sup 5/ neutrons/sec in the core. Nearly all of this latter source is caused by alpha particles from U /sup 234/. (auth)
