Under a prolong time neutron irradiation of 232Th by a strong constant neutron flux

a part of 232Th atoms will be converted into a series other nuclides as a result of successive neutron interaction. These neutron born daughter nuclides of 232Th consist of fissile nuclides such as 233U

235U

239Pu

241Pu

… and fertile nuclides

such as 233Pa

234U

236U

237Np

238Pu etc. As a rule the concentration of each daughter nuclide starts from zero and then increases gradually as the irradiation proceeds until reaching a saturated value and then decreases at a similar rate as the decreasing rate of 232Th. A reactor fueled with thorium and its whole family of neutron born daughter nuclides

with each daughter nuclide at its own saturated concentration

may possess some interesting properties. A preliminary study of the feasibility of such constellation type fissile fuels reactor is presented.
