29 SSM The uranium ore mined today contains only 0.72% of fissionable 235U, too little to make reactor fuel for thermal-neutron fission. For this reason, the mined ore must be enriched with 235U. Both 23U (Tu2 = 7.0 x 10° y) and 238U (T12 = 4.5 x 10° y) are ra- dioactive. How far back in time would natural uranium ore have been a practical reactor fuel, with a 23$U/23$U ratio of 3.0%?

In class I derived the ordinary nuclear density to be about 0.138 u/fm3. A neutron star is a collapsed star that contains neutrons in a highly compactified state, so its average density is higher. Assume a neutron star is spherical and has an average density which is about twice the ordinary nuclear density. If it is 50% heavier than the Sun, what would be its radius?
