Answer #1

The neutron flux that can be define as the number of neutrons crossing through some arbitrary cross-sectional unit area in all direction per unit time. Since it is a scalar quantity, therefore it is also known as the scalar flux. The formula used to find scalar flux is

where,

   - scalar flux or neutron flux (neutron.cm-2.s-1)  

- neutron density (neutron.cm-3)

- neutron velocity (cm.s-1)

M. The thermal neutron density is 108 neutrons/cm3 in a 1 meter diameter spherical reactor. Assume that the reactor is made entirely of U-233 having a density of 19.0 g/cm3. Also assume that the neutron speed is a uniform 2200 m/s. Find the neutron flux, the total reaction rate for fissions, and the (approximate) power produced by the reactor.
