| Abstract: | Physical experiments and numerical calculation of point source are important for studying reactor shielding and radiation effect, and for investigating the neutron parameters and computaional methods. In this paper, several typical physical experiments about point source of 14 MeV neutron have been calculated by the two-dimensional discontinuous finite element procedure. The calculated results are compared with the experimental resuts. The agrecement is satisfactory. |
