World Bank, IAEA partner to fund nuclear energy
The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

The diffusion processes of neutrons in Lucite have been investigated. The mechanisms for these processes have been described as having two steps. In the first step, the fast neutrons collide with the nuclei of Lucite, losing energy until they reach thermal energies. In the second step of the diffusion process, the thermal neutrons continue to diffuse through the Lucite without any significant loss of energy until they are finally absorbed or leak out of the system. Experiments were performed to study these two processes and to estimate the absorption cross section in Lucite. The experiments yielded an average range of 6.3 ± 0.1 cm for fast neutrons slowing down to thermal energies and a thermal absorption cross section in Lucite of 0.52 ± 0.02 b.
