Ghana’s highly enriched uranium (90.2%) research reactor has been converted to a low (13.0%) type. Its neutron parameters have characterized for the application of k0-instrumental activation analysis. The magnitude LEU epithermal shaping factor (?) at irradiation site increased by about 25% as compared HEU, while thermal neutrons decreased 5%. This indicates that spectrum is much dependent on 1...

The International Atomic Energy Agency (IAEA) requires that all test and research reactors operating on Higher Enriched Uranium (HEU) should be converted to Low (LEU) for safety security purposes. Nigeria having a Miniature Neutron Source Reactor (MNSR) has been long interested in fuel technological not just develop the area but also meet with resolution nuclear treaty set out by global regulat...

A novel means of combined spectroscopic and radiographic zero-knowledge warhead verification has been developed and investigated using Monte Carlo simulations. This verification approach, henceforth called "epi-ZK," uses timestructured beams of epithermal neutrons to verify weapon isotopics and geometry without creating or transmitting meaningful information about the device design. This method...

Please cite this article in press as: Voigt-Heu unfamiliar individuals, Animal Behaviour (2 Bats use echolocation for orientation during foraging and navigation. However, it has been suggested that echolocation calls may also have a communicative function, for instance between roost members. In principle, this seems possible because echolocation calls are species specific and known to differ be...
