101Molten-Salt Reactor Experiment — MSRE plant diagram The Molten Salt Reactor Experiment (MSRE) was an experimental molten salt reactor at the Oak Ridge National Laboratory (ORNL) researching this technology through the 1960s; constructed by 1964, it went critical in 1965 and was… …
102Gas porosity — Determining the true porosity of a gas filled formation has always been a problem. While gas is a hydrocarbon, similar to oil, the physical properties of the fluids are very different, making it very hard to correctly quantify the total amount of …
103Facteur de diffusion atomique — En physique, le facteur de diffusion atomique est une mesure de la puissance de diffusion d une onde par un atome. Il dépend de la nature des interactions entre l onde et l objet diffusant, donc de la radiation incidente : en général, il s… …
104Fission product — Fission products are the atomic fragments left after a large nucleus fissions. Typically, a large nucleus like Uranium fissions by splitting into two smaller nuclei, along with a few neutrons and a large release of energy in the form of heat… …
105Détection de neutrons — La détection de neutrons est la détection effective de neutrons entrant dans un détecteur. Il existe deux aspects de la détection effective de neutrons : l aspect matériel (hardware) et l aspect logiciel (software). Le matériel de détection… …
106Elastic collision — [ black body radiation (not shown) doesn’t escape a system, atoms in thermal agitation undergo essentially elastic collisions. On average, two atoms rebound from each other with the same kinetic energy as before a collision. Here, room… …
107Fermium — Not to be confused with Ferrum , the Latin name for Iron. einsteinium ← fermium → mendelevium …
108Prompt critical — In nuclear engineering, an assembly is prompt critical if for each nuclear fission event, one or more of the immediate or prompt neutrons released causes an additional fission event. This causes a rapidly exponential increase in the number of… …
109Cargo scanning — Intermodal Shipping Containers Cargo scanning or non intrusive inspection (NII) refers to non destructive methods of inspecting and identifying goods in transportation systems. It is often used for scanning of intermodal freight …
110Induced radioactivity — is when a previously stable material has been made radioactive by exposure to specific radiation. Most radioactivity does not induce other material to become radioactive. Neutron activation is the main form of induced radioactivity, which happens …
