Evaluation of the Uncertainties of the Temperature in the Channels of Liquid Metal Cooled Reactors. | [SULLA VALUTAZIONE DELLE INCERTEZZE DELLE TEMPERATURE IN CANALI DI REATTORI RAFFREDDATI CON METALLI LIQUIDI.]
No full textThe paper deals with the principal factors influencing the variations from nominal values of measured variables (such as coolant and fuel temperatures) in the control system of a nuclear reactor core. The possibility of a control system based upon the measurement of coolant outlet temperatures from reactor channels is examined and some computations of variations from nominal values are also presented in case of Liquid Metal Breeder Reactors

New dosing system: the intelligent screw feed
No full textOne of the main problems in almost all industrial processes handling molten metal is the accurate dosing of powder metal. This is particularly crucial in the pharmaceutical and food industries. The article looks at a new dosing system using an innovative new screw feed, analysing the results of tests carried out in the WAM Spa laboratories. The screw feed doser was developed to respond to the growing demand for an accurate dosing system as an alternative to the conventional weighing conveyor belts. Screw feeders are known for their simple construction and reliability. Originally developed for use in the food industry they have gone on to find application in a wide range of industries. The screw feed is a closed system capable of handling volatile material. Another important advantage is that it is as economical and as efficient as weighing belts. The screw feed system consists of a screw feed, weigh bridge and automatic checking and regulating system. The tests carried out produced satisfactory results, showing this system to be efficient and reliable. This system can certainly be used instead of a weighing belt in many applications, although in others the weighing conveyor belt cannot be replaced. Future developments in the screw feed system look very interesting although there is still a long way to go in terms of realising its full potential
