ABSTRACT:
A weighing system for obtaining the mass of objects, particularly spent nuclear fuel rods, includes a weighing device having a weighing platform on which objects to be weighed are placed. The platform rests on three hydraulic load cells, each communicating with an associated pressure transducer. Electrical signals from the transducers representing the pressure in the load cells and, consequently, the mass of the objects, are converted into digital form by a convertor and then processed by a computer to calculate the required mass values. The weighing device is located within a radioactive environment existing in a shielded enclosure, the transducer and the signal processing means being situated outside the enclosure and remote from the radioactive environment.
