A neutron back scattering set-up for analysis of hydrogenous sample materials has been simulated using MCNP5 neutron and photon transport code. The set-up is mainly composed of an Am-Be neutron source of 37.2GBq and a He-3 neutron gas detector which are embedded in polyethylene bloc, the latter acting as a reflector. The modelisation used in the simulation was validated comparing thermal...

Radiotracer techniques have been widely applied in various fields of industry in order to diagnose plant processes during operation. This is possible because radioisotopes can selectively label certain process media and represent their movements. Recently, radioisotopes have been successfully used as tracers in the investigations for clarifiers and digesters in wastewater treatment plants....

In distilation column, the packed column for gas-liquid contacting are used extensively for absorption, stripping and distillation operations. One of principal troubleshooting encountered in the operation packed bed is the coke disposition which is related process condition and structural problems. As the gamma scanning technique is an adequate to define on-line troubleshooting, in the...

The pebble bed modular reactor (PBMR) is a type of 4th generation nuclear reactor. In a pebble bed reactor, nuclear fuel is in the form of spherical pebble and moves slowly inside the core of the reactor under the influence of gravity. A coolant gas moves through the voids formed in between the pebbles and removes fission heat generated from the nuclear fuel. Multiphase Reactors and...
