Background: Hot lab is a specially designed room in a nuclear medicine hospital where the radiopharmaceuticals are delivered, stored and prepared for dispensing. 99Mo/99mTc-generator is the major source in the hot lab used for various medical imaging. It is important to maintain a standard for hot lab procedures to optimize the patient care and minimize radiation exposure to all nuclear medicin...

Research on achieving Class A material through thermophilic digestion at 55 C (131 F) in a continuously fed, single reactor configuration was performed at the Districts= Joint Water Pollution Control Plant (JWPCP) in Carson. Bench-scale (8.0 l) work showed that sufficient thermophilies for seeding purposes exist in mesophilic cultures at 35 C (96 F). After stable bench-scale thermophilic operat...

The CFD code GASFLOW solves the time-dependent compressible Navier-Stokes Equations with multiple gas species. GASFLOW was developed for non nuclear and nuclear application. The major nuclear applications of GASFLOW are 3D analyses of steam/hydrogen distributions in complex PWR containment buildings to simulate scenarios of beyond design basis accidents. Validation of GASFLOW has been a continu...

In order to improve the operation performance of nuclear power plants, this paper introduces a modeling method unplanned automatic shutdown units based on Fault Tree Analysis, and takes signal steam generator water level low-low as an example, analyzes development process application scenarios fault tree in detail. The results show that solves huge complex problems model units, can be used comp...

The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...

In this study, a nuclear hybrid energy system (NHES) with large-scale hydrogen storage integrated gas turbine cycle is proposed as flexible for load following. The consists of reactor, steam Rankine cycle, electrolyzer, in an underground salt cavern, and Brayton that uses fuel to generate additional electricity meet peak demand. A dynamic mathematical model developed each subsystem the NHES. To...

A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting sulphur and sodium are recovered from the black liquor, the recovery boiler then serving a...
