The purpose of this paper is to present new analytical derivations to describe the emission and detection statistics of neutrons and photons generated in and emitted from fissile samples, with absorption included. The results of the analytical approach are compared with and validated by corresponding Monte Carlo simulations. The joint statistics of the generated and detected neutrons and photon...
Our previous studies on water cooled thorium breeder reactor based on matured pressurized water reactor (PWR) plant technology concluded that reduced moderated core by arranging fuel pins in a triangular tight lattice array and using heavy water as coolant is appropriate for achieving better breeding performance and higher burn-up simultaneously [1–6]. One optimum core that produces 3.5 GW ther...
A series of measurements of neutron induced fission cross section of various TRU isotopes have been performed at the CERN n TOF spallation neutron facility, in the energy range from thermal to nearly 250MeV. The experimental apparatus consists in a fast ionization chamber (FIC), used as a fission fragment detector with a high efficiency. Good discrimination between alphas and fission fragments ...
Multidimensional gamma-spectrometry is a potential solution for safeguarding future thorium-fuelled molten salt reactors (MSRs). A high-sensitivity system developed at Pacific Northwest National Laboratory (PNNL), the Advanced Radionuclide Gamma spectrometer (ARGO), has demonstrated direct 233 U assay in freshly irradiated fuel samples using dual-detector configuration and 97.1 keV gamma-emiss...
Due to limited sources of natural uranium, Department of Atomic Energy (DAE) has sought thorium (Th) as an alternative source of nuclear fuel. India has one of the largest deposits of natural Th in the form of monazite in Kerala. The currently known Indian Th reserves amount to 155,000 GWe-yr of electrical energy and can meet the energy requirements during the next century and beyond. Thorium-2...
