Simulation of (16)O (n, p) (16)N reaction rate and nitrogen-16 inventory in a high performance light water reactor with one pass core
(Applied Radiation and Isotopes; Elsevier, 2014-12)
The rate of activation of the isotope (16)O to (16)N in a typical HPLWR one pass concept was calculated using MCNP code. A mathematical model was used to track the inventory of the radioisotope (16)N in a unit mass of ...
Evaluation of permutite for removal of radiocobalt from nuclear wastewater
(Journal of Radioanal Nucl Chem, 2014-07)
A synthetic zeolite, commercially available as permutite was tested for removing radiocobalt from aque- ous solutions by sorption. The sorption process was studied as a function of contact time, pH, ionic strength and solid ...
Investigation of photoneutron and capture gamma-ray production in Pb and W under irradiation from 16N decay radiation
(Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms; Elsevier, 2015-09)
Lead and tungsten are potential alternative materials for shielding reactor ex-core components with high 16N activity when available space limits application of concrete. Since the two materials are vulnerable to photonuclear ...
Evaluation of candidate materials for SCWR turbine and balance of plant shielding
(Progress in Nuclear Energy; ScienceDirect, 2015-03)
Since the coolant leaving the SCWR core contains an assortment of radioisotopes, it is necessary to identify appropriate materials for shielding ex-core components. Photon attenuation characteristics, photo-neutron production ...
Design and optimization of HPLWR high pressure Turbine gamma ray shield
(Nuclear Engineering and Design; Elsevier, 2015-04)
This work proposes the optimum gamma ray shield thickness around the HPLWR high pressure turbine for different occupancy periods in the turbine building. Monte Carlo method was employed in the design process and only ...
