Determining the effectiveness of nuclear security through computer simulation
(2015-09-01)
There is a growing concern from both national regulators and the International
Atomic Energy Agency (IAEA) about the threat posed by attacks against iconic targets such as nuclear power plants. This has led to an increased ...
Development of a heat-transfer correlation for supercritical water in supercritical water-cooled reactor applications
(2009-12-01)
A large set of experimental data, obtained in Russia, was analyzed and a new heat-transfer correlation for supercritical water was developed. This experimental dataset was obtained within conditions similar to those for ...
Simulation, design and construction of a gas electron multiplier for particle tracking
(2012-12-01)
The biological effects of charged particles is of interest in particle therapy, radiation protection and space radiation science and known to be dependent on both absorbed dose and radiation quality or LET. Microdosimetry ...
Sensitivity analysis of fuel centerline temperatures in SuperCritical water-cooled reactors (SCWRs)
(2012-12-01)
SuperCritical Water-cooled Reactors (SCWRs) are one of the six nuclear-reactor concepts currently being developed under the Generation-IV International Forum (GIF). A main advantage of SCW Nuclear Power Plants (NPPs) is ...
Study of heat transfer in a 7-element bundle cooled with the upward flow of supercritical Freon-12
(2012-04-01)
Experimental data on SuperCritical-Water (SCW) cooled bundles are very limited. Major problems with performing such experiments are: 1) small number of operating SCW experimental setups and 2) difficulties in testing and ...
Development and characterization of a dual neutron and gamma detector
(2011-08-01)
A dual neutron and gamma detection system has been developed for online measurements. The system consists of a single crystal mounted on a photomultiplier tube to detect simultaneously gamma radiation as well as thermal ...
Low energy photon mimic of the tritium beta decay energy spectrum
(2013-04-01)
Tritium is a radioactive hydrogen isotope that is typically produced via neutron interaction with heavy water (D2O), producing tritiated water (DTO). As a result of this, tritium accounts for roughly a third of all ...
Leakage-corrected discontinuity factors for a second-generation Th-Pu pressure-tube SCWR.
(2014-08-01)
The neutron flux throughout a reactor core should be calculated, ideally, by solving the neutron transport equation for a highly detailed geometric model of the core. Since this is computationally impractical, approximate ...
Development of a 37-element fuel bundle for the production of molybdenum-99 in CANDU power reactors.
(2014-08-01)
In this study, the potential use of CANDU power reactors for the production of Mo-99 is assessed. Five different modifications of a 37-element fuel bundle that could be used for the production of Mo-99 in existing CANDU ...
Three dimensional heterogeneous finite element method for static multi-group neutron diffusion
(2010-08-01)
Because current full-core neutronic-calculations use two-group neutron diffusion and rely on homogenizing fuel assemblies, reconstructing pin powers from such a calculation is an elaborate and not very accurate process; ...
