Production of Tc-99m from naturally occurring molybdenum absent uranium

K. Pagdon; C. Gentile; A. Cohen; G. Ascione; G. Baker 2011 IEEE/NPSS 24th Symposium on Fusion Engineering, 2011

Technetium-99m (Tc-99m) is the world's most widely used medical isotope. Current production methods involve the irradiation of highly enriched uranium (HEU) and low enriched uranium (LEU) targets in nuclear reactors. Molybdenum-99 (Mo-99) is then extracted from these targets, which decays to Tc-99m. Currently, this process is centralized, as there are very few companies that manufacture Mo-99. In an effort to ...


New layout of the rings for the 0.5 MW/10 Hz/50 Hz AUSTRON spallation source

M. Benedikt; P. Bryant; H. Schonauer; M. Regler PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2001

In 1993-94 a feasibility study for AUSTRON, a neutron spallation source, was made. At that time the machine was a synchrotron cycling at 50 Hz and delivering an average beam power of 410 kW at 1.6 GeV. In 1998, the Austrian Government decided to contribute one third of the total cost of the facility and invited international partners to participate. ...


The collimation system of the SNS transfer lines

N. Catalan-Lasheras; D. Raparia PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2001

The High Energy Beam Transport (HEBT) and Ring to Target Beam Transport (RTBT) lines of the Spallation Neutron Source (SNS) include collimation systems that protect the line itself, as well as the systems downstream. Due to the one- pass mechanism in a transfer line, collimation can only provide protection against accidental losses while shaping the beam is reserved for multi-pass ...

The GUINEVERE (Generation of Uninterrupted Intense NEutron pulses at the lead VEnus REactor) project was launched in 2006 within the framework of FP6 EUROTRANS in order to validate online reactivity monitoring and subcriticality level determination in accelerator driven systems (ADS). Therefore, the VENUS reactor at SCK-CEN in Mol, Belgium, was modified towards a fast core (VENUS-F) and coupled to the ...


Dependence of the SNS transfer lines and accumulator ring on linac energy

D. Raparia; Y. Y. Lee; J. Wei; W. T. Weng PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2001

One of the options considered for the SNS linac, to reduce the cost, was to lower the energy to 840 MeV and leave space in the tunnel for a future upgrade to 1.3 GeV either by adding cryo-modules or increasing the gradient in the SC linac. A linac energy other than 1.0 GeV will have an impact on the transfer ...

  • Nuclear Power

    Nuclear power plants utilize the energy released in a nuclear reaction as the source of thermal energy to heat steam which in turn drives a steam turbine that is connected to a generator to generate electricity. The most common fuel used as a source of this nuclear reaction is uranium. This chapter discusses the differences between alpha, beta, gamma, and neutron byproducts of nuclear reactions. A reactor is a vessel that contains the nuclear fuel, control rods, and other systems to support the nuclear reaction. The boiling water reactor BWR design utilizes light water for both coolant and moderator. The boiling water reactor (BWR) only has one loop and the reactor is the "boiler" in the thermodynamic cycle. The pressurized heavy water reactor (PHWR) uses heavy water as the moderator. Heavy water is a molecule that contains deuterium and oxygen as compared with light water which is a molecule that contains hydrogen and oxygen.

  • Analysis of Neutron Damage in HighTemperature Silicon Carbide JFETs

    Neutron-induced displacement damage effects in n-channel, depletion-mode junction-fleld-effect transistors (JFETs) fabricated on 6H-silicon carbide are reported as a function of temperature from room temperature (RT) to 300°C. The data are analyzed in terms of a refined model that folds in recently reported information on the two-level ionization energy structure of the nitrogen donors. A value of 5 ± 1 cm-3 per n/cm2 is obtained for the deep- level defect introduction rate induced by the neutron irradiation. Due to partial ionization of the donor atoms at RT, the carrier removal rate is a function of temperature, varying from 3.5 cm-1 at RT to 4.75 cm-1 at 300°C. The relative neutron effect on carrier mobility varies with temperature approximately as T-7/2, dropping by an order of magnitude at 300°C compared with the RT effect. The results offer further support for the use of SiC devices in applications which combine high-temperature and severe radiation environments, where the use of Si and GaAs technologies is limited.

  • Phonon Transport in Si Nanostructures

    This chapter develops a Monte Carlo (MC) method for solving the phonon Boltzmann transport equation (BTE) to perform more accurate heat transfer simulations in nanoscale Si devices. In order to evaluate the thermal conductivity, one can adopted one particle MC method, which enables obtaining the statistical convergence efficiently. The chapter uses the MC simulator to analyze the quasi¿¿¿ballistic phonon transport effect on the heat conduction in Si. It considers that the MC method is a good tool for studying the mixture regime between the ballistic and diffusive nature for the phonon transport. The chapter shows the realistic dispersion relation of phonons in bulk Si calculated from the adiabatic bond charge model, whose accuracy was validated through comparison with experimental neutron scattering data. The thermal conductivity of Si nanowires (SiNWs) was also calculated using the MC simulator. In nanostructures, phonons are frequently scattered at boundaries, which significantly impedes heat conduction.
