The High Flux Reactor (HFR) Petten, managed by the Insti-tute for Energy (IE) of the JRC of the European Commission, is one of the most powerful multi-purpose materials testing reactors in the world. The HFR is of the tank-in-pool type, light water cooled and moderated and operated at 45 MW.

A high flux reactor is comprised of a core which is divided into two symetric segments housed in a pressure vessel. The core segments include at least one radial fuel plate. The spacing between the plates functions as a coolant flow channel.

The core segments are spaced axially apart such that a coolant mixing plenum is formed between them. High Flux Isotope Reactor Upgrade and User Program—ORNL tering, isotope production, materials irradiation, and facilities man-agement.1 METHODS/APPROACH The external review committee centered its focus on the HFIR and discussed other facilities only insofar as they directly affected the functioning of the HFIR.

The analytical and research capabilities of a research reactor are determined primarily by the available thermal neutron flux. This database categorises research reactors as a low flux, medium flux, or high flux reactor according to the following levels of thermal neutron flux: low flux reactor.

This requirement led to setting up of a new MW (thermal) research reactor, Dhruva. The reactor attained its first criticality on 8th August and commenced the full power operation on 17th January Dhruva is a high power research reactor with a maximum thermal neutron flux level of × 10 14 n/cm 2 /s.

The reactor system is. @article{osti_, title = {Operating manual for the High Flux Isotope Reactor. Volume I. Description of the facility}, author = {}, abstractNote = {This volume contains a comprehensive description of the High Flux Isotope Reactor Facility.

Currently there are two vitrification plants operational at Trombay and Tarapur and a third plant is under construction at Kalpakkam.

Waste immobilization plant, Trombay The plant located at Trombay essentially undertakes vitrification of HLW produced during the reprocessing of spent fuels of Trombay based research reactors (Fig).

overview of the applications of research reactors [1, 2]. In this paper we provide a perspective of various major utilization programmes that may be pursued at any research reactor and discuss relevance to low flux ( neutrons/cm2/s) and medium flux reactors up to 1x neutrons/cm2/s.

The programmes may include the following. The Critical Facility, a low power research reactor of W nominal power, constructed in BARC as a part of the over-all technology development programme to validate the physics design of thorium based AHWR, attained first criticality at hrs on April 7, The reactor core is currently loaded with natural uranium fuel assemblies.

The High Flux Isotope Reactor (HFIR) in the United States and the SM-3 reactor in Russia are the only two research reactors in the world currently producing Cf.

The primary alternative to research reactors for transmutation applications is the use of accelerators, either for direct irradiation with charged particles or for generation of. Reactor performance of a high flux circulating fluidized bed (CFB) downer is studied under superficial gas velocities of 3–7 m/s with solids circulation rate up to kg/m 2 s using ozone decomposition reaction.

Results show that the reactant conversion in the downer is closely related to the hydrodynamics, with solids holdup being the most influential parameter on ozone decomposition.

The High Flux Reactor (HFR) in Petten is one of the most powerful multi-purpose materials testing reactors in the world. It is owned by the European Commission and operated by the Dutch Nuclear Research and consultancy Group.

The HFR is a tank in pool type light water-cooled and moderated reactor, operated at 45 MW. A MWt reactor design has been conceived to support flux level of the order of n/cm2/s in selected flux trap zones. The physics design considers high enriched metallic alloy fuel in the form of annular plates placed in a D2O moderator tank in a hexagonal lattice arrangement.

By choosing a tight lattice pitch in the central region and double the lattice pitch in the outer region, it is.

Also known as teaching reactor. Research Reactor a nuclear reactor that is a source of neutron and gamma. In research reactors, plate-type fuel elements are generally adopted so as to produce high power densities and are cooled by a downward flow. A core flow reversal from a steady-state forced downward flow to an upward flow due to natural convection should occur during operational transients such as “Loss of the primary coolant flow”.

While research into fuel conversion of the HFIR is ongoing, the process is expected to take several years and HFIR is currently scheduled to be the last research reactor operating with HEU fuel in the United States.

ORNL researchers are currently using multiphysics simulation to explore and verify new designs for the reactor running on LEU fuel. Operating at 85 MW, HFIR is the highest flux reactor -based source of neutrons for condensed matter res earch in the United States, and it provides one of the highest steady-state neutron fluxes of any research reactor in the world.
