  • Helium gas for nuclear reactors case study

    Application Moisture is measured in helium gas used for nuclear reactors. The helium is used as a reactor coolant because of its excellent thermal properties and chemical inertness. Problem If the helium becomes contaminated with moisture, it will cause both degradation of graphite rods and an undesired change in the process's heat balance. At worst, a ...

  • Thermal behaviour of the IPR-R1 TRIGA nuclear reactor

    Experimental and analytical studies have been performed at the Nuclear Technology Development Center ? CDTN (Belo Horizonte) to find out the temperature distribution in the IPR-R1 TRIGA Research Nuclear Reactor, as a function of power and position in the reactor core. The basic safety limit for the TRIGA reactor system is the fuel temperature, both in steady-state and pulsed mode operation. The ...

  • Fractional divergence for neutron flux profile in nuclear reactors

    The concept of fractional divergence is developed for application to the constitutive neutron diffusion equation for describing the neutron flux profile. The analytical solutions for bare reactors in multiplying media and neutron diffusion in non-multiplying media are obtained for fractional-order differential equations. This definition of fractional divergence describes the neutron flux by not ...

  • The renewal of licensing system for nuclear reactors in Indonesia

    This paper describes the renewal of the licensing system for nuclear reactors in Indonesia stipulated in the new legislation and regulations. The new Act, Number 10 Year 1997 on Nuclear Energy, provides for licensing by the regulatory body of personnel and installations. The construction and operation of nuclear reactors and other nuclear installations, as well as the decommissioning of nuclear ...

  • Molybdenum: Manufacturing Process and Use in Nuclear Reactors

    Incandescent lamps used the first molybdenum product in the form of lead wire. This event took place early in the 20th century. Strength and stability of molybdenum at high temperatures were main factors that made it a choice for this application. However, since then molybdenum has found place in many other applications. It has become ...


  • A future for nuclear energy: pebble bed reactors

    Pebble Bed Reactors could allow nuclear plants to support the goal of reducing global climate change in an energy hungry world. They are small, modular, inherently safe, use a demonstrated nuclear technology and can be competitive with fossil fuels. Pebble bed reactors are helium cooled reactors that use small tennis ball size fuel balls consisting of only 9 grams of uranium per pebble to provide ...

  • Coupling a hydrogen production process to a nuclear reactor

    Work is currently underway to define a pre-conceptual design of a hydrogen production plant. The reference case is a VHTR dedicated to hydrogen production using the sulphur-iodine process. The chemical part of the plant is based on a very detailed flow-sheet where all components are listed. Considering the volume and flow-rates of the circulating products, a detailed image of the chemical plant ...

  • Coupling the nickel–iodine–sulphur cycle with a nuclear reactor

    Nuclear hydrogen production is a technically feasible and economically viable option for addressing future energy needs. Several projects have been started on the co–generation of hydrogen and electricity from nuclear energy. In this report, the nickel sulphur iodine (NIS) cycle, a thermochemical water splitting cycle originally developed in ENEA for solar hydrogen production, was studied to be ...

  • Local blockage analysis of lead-cooled next-generation nuclear power reactors

    Local blockage is one of the possible severe accidents which may occur in lead (Pb)- or lead-bismuth (Pb-Bi)-cooled fast reactors due to their high melting temperature. In a local blockage accident, the local temperature increase cannot significantly reduce power level inherently. Therefore, this type of accident should be considered in the core design optimisation of those reactors. In the ...

  • Nuclear desalination complexes based on PWR and gas cooled reactors

    This report is prepared based on the results of activities performed in Russia on the development of energy desalination complexes (EDCs) with different reactor plants. The activities were aimed at the development of conceptual designs for EDCs and evaluation of the EDC from a technical-economic point of view, commercial attractiveness and economic efficiency based on reactor plants such as ...

  • Industrialisation guidelines for South Africa's pebble bed modular nuclear reactor programme

    The industrialisation of any new technical system requires the establishment of the required industrial infrastructure and supplier base for the system. This paper presents a new methodology used for the determination of industrialisation guidelines for South Africa's Pebble Bed Modular Nuclear Reactor (PBMR) programme. The methodology consisted of a number of steps. These were a survey of the ...

  • Nuclear desalination by waste heat utilisation in an advanced heavy water reactor

    The use of thorium for nuclear power generation is an important element of the Indian atomic energy programme. The design and development of the Advanced Heavy Water Reactor (AHWR) is a step in this direction. Intensive design activity is underway to set up a 300-MWe AHWR. The design of the AHWR incorporates several features to simplify the design and to eliminate certain systems and components, ...

  • Study of confinements in the particle swarm optimisation for application to the nuclear reactor reload problem

    Particle Swarm Optimisation (PSO) is a metaheuristic technique based on the social aspects of intelligence. Some PSO models have been developed for combinatorial optimisation, although none of them presented satisfactory results to optimise the combinatorial problem of the Nuclear Reactor Reload Problem (NRRP). The Particle Swarm Optimisation with Random Keys (PSORK) model is a variant of the PSO ...

  • Accuracy in temperature sensor response time estimation for new nuclear reactor designs

    One method for measuring the response time of temperature sensors, the plunge test, verifies that the sensor has a suitable response time in the laboratory before installation. However, plunge test results cannot be extrapolated to the response time in an operating plant because response time is affected by multiple factors such as the ratio of internal heat-transfer resistance to the surface ...
