Preliminary concept of stochastic model of the tritium cycle in a fusion reactor = by Stefan Taczanowski Download PDF EPUB FB2

In the past, several efforts have been dedicated to the development of tritium cycle model, such as TRIMO, UCLA model, SD-TFE model and TAS model. However, the TRIMO model is mainly developed for ITER without blanket breeding, SD-TFE is for double D fuels scenario, UCLA and TAS model assumed steady burning of plasma and failed to assess dynamic tritium inventory for pulsed fusion Cited by: 4.

System dynamics model of tritium fuel cycle was developed for analyzing stock and flow of tritium in fusion power plants. • Sensitivity of tritium build-up to breeding ratio parameters has been assessed to two plant concepts having 3 GW and GW fusion by: 6.

Attaining tritium self-sufficiency is a critical goal for fusion reactor operated on the D–T fuel cycle. The tritium fuel cycle models were developed to describe the characteristic parameters of the various elements of the tritium cycle as a tool for evaluating the tritium breeding by:   In ITER, six technological solutions for tritium breeding—in the form of test blanket modules plus associated ancillary systems—will be operated and tested for the first time.

Their experimental validation will represent a major step for fusion development beyond ITER, when tritium fuel will necessarily have to be bred within the reactor. A transient tritium permeation model is developed based on a simplified conceptual DT-fueled fusion reactor design.

The major design features described in the model are a solid breeder blanket, a low pressure purge gas in the blanket, and a high pressure helium primary coolant.

Tritium inventory in the breeder is considered to be due to diffusive hold-up and solubility by: 6. IAEA TM on Fusion Power Plant Safety, JulyIoana R. Cristescu slide # 1 FUSION FZK - EURATOM ASSOCIATION Tritium Inventories and Containment Philosophy for the Fuel cycle of ITER I.

The code (FUS-TPC) is a new fusion-devoted version of the fast-fission one called Sodium-Cooled Fast Reactor Tritium Permeation Code (SFR-TPC). The main features of the model inside the code are. In this report, after brief introduction on Tritium related researches in Japan, important T issues to be solved for establishment of a fusion reactor will be summarized considering the handling.

Construction of the first experimental fusion reactor ITER has been commenced in Cadarache (France). ITER is a joint international research and development project that aims to.

It follows from the published data on the selection of lithium materials for the breeding zone of a thermonuclear reactor [43–45] that the tritium production involves large-scale radiochemical installations for the conversion of the irradiated material and the extraction of the pure isotope which is present in extreme dilution.

When such radiochemical installations are built, a set of basic Cited by: 2. ELSEVIER Fusion Engineering and Design 28 () Fusion Engineering and Design Time-dependent tritium inventories and flow rates in fuel cycle components of a tokamak fusion reactor W.

Because only a small proportion of the fuel is consumed by the fusion reaction in the tokamak reactor where the fusion reaction takes place, the tritium plant of ITER captures plasma exhaust and processes it for reintroduction into the by: 1.

By recycling the 3 He produced from the decay of tritium back into the fusion reactor, the fusion reactor does not require materials resistant to fast MeV ( pJ) neutrons. Assuming complete tritium burn-up, the reduction in the fraction of fusion energy carried by neutrons would be only about 18%, so that the primary advantage of the D-D fuel cycle is that tritium breeding would not be required.

ITER, or the fusion power plants to follow, will have to manage the radiation produced through two mechanisms. One of the fusion fuels, tritium, is a radioactive form of hydrogen with a half-life of years; the tritium absorbed by the infrastructure of the tokamak will give rise to some radioactivity.

Tritium in the Fuel Cycle of a D-3 He Fusion Reactor.A water-cooling solid breeder blanket is a prime candidate for the blanket of the fusion reactor in Japan.

In this case, the blanket tritium recovery system will be composed of three processes: tritium recovery from helium sweep gas as hydrogen, that as water vapour and tritium recovery from coolant water.The successful development of tritium breeding—that is the generation within the fusion reactor of tritium fuel—is essential for the future of fusion electricity.

ITER will provide a unique opportunity to test mockups of breeding blankets, called Test Blanket Modules (TBM), in a real fusion environment.
