An additional performance of HTRS: the waste radiotoxicity minimisation
Radiation Protection Dosimetry, 2005The management of radioactive waste is a key issue for the present and future use of nuclear energy. In this frame, high temperature reactors (HTRs) have, among others, the capability to burn actinides. After a short introduction on HTRs, the performances of two MC-based burnup codes (Monte Carlo continuous energy burnup and MONTEBURNS) in assessing ...

Der Reaktorkern eines HTR, hier sei speziell der des THTR-300 betrachtet, besteht aus einer statistischen Schuttung von Graphitkugeln mit 6 cm Durchmesser (siehe Abb. 4.1 und Abb. 4.2). Im THTR wird so in einem Reaktorvolumen von 125 m3 (Durchmesser des Kerns = 5,6 m, mittlere Hohe des Kerns = 5,1 m) eine thermische Leistung von 750 MW bereitgestellt ...

The design features of the HTR-10
Nuclear Engineering and Design, 2002The 10 MW High Temperature Gas-cooled Test Reactor (HTR-10) is a modular pebble bed type reactor. This paper briefly introduces the main design features and safety concept of the HTR-10. The design features of the pebble bed reactor core, the pressure boundary of the primary circuit, the decay heat removal system and the two independent reactor ...

Abstract The HTR in future can be realized with inherent safety. Low power density of the core, high heat capacity as a heat sink and high temperature stable ceramic fuel elements exclude the serious release of fission products in all accident situations. By a new development of SiC-envelopes on the surface of the spherical fuel elements, a promising

Japan's future HTR—the GTHTR300
Nuclear Engineering and Design, 2004JAERI started design and development of the high temperature gas cooled reactor with a gas turbine electric generation system, the GTHTR300, in April 2001. The GTHTR300 is expected to be a new electric generation system in the early 2010s. Design originalities of the GTHTR300 are a horizontally mounted highly efficient gas turbine system and an ...

Abstract High temperature nuclear reactors will address mainly the industrial cogeneration market and compete with gas cogeneration, the current reference technology. The key question for HTR is therefore: how far are HTRs competitive against gas technologies? This simple question demands a complex response.

Industrial aspects of revisited HTRs
Nuclear Engineering and Design, 2001Abstract The ‘new’ High Temperature Reactors (HTRs) are based on the direct gas turbine cycle which brings high inherent safety together with high efficiency. This combination makes them attractive cost-wise for countries with small and medium size grids that cannot afford larger units.

An introduction to titanium minerals is provided along with a brief history of high tension roll (HTR) separation and its applications. Current HTR theory is critically reviewed and deficiencies in previous modelling work are identified. These problems are recognised as the likely reason why past models required empirical manipulation to reproduce ...

The Renewal of HTR Development in Europe
10th International Conference on Nuclear Engineering, Volume 2, 2002The European HTR-Technology Network (HTR-TN), created in 2000, presently groups 20 organisations from European nuclear research and industry for developing the technologies of direct-cycle modular HTRs, which presently raise a large world-wide interest, because of their high potential for economic competitiveness, natural resource sparing, safety and ...
