Important technological and physics issues related to long pulse operation required for a reactor are now being addressed in Tore Supra. experimental results in conditions where all the plasma facing components are actively cooled during pulses exceeding six minutes. Important physics issues related to continuous operation are observed in non inductively driven plasmas.

The aim of the current study was to assess the safety of bronchoscopy-guided radiofrequency ablation (RFA) and compare the effectiveness between new internal cooled-RFA and standard noncooled-RFA. Normal lungs from sheep were used (n=6). Internal cooled-RFA and standard noncooled-RFA were set to assess the most suitable RFA conditions, such as power output, flow rate and ablation time. Internal...

High-temperature gas-cooled reactor fuels are composed of thousands of microscopic fuel particles, randomly dispersed in a graphite matrix. The modelling of such geometry is complicated, especially using continuous-energy Monte Carlo codes, which are unable to apply any deterministic corrections in the calculation. This paper presents the geometry routine developed for modelling randomly disper...

The paper presents the main results of the insights to a gas cooled reactor from the perspective of the following notions: probability, uncertainty, entropy and risk. Some results of the ongoing comparisons between the insights obtained from three models are presented. The approaches consider the PBMR nuclear power plant (NPP) as a thermodynamic installation and as a hierarchical system with or...

Benchmark Experiments, Development and Needs in Support of Advanced Reactor Design 10 nuclear reactor designs will for the most part be a departure from low enrichment light 11 water (LWR) currently operated around world. Such advanced include 12 but are not limited to new TRISO-fueled high temperature gas reactors, heat-pipe cooled micro-13 fluoride salt high-temperature molten lead fast 14 th...

The present paper describes the experimental campaign executed at ENEA Brasimone Research Centre aiming supporting development of a PbLi/water heat exchanger suitable for lithium–lead loops dual coolant lithium lead and water cooled breeding blankets EU DEMO fusion reactor. experiments were performed in test section named HERO, installed inside main vessel lead–bismuth eutectic-cooled pool-type...

The Pebble Bed Advanced High Temperature Reactor (PB-AHTR) is a liquid-salt cooled reactor that uses conventional TRISO fuel. Due to the high thermal inertia of the liquid salt coolant, the PB-AHTR allows for a much higher power-density core than traditional gas-cooled high temperature reactors. High power density has a favorable economic impact. In 2007, the baseline design 2400MWth PB-AHTR wa...
