Nuclear performance analyses for HCPB test blanket modules in ITER

Fusion Engineering and Design, 2007
Neutronic, shielding and activation analyses have been performed for recent design variants of the Helium Cooled Pebble Bed (HCPB) test blanket module (TBM) in ITER on the basis of 3D Monte Carlo calculations. The main objective has been to assess and optimise the nuclear performance of the HCPB test blanket modules in terms of the tritium generation ...

Tritium transport analysis in HCPB DEMO blanket with the FUS-TPC code

Fusion Engineering and Design, 2013
Abstract In the breeding areas a significant fraction of the tritium produced is extracted out from the Breeding Zone by the He gas purging the breeding ceramic in the helium cooled pebble bed (HCPB) blanket concept or transported in solution by the flowing liquid metal alloy in the helium cooled lead lithium (HCLL) blanket concept and then extracted

Analysis of three LOCAs for the European HCPB test blanket system

Fusion Engineering and Design, 2007
Three LOCA sequences have been analysed in the frame of the safety assessment of the European helium cooled pebble bed (HCPB) test blanket module (TBM) system. These three sequences have been selected as representative of accidents judged to cover all scenarios envisaged in the design basis involving the TBMs. The three groups of accidents investigated

Test Strategy for the European HCPB Test Blanket Module in ITER

Fusion Science and Technology, 2005
According to the European Blanket Programme two blanket concepts, the Helium Cooled Pebble Bed (HCPB) and a Helium Cooled Lithium Lead (HCLL) will be tested in ITER. During 2004 the test blanket modules (TBM) of both concepts were redesigned with the goal to use as much as possible similar design options and fabrication techniques for both types in ...

Tritium Behavior in HCPB Breeder Blanket Unit: Modeling and Experiments

Fusion Science and Technology, 2017
AbstractTritium behavior in a breeding blanket is a key design issue because of its impact on safety and fuel self-sufficiency best performance. Considering the difficulty in handling and its high cost, it is intended to prepare a simulation tool for tritium transport in the HCPB (Helium Cooled Pebble Bed) breeder blanket unit concept. The objective of

Tritium permeation through the first wall of the EU-HCPB blanket

Fusion Engineering and Design, 2000
The Helium Cooled Pebble Bed (HCPB) blanket is one of the two concepts to be further developed for a European DEMO power reactor. Tritium leakage due to the permeation through the main structural materials constitutes one of the main problems of the fusion technology.

Preliminary engineering assessment of the HCLL and HCPB Neutron Activation System

2015 4th International Conference on Advancements in Nuclear Instrumentation Measurement Methods and their Applications (ANIMMA), 2015
The Neutron Activation System (NAS) is one of the four types of neutronics sensors considered for the testing of the HCLL and HCPB Test Blanket Module (TBM) in ITER. It measures the absolute neutron flux intensity with information on the neutron spectrum in selected positions of the TBM.
