Neutronics experiment on a helium cooled pebble bed (HCPB) breeder blanket mock-up

A neutronics experiment has been performed in the frame of European Fusion Technology Program on a mock-up of the EU Test Blanket Module (TBM), Helium Cooled Pebble Bed (HCPB) concept, with the objective to validate the capability of nuclear data to predict nuclear responses, such as the tritium production rate (TPR), with qualified uncertainties. In the experiment, the TPR has been measured using Li$$_{2}$$CO$$_{3}$$ pellets at various depths at two symmetrical positions at each depth, one in the upper and one in the lower breeder cassette. Three independent measurements were performed by ENEA, TUD/VKTA and JAEA. The neutron flux in the beryllium layer was measured as well using activation foils.

International benchmark activity of tritium measurement of blanket neutronics

Ochiai, Kentaro; Verzilov, Y. M.; Nishitani, Takeo; Batistoni, P.*; Seidel, K.*

To evaluate the measurement accuracy of the tritium production from $$^{6}$$LiLi(n,t)$$^{4}$$He reactions, an international benchmark program was initiated again under the frame work of an IEA fusion neutronics subtask from 2003. JAERI, ENEA and Technical University of Dresden (TUD) are participating in the activity. This program consists of the calibration of the tritium measurement systems and the verification of the measurement accuracies of the tritium production from $$^{7}$$Li(n,nt)$$^{4}$$He and $$^{6}$$LiLi(n,t)$$^{4}$$He reactions. We have completed the calibration of the measurement system with tritium standard water (HTO) and blind HTO samples. From the results, the scattering of the calibration was within 1.5 %.
