Thermal-hydraulic analysis of the TRADE spallation target

Deterministic and Monte Carlo modeling and analyses of YALINA-THERMAL subcritical assembly.

“…The results of Table XI show that the difference between the corrected experimental k eff and the MCNP/MCNPX k eff with one detector model (second row of Table X) is between 400 and 1200 pcm. The statistical error of the corrected k eff is between 180 and 400 pcm, which has been calculated with Equations 10,22,and 23. The present numerical results have been obtained by MCNPX using the fuel composition of the IAEA benchmark specifications, 40,42 which is reported in Table XII. This composition neglects the presence of 234 U and the fuel impurities.…”

“…[1][2][3][4][5][6][7] These transmuters are referred to as Accelerators Driven Systems (ADS). Research programs for partitioning and transmuting nuclear waste by ADS are under development in Japan, [8][9][10][11] China, 12 Europe, [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] and Russia. [32][33][34] In Europe, the MUSE program was carried out at the MASURCA facility in Cadarache, France.…”

“…Another set of experiments has been carried out within the TRIGA Accelerator Driven Experiment (TRADE) program. [20][21][22][23][24][25] Another related program is the RACE-T. 26 The current European research and development activity aims at the construction of a multipurpose prototype ADS for nuclear waste transmutation. Two major projects are under consideration: the PDS-ADS [27][28] and the MYRRHA/XT-ADS.…”

Nuclear and thermal-hydraulics analysis of spallation window targets

“…This spallation source was defined in the TRADE project [24] where a subcritical TRIGA reactor was intended to be coupled with a cyclotron accelerator. The main goal of the experiment was the analysis of the dynamic behaviour of a subcritical core fed with neutrons by a spallation target.…”

Dynamic response of an accelerator driven system to accelerator beam interruptions for criticality

“…Those components can be developed separately, but they must be coupled for the full operation of an ADS, and they must be analyzed as a chain in order to characterize the ADS behavior and to asses its internal coherence. Several works have been carried out to describe the behavior of a subcritical device, including safety analysis to account for reactivity insertion accidents, kinematic response of the system, and so forth [9][10][11].…”
