“…We find that: as R s increases, ψ * increases slightly. This result seems paradox to the conclusion that the bigger of target radius, the smaller of proton efficiency in [12]. In fact,as is seen in Table 4, it is the trade-off between the soft of radial neutrons and the increase of survival neutrons.…”

“…232-Th,238-U, Am can be used as Table 2 Parameters of ADS benchmark [9] The element of IAEA ADS benchmark at BOL (20 10.0 cm fuels of ADS. An external neutron hardly ever induce fissions of these fuels when its kinetic energy is below 1 MeV [12]. The energy spectrum of neutrons in subcritical core is different from that of spallation neutrons; the former is determined by geometry and composition of the system, while the later is mostly determined by the size of spallation region.…”

“…The size of subcritical core changes with the radius of spallation region. It was proved that proton efficiency decrease when radius of spallation region (called target in [12]) increases due to the soft and leakage of neutrons [12]. Changing the size of the subcritical core will bring to change of several factors that influence the proton efficiency.…”

The spatial and energy distribution of spallation neutrons have an effect on the performance of Accelerator Driven Subcritical systems. In this work, the spatial, energy distribution of spallation neutrons and the effect of these factors on proton efficiency was studied. When the radius of spallation region increases, backward neutrons were found to have a rather big ratio and have a positive effect on proton efficiency. By making better use of these neutrons, we may increase the radius of target to satisfy some other requirements in the design of subcritical core.

The GUINEVERE project was launched in 2006, within the 6th Euratom Framework Program IP-EUROTRANS, in order to study the feasibility of transmutation in Accelerator Driven subcritical Systems (ADS). This zero-power facility hosted at the SCK•CEN site in Mol (Belgium) couples the fast subcritical lead reactor VENUS-F with an external neutron source provided by interaction of deuterons delivered by the GENEPI-3C accelerator and a tritiated target located at the reactor core center. In order to test on-line subcriticality monitoring techniques, the reactivity of all the VENUS-F configurations used must be known beforehand to serve as benchmark values. That is why the Modified Source Multiplication Method (MSM) is under consideration to estimate the reactivity worth of the control rods when the reactor is largely subcritical as well as near-critical. The MSM method appears to be a technique well adapted to measure control rod worth over a large range of subcriticality levels. The MSM factors which are required to account for spatial effects in the reactor can be successfully calculated using a Monte Carlo neutron transport code.
