 Without A Separate Spallation Target for (p,n) Reaction&description=We introduce the idea of using liquid lead which makes not only a coolant but also a spallation target for (p,n) reaction in Accelerator-driven sub-critical reactor system (ADS). So the target will not need to be replaced during nuclear reactor operation. The entire volume of liquid lead on the path of the incident proton beam in the ADS will be the spallation target; therefore, the number of neutrons generated is not less than those generated by the conventional target method. We provide preliminary calculations illustrating the above ideas. We present two models to calculate the number of neutrons and the neutron multiplicity using database of JENDL/HE library [11]. The number of neutrons and the neutron multiplicity are calculated with the proton beam bombardment on the liquid lead coolant at beam energies of 200 MeV, 250 MeV, 350 MeV, 500 MeV, 600 MeV, 700 MeV, 800 MeV, 1000 MeV and 1500 MeV. The calculated results are compared with the available data [8].&picture=http://www.aascit.org/aascit/decorators/img/journal/909.jpg)
