| 英文摘要 | The china spallation neutron source (csns) is a short-pulsed neutron scattering facility. the beam power is designed to be 100 kw in phase i, with the capability of upgrading to 500 kw. tantalum (ta)-cladded tungsten (w) was chosen as the spallation target due to its high neutron yield. ta claddings can solve the problem of the corrosiveness of w plates, although they produce high decay heat after intense irradiation. this paper presents the decay heat distributions and evolutions for the future upgraded 500 kw w ta spallation target. the calculations are performed using the mcnpx2.5 monte carlo code and the cinder'90 activation code. the decay heat distributions show that for the w plates, decay heat is mainly produced via the spallation reaction process, whereas for the ta claddings, it is mainly produced via the neutron capture process. an effective method of reducing the decay heat in the w ta target is also presented and discussed.
