The advantage of using heavy water for neutron moderation is that its low thermal neutron capture cross section ( (th), Table 19.3) improves the neutron economy (i.e. 1 - p becomes much less than in LWRs) so that even natural uranium can be used as fuel.

series of measurements of neutron-capture cross sections have been performed on medium-mass ters of the different activation runs are given in Table 1.

The cross section is not in general equal to the actual area of the nucleus. For instance the radiative capture cross section for Au197 at the peak of 4.9 eV resonance is 3x10-20 2cm , whereas the geometrical area of its nucleus is just 1.938x10-24 cm2. The reaction cross section is much greater than the physical cross section of the nucleus

scenario, lead to its release in the environment during long-term storage. But, after neutron capture, 99Tc becomes 100Tc, decaying to the stable isotope 100Ru with a half-life of 16 s. Therefore, 99Tc is a very good candidate for transmutation. Several measurements of the neutron cross sections of 99Tc have been performed in the past [1-5]

Table 1 . In the past, many experimental groups have measured the neutron capture cross sections of 153Eu using the time-of-flight (TOF) method.

The thermal neutron capture cross sections (GO) and the resonance integrals (Io) of some fission products (FP), such as 137Cs, ^Sr, wTc, 129I and 135Cs, were measured by the activation and y-ray spectroscopic methods. Moreover, the cross section measurements were done for other FP elements, such as I27I, 133Cs arid I34Cs. This paper provides

Among the significant findings are the following. The neutron width of the largest resonance in Gd, at 0.032 eV in 157Gd, has been measured to be (9 6 1)% smaller than that given in ENDF/B-VI updated through release 8.
