Reliability assessment of high energy particle induced radioactivity calculation code DCHAIN-SP 2001 by analysis of integral activation experiments with 14MeV neutrons

Kai, Tetsuya; Maekawa, Fujio; Kasugai, Yoshimi; Kosako, Kazuaki*; Takada, Hiroshi; Ikeda, Yujiro

JAERI-Research 2002-005, 65 Pages, 2002/03

JAERI-Research-2002-005.pdf:2.75MB

Reliability assessment for the High Energy Particle Induced Radioactivity Calculation Code DCHAIN-SP 2001 was carried out through analysis of integral activation experiments with 14-MeV neutrons. The following three series of experiments conducted at the D-T neutron source facility, FNS, in JAERI were employed: (1) the decay gamma-ray measurement experiment for fusion reactor materials, (2) the decay heat measurement experiment for 32 fusion reactor materials, and (3) the integral activation experiment on mercury.As a result, it was found that the calculations with DCHAIN-SP 2001 predicted the experimental data for (1)$$sim$$(3) approximately within 30%, 20% and 20%, respectively. It was concluded that the activation cross section data below 20 MeV and the associated decay data as well as the calculation algorithm for solving the Beteman equation that was the master equation of DCHAIN-SP were adequate.

Measurement of activation cross sections for mercury isotopes in the neutron energy range between 13.4 and 14.9MeV

Kasugai, Yoshimi; Maekawa, Fujio; Ikeda, Yujiro; Takeuchi, Hiroshi

Journal of Nuclear Science and Technology, 38(12), p.1048 - 1056, 2001/12

https://doi.org/10.3327/jnst.38.1048

Activation cross sections for mercury isotopes have been measured at neutron energy between 13.4 and 14.9 MeV by means of the activation method using Fusion Neutronics Source (FNS) at Japan Atomic Energy Research Institute (JAERI). Measured cross sections are $$^{196}$$Hg(n, 2n)$$^{195m,g}$$Hg, $$^{198}$$Hg(n, 2n)$$^{197m,g}$$Hg, $$^{198}$$Hg(n, p)$$^{198g}$$Au, $$^{199}$$Hg(n, p)$$^{199}$$Au, $$^{200}$$Hg(n, p)$$^{200m,g}$$Au, $$^{201}$$Hg(n, p)$$^{201}$$Au, $$^{202}$$Hg(n, p)$$^{202}$$Au, $$^{204}$$Hg(n, 2n)$$^{203}$$Hg and $$^{204}$$Hg(n, p)$$^{204}$$Au. The cross sections of the $$^{202}$$Hg(n, p)$$^{202}$$Au and $$^{204}$$Hg(n, p)$$^{204}$$Au reactions were measured for the first time. For the $$^{196}$$Hg(n, 2n)$$^{195m,g}$$Hg, $$^{198}$$Hg(n, 2n)$$^{197m,g}$$Hg, $$^{198}$$Hg(n, p)$$^{198g}$$Au and $$^{199}$$Hg(n, p)$$^{199}$$Au reactions, the cross sections at plural neutron energies were measured for the first time. The present data were compared with the experimental data reported previously and the recent evaluations, and it was shown that some evaluations need to be improved.
