Kerma factors for calculating the absorbed dose of 15–150 MeV neutrons

Conclusions A hybrid geometrically dependent model has been used to calculate the yield of charged particles in inelastic neutron—nuclear reactions involving elements which form part of the human tissue and are used in particle detectors, for primary nucleon energies up to 150 MeV. The hybrid model is found to give considerably better agreement with experimental data than the cascade—evaporative and cascade—exciton models in the entire energy range considered. The error in calculating the kerma factors using the hybrid model is estimated as ∼6–10%, which is considerably more accurate that the previously published data. Calculated detailed energy dependences are given of the neutron kerma factors for C, O, N, H, Si, and also for soft biological tissue and certain particle detectors.

Recent Progress of HT-7U Superconducting Tokamak

HT-7U is a superconducting tokamak. which is being constructed in Institute of Plasma Physics, Chinese Academy of Sciences. The mission of the HT-7U project is to develop a scientific and engineering basis of the steady state operation of advanced tokamak.The engineering design of the device has been optimized. The R&D program is going on. Short samples of the conductor and a CS model coil were tested. All the TF and PF coils will be manufactured and tested in Institute of Plasma Physics. Therefore, a 600-meter long jacketing line for cable-in-conduit conductors along with two winding machines, a set of VPI equipment and a test facility for the TF and PF coils are ready in ASIPP now. In this paper, the recent progress of the HT-7U is described.

Long-time neutron-temperature dynamics of fast-neutron systems in supercritical emergency regimes

The results of experimental and computational investigations of the long-time (≤60 h) behavior of the BIR-2M and BIGR pulsed reactors with abrupt transfer into a supercritical state under conditions with no externally initiated reactivity changes are presented. These conditions simulate possible incidents when all mechanisms for regulating reactivity and emergency protection fail. The computational characteristics of the accidental fission burst in a metallic critical assembly consisting of highly enriched uranium on the FKBN-2M stand, which occurred at the All-Russia Scientific-Research Institute of Experimental Physics on June 17, 1997, are presented, 6 figures, 1 table, and 6 references.
