Study and application of k0-IAEA program on the Dalat Research Reactor

The pneumatic 7-1 and rotary rack (lazy susan) facilities are two main irradiation channels for neutron activation analysis at Dalat research reactor. The experiments for characterizing these two irradiation facilities at June, July and August, 2010 by k0-IAEA using Al-0.1% Au, Al-0.1% Lu, 99.98% Ni and 99.8% Zr monitors were done. The neutron spectrum parameters include: (1) Thermal neutron flux (Φth); (2) The ratio between thermal neutron flux and epi-thermal neutron flux (f); (3) The α factor describing the neutron flux distribution 1/E1+α, and (4) The neutron temperature (Tn). This study provides the first database for further studying and applying k0-IAEA at Dalat Research Reactor in the future. (author)
