PGNAA system preliminary design and measurement of IHNI

Zhang Zichu,Li Lihua,Gao Jijin,Fu Jinshu

Strategic Study of CAE 2012, Volume 14, Issue 8, Pages 28-32

Abstract:

The preliminary design of PGNAA system of IHNI was completed and the system in accordance with the design was set up. For both detector shielding part and the neutron beam shielding part, the inner layer was natural LiF powder and the outer was lead.Then boron concentration measurement experiments using this system were finished.The results show that the the system can measure ¹⁰B concentration of 10 ppm, with 2 mL of the sample volume. ¹⁰B element measurement sensitivity was 0.822 cps/ppm. Also it was found that the natural LiF powder would produce a high background in the target part of the energy spectrum and affect the measurement accuracy.

Performance and characteristic of in-hospital neutron irradiator

Li Yiguo,Xia Pu,Peng Dan,Zou Shuyun,Wu Xiaobo,Zhang Jinhua,Zhang Zizhu,Gao Jijin,Wang Liyu,Fu Jinshu,Liu Tong,Zhou Yongmao

Strategic Study of CAE 2012, Volume 14, Issue 8, Pages 20-22

Abstract:

The design of in hospital neutron irradiator (IHNI) and its systems were introduced, and the performance and characteristics of IHNI were described. In order to test the inherent safety of IHNI, the experiment of 4.2 mk reactivity release was done. The experimental results showed that the peak power of IHNI was 85.7 kW at the time of 229 s after 4.2 mk reactivity release, and then, the power decreased owing to the negative temperature coefficient of moderator. The radiation dose rates at different rooms were lower than the standard value.
