Research and Design of Reactor Neutron Source

This paper introduces the research of neutron source design of Ling’ao NPP phase 2 by Monte Carlo code MCNP.The results are in well accordance with the FARMATOME’s design.According to the research,the strength of neutron source of Ling’ao NPP phase 2 can be lowed by changing the location of neutron source,and lower strength will bring considerable economical benefit.
