Analysis of Improvement Plan for Miniature Neutron Source Reactor

This paper analyzes some improvement plans to prolong the single operation time of the Miniature Neutron Source Reactor (MNSR). Test results shows that after adding proper quantity of Be plates on the top Be plates box, the single operation time of MNSR can be greatly prolonged by installing the compensation Cd-plate outside the flank Be-reflector and making the plate and central control rod move together, without any change of central control rod and the original structure of the reactor core. The operation performance of MNSR can be improved.
