在东风-Ⅲ号零功率堆的H方案中,用源倍增法测量了几组镉棒的负反应性,并与脉冲中子源法做了比较。测量结果说明,两者在5%的范围内符合。
In the H scheme of zero-power reactor of Dongfeng-Ⅲ, the negative reactivity of several cadmium rods was measured by the source doubling method and compared with the pulsed neutron source method. The measurement results show that the two are within the 5% range.
