【摘要】 利用MCNP程序计算了不同燃耗下脉冲堆调节棒的微分价值,并采用周期法实验测量了调节棒的微分价值,对比了在不同燃耗下脉冲堆调节棒的微分价值实验值和理论计算值。结果表明:随着脉冲堆燃耗的加深,调节棒在高度200mm以下微分价值变化不明显,在高度200~390mm时,燃耗越深,微分价值越大,理论值与实验值符合很好。更多还原

【Abstract】 In this paper,Monte Carlo N-Particle(MCNP)program is used to calculate and analyze the differential worth of the adjuster rod(rod D)for Xian Pulsed Reactor with various burnup,and period method is used to measure the differential worth of rod D experimently.The experimental values of the differential worth of rod D are compared with theorical ones.The results indicate that the differential worth of rod D does not change significantly when the height of rod is less than 200 mm,and while the height of rod D is 200-390 mm,the deeper the burnup is,the greater the differential worth will be.更多还原
