Abstract

The Risø Mesoscale PUFF model (RIMPUFF) is a Lagrangian atmospheric dispersion model that uses consecutive Gaussian puffs to simulate accidental release which is widely used in nuclear emergencies. Based on the real-time puff size and the distance between the puff and the monitoring station, RIMPUFF can calculate the dose results quickly by using the dose calculation interpolation table within its dose calculation module but the results are biased. To improve the accuracy of dose results under the requirement of rapid dose calculation, in this paper, a new interpolation table for dose calculation is proposed utilizing a 3D integral dose calculation method. And the proposed interpolation table was evaluated against the Belgian field experiment. In order to assess the quality of the optimization, the dose results of the new interpolation were compared with that of RIMPUFF, the 3D convolution method and observations from the field experiment. The comparisons indicate that the dose results of the new dose interpolation table are closer to the observed values and have better statistical metrics (0.39 for FB, 0.56 for NMSE, 0.72 for FAC2) than that of RIMPUFF (0.53 for FB, 0.76 for NMSE, 0.65 for FAC2).

RIMPUFF模型快速剂量计算的优化及比利时现场试验评价
Risø Mesoscale PUFF模型(RIMPUFF)是一种拉格朗日大气色散模型,它使用连续的高斯PUFF来模拟意外释放,广泛应用于核应急中。RIMPUFF可以根据实时烟雾大小和烟雾与监测站的距离,利用其剂量计算模块内的剂量计算插值表快速计算出剂量结果,但结果存在偏差。为了提高快速剂量计算要求下剂量计算结果的准确性,本文利用三维积分剂量计算方法,提出了一种新的剂量计算插值表。并与比利时的田间试验结果进行了比较。为了评估优化的质量,将新插值的剂量结果与RIMPUFF、三维卷积方法和现场实验结果进行了比较。比较表明,新剂量插值表的剂量结果更接近于观测值,具有更好的统计度量(FB为0.39,NMSE为0.56,FAC2为0.72),而RIMPUFF (FB为0.53,NMSE为0.76,FAC2为0.65)。
