船用堆一旦发生放射性泄漏事故，放射性核素将通过各种途径释放至工作舱室，极有可能导致船员受到超剂量内、外照射，为科学估计与评价船员受照剂量、有效开展医学应急处置，通过分析反应堆堆芯放射性核素释放机理及污染舱室主要核素类型与分布，利用Origen2程序计算某型压水堆不同运行功率连续运行不同时间时主要裂变产物积存量，利用Matlab软件对裂变产物积存量与运行时间的函数进行最小二乘法拟合，建立船用堆变工况运行条件下主要裂变产物积存量以运行功率和时间为变量的拟合函数，进而依托船上固设的碘-131探测装置确定污染舱室辐射场绝对分布，建立了船用堆放射性泄漏事故污染舱室辐射源项的反演技术方法，并利用Visual C＋＋编制程序实现了船用堆放射性泄漏事故船员剂量快速估算。

Marine nuclear power plant in the event of a radioactive spill , radionuclide release through a variety of channels to work compartments , is very likely to lead to the crew by the irradiation or external overdose , ex-posure doses for scientific estimation and evaluation of crew to effectively carry out the medical emergency re -sponse , continuous operation at different times through the analysis of the reactor core radionuclide release mechanism and pollution compartments radionuclide type and distribution , using Origen2 procedure to calculate the cumulative amount of major fission product at a certain type of pressurized water reactor , using matlab soft-ware to estimate the fission product cumulative amount as a function of the run time and the operating power by a least squares fit to establish marine nuclear power plant operating conditions , and relying on the onboard solid set the iodine-131 detection devices to determine the pollution compartments radiation field absolute distribu -tion, so as to establish marine nuclear power plant radioactive spill contaminated compartments radiation source by inversion technique method , and to realize fast dose estimation of sailor used Visual C ++.
