为了确保核电站的安全，法国电力公司使用射线检测进行系统的管道控制。管道所处的极端温度和压力条件可能会产生必须检测和表征的结构缺陷。为了提供有关检查能力的有价值的证据，EDF参与了射线照相数据模拟软件（MODERATO）的评估。根据EDF的要求，整个射线照相过程是根据其物理行为建模，并结合新的优化自适应技术，以减少执行时间，使计算时间保持可接受的。根据EDF的需求，来源是铱和钴。可以模拟任何尺寸或形状的物体和缺陷，通过其CAD描述进行描述。它适用于模拟铸造弯头或焊接等复杂对象。探测器由胶片和铅屏组成，可以组合使用。该模型是完全微观的，是基于M...
To ensure security on nuclear power plants, Electricite de France uses radiographic inspection for systemmatic pipe control. The extreme temperature and pressure conditions to which pipes are submitted may generate structural defects that must be detected and characterized. In order to provide valuable evidence on inspection capability, EDF is involved in the evaluation of a radiographic data simulation software (MODERATO). According to EDF’s requirements the whole radiographic process is modeled according to its physical behavior and incorporates new optimization adaptive techniques to decrease execution time so that computation time remains acceptable. According to EDF’s needs sources are Iridium and Cobalt ones. Objects and flaws of any size or shape, described by their CAD descriptions, can be simulated. It is suitable for simulating complex objects like casted elbows or welding. The detector consists in films and lead screens that can be combined. The model is completely microscopic and is based on M...
