CRUD is a term used to describe the Corrosion Related Unidentified Deposits, which forms on the coolant facing structural materials in high temperature water circuits of pressurized water reactors (PWRs). Its effect is detrimental because it can affect the transport and possible incorporation of radioactive species in the primary loop, it can cause a reduction in heat transfer at the fuel pins surfaces and steam generator tubing and it's also responsible for the axial offset anomaly.

CRUD是一个术语，用于描述与腐蚀相关的未识别沉积物，它形成于压水堆高温水回路中面向冷却剂的结构材料上。它的影响是有害的，因为它会影响放射性物质在主回路中的运输和可能的结合，它会导致燃料棒表面和蒸汽发生器管道处的传热减少，并且它也是轴向偏移异常的原因。
