请问这个怎么翻译? It is very important to notice that the reactor temperatures (inside and skin) and pressure shall be in accordance with the temperature/pressure charts provided by the reactor supplier at all times. The minimum pressurization temperature (MPT) of the reactor shall be carefully respected. MPT is related to the ductile-to-brittle transition temperature of the reactor material. Note that low alloy steel reactors are subjected to temper embrittlement ; as a consequence MPT is not only a function of the metallurgy of the vessel, but it also varies (increases) as the vessel ages. Hydrogen dissolved in the reactor wall is another factor of embrittlement, which is also addressed by MPT. In case MPT is higher than 130°C, the reaction section shall be pressurized at the maximum allowable pressure at 130°C (typical is ¼ of the normal operating pressure). 什么意思? 查看更多4个回答 . 5人已关注
