CHP can produce electricity energy and make full use of the waste heat energy. Hence its total thermal efficiency is much more than the traditional energy conversion plant.

CHP既能发出电能，又能充分利用余热能量，使其总的热效率远远超过传统的能量转换装置。

Japan itself had a Level 4 accident in 1999, when three workers preparing fuel for a reactor at a Japan Nuclear Fuel Conversion plant triggered a nuclear chain reaction, called a criticality.

日本在1999年就曾发生过一次4级核事故（又称“东海村核事故”——译注），当时在日本核燃料转换公司（Japan Nuclear Fuel Conversion）的一个燃料厂内，三名正在为反应堆准备燃料的工人引发了一次链式核反应，使反应堆达到临界状态。
