摘要：
A method of manufacturing a nuclear fuel element which contains a pre-activated non-evaporable getter material such that the getter material starts to sorb gas at a temperature lower than the temperature at which the fuel element walls start to sorb gas which getter action at least partially takes place at subatmospheric pressure.
