从反应堆位置上释放出来的氚以什么状态存在,关系到它的释放途径与安全评价问题。通过在高通量工程试验反应堆(HFETR)上试验证实,在正常运行条件下,释放到冷却剂中的氚90％以上是以液体形式出现的,其余是以气态氚形式出现的,而气态氚中元素态氚有很高比例。从冷却剂中氚可能存在状态来看,从氚化水(HTO)状态和氚气(HT)状态对人体危害程度来看,与反应堆有关的安全评价假定所有从反应堆位置上释放的氚均以HTO状态存在是合适的。 The state of tritium released from the reactor site is related to its release route and safety assessment. It has been confirmed by experiments on a high-throughput engineering test reactor (HFETR) that under normal operating conditions, more than 90% of the tritium released into the coolant is in liquid form and the rest is in the form of gaseous tritium, while gaseous tritium There is a high proportion of tritium in the elemental state. Judging from the possible presence of tritium in the coolant, the reactor-related safety assessment, based on the degree of hazard to human health from tritiated water (HTO) and tritium (HT) states, assumes that all tritium released from the reactor site is HTO status is suitable.
