蒸汽发生器的可靠性是影响核电站经济运行的因素之一。不考虑检修工作本身的花费,就是由于蒸汽发生器损坏所造成的停电损失也是很大的。根据国外的资料,蒸汽发生器的平均价格约为10美元/千瓦(电),因为停堆赔偿电能方面的损失费可达0.01美元/(千瓦·小时)或者还要高些。由此可见,为检修蒸汽发生器传热管而停堆1000小时的耗资将等于该反应堆所有蒸汽发生器的价值。 The reliability of steam generator is one of the factors affecting the economic operation of nuclear power plants. Regardless of the cost of maintenance work itself, the power outage caused by damage to the steam generator is also significant. According to foreign sources, the average cost of a steam generator is about $ 10 / kWh, since the cost of decommissioning can be up to $ 0.01 / kWh or even higher. It can be seen that the cost of shutting down 1000 hours for servicing steam generator heat transfer tubes will be equal to the value of all steam generators in the reactor.
