The scale is unlike that of an existing commercial nuclear plant.

其规模不同于现有的商业核电站。

So we have to invest in large-scale commercial plants, which are often too risky for traditional investment.

所以我们不得不投资大型商业工厂，这对传统投资来说风险往往太大。

And to take it from proof of concept to a pilot-scale prototype to a full-scale commercial plant takes years.

从概念验证到中试规模原型再到全面的商业工厂需要数年时间。
