Since the world's first commercial nuclear power plant (NPP) was commissioned in 1956 (Calder Hall nuclear power station, UK), the world's NPPs have evolved in the direction of increasingly large reactors, which tend to require costly and highly specialized construction and assembly equipment, labor and supply chains.  There have also been many instances of the nuclear regulatory regime changing during the plant construction process, which has required significant change orders.  These and other challenges in developing new large reactor plants has contributed to the nuclear industry's "bad marks" for significant construction delays and cost overruns in many parts of the world over the past few decades. 

Despite the many challenges of developing large reactor nuclear power plants, these large plants have proven to be safe, reliable, efficient and a source of low-carbon electricity.  Furthermore, on a life-cycle basis large reactor nuclear plants offer cost-competitive generation and can offer significant economies of scale given that NPPs have operating lives of more than 60 years.  In many cases, large reactor NPP sites are configured with multiple reactors and can be designed to be scaled-up through phasing in additional reactor units in the future in accordance with electricity market plans and models.  Large reactor NPPs, operating at high capacity factors, are an ideal generation technology for the purpose of providing for the base load generation supply in a country's or region's energy markets.  However, large reactor NPPs can also be operated as "load following" plants, as has been demonstrated in France after the significant growth of intermittent renewables generation.

In most cases the significant up-front capital costs need to be amortized over a long time horizon (e.g. 20 - 30 years).  Traditional "ringfenced project financing" from commercial banks and international finance institutions (IFIs) is categorically unavailable for nuclear power projects.  Therefore, there has been a tendency for many of the recent new-build NPPs to be financed through export credit (typically loans and guarantees from ECAs and EX-IMs), sovereign loans and other financing and guarantees arranged by the exporting country in the case of a state-to-state transaction, or the exporting company(-ies) in the case of a commercial transaction.

In the large reactor nuclear generation segment, DCS provides expert advisory services in the following specific areas:
