Small is beautiful for federal funds

The US Department of Energy (DoE) is to help push forward the manufacture of small modular nuclear reactors through new cost-sharing arrangements with private industry to support design and licensing activities.

The DoE intends ultimately to fund up to two designs for small modular reactors (SMRs) through a cost-shared partnership which will support first-of-a-kind engineering, design certification and licensing. To that end, it has issued a draft Funding Opportunity Announcement (FOA) to solicit inputs from industry in advance of the full FOA, aiming at a deployment date for the reactors of 2022.

Small, compact reactors of around 300 MWe in capacity - around a third of the size of a typical commercial nuclear power plant - can potentially offer a range of strengths in terms of safety, construction and siting as well as potential economic benefits. Their modular 'plug and play' nature means that they could be made in factories and transported to generation sites, offering economies of scale and reducing both capital costs and construction times. Their small size makes them suitable for small electric grids and locations that cannot support large reactors, while offering the flexibility to install units individually or as modules in a larger generating complex, adding more modules incrementally as required. As well as using a simpler reactor design, SMRs can incorporate a high level of passive or inherent safety in the event of malfunction.

The NRC is currently involved in pre-application activities on both designs in anticipation of a design certification application for the NuScale reactor in the first months of 2012, followed by one for the mPower design towards the end of 2013.
