23 July 2021 Share Utah Associated Municipal Power Systems (UAMPS) now expects to build six 77 MWe NuScale Power Modules on a site at Idaho National Laboratory (INL), rather than 12 units as previously planned. A 2030 start-up date for the plant - known as the Carbon Free Power Project (CFPP) - is still envisaged. How a NuScale SMR plant could look (Image: NuScale) The CFPP, launched by UAMPS in 2015, was initially envisaged as a 12-unit power plant using 50 MWe NuScale Power Modules. The capacity of the NuScale module - a pressurised water reactor with all the components for steam generation and heat exchange incorporated into a single unit - has since been uprated, firstly to a 60 MWe version and then, in November last year, to 77 MWe per module. UAMPS said it would evaluate options for power plant size - the so-called 4-pack, 6-pack, 8-pack or 12-pack module configurations - to ensure the best overall way to meet the needs of its members.
