Quite a lot of hurdles for NuScam’s Utah project, and only 27 of UAMPS members signed up

UAMPS Mulls Downsizing Nuclear Project, Power, 11 Nov 20“…………..So far, the company has marked key regulatory milestones. On Aug. 28, notably, NuScale’s 50-MW (160 MWth) module became the first SMR to receive a final safety evaluation report (FSER) from the NRC as part of a Phase 6 review—the last and final phase—of NuScale’s Design Certification Application (DCA).
The latest power uprate will be reviewed by the NRC as part of a Standard Design Approval (SDA) application, which NuScale on Tuesday said it is schedule to submit in 2022. However, Hughes said that while NuScale has not yet made a final decision on the size or configuration that will be reflected in the SDA application, it will seek approval of 250 MWth modules. “Our final decision will be announced soon,” she said.

NuScale’s Announcement Gives UAMPS’ Options to Downsize Carbon-Free Power Project When UAMPS will submit a COLA for its Carbon Free Power Project (CFPP), a 12-module NuScale power plant that is developing for a site at an Idaho National Laboratory (INL) site in Idaho Falls, Idaho, is not clear. UAMPS has so far developed the much-watched project as a 720-MWe plant, and it has said it expects the first of the 12 proposed NuScale modules could be operational in 2029 with the other 11 modules operational in 2030. But NuScale’s new power increase and its launch of smaller plant sizes now gives the project much-needed flexibility that could affect it current timetable. The newly announced uprate is significant because it “facilitates plant downsizing,” UAMPS told POWER in a statement on Tuesday. “An important early task in the UAMPS [CFPP’s] next phase will be evaluating these new options in plant size and configuration. UAMPS will evaluate the possibilities of building a [308-MWe] 4-module or [462-MWe] 6-module plant instead of a 12-module plant,” it said. UAMPS, notably, just wrapped up the first phase of the CFPP on Oct. 31, securing financial commitments for a potential 720-MW plant from 27 of its 48 members, which are mostly cities in Utah but also scattered across California, Idaho, Nevada, New Mexico, and Wyoming. During the tumultuous first phase, at least eight cities—Lehi, Logan, Murray, Kaysville, Bountiful, Beaver, Heber, and Salmon River Electric—dropped out of the the project, and at least one, Idaho Falls halved its share. The withdrawing cities cited a long list of reasons for their reluctance to commit to the project, but costs—which could increase for remaining subscribers—and uncertainty led their concerns. ….. The next off-ramp will likely be in April 2023, when UAMPS is expected to submit the application to the NRC. The final off-ramp would be in December 2025, before the start of the construction period. As POWER has reported, the 720-MWe CFPP is currently estimated to cost $6.1 billion, and UAMPS is expected to shoulder $4.76 billion of that figure, which is based on a Class 4 estimate (and could decrease by about 10% or increase by 30%). The Department of Energy (DOE) will fund the remaining $1.355 billion through an award announced on Oct. 16. The award, which will be subject to yearly Congressional appropriations, replaces the DOE’s Joint Use Module Plant (JUMP) program. ……. On Tuesday, UAMPS again stressed that the project’s LCOE (Levelised Cost Of Energy )will play a crucial factor in any decisions it makes. Before it can agree to a change in plant size or configuration—including to move forward with NuScale’s newly launched smaller power plant solutions—“UAMPS would have to be assured that the [LCOE] of $55/MWh (or lower) would be preserved. UAMPS would also want assurance that the current schedule/timeline would be followed,” the agency said. ……. |
