Dominion Energy has filed an software to increase the working licenses for 2 45-year-old nuclear reactors on the Surry Power Station by 2052 and 2053—when they are going to be 80 years outdated.
Surry’s Unit 1 and a couple of, positioned close to Newport News, Virginia, are three-loop Westinghouse pressurized water reactors (PWRs) that started operation in December 1972 and May 1973. The plant’s preliminary licenses, which allowed the models to function for 40 years had been prolonged one other 20 years on March 2003. On October 16, Dominion Energy filed an software with the Nuclear Regulatory Commission (NRC) to increase the working licenses by a further 20-year time period. Unit 1’s present license expires in May 2032, and Unit 2’s in 2033.
Dominion’s Surry nuclear plant is simply the third within the nation to file for a subsequent license renewal (SLR) to increase operation from 60 years to 80 years for the reason that NRC in July 2017 issued its remaining “Subsequent License Renewal Report.” The report is the regulatory physique’s employees’s generic analysis of plant getting old administration applications and serves as steerage for SLR candidates.
In April 2018, investor-owned Florida Power and Light Co. submitted an SLR software for Turkey Point Units three and four, that are additionally three-loop Westinghouse PWRs. If accredited, the present working licenses for the 913-MW Unit three can be prolonged to July 2052, and the 923-MW Unit four, to April 2053. The NRC expects a remaining resolution might come by October 2019.
In July 2018, Exelon Generation and PSEG Nuclear collectively filed an SLR software for Peach Bottom Units 2 and Units three, that are Mark 1 boiling water reactors in southeastern Pennsylvania. If accredited, Unit 2’s license can be prolonged to 2053, and Unit three’s, to 2054.
Dominion in November 2017 additionally notified the NRC that’s its readying to submit an SLR software for its North Anna Power Station Units 1 and a couple of, whose licenses are set to run out in 2038 and 2040. The firm will doubtless file the applying earlier than the tip of 2020.
On Tuesday, Dominion mentioned it plans to spend as a lot as $four billion over the following decade on the relicensing program for Surry and North Anna, which, it famous, “has bipartisan help in Virginia.” Surry’s 1,676-MW is able to offering 15% of energy Dominion’s prospects obtain, it mentioned.
While the proliferation of gas-fired models and renewables have rattled the economics of nuclear vegetation throughout the nation, particularly in aggressive energy markets, the 4 vegetation in search of SLRs all seem to have robust capability elements. Surry 1 operated at 101% in 2017 and 96% in 2016, whereas Surry 2 operated at 93% in 2017 and 77% in 2016, in line with the NRC. Capacity issue is the ratio of the online electrical energy generated, for the time thought-about, to the power that would have been generated at steady full-power operation throughout the identical interval.
Dominion’s software additionally comes on the heels of the commonwealth’s 2018 Energy Plan. The plan, unveiled on October four, requires improvement of 5 GW of utility-owned and utility-operated wind and photo voltaic sources “deemed within the public curiosity.” That will embody 500 MW of rooftop photo voltaic (of lower than 1 MW in dimension). It can even require investor-owned utilities to speculate $1.1 billion in power effectivity applications, and set up cost-recovery constructions for tasks that modernize the grid and help the mixing of distributed power sources.
Dominion owns 100 technology models—a complete of 18 GW—all through the state, together with the Surry and North Anna nuclear models,12 coal models, 4 pure fuel (steam) models, 10 mixed cycle vegetation, 41 combustion generators, 14 hydro, and 4 biomass models.
