Another Nuclear Power Plant to Retire Early -- This Time in Iowa

NextEra Energy Inc. plans to halt commercial operations at the decades-old Duane Arnold nuclear plant in late 2020
and is shortening a power-purchase agreement with utility Alliant Energy Corp. by five years, according to a statement Friday.

Alliant will pay NextEra $110 million in September 2020 and buy 340 megawatts of power from four of the company’s wind projects as part of the deal to end the power-purchase agreement early.

[ Alliant buys a majority of DA's output and said in Jan of this year they wanted to purchase less expensive energy for their customers. ]

Iowa nuclear plant may close in 2025

Foss said Alliant has not made a final decision on whether it will renew the contract, but lower costs for other forms of energy mean the company has looked at alternatives.

“The cost of wind energy right now has really dropped as well as the cost of natural gas to be at levels where they are competitive and have never been before. We are continuing to pursue different options for our customers to make sure that they get the best value,” Foss said.

Nuclear plants built since the 1960s have struggled to stay competitive in an era of cheap natural gas and wind,
with many knocked aside well before the end of their useful lives.
[ The end of their useful lives began on the day ground was broke. ]

[ Byyyyeeee ]

[ There are currently 22 spent fuel casks in horizontal containment. ]
[ zoom out, see all the farmland. ]

[ Iowa is a major corn, soy and oats producer. Wonder if there has ever been a study on radionuclides in soil around the unit. ]

[ This unit is scheduled for refueling 10/03/18. Like filling the cars gas tank before you send it to the junkyard. ]

[ Considering that approx 1/3 of the fuel is replaced each RFO and this unit is on a 24 month cycle, on closing DA will have. ]

[ 1/3 fresh fuel from the 2018 fall RFO, 2yr old fuel ]
[ 1/3 used fuel from the 2016 fall RFO, 4yr old fuel ]
[ 1/3 spent fuel from the 2014 fall RFO, 6yr old fuel ]

[ Don't forget the spent fuel pool has many years of fuel in it. ]

[ DA is a GE BWR 4 - Mark 1 containment, so the spent fuel pool is on the refueling deck, same as Fuku-go-boom. ]

[ Notice in the Bloomborg article title they state the unit is "retiring early", actually the unit began with a 40 yr license in 1974, and was granted a 20 year extension in 2010 by the Nuclear Rubberstamp Committee. So this unit will actually be shutting down  6 years after it's designed expiration date. ]
Merry-go-round starting.

Oyster Creek to be sold: Holtec to take down plant in 8 years
Amanda Oglesby, Asbury Park Press Published 9:32 a.m. ET July 31, 2018 | Updated 5:25 p.m. ET July 31, 2018

LACEY - A Camden-based company specializing in nuclear and solar energy intends to purchase Oyster Creek Generating Station and decommission the nuclear plant in eight years, more than half a century earlier than previously planned.

The deal will transfer ownership of Oyster Creek to Camden-based Holtec International. The company will also take over the plant's spent nuclear waste and its decommissioning trust fund, worth more than $982 million. Exelon, the plant's current parent company, estimated decommissioning and site restoration costs would near $1.4 billion.

Exelon's original plan including storing the plant for more than a half-century to allow radiation levels to drop and its trust fund to accrue more money before taking down the facility.
