<">
In a stunning announcement, Exelon Generation, which operates the largest
U.S. fleet of nuclear plants - 21 reactors at 12 facilities in Illinois,
Maryland, New York, and Pennsylvania - said it will retire the Byron and
Dresden generating stations next fall for economic reasons.
(...)
The Dresden Generating Station (Figure 1) has two operating boiling water
reactors that combine for a total net generating capacity of 1,845 MW. Unit
2 began commercial operation on April 13, 1970, while Unit 3 entered
commercial service on July 22, 1971. The units are licensed to operate
until Dec. 22, 2029, and Jan. 12, 2031, respectively.
(...)
The Byron facility (Figure 2) is also a dual-unit plant. It has pressurized
water reactors and a total net capacity of 2,347 MW. Unit 1 entered
commercial operation on Sept. 16, 1985, and Unit 2 followed on August 2,
1987. The reactors are licensed through Oct. 31, 2044, and Nov. 6, 2046,
respectively.

Possibile comunque che la chiusura sia evitata grazie a incentivi pubblici:
 
<">
This is not the first time Exelon has announced plant closures due to
economic struggles. In June 2016, the company said it would permanently
close the Quad Cities and Clinton nuclear plants because they had lost a
combined $800 million during the previous seven-year period. The
announcement spurred quick action in the Illinois legislature, and in
December that year the Future Energy Jobs Bill (SB 2814) was passed, which
saved the facilities.

Nel frattempo un'altra centrale chiude prima dello scadere della licenza:

<">
The Duane Arnold Energy Center (DAEC, Figure 1) - a 615-MW nuclear power
plant located in Palo, Iowa - will reportedly not restart after high winds
caused extensive damage to the station’s cooling towers. The plant owner,
NextEra Energy Resources, had planned to retire the unit on Oct. 30, but
after assessing damage caused by an Aug. 10 derecho, the company decided to
accelerate the retirement process.

"The companies have now agreed to shorten the term of the existing
  PPA by five years in exchange for a USD110 million buyout payment,
  to be made by Alliant in September 2020."
 
Notare che in Iowa, senza PPA, non si vende energia elettrica.
Tra l'altro NextEra non e' affatto una azienda nucleare, e pare
che abbia acquistato DAEC proprio per poterne anticipare la
chiusura ed avere campo libero nel mercato elettrico dell'Iowa.
 
Quindi e' fin dal 2018 era stato decisa la chiusura entro il 2020.
 
Secondo lei, invece avrebbero dovuto riparare le torri di
raffreddamento per solo 2 mesi di funzionamento residuo ?
Strana logica.

Il mio pianto per una simile perdita potrebbe alimentare una centrale 
idraulica a lacrima fluente.

 percio' fino al 2034. (...)
 
Quindi, a prescindere dalla questione dei danni, la centrale ha comunque
chiuso ben prima dello scadere della licenza. Questo è il punto.
