U.S. Energy Information Administration, May 12, 2017
EIA’s 2017 Annual Energy Outlook Reference case assumes that about 25% of the nuclear capacity now operating that does not have announced retirement plans will be removed from service by 2050. Nearly all nuclear plants now in use began operation between 1970 and 1990. These plants would require a subsequent license renewal before 2050 to operate beyond the 60-year period covered by their original 40-year operating license and the 20-year license extension that nearly 90% of plants currently operating have either already received or have applied for. The AEO2017 Reference case projections do not envision a large amount of new nuclear capacity additions. By 2050, only four reactors currently under construction and some uprates at existing plants are projected to come online.
