Especially in USA, nuclear reactors are getting very old – past their use-by dates

 Notably, 88 of the 92 reactors in the U.S. have received approvals to operate for up to 60 years, and some have applied for additional 20-year extensions to operate for up to 80 years

How Old Are the World’s Nuclear Reactors?, Elements, June 27, 2023, By Govind Bhutada

“………………………………………………… The Age Distribution of the Global Reactor Fleet

Nuclear power saw a building boom in the 1970s, 80s, and 90s as countries expanded their energy portfolios and sought to capitalize on the advancements in nuclear technology. As a result, the majority of the world’s nuclear reactors began operating during this period.

Of the total of 422 reactors, 262 reactors have been in operation for 31 to 50 years. In other words, about 62% of all current nuclear reactors were connected to the grid between 1973 and 1992.

Nuclear power’s growth slowed down at the turn of the 21st century, with decreasing public support and increasing concern over nuclear safety. As a result, only a small number of reactors fall into the 11-to-20-year-old age group.

The oldest operating reactors (five of them) are 54 years old and entered commercial service in 1969. Two of these are located in the United States, two in India, and one in Switzerland.

How Long Can Nuclear Reactors Last?

Although specific lifespans can vary, nuclear reactors are typically designed to last for 20 to 40 years.

However, reactors can operate beyond their initially licensed periods with lifetime extensions. Extending reactor lives requires rigorous assessments, safety evaluations, and refurbishments.

Some countries have granted license renewals for aging reactors. Notably, 88 of the 92 reactors in the U.S. have received approvals to operate for up to 60 years, and some have applied for additional 20-year extensions to operate for up to 80 years…… https://elements.visualcapitalist.com/how-old-are-the-worlds-nuclear-reactors/
