would nuclear power help to extend lifetime of a plant?
Yes, There is a research into Light water reactor sustainability.
Nuclear power
the cost of extending plant lifetimes is competitive with other electricity generation technologies, including new solar and wind projects. In the United States, licenses of almost half of the operating nuclear reactors have been extended to 60 years.
The U.S. NRC and the U.S. Department of Energy have initiated research into Light water reactor sustainability which is hoped will lead to allowing extensions of reactor licenses beyond 60 years, provided that safety can be maintained, to increase energy security and preserve low-carbon generation sources. Research into nuclear reactors that can last 100 years, known as Centurion Reactors, is being conducted.
