APS seeks SLR to keep Palo Verde operational into the 2060s
Arizona Public Service has informed the Nuclear Regulatory Commission of its intention to renew the operating licenses of the Palo Verde nuclear power plant’s three reactors for a second 20-year term, which could extend operations at the facility into the 2060s.
According to the announcement, APS won’t submit the subsequent license renewal application to the NRC until late 2027. The renewal would allow Unit 1 to operate through 2065, Unit 2 through 2066, and Unit 3 through 2067.
