Palisades and Pressurized Thermal Shock: 3/18 Entergy Statement

The following statement was released today by Entergy concerning the Palisades plant both on its dedicated Palisades website and also on its Palisades Facebook page.

Press Statement, Entergy Nuclear 3/18

In regards to the recent media coverage of the Palisades Nuclear Power Plant and the industry topic of pressurized thermal shock, Entergy Corporation issued the following statement from Tony Vitale, Palisades’ site vice president:

"The Palisades nuclear plant is a safe and secure facility, and we have an NRC license to operate this facility through 2031.

The Nuclear Regulatory Commission has str...ict rules, regulations and limits for all aspects of nuclear plant operations. This includes a program to monitor nuclear power plant reactor vessels and the potential impact of a rare accident scenario – pressurized thermal shock – in which a large amount of cold water is injected into the reactor resulting in rapid cooling of the reactor vessel.

This is not a new topic or one that is unique to Palisades. In fact, for decades pressurized thermal shock has been well understood and well monitored by the owners and operators of the nation’s pressurized water reactors.

Every pressurized water reactor plant in the nation is required by the NRC to continually update its calculations to confirm reactor vessel strength – meaning every plant must conduct periodic reactor vessel inspections and analyze reactor vessel samples. Consistent with these NRC requirements, Palisades will conduct these inspections and analysis during our refueling outage this fall.

We have every reason to believe the test results will again demonstrate the safety and strength of the Palisades reactor vessel – which will enable us to continue operating through the end of our license in 2031. We will submit an updated evaluation to the NRC for its review in the spring of 2014.
Our unrelenting commitment and focus are on operating Palisades at the highest levels of safety and reliability – now and for many years to come.”
