Palisades Nuclear Reactor (Unit 1) had to be manually tripped due to cycling of a Turbine Governor Valve. A rapid cycling valve causes instability in a system which must be stable to ensure safety, as well as predictability and efficiency.

It is mind-blowing that Entergy, with its headquarters in the “Big Easy” (New Orleans) through cost-cutting, negligence, etc., could cause a nuclear disaster which could make Chicago, Kalamazoo, Grand Forks, Michigan, Gary Indiana, and much more uninhabitable, along with poisoning the water supply of Lake Michigan and other Great Lakes. Impacts depend largely on wind direction. From the Windscale, Chernobyl and Fukushima nuclear accidents, we know that there can be impacts 1000 miles and more away. For the official fallout zones, see here: http://action.psr.org/documents/map/index.html

The shape of the fallout plume will depend of wind direction and variability:

Radiation contamination from the Chernobyl nuclear power plant accident in May 1986 lasts longer and spread further than most of us can imagine. After explosions at the plant, people in the surrounding area were evacuated and had to settle elsewhere. An exclusion or no-go zone was established in Ukraine and Belarus that stretches over 4,700 km2 (1,814 square miles). Much of this vast area cannot be repopulated for tens of thousands of years.” Original map overlay, text and more here: https://www.greenpeace.org/archive-international/en/campaigns/nuclear/nomorechernobyls/exclusion-zone-comparison-map/

Although not perfectly clear on the map above, Palisades sits on the coast of Lake Michigan:

Palisades Nuclear Reactor had to be manually tripped due to cycling of a Turbine Governor Valve.

A rapid cycling valve causes instability in a system which must be stable to ensure safety, as well as predictability and efficiency. This could be either a mechanical failure, or a failure of the electric control system.

REACTOR TRIP DUE TO CYCLING OF TURBINE GOVERNOR VALVE

At 2028 [EST] on January 3, 2019, with the reactor at 85% power, the reactor was manually tripped due to cycling of Turbine Governor Valve #4. The trip was uncomplicated with all systems responding normally following the trip. Investigation of the cause of the valve cycling is ongoing.

“All full-length control rods inserted fully. Auxiliary Feedwater System actuated as designed in response to low steam generator water levels. Operations stabilized the plant in Mode 3 (hot standby). Decay heat is being removed by atmospheric dump valves.

“This condition has no impact to the health and safety of the public.

“The licensee notified the NRC Senior Resident Inspector.

“This event is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A).”

THIS POST WAS DONE BY REQUEST. WE HAVE WASTED PRECIOUS YEARS AND ENDLESS HOURS ON NUCLEAR TOPICS TO NO AVAIL. THE MAJORITY OF THE POPULATION REMAINS IN DENIAL AND PREFERS TO WATCH FOOTBALL, AND WARM BAR STOOLS AND CHURCH PEWS. THEY WILL GET THEIR JUST DESERTS BUT FUTURE GENERATIONS, WILD LIFE AND THE ENVIRONMENT WILL ALSO PAY. Message to church pew warmers: “faith, if it has no works, is dead in itself“.
