multiple inspections, a small crack along a nozzle weld was identified at the
bottom of the tank. The crack is believed to be the cause of a leak that led to
the plant’s shut down on May 5th.
Terry Young, Vice President of Communications
for Entergy Corporation which owns Palisades, says they’ve made a decision to completely
replace the tank bottom and reconstruct the subfloor: the 300,000 gallon aluminum
tank lies on a bed of sand.
“Over time, as water leaked through the bottom of that tank, some sand had erroded over time so it allowed the bottom of the tank to flex more than designed.”
the entire floor of the tank, operators can access and replace the subfloor -
critical to the stability of the tank itself. The extensive replacement effort should
take a few weeks. Cost estimates for replacement of the tank, which sits above the
control room, have not yet been identified.
“We don't really have a cost estimate but ultimately it's not really about cost in this scenario, it's about identifying a solution for this problem once and for all; that for us is the most important issue.”
Young if Palisades would have considered replacing the tank without recent pressure
from St.Joseph Congressman Fred Upton and others to find a permanent resolution
to a problem than has plagued the aging nuclear plant.
“We were seeking a permanent solution because obviously when we are generating electricity to make money in a safe manner and when we're not operating that's not good for revenue.”
it a once and for solution to the tank’s leaks which have led to multiple plant
shutdowns. While Young says Palisades will not be fined by the NRC for this leak,
that point remains unclear.
“Once our review is complete we will determine what enforcement action would be adequate for what occurred.”

of 79 gallons of diluted radioactive water into Lake MI was well below NRC
