Entergy Vermont Yankee takes a leak into the future

The Vermont Yankee nuclear power plant is shutdown, no longer generating power and starting the decommissioning process. And Entergy VY is still struggling with a persistent ground water intrusion problem (think very leaky basement) in and through the nuclear reactor turbine building.curleyleaks

Back when the plant was operating, there was, it seemed, always a steady drip, drip, drip of news coming out of the troubled plant — a high temperature electrical fire here, a decayed cooling tower collapse there, and forty mysterious underground pipes “discovered” as  the source of radioactive tritiated water leaks — just to name a few of the ‘highlights.’ So the current radioactive water intrusion is only the latest in a long history of mishaps.

Happily Vtdigger.com reports VY officials think they have gotten a handle on the rising tides: “Vermont Yankee administrators say they’re getting a stubborn groundwater intrusion problem under control and are no longer pursuing a proposal to discharge radioactive water into the Connecticut River.”

Early this spring Entergy bought homeowner-grade kiddie pools (the NRC actually approved their use for this purpose) to hold the overflow. The pools were then abandoned in favor of more durable rubber storage bladders; gallons of contaminated water were shipped out by tanker truck, an expensive task. And now reports suggest the company will no longer pursue state permission to dump its tainted water into the Connecticut River.

The aggressive flow of water, at its height in February, was as much as 3,000 gallons a day. Yet  officials maintain: “Simply sealing “a number of cracks” in the turbine building has helped.”

And the Entergy VY spokesflack brags: “We had a plan, we implemented the plan, and the plan worked.”FreeVYpoolz

Aw come on, “We had a plan!”  Bah! I think they are winging it –right from the time they rushed out to buy their first kiddie pool to capture overflows of radio-active water.

And now, what VY fails to mention and the reporter at Vtdigger.com definitely should have noted is that Vermont and most of the Northeast are in the midst of record-breaking drought!   Vermont has seen record low rainfall, with the drought  even more severe in Southern New Hampshire and Western Massachusetts.

Ground water levels are low throughout the region — therefore groundwater intrusion at VY’s turbine building would be record low. No water = no leaks!

But Entergy is decommissioning and headed out VY’s back door, pausing just long enough to patch a few cracks in the ‘basement,’ bless Mother Nature for the lack of rain, and cross their corporate fingers. I wonder if part of their plan includes setting up the kiddie pools again next spring?

 

NRC praises ‘flexible’ strategies

Once in a while, just to see what I can see I’ll take a look at the US NRC blog. It is a special place where it almost seems believable that everything nuclear is always under control, always has been and always will be  — forever and ever.FukushimaMeltdown101113 However, a recent NRC post, on the anniversary of the Fukushima disaster tells me  “…great strides” have been made in the past five years. The NRC is getting even better!

A key lesson from the accident was that plants must be prepared for events not contemplated when they were designed and constructed. Plants’ strategies to address external events must be flexible enough to deal with variety of circumstances.

VYkidpoolAll that would be much more reassuring if  images of Entergy’s half dozen or so  kiddie pools full of tritiated water at Vermont Yankee weren’t still fresh in the mind of Vermonters.VYkidpool2 Granted Entergy’s plant is not operating but this can’t be what the NRC meant by flexible strategies.
