Nuclear agency head to visit flooded Nebraska reactors

FORT CALHOUN, Neb | Fri Jun 24, 2011 7:14pm EDT

FORT CALHOUN, Neb (Reuters) - The chair of the federal Nuclear Regulatory Commission will arrive in Nebraska Sunday to monitor preparations against Missouri River flooding at two Nebraska nuclear power plants, officials said Friday.

NRC Chair Gregory Jaczko will visit the Cooper Nuclear Station south of Omaha Sunday and the Fort Calhoun plant north of Omaha Monday, said agency spokesman Victor Dricks.

During both visits, Jaczko will also be talking with NRC resident inspectors-- the agency staff who work on-site every day -- and plant officials, Dricks said.

Flood water up to 2-feet deep is standing on the site of the 478-megawatt Fort Calhoun plant, operated by the Omaha Public Power District, the NRC said Wednesday.

The utility has erected a water-filled berm around vital areas of the plant -- which shut in early April to refuel -- to protect the containment building and auxiliary buildings from up to six feet of water.

Heavy rains and snow melt have flooded the Missouri River valley, threatening towns from Montana to Missouri.

An NRC inspection at Fort Calhoun two years ago indicated deficiencies in the flood preparation area, which have now been remedied, the agency said.

The rising river is not expected to reach vital equipment at the 800-megawatt Cooper plant, located near Brownville, Nebraska and operated by the Nebraska Public Power District, the NRC said. Cooper is running at full power.

During the Fort Calhoun stop, the chairman will meet first with U.S. Army Corps of Engineers officials, then take a helicopter tour along the Missouri River to provide an overview of the flooding and measures being taken. Following the plant visit he will meet with executives of the utility.

"Both plants remain under the 'unusual event' declarations, the lowest of four levels of emergency notification," Dricks said. "We are maintaining close communications with the National Weather Service and the Army Corps of Engineers."

Fort Calhoun will stay shut down until the water recedes, Dricks said..

Don’t worry. It will all turn out to be “perfectly safe.” After all, that’s what they said about Japan…

Each geographical location is vulnerable to specific kinds of disasters. On the west you’ve got earthquakes and fires as well as hurricane winds and floods. We’ve got the same here in the Midwest less the hurricanes and mass fires. If we fail to learn from this experience and improve our situations in the future then we will leave the rising generation with the deficiencies of the elder generation’s lack and complacency.

What makes the Missouri River Flood of 2011 so important to learn from is that it is man-made. Sure, it’s spawned by natural events of snow melt and heavy rains. However, decisions at certain times have given way to what we have now. We can’t blame nature for this one. We must learn to strengthen levees, widen reservoirs, diversify snow melt paths and build flood plain towns on higher elevations. Yes, it’s a huge expense but isn’t it worth it?

We are e pluribus unum – out of many, one. Let’s start acting like it and work together to improve the land in which we live for all.

The nuclear reactor at the Fort Calhoun plant was designed and built by Combustion Engineering (CE). The design differs completely from that of the Chernobyl and Fukashima (General Electric BWR) designs. It also differs significantly from the Babcock & Wilcox design at Three Mile Island.

I know. I was a startup engineer for CE at Fort Calhoun, was there for the initial startup and testing, and stayed on as the CE Resident Manager, planning and conducting the first refueling of the unit.

It was there I met Gary Gates. As I recall, he was a pimply-faced young engineer working in the OPPD Reactor Engineering Group. Corporate CE was concerned that a small utility like OPPD might not have the resources necessary to run a nuclear plant, but dealing daily with OPPD personnel on and off-site I found that professionals like Gary were dedicated to the safe operation of the nuclear unit. Thus it was small surprise to learn that Gary rose to be CEO of OPPD. Almost makes me sorry that I didn’t accept the job offer at the time.
